**** BEGIN LOGGING AT Mon May 25 02:59:57 2009
May 25 03:00:09 <sammyF> new release coming ?
May 25 03:00:16 <romainguy> no
May 25 03:00:18 <romainguy> just r2
May 25 03:00:49 <sammyF> ah. I only noticed today that it was out, but then I guess it's not THAT old
May 25 03:01:38 <romainguy> it was released at the end of day on Friday, PST
May 25 03:01:46 <sammyF> the Release Notes in the linux zip are still for 1.1 btw
May 25 03:01:50 <romainguy> and it only contains a security fix
May 25 04:33:24 <pawbie> If I want to allow people to reuse a part of my project (parsing a custom file)...  I should be creating an Activity?  I thought it would be an intent, but this filetype has no MIME and I can't see how to specify an extension...
May 25 04:46:15 <NutMonkey> pawbie: I would think you would create a ContentProvider for the file.
May 25 04:47:35 <pawbie> I think so.  I'm working on adding that in now...  hm.
May 25 04:47:48 <pawbie> I did something similar with a custom uri, so I assumed I could do the same thing with a file (with an intent).
May 25 05:21:45 <NutMonkey> I have a ListView with a SimpleCursorAdapter.  I want to setItemChecked() after the query refreshes, but there doesn't seem to be a listener for that?
May 25 05:23:04 <romainguy_> you have to set a data observer on the adapter itself
May 25 05:24:33 <NutMonkey> Thanks, what class are you referring to?
May 25 05:24:36 <wmealing> romainguy, as someone reading on the side, do you know of an example (as I dont know what a data observer is)
May 25 05:24:56 <wmealing> http://developer.android.com/reference/java/util/Observer.html <-- perhaps ?
May 25 05:25:22 <romainguy_> read the documentation.... it's not that hard
May 25 05:25:22 <romainguy_> http://d.android.com/reference/android/database/DataSetObserver.html
May 25 05:25:44 <wmealing> thanks romainguy (i did search for dataobserver.. just didnt come up with that hit.
May 25 05:37:12 <NutMonkey> Why is DataSetObserver a class and not an interface?  What does the default onChanged() do?
May 25 05:38:08 <romainguy_> why would it be an interface?
May 25 05:38:19 <romainguy_> if it was an interface, adding methods to it would be impossible
May 25 05:38:36 <romainguy_> and it doesn't do anything by default
May 25 05:42:14 <NutMonkey> Either way you have to define a class, what's the point of a class that doesn't do anything?
May 25 05:42:30 <romainguy_> "romainguy_: if it was an interface, adding methods to it would be impo"
May 25 05:42:45 <romainguy_> the point is that we'll be able to extend its API in the future without adding new interfaces
May 25 05:44:02 <wmealing> the nice part about android is that there are a lot of helper classes in the framework
May 25 05:44:10 <wmealing> so i end up writing code, then finding out i could have done it easier/with less code
May 25 05:44:15 <wmealing> assuming i used the correct classes
May 25 05:44:26 <wmealing> which is nice, as I now understand how things fit together.
May 25 05:44:31 <NutMonkey> Ah, forwards compatibility, that makes more sense
May 25 05:45:17 <romainguy_> wmealing: we try to make it easy although I have to admit our APIs could be a LOT better
May 25 05:45:29 <romainguy_> (in particular: more consistent and cleaner)
May 25 05:45:54 <wmealing> romainguy, Going to be many changes in that direction ? or are things going to stay how they are ?
May 25 05:46:17 <romainguy_> current APIs are set in stone
May 25 05:46:20 <romainguy_> now they are public...
May 25 05:46:34 <romainguy_> we try to add niceties though
May 25 05:46:41 <wmealing> i'm wondering about updates in "2.0"
May 25 05:46:48 <romainguy_> there's no 2.0
May 25 05:46:55 <romainguy_> for instance in Donut you can write <Button android:onClick="myMethod" />
May 25 05:47:09 <wmealing> ok.
May 25 05:48:26 <romainguy_> right now I"m writing new APIs for Donut
May 25 05:48:32 <romainguy_> and I keep changing them
May 25 05:48:34 <wmealing> i'll rephrase the question, will there be any api changes in the major version updates.
May 25 05:48:45 <wmealing> well, you just answered :)
May 25 05:48:46 <romainguy_> I'm not happy about their ease of use :))
May 25 05:48:53 <wmealing> romainguy, i'm pleased that you are not happy
May 25 05:48:59 <wmealing> romainguy, it means you care and are thinking about it.
May 25 05:48:59 <NutMonkey> A lot of the API I like, but the event handling definitely makes me miss Qt's signals and slots..
May 25 05:49:19 <jsharkey> romainguy_: add an api to query the users IQ  ;)
May 25 05:49:51 <romainguy_> jsharkey: :))
May 25 05:50:08 <jsharkey> before letting them into #androidchat or whatever is it
May 25 05:50:49 <jsharkey> aww that channel is dead, did they move somewhere else?
May 25 05:51:06 <romainguy_> gah
May 25 05:51:11 <romainguy_> finally got something working again
May 25 05:51:17 <romainguy_> I broke everything a few hours ago
May 25 05:52:17 <wmealing> #android :P
May 25 06:26:09 <romainguy_> jsharkey: ?
May 25 06:27:04 <lucius> hi, does anyone how to debug c++ code on android platform?
May 25 06:30:24 <wmealing> lucius, just like you would any other linux platform
May 25 06:30:48 <wmealing> if you like, you can use gdb
May 25 06:31:23 <lucius> but how can i hook up my gdb on os to the program running on android emulator?
May 25 06:31:58 <lucius> take for example, i would like to debug Webkit on android (an application which is part of android)
May 25 06:32:08 <lucius> how can i debug that?
May 25 06:32:31 <lucius> assume i am able to get the source and build android sdk myself locally
May 25 06:34:05 <wmealing> yes.
May 25 06:34:15 <wmealing> one moment
May 25 06:34:26 <lucius> thank you.
May 25 06:34:54 <wmealing> oh, thats ugly, you can't run gdbserver on android
May 25 06:35:10 <wmealing> http://honeypod.blogspot.com/2008/01/debug-native-application-for-android.html
May 25 06:35:11 <wmealing> try that.
May 25 06:35:46 <wmealing> i hope that will get you to where you need ot be
May 25 06:35:53 <wmealing> i'd reccomend you build smaller test cases
May 25 06:35:55 <wmealing> and debug that
May 25 06:36:10 <wmealing> Multi-threaded applications now seem to be supported. The key is to run the GDB client from the one installed in the Android source tree at prebuilt/linux-x86/toolchain/arm-eabi-4.2.1/bin/arm-eabi-gdb.
May 25 06:36:51 <wmealing> i have a friend who is going to try porting systemtap to android, that's going to be .. interesting
May 25 06:37:18 <lucius> i have read that, but i don't quiet follow
May 25 06:37:22 <lucius> the steps
May 25 06:37:48 <lucius> you said i can't run gdbserver
May 25 06:37:58 <lucius> but the first step is to push gdbserver
May 25 06:38:09 <wmealing> that was my mistake
May 25 06:38:20 <wmealing> i assumed that webkit was mulithreaded
May 25 06:40:01 <lucius> it is multi thread
May 25 06:40:45 <lucius> so please tell me what are the steps i need to do ?
May 25 06:41:44 <wmealing> apparently, multi threaded apps now seem to be supported, as long as you run the gdb client from the android tree.
May 25 06:41:55 <wmealing> lucius, i assume you have the emulator running and booted ?
May 25 06:42:00 <lucius> yes
May 25 06:42:10 <wmealing> ok
May 25 06:42:13 <lucius> i run and i see the desktop
May 25 06:42:17 <wmealing> have you compiled the toolchain yet ?
May 25 06:42:24 <lucius> i did a 'make -j4'
May 25 06:42:38 <wmealing> mk ?
May 25 06:42:58 <lucius> and then run 'out/host/darwin-x86/bin/emulator'
May 25 06:43:05 <lucius> i am doing this on MacOS
May 25 06:43:21 <lucius> and i get the source of cupcake
May 25 06:47:00 <wmealing> oh
May 25 06:47:07 <wmealing> i have no idea on osx
May 25 06:47:21 <lucius> i assume it is similar on linux
May 25 06:48:30 <wmealing> then continue to follow the steps http://honeypod.blogspot.com/2008/01/debug-native-application-for-android.html
May 25 06:48:58 <wmealing> you may need to compile your code specifically.
May 25 06:51:22 <lucius> do i still need to download gdbserver and push that to /data/tmp?
May 25 06:51:57 <wmealing> yes.
May 25 06:53:13 <lucius> and what is the meaning of 'redir add tcp:1234:1234'? why i need to do a tcp redirect to 1234?
May 25 06:53:32 <wmealing> so gdb client can talk to it
May 25 06:53:38 <wmealing> since you run "gdb" locally on your machine
May 25 06:53:42 <wmealing> and the "server" on thephone
May 25 06:54:09 <lucius> why can't the gdb client talks directory to 5554?
May 25 06:54:24 <lucius> it said
May 25 06:54:24 <lucius> $ telnet localhost 5554
May 25 06:54:25 <lucius>  redir add tcp:1234:1234
May 25 06:54:25 <lucius>  exit
May 25 06:54:38 <lucius> why i need to redirect 5554 to 1234?
May 25 06:54:53 <romainguy> you redirect the port 1234 of your machine
May 25 06:55:00 <romainguy> to the port 1234 of the emulator
May 25 06:55:18 <romainguy> you're not redirecting 5554 to 1234
May 25 06:56:40 <lucius> thx.
May 25 06:56:59 <lucius> what is the meaning of this step:
May 25 06:57:00 <lucius> # ./gdbserver 10.0.2.2:1234 hello1
May 25 06:57:06 <lucius> why 10.0.2.2?
May 25 06:58:00 <lucius> and in step 5, telnet localhost 5554, what is port 5554?
May 25 06:58:12 <romainguy> it's the port you use to talk with the emulator
May 25 06:58:20 <romainguy> it's a special server used to send commands to the emulator itself
May 25 06:58:24 <romainguy> (but not the OS it hosts)
May 25 07:00:45 <lucius> in step 9, it said ' (gdb) target remote localhost:1234'
May 25 07:01:06 <lucius> so can i use any gdb client? e.g. the one comes with IDE?
May 25 07:01:18 <lucius> e.g. XCode's gdb client?
May 25 07:01:37 <wmealing> doubt it
May 25 07:01:52 <wmealing> by all means try though
May 25 07:07:39 <wmealing> romainguy, i have a question.. is it possible in 1.5 to "plug" into the top level setings program ?
May 25 07:07:46 <romainguy> no idea
May 25 07:07:50 <romainguy> I think it's possible
May 25 07:08:05 <lucius> may i ask how is the experience in debugging native code? is that fast?
May 25 07:08:12 <wmealing> no, debugging is slow
May 25 07:08:13 <wmealing> always slow
May 25 07:08:30 <romainguy> as is compiling the platform
May 25 07:08:31 <lucius> i mean responsive with the debugger?
May 25 07:08:35 * romainguy watches compiler logs...
May 25 07:08:53 <romainguy> lucius: Java debugging is responsive to native debugging should not be worse
May 25 07:09:00 <lucius> like debugging java code on eclipse
May 25 07:09:14 <lucius> k
May 25 07:09:18 <lucius> thx
May 25 07:16:52 <jsharkey> romainguy: hm?
May 25 07:17:06 <romainguy> jsharkey: I read about a bug with widgets
May 25 07:17:09 <romainguy> but I can't remember where
May 25 07:17:36 <romainguy> it seems like if you rotate the screen while adding/configuring a widget, it gets in a bad state
May 25 07:17:37 <jsharkey> the dev example doesnt stopSelf
May 25 07:18:09 <jsharkey> ah yes, if the configuration isnt fullscreen, meaning launcher responds to the orientation change under your activity
May 25 07:20:18 <romainguy_> jsharkey: shouldn't we handle that case? :)
May 25 07:20:41 <jsharkey> yes :)
May 25 07:20:49 <jsharkey> file a bug?
May 25 07:21:08 <romainguy_> you file a bug :0
May 25 07:21:22 <jsharkey> btw i think i finally get the purpose of fixits  ;)
May 25 07:21:34 <romainguy_> really?
May 25 07:21:35 <romainguy_> I still don't
May 25 07:21:45 <romainguy_> feels like it's what we're supposed to do every day :)
May 25 07:22:01 <jsharkey> its to clean out all these little bugs that have slowly piled up
May 25 07:22:32 <romainguy> I say that's what the community's for :p
May 25 07:22:38 <jsharkey> jham taught me to cope with my buglist by just ignoring it  :/
May 25 07:22:43 <romainguy_> yep
May 25 07:22:45 <romainguy_> that's the spirit
May 25 07:23:01 <romainguy_> I use Mike as my expample :))
May 25 07:23:06 <jsharkey> LOL
May 25 07:23:20 <jsharkey> i dont think ive ever actually seen him comment on bugs
May 25 07:23:26 <jsharkey> dont blame him tho
May 25 07:23:33 <romainguy> that's because you joined too late :)
May 25 07:23:49 <jsharkey> "management mode"
May 25 07:23:54 <romainguy> yes
May 25 07:24:30 <romainguy_> wtf
May 25 07:24:36 <jsharkey> O.o
May 25 07:24:36 <romainguy_> build doesn't boot @!#
May 25 07:24:49 <jsharkey> welcome to master?  :P
May 25 07:24:52 <romainguy_> donut
May 25 07:24:55 <jsharkey> ugh
May 25 07:25:13 <romainguy_> looks like mathias broke pixelflinger/surfaceflinger
May 25 07:25:38 <jsharkey> we need rockflinger
May 25 07:26:02 <wmealing> <jsharkey> jham taught me to cope with my buglist by just ignoring it  :/ <-- genius.
May 25 07:26:31 <jsharkey> wmealing: i feel bad about it
May 25 07:27:59 <romainguy_> jsharkey: it'll pass
May 25 07:28:12 <wmealing> jsharkey: you should see my queue.
May 25 07:28:26 <wmealing> « ‹  --   Displaying 50 rows (out of 937) 1 - 50   [1 2 3 4 5 6 7 8 9]   ++ [all]  › »
May 25 07:28:41 <jsharkey> wmealing: yikes, what project?
May 25 07:29:00 <wmealing> Linux - base os.
May 25 07:29:13 <jsharkey> soooo umm kernet?
May 25 07:29:15 <jsharkey> *kernel
May 25 07:29:20 <wmealing> kernel, userspace,
May 25 07:29:30 <wmealing> a lot of the basic utils, like bash etc
May 25 07:30:04 <wmealing> i group bugs, by code area.
May 25 07:30:14 <wmealing> fix the bugs that affect the most people
May 25 07:30:24 <wmealing> work "like bugs" together.
May 25 07:30:33 <romainguy_> wtf
May 25 07:30:37 <romainguy_> I reboot the device and it works
May 25 07:30:43 <romainguy_> even though it couldn't find .so libraries
May 25 07:30:48 <wmealing> romainguy, they dont call it the magic for nothing !
May 25 07:30:56 <romainguy_> wmealing: it's not a magic :p
May 25 07:30:58 <romainguy_> it's a dream
May 25 07:31:08 <romainguy_> anyway
May 25 07:31:10 <wmealing> hah
May 25 07:31:18 <romainguy_> I can finally start the task I set out to do 6 hours ago :)
May 25 07:37:19 <wmealing> jsharkey, do you know if you can "plug" into the main system preferences list ?
May 25 07:37:37 <wmealing> ie, third party program
May 25 07:57:02 <chihau> Who know a good tutorial for develop of widgets??
May 25 08:06:09 <ewon> \o/
May 25 08:16:05 <uscheller> I want to show a webview with (nearly) the same look on the iPhone and Android. My problem is that on Android it is 3 times bigger (zoomed in). In my html code its the "font-size: 3em;" tag that looks good on the iPhone and with 1em it looks fine on Android. Any guess what I should change except creating an "if browser==xy" statement=
May 25 08:16:05 <uscheller> ?
May 25 08:45:56 <rzr> hi
May 25 08:46:57 <FormicAcid> lo
May 25 11:04:24 <Gaz> hey can anyone help i upgraded to 1.5 and now i cant get eclipse to make R.java
May 25 11:08:31 <Gaz> oh finally it just worked hmm
May 25 11:09:29 <FormicAcid> yeah you need to specify the target
May 25 11:09:38 <Gaz> it worked for one file but not another hmm
May 25 11:09:45 <Gaz> yeh i clicked apply it fixed one file
May 25 11:09:48 <FormicAcid> but playing from 1.5 to 1.1 make some wierd effect so stick to 1.5 ;)
May 25 11:10:11 <Gaz> still complaning about r even tho it is there now in gen files
May 25 11:11:22 <Gaz> this R.java thing has been infuriatign from the start
May 25 11:11:35 <Gaz> thought id seen the last of it
May 25 11:12:59 <Gaz> ah it was impirting android.R which messed it up
May 25 11:17:50 <FormicAcid> that's the price for magic thingnies :P
May 25 11:28:39 <cesar9> hey, someone here knows how to save data, so they still exist after a restart of the application ?
May 25 11:34:06 <sammyF> morning everybody
May 25 11:40:48 <Gaz> anyone alive
May 25 11:42:33 <sammyF> define "alive"?
May 25 11:43:06 <sammyF> 4 and a half hours sleep is no premise for living somehow
May 25 11:47:30 <Gaz> hehe
May 25 11:50:25 <sammyF> does the orientation sensor need calibration somehow? or, asked differently, are the values the orientation sensor returns location dependant?
May 25 11:53:50 <FormicAcid> cesar9 check Preference in the API
May 25 12:06:49 <cesar9> thanks
May 25 12:07:55 <imran514> hey Guys..!!
May 25 12:08:28 <imran514> did any one worked wit customized Toast..??
May 25 12:09:57 <imran514> ny one der..??
May 25 12:11:51 <imran514> :s
May 25 12:30:11 <mmmulani> how do you extend an imageview to allow an animated gif? (can't seem to find the api demo on it)
May 25 12:36:28 <imran514> if i write customised Toast..its not showing any Border....see this for ref,,,,,http://up.mibbit.com/up/o2RuRhld.png
May 25 12:37:12 <imran514> how can i get border for the Toast.... help me out guys...
May 25 12:37:31 <imran514> :)
May 25 13:25:02 <sammyF> anybody ever worked with getRotationMatrix?
May 25 13:25:09 <sammyF> from the SensorManager
May 25 13:54:27 <sammyF> anybody knows if there is any way to know whether the device is standing on its head or not (Z Orientation axis)?
May 25 13:54:42 <sammyF> the value is the same for up and down :/
May 25 13:55:36 <wmealing_> sammyF, dont know, but i know that skymap can tell
May 25 13:57:13 <severb> I'm using a Handler to schedule some background job to take place from time to time (downloading a pic from web) but while the downloading the pic the UI is not responding, any ideas on that?
May 25 13:57:55 <marklar> severb: you should put any long running operations on a background thread
May 25 13:58:36 <ILEoo> severb: there was some nice example on that in http://android-developers.blogspot.com/
May 25 13:58:40 <severb> how can I do that? the runnable called by the Handler must create a new thread?
May 25 13:58:52 <ILEoo> severb: on Painless threading topic
May 25 13:59:02 <marklar> severb: off the top of my head Thread t = new Thread(<your handler>);
May 25 13:59:04 <severb> ILEoo i'll take a look
May 25 13:59:24 <sammyF> wmealing: true
May 25 13:59:28 <marklar> erm, rather runnable not handler
May 25 13:59:33 <sammyF> wmealing: I wonder how it does that :/
May 25 14:01:18 <sammyF> ah! I think I got it. thanks wmealing
May 25 14:07:06 <wmealing_> sammyF, glad.. to help although I didnt do too much
May 25 14:07:11 <wmealing_> sammyF, whats the trick ?
May 25 14:07:28 <sammyF> wmealing: check the sign of the Y axis
May 25 14:07:43 <severb> man, I just don't get it! If I create a Handler from a Service to run some background jobs why does it block the UI?
May 25 14:07:50 <sammyF> if it's negative, the device is help upright, if it's positive the device is held downward
May 25 14:07:58 <sammyF> aparently
May 25 14:08:01 <wmealing_> ah
May 25 14:08:20 <sammyF> wmealing: going to send my game to a friend to see if it works for him too ;)
May 25 14:08:45 <marklar> severb: its running on the UI thread, so since it takes a while it will block. Give me a minute and I can find you an example
May 25 14:08:54 <marklar> The basic idea though is that you want to run a runnable on a new thread
May 25 14:09:38 <severb> yes, I don't need to change the UI from that background job
May 25 14:10:03 <severb> i just want it to run in a separate thread so it doesn't block the UI
May 25 14:10:50 <marklar> Do you have a Runnable that is executing the task?
May 25 14:10:55 <severb> yes
May 25 14:11:21 <marklar> Then just create a new thread with that. Thread t = new Thread(<your runnable>); t.start()
May 25 14:11:28 <severb> and on the end of run method it reschedule itself: mHandler.postDelayed(this, nextInterval());
May 25 14:12:05 <marklar> hmm, well it may be tricky with rescheduling itself, but what I just wrote should have it execute once
May 25 14:12:53 <severb> I've tried to create the Handler in a new thread so it will bind to that thread and run my background job on a separate thread but with no success
May 25 14:13:31 <marklar> severb: Could you post the code?
May 25 14:13:54 <severb> yes, why not it's a school project after all
May 25 14:14:04 <severb> let me upload it somewhere
May 25 14:15:44 <marklar> man I wish I had gotten to work on Android in school
May 25 14:16:27 <severb> well, I don't enjoy it so much I prefer hacking on python code
May 25 14:16:39 <marklar> ah, yeah java can be annoying
May 25 14:18:15 <severb> here it is the Service class http://paste.pocoo.org/show/119015/
May 25 14:19:08 <severb> this service gets started from an activity or when the phone starts, it changes the wallpaper of the phone with random photos from flickr
May 25 14:19:17 <marklar> k
May 25 14:24:30 <marklar> I'll be honest, I'm not sure why you're UI would hang with this. Are you using an activity to query the service for the new image?
May 25 14:25:14 <severb> i'm using this http://code.google.com/p/apps-for-android/source/browse/trunk/Photostream/src/com/google/android/photostream/Flickr.java
May 25 14:25:55 <marklar> Since you are doing it in a service, I'm guessing an activity is trying to query the service while the service is downloading...
May 25 14:26:49 <marklar> What I would do is get rid of the handler, create a new thread with the runnable, and just make the runnable loop with a call to Thread.sleep(nextInterval())
May 25 14:27:10 <severb> the only thing in my activity that touch this Intent i = new Intent(this, BgChanger.class); startService(i);
May 25 14:28:36 <severb> isn't the service getting it's own thread if I start it with startService ?
May 25 14:29:19 <marklar> afaik yes, thats why I'm not sure why it would hang :)
May 25 14:29:59 <marklar> Is the whole phones UI stopping or just the app?
May 25 14:30:03 <severb> yeah... I know... this android process/theread thing is killing me
May 25 14:30:09 <severb> just the app
May 25 14:30:18 <severb> if i'm not in the app everything runs just fine
May 25 14:30:28 <severb> the wallpapers are changing
May 25 14:31:12 <marklar> severb: huh, sorry I don't know what to tell you, beyond my knowledge
May 25 14:31:36 <severb> well thanks anyway, maybe someone else is willing to take a look
May 25 14:31:46 <marklar> np, hopefully you can figure it out, its a nice idea
May 25 14:33:50 <severb> If I try to change the UI while the pic is downloading I get a lot of messages like this
May 25 14:33:52 <severb> W/WindowManager(   49): No window to dispatch pointer action 0
May 25 14:33:52 <severb> W/WindowManager(   49): No window to dispatch pointer action 1
May 25 14:40:38 <mmmulani> hmmmm
May 25 14:41:03 <mmmulani> can you make Messaging default to "sms_body" instead of Intent.EXTRA_TEXT when you send an intent to it?
May 25 14:43:55 <severb> is there any other irc channel like this where I can ask about android dev?
May 25 14:45:07 <marklar> severb: there is one on EFnet iirc, this one is much more populated though. I'd try again a little later, or try on the googlegroup, you'll get many more people looking at it there.
May 25 14:47:06 <severb> great, thanks
May 25 15:15:03 <severb> marklar: I've fixed it
May 25 15:15:34 <marklar> severb: nice! what was the problem?
May 25 15:15:37 <severb> looks like the service is running in the same thread with the UI
May 25 15:15:49 <marklar> huh strange
May 25 15:15:53 <marklar> how did you fix that?
May 25 15:16:30 <severb> so I spawned a new thread that will download the pic and change the background inside the run() method of backgroundChanger
May 25 15:16:38 <severb> it was an easy fix
May 25 15:16:48 <marklar> nice :)
May 25 15:16:56 <marklar> looks like I need to read up on services
May 25 15:17:42 <severb> tdaj
May 25 15:17:45 <severb> yeah
May 25 15:27:22 <severb> uh, How to stop a service from an Activity?
May 25 16:17:02 <doc_savage> I read a few days ago - performance coding on mobile devices, or something similar, it was saying that floats/doubles have a large performance hit compared to int's, is it a big enough hit to require breaking long/lat data into 2 ints each?
May 25 16:17:40 <wmealing_> doc_savage, i'd say if it becomes a problem, do it.
May 25 16:17:46 <wmealing_> otherwise, dont bother.
May 25 16:17:56 <wmealing_> maybe if you are doing a bunch of math
May 25 16:18:27 <doc_savage> wmealing: ok, I'm only just setting out coding, so figured I should do it from the start, but it's literally to store/set push pins on a mapview, so probably not that intensive, but there could be a lot to add
May 25 16:18:46 <doc_savage> (depending on the zoom level of the mapview)
May 25 16:18:59 <wmealing_> yep
May 25 16:19:08 <wmealing_> otherwise you can do normal ints
May 25 16:19:24 <wmealing_> unless you are doing math on them, i'd keep it simple.
May 25 16:19:45 <wmealing_> since you're going to need the space anyway
May 25 16:19:47 <wmealing_> two ints
May 25 16:19:51 <wmealing_> <int1>.<int2>
May 25 16:20:04 <wmealing_> no matter what happens, you'll be spending the time on the object
May 25 16:20:18 <doc_savage> ok cool, would using "byte" be better? as less memory usage? (not sure on the range of long/lat - I'd need to check that)
May 25 16:20:45 <wmealing_> can it store what you need in a byte ?
May 25 16:20:47 <doc_savage> but if bytes can fit long/lat ranges in, is it worth using them instead of ints?
May 25 16:20:57 <doc_savage> I'm not sure, I'll ahve to check, but if it does, go for a byte?
May 25 16:21:27 <wmealing_> doc_savage, if the byte fits, wear it.
May 25 16:21:52 <wmealing_> boot.
May 25 16:21:54 <wmealing_> nevermind
May 25 16:21:59 <doc_savage> ok cool :D thanks wmealing
May 25 16:23:42 <marklar> doc_savage: in general, I wouldn't ever do premature performance optimizations... unless its actually causing a problem you don't need to mess with it.
May 25 16:24:11 <wmealing_> doc_savage, http://stackoverflow.com/questions/229886/size-of-a-byte-in-memory-java
May 25 16:24:20 <doc_savage> marklar: so you'd go with a double, if it's taking forever to load stuff, try switching to a ints/bytes?
May 25 16:24:36 <wmealing_> doc_savage, only optimize when needed.
May 25 16:24:49 <wmealing_> "premature optimization is the root of all evil"
May 25 16:24:49 <marklar> doc_savage: yup
May 25 16:24:51 <wmealing_> so the saying goes
May 25 16:25:13 <marklar> doc_savage: I always do it the easy way first, and if that doesn't work do it the hard way :)
May 25 16:25:20 <doc_savage> lol ok guys, thanks for the tips, I'm new to java and (serious) mobile dev, so it's much appreciated
May 25 16:25:31 <marklar> np
May 25 16:25:48 <doc_savage> right, doubles it is, that'll help a lot anyway, lowering the confusion already caused by a new environment :)
May 25 16:25:59 <wmealing_> doc_savage, me too.
May 25 16:26:02 <doc_savage> one last question, double or float?
May 25 16:26:27 <wmealing_> that question should be answered by the range of values you are storing.
May 25 16:26:33 * doc_savage looks around for his java course books
May 25 16:26:56 <marklar> doc_savage: I would use whatever the platform uses for storing the data, I think its double in this case
May 25 16:28:04 <doc_savage> marklar: ok cool, wmealing: I think either will hold what I need, I think it's basically 0.00-360.00 for long/lat, although I've only seen up to 165.00 being used
May 25 16:29:04 <doc_savage> thanks again guys
May 25 16:56:43 <svm_invictvs> Hiya.
May 25 17:01:09 <pawbie> Could someone give me an example of an application that registers itself as a handler for a file extension?  For example, if I'm in ASTRO or similar and click a file with extension .paw, i would like my app to launch.
May 25 17:02:42 <svm_invictvs> So I'm trapping the "Back" button press and having it show a confirm menu in some cases.  There are certain times I don't want the activity destroyed when the user presses "back."  The problem is that, it appears a new activity is instantiated when I come back into the program from a "Home" button press, and that just makes the state of my application barf.  Is there a proper way of trapping the "back" button press that then c
May 25 17:03:23 * wmealing_ is here, but doesnt know the answer to either
May 25 17:04:27 * sammyF is here, and is actually interested in an answer to svm_invictvs question
May 25 17:04:40 <pawbie> svm_invictvs: Using super.onCreate(savedInstanceState) in your onCreate() ?
May 25 17:04:40 <svm_invictvs> I'm gonna play with it.
May 25 17:04:55 <svm_invictvs> You'd get an exception if you don't call super.
May 25 17:05:42 <sammyF> sigh .. need to boot windows :(
May 25 17:05:45 <sammyF> bbl
May 25 17:05:50 <svm_invictvs> sammyF: Death march?
May 25 17:05:57 <sammyF> yeah ;)
May 25 17:06:18 <sammyF> skype stopped working with my webcam, so I need to actually boot into windows to have a decent web conf
May 25 17:09:38 <pawbie> hm
May 25 17:10:36 <pawbie> Astro shows it's intent launch for "content://astro/sdcard/testfile.paw"..  My manifest has data android:mimeType="text/plain", host="*" scheme="content" pathPattern=".*\\.obj"
May 25 17:10:44 <pawbie> I dunno what I could be missing.
May 25 17:12:21 <keny> hello
May 25 17:19:35 <mmmulani> anyone know where I can find some mp4 files that properly stream to the android?
May 25 17:23:24 <pawbie> Oh, it works!
May 25 17:23:27 <pawbie> wtf did I do...
May 25 17:25:25 <ttuttle> Hey.
May 25 17:25:41 <ttuttle> I'm making an app that (among other things) allows users to upload database entries to a website.
May 25 17:26:23 <ttuttle> Is there a way to rig an activity (the add activity) so that it cannot be entered backwards from another activity (the upload activity)?
May 25 17:38:46 <TD_> Rexxars: is it really based on ThreadExecutor then?
May 25 17:40:28 <TD_> Rexxars: you can use a semaphore with 10 permits to solve that in a non-racy way
May 25 17:40:45 <TD_> then file a bug against romainguy to not use ThreadPoolExecutor in the AsyncTask class :)
May 25 17:49:25 <NutMonkey> I have a ListView with a SimpleCursorAdapter, how do I get the ListView position of the row with a given db _id?
May 25 18:13:19 <jasta> NutMonkey: hang on...
May 25 18:14:21 <jasta> NutMonkey: are you trying to access the View for that particular _id or are you just trying to figure out where it is in the list?
May 25 18:16:18 <jasta> also, what reason do you need this information?
May 25 18:46:07 <keny> hi
May 25 18:46:33 <svm_invictvs> Another question...
May 25 18:46:42 <svm_invictvs> I can't connect an actual device unless I run adb as root.
May 25 18:47:06 <svm_invictvs> What permissions do I have to set in my udev conf files to get that working.  I see them listed for Ubuntu, but that evidently doesn't work for gentoo.
May 25 18:47:46 <jasta> svm_invictvs: is this device a G1 or a Magic?
May 25 18:48:17 <jasta> also, the instructions for ubuntu differ between ubuntu versions, specifically because of different versions of udeb
May 25 18:48:21 <jasta> udev*
May 25 18:49:15 <jasta> in ubuntu 9.04, because of an upgrade to udev, you need to move the file up to 51-android.rules (from 50)
May 25 18:49:29 <svm_invictvs> jasta: g1
May 25 18:49:30 <mmmulani> hmm, how would you save a drawable into a parcel?
May 25 18:54:41 <keny> anyone can give me a few pointers on how to implement the equivalent of marker.openInfoWindow (from the javascript maps api) with the android api?
May 25 18:54:58 <keny> (hm, not referring to 0xdeadbabe pointers :D )
May 25 18:56:08 <keny> the hello, views demos stop right before doing something similar, they just use a drawable for displaying markers, but don't know how the maps application does this or if this is documented anywhere.
May 25 19:17:45 <svm_invictvs> How do I get events for buttons on my layout?
May 25 19:18:40 <marklar> svm_invictvs: I'm not sure what you mean, could you rephrase that?
May 25 19:18:54 <svm_invictvs> So I create a layout in XML
May 25 19:19:07 <svm_invictvs> I set it it with setContentView(R.layout.foo);
May 25 19:19:10 <svm_invictvs> And it shows up
May 25 19:19:26 <svm_invictvs> BUt how do I connect it to any code?  What do I override in my activity to receive those events?
May 25 19:19:47 <marklar> You need to use findViewById (using the ID you gave the view in your XML) to get a reference to the view
May 25 19:19:58 <svm_invictvs> ah
May 25 19:20:10 <svm_invictvs> Which I didn't set.
May 25 19:20:10 <marklar> then you can call setOnClickListener (or whatever you are trying to do) on it
May 25 19:20:36 <marklar> svm_invictvs: its an easy fix :)
May 25 19:21:10 <svm_invictvs> marklar: Yeah, most of my app has it's own UI, not using the Android ui stuff.
May 25 19:22:18 <marklar> svm_invictvs: I would hope you're app has its own UI ;)
May 25 19:22:35 <svm_invictvs> marklar: As in I manually draw the UI myself with a Canvas.
May 25 19:22:44 <marklar> oooh ok lol
May 25 19:23:27 <marklar> That sounds interesting, is there any chance the code is available?
May 25 19:23:49 <svm_invictvs> marklar: Yeah.... at some point.  This app is a port from MIDP
May 25 19:23:59 <marklar> svm_invictvs: k, look forward to seeing it
May 25 19:24:18 <svm_invictvs> marklar: you can see the screen shots...
May 25 19:25:32 <marklar> svm_invictvs: oh, I'm more interested in seeing how you are drawing the UI on a canvas :)
May 25 19:26:28 <svm_invictvs> marklar: I've written 3 UI toolkits in my time.  It's not fun.
May 25 19:26:40 <marklar> svm_invictvs: I've written none, and I believe you
May 25 19:27:17 <svm_invictvs> marklar: I wrote one in C++ for the Xbox360, then I ported that to Wii and added Lua support, and i wrote one in J2ME, then ported it over to Android.
May 25 19:27:35 <marklar> nice
May 25 19:28:05 <svm_invictvs> marklar: And I wrote some patches for SWT at my first job but they wouldn't let me submit them to the project because my first boss was super paranoid about Open Source Software.  Also, he was a douchebag.
May 25 19:28:29 <marklar> svm_invictvs: ugh, thats the situation I'm at right now :(
May 25 19:29:06 <svm_invictvs> marklar: Is there a breakdown somewhere of all the XML elements for the UI stuff in Android?
May 25 19:29:33 <marklar> not that I know of... I just spent lots of time googling
May 25 19:30:00 <marklar> I would guess its somewhere though
May 25 19:38:57 <foo> anyone use sipdroid/familiar with it?
May 25 19:42:54 <Mmjack> How many threads can a applcation run at once without having a massive detrement on the devices battery?
May 25 19:44:57 <_Auron_> I think it depends moreso on what the threads are actually doing
May 25 19:45:15 <svm_invictvs> Does setContentView take effect immediately?
May 25 19:46:23 <Mmjack> Blocking and sending messages over a internet connection.
May 25 19:46:34 <Mmjack> Basically not much
May 25 19:57:34 <mmmulani> is the Activity documentation accurate? it seems as though my onCreate gets called everytime the orientation changes
May 25 19:59:54 <doc_savage> mmmulani: my understanding is that on an orientation change, the activity is completely killed and recreated, so you need to use onSaveInstanceState() etc. however I've noticed that EditTexts keep their values through an orientation change, I can't explain that
May 25 20:00:18 <svm_invictvs> Mmjack: how many threads are you running?
May 25 20:01:07 <svm_invictvs> Sounds like TPC...
May 25 20:01:08 <svm_invictvs> :(
May 25 20:17:28 <romainguy> doc_savage: default widgets who have an id save their states automatically
May 25 20:20:27 <mmmulani> romainguy: do orientation changes shut down the activity?
May 25 20:20:39 <doc_savage> romainguy: ah I see, that explains it, a webview is a "view", rather than a widget? (I had to set the webview to save it's state manually)
May 25 20:22:36 <romainguy_> widget == view
May 25 20:25:07 <doc_savage> romainguy: ah ok, things are getting clearer and clearer everyday :) thanks for the info
May 25 20:28:35 <mmmulani> hmmmm
May 25 20:29:11 <mmmulani> what ScaleType scales so that the width fills the parent and expands bounds so that height isn't cropped?
May 25 20:29:41 <romainguy> none
May 25 20:29:47 <romainguy> you want adjustViewBounds
May 25 20:30:18 <mmmulani> oh, just setAdjustViewBounds(true)?
May 25 20:32:20 <mmmulani> wow, that actually is exactly what I wanted
May 25 20:32:21 <mmmulani> thanks
May 25 20:36:19 <Leftmost> Is anyone aware of a SyncML implementation other than android-client?
May 25 20:37:15 <AakashPatel> Leftmost: uh..i saw one on wikipediea
May 25 20:37:26 <AakashPatel> look up syncml on wikipeida and it gives you a list of clients
May 25 20:37:43 <Rexxars> is there a "prefered" way to cache application data (such as downloaded and parsed XML data) in android? I've got a simple hashmap that I'd like to store, but I want to avoid writing/parsing XML or using a database..
May 25 20:38:01 <AakashPatel> Preferences?
May 25 20:38:06 <AakashPatel> ...maybe?
May 25 20:38:44 <Rexxars> can you store complex types such as HashMaps in preferences?
May 25 20:39:14 <AakashPatel> Hm.
May 25 20:39:24 <Leftmost> Hmm. It mentions Voxmobili, but that looks to be proprietary and very possibly non-free.
May 25 20:39:34 <AakashPatel> http://dev.android.com/guide/topics/data/data-storage.html
May 25 20:41:18 <wimbet> newb question, can a widget have different clickable zones? like one to expand widget and one to launch webview?
May 25 20:41:37 <AakashPatel> wimbet: i belive so
May 25 20:41:42 <AakashPatel> ive seen it done
May 25 20:41:51 <AakashPatel> look at the tech buzz widget
May 25 20:41:53 <AakashPatel> in the market
May 25 20:41:54 <wimbet> you know an example widget?
May 25 20:41:58 <wimbet> thanks
May 25 20:44:03 <wimbet> aakashpatel, super awesome.  thats exactly what i was talking about
May 25 20:44:17 <AakashPatel> :D
May 25 20:49:51 <Leftmost> I'm wondering how difficult it would be to cross-compile a couple of C libraries related to SyncML and wrap some Java around them. I have no idea how to even go about that, though.
May 25 20:54:38 <Ge0rG> it depends ;)
May 25 20:55:27 <Ge0rG> syncml is mostly XML, so it might be easier to use java to do the job. especially as you would have to hack sqlite to access the databases
May 25 20:56:39 <Leftmost> The communication protocol is what would probably cause difficulty.
May 25 20:56:44 <Ge0rG> OTOH, syncml is complex shit, so it might be better to port the C lib
May 25 20:57:46 <Leftmost> Port, rather than bind?
May 25 20:58:01 <Ge0rG> both ;)
May 25 20:58:50 <Leftmost> You've successfully confused me.:)
May 25 20:59:51 <Ge0rG> you have to port the C lib to bionic, or at least make a statically compiled arm binary of it. then you have to use JNI or some other black magic to use the code from java
May 25 21:02:43 <Leftmost> Hmm. And I suppose that I'd have to wrap up all of that in the client software itself to hand it out as an application. If that's even possible, really.
May 25 21:03:21 <Ge0rG> yes. and you'd have to provide different binaries when more android archs are supported by market
May 25 21:04:17 <Leftmost> Rewriting in Java would mean I'd have to try to keep up with upstream in a different language, which would be an absolute joy.
May 25 21:07:51 <Ge0rG> yeah :)
May 25 21:12:35 <zinx> Leftmost: ask jasta :P
May 25 21:39:29 <ttuttle> Hey.
May 25 21:39:48 <ttuttle> Is it possible for a custom view to start an activity and get a result?
May 25 21:40:01 <ttuttle> I've got access to a Context, but no way to get the result from the activity.
May 25 21:42:49 <sammyF> ttuttle:  isn't that done through onActivityResult?
May 25 21:44:51 <sammyF> ttuttle: you create a new intent in your activity (the one that has been created), use Intet.putExtra for example to store your results and then setResult
May 25 21:45:04 <sammyF> ttuttle: I might be wrong of course
May 25 21:50:22 <hunterp> I have the most simple activity, but its causing my emulator to hang: http://pastebin.com/m56c9250d
May 25 21:55:10 <hunterp> nevermind, needed to decalre in manifest
May 25 22:16:14 <ttuttle> sammyF: I can do that, but I can't catch the onActivityResult, because I'm writing a View, not an Activity.
May 25 22:49:49 <svm_invictvs> I'm trying to add a blurred image background to the layout.  Is that possible?
May 25 23:20:09 <Moons> hello everyone
May 25 23:20:36 <hunterp> wonder why locMgr.getProvider(LocationManager.NETWORK_PROVIDER).toString()  returns the DummyProvider
May 25 23:20:40 <Moons> I might need some help with FileDescriptors in Android, anyone can help? :)
May 25 23:20:49 <Moons> I just need to have a FileDescriptor to a raw resources in my APK ^^
May 25 23:35:56 <Moons> anyone in here?
May 25 23:42:14 <sammyF> Moons: kind of
May 25 23:42:27 <sammyF> Bank Holiday is probably not the best of time to ask questions
May 25 23:44:41 <jasta> Moons: you can achieve this with getResources().getAssets().openFd
May 25 23:44:56 <jasta> or openRaw whatever
May 25 23:45:01 <jasta> just look at AssetManager's javadoc
May 25 23:46:37 <Moons> i looked
May 25 23:47:04 <Moons> here is what i do
May 25 23:47:05 <Moons> esources.openRawResourceFd(R.raw.sound17).getFileDescriptor()
May 25 23:47:20 <Moons> but apparently it gives ma an FD to my apk, not to my single resources
May 25 23:49:14 <Leftmost> jasta, ping
May 25 23:49:21 <Moons> jasta, sammyF am I wrong?
May 25 23:49:58 <sammyF> don't ask me .. I'm struggling with the most basic concepts
May 25 23:50:18 <Moons> ok ^^
May 25 23:50:36 <Moons> i wonder why it is not working ...
May 26 00:33:35 <Johnster> Hi,
May 26 00:37:34 <sammyF> 'lo Johnster
May 26 02:03:13 <calamari> there was an android update in eclipse, and now the android jar is gone.. what should I do?
May 26 02:03:52 <sammyF> calamari: could it be that the update requires r2?
May 26 02:04:15 <calamari> ahh, so I need to install 1.5
May 26 02:04:45 <sammyF> well, basically you should be already using 1.5
May 26 02:04:58 <sammyF> you can write for 1.1 when you use the 1.5 sdk
May 26 02:05:10 <calamari> oh good
May 26 02:06:11 <calamari> thanks
May 26 02:06:16 <sammyF> np
