**** BEGIN LOGGING AT Wed Feb 18 02:59:57 2009
Feb 18 03:00:15 <DJTachyon> hehe
Feb 18 03:00:30 <joakime> Unless you are wanting to read the android source code, the xml based shapes will be static.
Feb 18 03:00:40 <joakime> once drawn, you are done.
Feb 18 03:00:55 <joakime> with View.onDraw(Canvas) you can use an invalidate loop to get basic updates.
Feb 18 03:00:56 <DJTachyon> i still haven't figured out service creation and aidl communcation ... i've learned everything about android and caught up on java from a 5 year hiatus in 3 weeks
Feb 18 03:01:14 <DJTachyon> hmm ..
Feb 18 03:01:23 <DJTachyon> alright looks like i will have to dig in deeper on this
Feb 18 03:01:43 <joakime> DJTachyon, lots of samples at anddev.org
Feb 18 03:01:51 <DJTachyon> all i want to do is create a fairly simple shape (a couple quadrangles) and change the colors at high speed based on sensor input
Feb 18 03:02:05 <DJTachyon> i figured out the sensor input, i just need to dig into drawing/rendering
Feb 18 03:02:33 <DJTachyon> joakime: did you see my silly LED/Sensor Demo app?
Feb 18 03:02:40 <DJTachyon> i figured that out today :P
Feb 18 03:02:41 <joakime> that was you!?
Feb 18 03:02:46 <DJTachyon> hehe
Feb 18 03:02:51 <DJTachyon> the RaveLED
Feb 18 03:02:52 <joakime> hmm. i should change my review ...
Feb 18 03:03:07 <DJTachyon> i post silly demos just to test feedback and demographics
Feb 18 03:03:12 <DJTachyon> lol uh oh
Feb 18 03:03:28 <DJTachyon> i got a TON of feedback from people on this stuff .. I found my demographic niche ..
Feb 18 03:03:48 <DJTachyon> did you rip into me? :P
Feb 18 03:05:16 <joakime> nah.
Feb 18 03:05:21 <joakime> 1 word i think.
Feb 18 03:05:25 <DJTachyon> heh
Feb 18 03:05:27 <joakime> my app -> http://www.cyrket.com/package/com.iversecomics.comic.viewer.hexed.one
Feb 18 03:05:40 <DJTachyon> hehe sweet
Feb 18 03:05:48 <DJTachyon> did you see that app from flygirl today?
Feb 18 03:05:56 <DJTachyon> god .. talk about demographic targeting
Feb 18 03:06:28 <DJTachyon> has urban/graffiti backgrounds .. you input a phrase and it turns it into ebonics for you
Feb 18 03:06:29 <DJTachyon> ugh
Feb 18 03:06:33 <DJTachyon> anyway
Feb 18 03:06:37 <DJTachyon> ill dig into this tomorrow
Feb 18 03:06:40 <DJTachyon> thanks for the input
Feb 18 03:09:37 <donpdonp> joakime: wow. impressively consistent reviews
Feb 18 03:09:50 <joakime> donpdonp, thanks.
Feb 18 03:10:03 <joakime> working on a bunch of bug fixes and improvements based on the reviews.
Feb 18 03:10:17 <joakime> once the paid apps start showing up, there will be more.
Feb 18 03:23:14 <donpdonp> in my PreferenceActivity, i do onResume() { local_preference.setSummary(preference_value) }, yet when the preference is changed via the dialog box, the activity's onResume is not called again so the summary is out of date. how to fix?
Feb 18 03:27:05 <mfisch> I'm going to submit a patch to the Eclipse project to accept the spelling of "Android"
Feb 18 03:42:40 <mfisch> How do I remove my app from the emulator?
Feb 18 03:43:02 <mfisch> My app uses a DB and its upset about the DB versions changing
Feb 18 03:45:38 <donpdonp> mfisch: adb unistall your.package.name
Feb 18 03:45:42 <donpdonp> uninstall, even.
Feb 18 03:46:05 <mfisch> donpdonp: is that doable in eclipse or just command line
Feb 18 03:49:02 <jasta> mfisch: you can design your code to gracefully upgrade database tables as well.  this way, your users will not need to uninstall/reinstall your app.
Feb 18 03:49:10 <jasta> and will not need to repopulate the database again
Feb 18 03:49:15 <mfisch> jasta: I will do that, yes
Feb 18 03:49:25 <jasta> see DatabaseOpenHelper or something like that
Feb 18 03:49:29 <mfisch> jasta: I'm just starting out by messing with the notepad app
Feb 18 03:59:24 <donpdonp> um. two people just purchased my $1 app.
Feb 18 03:59:42 <donpdonp> i think paid apps are online in some capacity
Feb 18 04:00:22 <KNY> donpdonp, beta testers, last I heard
Feb 18 04:00:34 <donpdonp> ah
Feb 18 04:00:53 <donpdonp> that explains why i cant see the app in the market on the phone
Feb 18 04:01:01 <KNY> I need to make another app (which I can sell)
Feb 18 04:09:01 <g1bb> interns
Feb 18 04:09:03 <g1bb> to be exact
Feb 18 04:09:13 <g1bb> I googled the guy that bought mine :P
Feb 18 04:09:24 <g1bb> i'm creepy
Feb 18 04:19:52 * donpdonp shivers
Feb 18 05:06:11 <ravv> You can actually see who buys your applications?
Feb 18 05:07:16 <g1bb> yeah
Feb 18 05:07:22 <g1bb> kinda scary actually - lots o details
Feb 18 05:28:57 <herriojr_> is there a way to set a ContentObserver that is active even while your program is closed?
Feb 18 05:29:16 <romainguy> what's the point if your program is not running?
Feb 18 05:31:09 <herriojr_> makes it easier to watch a database for changes, especially since if I didn't implement the database, I can't just watch the isDirty column to see if it has changed because I don't control when it is set and unset
Feb 18 05:32:36 <herriojr_> so if I know each time something changes, I can keep my own isDirty for each row
Feb 18 05:33:32 <herriojr_> well, let me think about it some more
Feb 18 05:34:59 <rsteckler> you can wake up to check the database...
Feb 18 05:35:16 <herriojr_> yes, I know that
Feb 18 05:35:53 <herriojr_> I wanted to know changes when they happen, but I guess running on a battery, that might not be a good thing
Feb 18 05:56:55 <herriojr_> do ContentProviders block processes in the same way SQL does?
Feb 18 05:59:44 <herriojr_> nevermind, found a doc on it
Feb 18 06:32:21 <herriojr_> Is imageView.setImageBitmap(null) not supposed to set a null Drawable for the view?  I know I can do imageView.setImageDrawable(null), but I wanted to see if this is known or on accident
Feb 18 06:36:27 <romainguy> it's expected
Feb 18 06:38:47 <herriojr_> kk
Feb 18 07:21:49 <anno^da_> I have tried to set onClick listeners in the adapter but romain told me that this is the wrong way and I should do it in the onListItemClick
Feb 18 07:22:16 <anno^da_> But I don't get how to differentiate the items that got clicked it the right way in my situation :)
Feb 18 07:22:51 <jasta> anno^da_: differentiate them with the adapter and the information provided by the onlistitemclick callback
Feb 18 07:23:26 <anno^da_> Should I add IDs to the rows ?
Feb 18 07:23:33 <jasta> i think its actually called onitemclicklistener tho
Feb 18 07:23:39 <anno^da_> in to each row
Feb 18 07:23:46 <anno^da_>  onListItemClick(ListView l, View v, int position, long id)
Feb 18 07:23:46 <jasta> that is not necessary
Feb 18 07:23:51 <jasta> you are given the position in the list as well.
Feb 18 07:24:05 <jasta> if you cant work out what your data is given the position and the id, then your design needs work :)
Feb 18 07:24:39 <anno^da_> Hmm well. :)
Feb 18 07:26:39 <anno^da_> I have just reused the SeperatedList adapter but well that doesnt helpe me since I get for ID and POS the same value
Feb 18 07:27:56 <jasta> bbl
Feb 18 08:05:00 <herriojr_> How do I load images into a list sequentially without making the list slow down a bunch?  I was trying to do it in a handler, one by one, but it refreshes all the views at the end of each handleMessage
Feb 18 08:05:29 <herriojr_> which slows it down a bit
Feb 18 08:07:23 <herriojr_> the marketplace seems to have no issues with it
Feb 18 08:09:28 <herriojr_> so, it looks like the marketplace is using a image pool, but for me, it seems to be the handler slows it down a whole bunch
Feb 18 08:10:33 <herriojr_> I'm not using a pool yet, I wanted to make sure the loading isn't too slow in the first place
Feb 18 08:14:46 <herriojr_> what I'm doing is moving to the first item displayed in the list, starting a thread to load its images, once the thread finishes, it calls a handler in the main thread to load the images to the item then moves to the next item....this is very inefficient for some reason and scrolling is no longer smooth
Feb 18 08:21:07 <anno^da_> jasta: Got it working now. :)
Feb 18 12:59:22 <DJTachyon> ahh stupid reviewers :)
Feb 18 13:54:22 <lazerdye> Hi, I am trying to use the 'gallery' widget to scroll things horizontally, but text inside the widget is turning a dark color and hard to read.
Feb 18 15:37:34 <herriojr> lazerdye: when is it turning a dark color?
Feb 18 15:38:13 <lazerdye> herriojr: Hi, when the app first starts up the text is a dark color, when I drag the item left or right it changes to a lighter color and stays like that.
Feb 18 15:40:48 <herriojr> that's interesting, do you set the font text programatically?
Feb 18 15:40:57 <herriojr> or in the layout?
Feb 18 15:41:05 <herriojr> I mean text color
Feb 18 15:42:01 <herriojr> not font text
Feb 18 15:44:59 <herriojr> Hey, is there stuff in the SDK to help with minimizing GC for bitmaps (I'm sticking bitmaps in a list)
Feb 18 15:45:13 <herriojr> is=are
Feb 18 15:45:17 <herriojr> or whatever
Feb 18 15:45:19 <lazerdye> herriojr: I tried setting the text color manually, using color, textColorHighlight, textColorHint, and textColorLink, but the colors stay the same.
Feb 18 15:45:28 <lazerdye> It also turns dark when selected/clicked on.
Feb 18 15:45:51 <marklar> lazerdye: this is a total shot in the dark, but could it possibly be something like this: http://android-developers.blogspot.com/2009/01/why-is-my-list-black-android.html ?
Feb 18 15:46:05 <marklar> haven't used gallery myself
Feb 18 15:47:14 <lazerdye> marklar: thanks, I'll try some suggestions from that page.
Feb 18 15:47:25 <herriojr> lazerdye: I don't think it's the same issue
Feb 18 15:47:32 <herriojr> lazerdye: but that's just my opinion
Feb 18 15:47:39 <lazerdye> it may be related....
Feb 18 15:47:49 <marklar> yeah, I really don't know either, just wanted to throw it out there :)
Feb 18 15:48:57 <lazerdye> Yeah, cacheColorHint doesn't make a difference, either on the gallery or on the text.
Feb 18 15:48:57 <herriojr> are there tools to reuse bitmap memory
Feb 18 15:48:58 <herriojr> ?
Feb 18 15:49:44 <jbq> I think there's a bitmap API to recycle the underlying memory when you're done using it. I might be wrong.
Feb 18 15:55:30 <herriojr> I hope there is
Feb 18 15:55:58 <herriojr> trying to display images in a list gets pretty ugly pretty quick for scrolling
Feb 18 15:56:40 <anno^da_> does someone know the Regex pattern that passes patterns like this: 100,100,3324,234,20,123         (-> figure,figure,figure...)
Feb 18 15:56:40 <herriojr> I noticed the market uses some type of image pool, but when it writes the images to the view, there's almost no lag
Feb 18 15:57:57 <jbq> anno^da_: maybe something like [0-9]+(,[0-9]+)*
Feb 18 15:58:16 <vol> Ugh. Is there any way to query a MediaPlayer to see what its current state is?
Feb 18 15:58:40 <herriojr> jbq: that looks prettier than what I was going to suggest :)
Feb 18 15:58:40 <vol> state mismatch exceptions are a pain in the butt, especially if you're not synchronizing everything.
Feb 18 15:59:11 <jbq> herriojr: prettiness doesn't guarantee correctness, though.
Feb 18 15:59:40 <CardinalFang> anno^da_, Or, to capture the numbers (?:(\d+),?)+
Feb 18 15:59:45 <herriojr> true :)  Although, when I looked at it, I thought he wanted 3 characters per number...I'm already too tired to think today :)
Feb 18 16:01:56 <jbq> herriojr: well, you'd replace [0-9]+ by [0-9][0-9][0-9] (or whatever shortcuts your regex format might allow for that)
Feb 18 16:02:53 <herriojr> yes, that's what I was doing :)
Feb 18 16:03:30 <CardinalFang> Say, ain't paid apps supposed to show up in the Market any minute now?
Feb 18 16:03:57 <anno^da_> Thanks to jbq and CardinalFang :)
Feb 18 16:04:04 <anno^da_> I will try them
Feb 18 16:05:39 <herriojr> how do I enable heap updates for the client (so ddms can grab them?)
Feb 18 16:17:10 <herriojr> figured it out
Feb 18 16:35:25 <anno^da_> Does someone know why a Dialog doesnt get reopened when I change the screen orientation? I have opened the Dialog which is opened from a Activity which is placed in a TabActivity.
Feb 18 16:36:17 <KNY> anno^da_, when you change the screen orientation, the Activity is torn down and recreated
Feb 18 16:36:22 <marklar> anno^da_: I think that is something you have to handle yourself. I don't remember why but when I did it I had to recreate it on orientation change.
Feb 18 16:36:26 <KNY> you have to save the state and rebuild it
Feb 18 16:36:53 <KNY> romainguy has a pretty good writeup here: http://www.curious-creature.org/2009/02/16/faster-screen-orientation-change-with-android/
Feb 18 16:37:23 <anno^da_> well yeah I know that
Feb 18 16:37:25 <anno^da_> but
Feb 18 16:37:45 <anno^da_> when you open a dialog from a Activity without putting it into a TabAc... it gets recreated automatically
Feb 18 16:37:53 <anno^da_> Just thought that I missed sth. :)
Feb 18 16:39:02 <marklar> anno^da_: really? its been a while but I seem to remember that mine weren't being recreated in a normal activity
Feb 18 17:18:48 <fknecht> I want to insert calendar entries into the calendar database on the phone locally (NOT over the net!). As far as I understand it, there is no API for this in the SDK, right?
Feb 18 17:19:19 <fknecht> Anyone know if there is a 3rd party API that handles the DB directly?
Feb 18 17:20:04 <herriojr> you can access the Calendar as far as I know
Feb 18 17:21:29 <herriojr> yeah, you can, just do a search for Calendar
Feb 18 17:22:02 <herriojr> You'll be accessing the ContentProvider
Feb 18 17:23:19 <herriojr> well, at least they're undocumented
Feb 18 17:23:22 <herriojr> the provider is there
Feb 18 17:23:35 <fknecht> ah, ok. I found nothing in the docs
Feb 18 17:24:35 <herriojr> in the android source: ./packages/providers/CalendarProvider
Feb 18 17:25:29 <fknecht> In the source I found it. But how do you access it in the SDK?
Feb 18 17:25:45 <herriojr> you have to manually build the Uri
Feb 18 17:26:07 <herriojr> and for the ContentValues, you need to use string constants you create
Feb 18 17:26:34 <fknecht> Ok, so not an easy job at all
Feb 18 17:27:06 <herriojr> not hard, you just need to copy the Calendars.java file which contains the columns, etc.
Feb 18 17:27:23 <herriojr> and learn the organization of the interface
Feb 18 17:27:57 <herriojr> Uris:
Feb 18 17:28:05 <herriojr> instances/when/*/*
Feb 18 17:28:07 <herriojr> events
Feb 18 17:28:09 <herriojr> events/#
Feb 18 17:28:13 <herriojr> calendars
Feb 18 17:28:16 <herriojr> calendars/#
Feb 18 17:28:21 <herriojr> deleted_events
Feb 18 17:28:26 <herriojr> attendees
Feb 18 17:28:29 <fknecht> I had a look at the database directly. Quite hard to create events like that
Feb 18 17:28:29 <herriojr> attendees/#
Feb 18 17:29:22 <herriojr> you just need the Events columns
Feb 18 17:30:21 <fknecht> What about alerts and reminders?
Feb 18 17:30:40 <herriojr> same thing
Feb 18 17:31:50 <fknecht> Ok, I'll take a look. Haven't done anything with ContentProviders so far
Feb 18 17:32:00 <herriojr> to see what matches there are, look at line 3755 of ./packages/providers/CalendarProvider/src/com/android/providers/calendar
Feb 18 17:32:13 <herriojr> calendarprovider.java
Feb 18 17:32:14 <herriojr> that is
Feb 18 17:37:31 <herriojr> ./base/core/java/android/provider/Calendar.java
Feb 18 17:37:37 <herriojr> contains all the columns, etc.
Feb 18 17:37:47 <herriojr> including Uris
Feb 18 17:41:37 <fknecht> Which version of the source are we talking about? And where did you get it? I'm currently using only the gitweb
Feb 18 17:49:00 <herriojr> I can copy it and send it to you if you want
Feb 18 17:49:13 <herriojr> I check it out via git, so maybe not everything displays for you
Feb 18 17:49:37 <fknecht> That would be cool
Feb 18 17:50:19 <herriojr> I'll just throw it on pastebin
Feb 18 17:50:41 <fknecht> yeah, only see the kernel, platform and tools packages
Feb 18 17:51:37 <fknecht> So, Calendarprovider is what I can see (several versions actually), but the Calendar.java is what is interesting
Feb 18 17:54:18 <herriojr> yeah, I'll send it up to you
Feb 18 17:59:10 <fknecht> ok, thanks. pastebin is just fine
Feb 18 18:20:50 <herriojr> I'll have it up in just a sec for you
Feb 18 18:22:49 <herriojr> here's calendar.java
Feb 18 18:22:50 <herriojr> http://pastebin.ca/1341252
Feb 18 18:23:01 <herriojr> fknecht: hope that helps
Feb 18 18:26:14 <fknecht> herriojr: Thanks! Can't test it today because of another "accident" I have to take care of ;-)
Feb 18 18:28:39 <kencausey> some days it's just fighting one fire after another
Feb 18 19:06:36 <vol> I'm using HttpURLConnection to download a file from a web server. The file is just a simple text file. Is there a simpler way to do this than using HttpURLConnection?
Feb 18 19:08:34 <KNY> vol, can't java.io.File() handle remote URLs?
Feb 18 19:09:40 <vol> Can it?
Feb 18 19:10:17 <vol> In any event, I was looking for an "I'm Lazy" class that will handle remote connection and downloading for me and hand me a nice little byte array as a result.
Feb 18 19:13:33 <romainguy_> use the URL class
Feb 18 19:17:55 <ido--> romainguy, can you give out a few pointers how i would be able to create a vnc like application for android ?
Feb 18 19:18:01 <ido--> if its possible
Feb 18 19:18:17 <ido--> without getting the data directly from the framebuffer
Feb 18 19:19:43 <joakime> ido-- look at droidex and ddms
Feb 18 19:20:30 <romainguy_> ido--: you can't
Feb 18 19:20:43 <ido--> hrm.
Feb 18 19:21:16 <ido--> how about displaying a cursor "mouse" and imitating clicks ?
Feb 18 19:21:33 <ido--> for remote control ?
Feb 18 19:21:53 <romainguy_> nope
Feb 18 19:21:54 <ido--> clicks = finger presses
Feb 18 19:22:21 <ido--> is imitating clicks possible ?
Feb 18 19:22:37 <romainguy_> no
Feb 18 19:23:07 <KNY> vol, ah, yeah, I meant the URL class. Thanks, romainguy_
Feb 18 19:23:32 <ido--> how about recording audio and processing the raw data ? (not saving to a file)
Feb 18 19:23:58 <KNY> ido--, why do you need a cursor? the WinMo remote desktop viewer doesn't use one and it works just fine
Feb 18 19:24:12 <KNY> ido--, the API doesn't support raw audio stream yet, as far as I know
Feb 18 19:25:39 <ido--> anyway around raw audio stream ?
Feb 18 19:25:54 <ido--> afterall there are apps that are doing stuff with raw audio
Feb 18 19:26:04 <ido--> or so it seems.
Feb 18 19:28:43 <herriojr> just a quick dumb question, I have to set an OnFocusChange listener for each item in the list if I want it to do something when it gains focus, right?
Feb 18 19:29:08 <herriojr> I can't just set the onFocusChange listener for the list view
Feb 18 19:29:42 <herriojr> nobody has to answer that, sometimes it helps for me to write things to people to make sure I understand things properly
Feb 18 19:31:44 <KNY> herriojr, you can probably do something with setting it on the Adapter instead of every item in the list
Feb 18 19:31:49 <KNY> I'm not positive, though
Feb 18 19:32:46 <romainguy_> items in a list don't get focus
Feb 18 19:32:50 <romainguy_> they become selected
Feb 18 19:32:57 <romainguy_> use OnListItemSelectedListener or something like that
Feb 18 19:33:42 <herriojr> yup, ok
Feb 18 19:34:58 <mpardo> what are people finding is the easiest/best way to parse xml? I'd like to parse xml into objects
Feb 18 19:35:26 <herriojr> mpardo: depends on what you're talking about
Feb 18 19:36:00 <mpardo> what do you mean?
Feb 18 19:36:11 <herriojr> we use a SAX parser for some things
Feb 18 19:36:30 <herriojr> like network communication
Feb 18 19:36:37 <herriojr> for protocols
Feb 18 19:36:44 <mpardo> like apis
Feb 18 19:37:05 <herriojr> org.xml.sax.*
Feb 18 19:37:15 <herriojr> it's built in
Feb 18 19:37:55 <herriojr> does that help?
Feb 18 19:38:01 <mpardo> with sax is it pretty easy to just pick out an element by name?
Feb 18 19:39:09 <herriojr> extend DefaultHandler and override startDocument, endDocument, startElement, endElement
Feb 18 19:39:43 <mpardo> sounds like a lot of work
Feb 18 19:40:18 <mpardo> i was hoping there was something simpler, like in .net
Feb 18 19:40:36 <herriojr> I'm not super-knowledgeable about java, so there might be something better
Feb 18 19:40:48 <herriojr> you could always parse the xml into AttributeSets
Feb 18 19:40:56 <herriojr> or not
Feb 18 19:40:58 <mpardo> i think you may be right, because that's all i've seen so far
Feb 18 19:41:00 <herriojr> since those are for attributes
Feb 18 19:41:15 <herriojr> what exactly does .net do?
Feb 18 19:41:21 <herriojr> that helps out
Feb 18 19:41:36 <joakime> or use xmlpull parser - http://developer.android.com/reference/org/xmlpull/v1/package-summary.html
Feb 18 19:42:02 <mpardo> you load in xml to an xml object, then you can loop through elements creating element objects, getting values, etc
Feb 18 19:44:05 <herriojr> I'm always wary about loading all the xml up, but I'm assuming you're not dealing with large amounts of data
Feb 18 19:44:53 <herriojr> so it shouldn't be an issue
Feb 18 19:45:03 <mpardo> right
Feb 18 19:45:36 <mpardo> especially if it's not your own xml, but another site/service
Feb 18 19:47:11 <digitalspaghetti> i'm actually just writing a tutorial on a SAX-based parser right now
Feb 18 19:47:25 <digitalspaghetti> if you can hold on for a couple of hours
Feb 18 19:47:42 <herriojr> I should write some tutorials
Feb 18 19:48:05 <digitalspaghetti> it'll be up on http://android.ifies.org, and i'll post the source too to source.ifies.org
Feb 18 19:48:11 <mpardo> digitalspaghetti: ah cool
Feb 18 19:48:22 <herriojr> and I'd be writing it from an idiot's perspective
Feb 18 19:48:35 <digitalspaghetti> herriojr: thats what i do :)
Feb 18 19:48:35 <herriojr> well, that could be good or bad
Feb 18 19:48:50 <herriojr> I have the luxury of being an idiot is what I mean :)
Feb 18 19:48:51 <digitalspaghetti> also, i'm accepting tutorials on the site, i want to make it a good resource for people
Feb 18 19:49:00 <herriojr> ok
Feb 18 19:49:08 <herriojr> yeah, let me know if you want anything in particular
Feb 18 19:49:25 <digitalspaghetti> nope, just what takes your fancy :)
Feb 18 19:49:37 <herriojr> I do lots of varying things, so I have experience all over the place
Feb 18 19:49:56 <mpardo> i did some xml parsing in an app i did, but i wasn't happy with it
Feb 18 19:50:08 <herriojr> I was going to write one on extending views when I get around to it
Feb 18 19:50:25 <herriojr> but right now, I'm working 12+hours a day
Feb 18 19:50:31 <herriojr> so not going to happen
Feb 18 20:01:22 <herriojr> so in java, is there a way to hide inherited public functions?
Feb 18 20:01:29 <herriojr> sorry, it's probably a dumb question
Feb 18 20:01:40 <mpardo> why would you want to?
Feb 18 20:02:57 <herriojr> when extending a view, I want it to use a certain type of adapter, and instead of override setAdapter and doing a check in there, I wanted to put it in the argument so people using it could easily recognize they can't just use the regular ListAdapter
Feb 18 20:04:10 <mpardo> You should probably just override it to take FooListAdapter
Feb 18 20:04:52 <herriojr> so I can override setAdapter to take a different argument?
Feb 18 20:05:03 <herriojr> or a subclassed argument?
Feb 18 20:05:27 <mpardo> yes, as long as you super() the right class
Feb 18 20:05:28 <mpardo> i think
Feb 18 20:05:40 <herriojr> nah, it's complaining
Feb 18 20:05:53 <herriojr> I'm just sticking with the check inside of setAdapter
Feb 18 20:12:41 <herriojr> in java, is branch prediction handled via java, or by the processor?
Feb 18 20:13:23 <ido--> java
Feb 18 20:13:40 <ido--> the processer doesn't understand java bytecode
Feb 18 20:13:53 <herriojr> yes, but javaVM executes on the processor
Feb 18 20:13:56 <ido--> unless its in jazelle mode (but its not)
Feb 18 20:14:14 <ido--> then the the cpu predicts the javaVM code..
Feb 18 20:14:28 <ido--> hrm. i might be wrong here, since the javaVM can compile JIT
Feb 18 20:14:38 <ido--> and then it would branch predict
Feb 18 20:14:48 <ido--> but i think i read davlik does do that
Feb 18 20:14:51 <ido--> or something
Feb 18 20:14:58 <herriojr> but I was wondering if JavaVM gives a hint to the processor for the prediction if branches are converted directly to asm
Feb 18 20:15:49 <herriojr> anyways, I was just trying to figure out how to order some of my if statements
Feb 18 20:16:05 <ido--> asm ? or op codes ?
Feb 18 20:16:05 <herriojr> and to do that, I needed to know the algorithm
Feb 18 20:16:14 <herriojr> op codes I meant, but forgot the term
Feb 18 20:16:48 <ido--> wait till someone else who's more familiar with android answer you
Feb 18 20:17:08 <herriojr> ok
Feb 18 20:17:12 <kencausey> how about simply testing it?
Feb 18 20:17:50 <herriojr> I'm just going to assume it just predicts most frequent branch
Feb 18 20:18:34 <ctate> "bytecode"
Feb 18 20:19:03 <ctate> a virtual machine (Dalvik in this case) is free to try to implement whatever branch-prediction policy it wants, including "none"
Feb 18 20:19:30 <herriojr> ok
Feb 18 20:31:41 <ctate> in general branch prediction only matters when you have pipelined instruction fetch
Feb 18 20:32:06 <ctate> which tends to be a feature of silicon CPUs, not virtual ones
Feb 18 20:38:42 <herriojr> yeah, I don't know enough about VMs to really know what all gets done at the CPU level
Feb 18 20:39:04 <herriojr> I'm just used to programming in C
Feb 18 20:39:10 <kencausey> that is largely the point of VM, not to care
Feb 18 20:57:42 <mpardo> is it possible to find an xml element by path? ie: /items/item[id=0]/saleprice
Feb 18 21:00:28 <herriojr> I'm curious, why was limit not added as part of the query function for ContentResolver?
Feb 18 21:00:38 <herriojr> *as an argument for
Feb 18 21:05:21 <joakime> limits? we dont need more limits in android!
Feb 18 21:06:57 <herriojr> I ended up putting in a hack where my ContentProvider can be passed the limit as part of the Uri
Feb 18 21:40:42 <herriojr> so, invalidate() doesn't seem to be forcing the ListView to call bind() on the views again...is there a way I can force it to?
Feb 18 21:42:31 <romainguy_> herriojr: invalidate() is just for redraw
Feb 18 21:42:39 <romainguy_> you can call invalidateViews() but it's wasteful
Feb 18 21:42:53 <romainguy_> you should call notifyDataSetChanged() on your Adapter, if the data has changed
Feb 18 21:43:01 <romainguy_> or if the data has not changed call requestLayout() on ListView
Feb 18 21:43:02 <herriojr> ah, didn't think about that
Feb 18 21:43:25 <herriojr> is notifyDataSetChanged() or requestLayout() more efficient?
Feb 18 21:43:38 <romainguy_> requestLayout()
Feb 18 21:43:45 <romainguy_> but they don't have the same meaning
Feb 18 21:44:15 <herriojr> yes, I understand
Feb 18 21:44:49 <herriojr> will it keep the list at the same position?
Feb 18 21:44:55 <romainguy_> yes
Feb 18 21:44:57 <romainguy_> why wouldn't it?
Feb 18 21:45:06 <herriojr> I don't know, was just making sure :)
Feb 18 21:54:15 <digitalspaghetti> mpardo not round anymore?  just posted my SAX RSS Parser tutorial
Feb 19 02:04:35 <jasta> romainguy_: i'm heading to France on Apr 14th :)
Feb 19 02:13:07 <romainguy_> nice :)
Feb 19 02:13:18 <SanMehat> I'm going April 1st
Feb 19 02:13:31 <romainguy_> nice too :)
Feb 19 02:13:49 <jasta> SanMehat: really?  i'm flying to Dublin Apr 4th, France the next week :)
Feb 19 02:13:54 <SanMehat> hmm.
Feb 19 02:13:55 <jasta> doing a mini european tour
Feb 19 02:14:31 <SanMehat> we're going to be in dublin the 6 -> 8
Feb 19 02:16:09 <jasta> that is bizarre.  there is actually a chance i will see you :)
Feb 19 02:18:17 <jasta> i don't want to intrude on your honey moon, but if you're looking to hang out for dinner or something let me know
Feb 19 02:18:21 <jasta> nagaxen will be with me too, if you remember him
Feb 19 02:18:27 <jasta> (and 2 other friends of mine)
Feb 19 02:56:57 <jasta> what is the deal with the Home button not working in the latest builds?
