**** BEGIN LOGGING AT Mon Sep 10 02:59:58 2012 Sep 10 03:43:47 quick question: does the outermost view of a layout in xml (eg. often a linear layout) have a default id? is it android:id/content ? Sep 10 03:48:06 When drawing in an MapView Overlay, is there an easy way to make the canvas scale with zoom. Sep 10 03:48:48 briswolf: yes Sep 10 03:48:54 to both Sep 10 03:49:01 JakeWharton: thanks heaps Sep 10 03:49:08 although that's technically not the outermost view, you should consider it as such Sep 10 03:49:10 JakeWharton: didn't want to just assume Sep 10 03:53:45 Can I replace this view (the root view, right?) with a fragment at runtime? Or should I create a dummy view inside to replace with the fragment... Sep 10 03:54:12 you can attach a view to android.R.id.content Sep 10 03:54:34 a fragment, rather Sep 10 03:54:44 ok so inflate the fragment and then put it inside the linear layout Sep 10 03:54:55 as in, don't use a fragmentTransaction Sep 10 03:55:01 I will try it out Sep 10 03:58:35 So, when drawing in a MapView Overlay, is there an easy way to make the canvas scale with zoom. I am working on drawing routes. The path part is easy, however I want an arrow at the end and I need it to scale Sep 10 04:05:28 anyone have an idea? Sep 10 04:05:57 epsilonorion: sorry, no. I am struggling with the basics :/ Sep 10 04:06:20 briswolf: np, thanks. I saw you working on fragments. I was there a while ago, but it is definitely fun Sep 10 04:13:31 I am updating ListView's data adpater in local service and then calling notifyDataSetChanged but ListView data gets updated only when I touch screen. any pointers what might be going wrong? Sep 10 04:14:21 sacdroid: are you calling notifyDataSetChanged from the ui thread? Sep 10 04:14:32 yes Sep 10 04:14:42 briswolf: I'm out of ideas :P Sep 10 04:14:46 sorry Sep 10 04:14:50 ok :) Sep 10 04:15:12 sacdroid: sounds like a strange issue though Sep 10 04:15:18 hmm Sep 10 04:15:53 sacdroid: have you tried it from just a thread? I don't believe the service would interfere (you haven't put the service in a remote process or anything like that right?) Sep 10 04:16:13 no, its Local Service Sep 10 04:16:35 yeah. what kind of adapter are you using? just an arrayAdapter? Sep 10 04:16:48 its ArrayAdapter. Sep 10 04:17:24 its Fragement which contains ListView and this Fragement is added dynamically! Sep 10 04:17:36 in ViewPager... Sep 10 04:18:43 I have a listview in a fragment in a viewpager and it works ok, I am updating an array in a bg thread and then calling notifyDataSetChanged from the uiThread and it is working, so sorry I don't have any ideas :/ wish I could help. Sep 10 04:19:37 ok np :) Sep 10 04:20:38 I assume in your fragment you are calling getActivity().runOnUiThread(new Runnable(){.....}); to call notifyDSC Sep 10 04:24:33 briswolf: no Sep 10 04:25:12 sacdroid: calling update from the service? what if you make the service issue a callback to the fragment... it probably won't change much Sep 10 04:26:24 sacdroid: I am not sure what you are doing, but if the service is building/maintaining a list, maybe when that list changes the service can issue a callback to registered listeners, and those listeners could copy the list and then update the listview Sep 10 04:26:32 don't really need to copy I suppose Sep 10 04:27:12 seems like the service shouldn't know about the UI implementation though, from a compartmentalising point of view (imo) Sep 10 04:28:46 yes, I am doing exactly what you mention and I am not copying as same underlying data is being updated by service, I am just invoking notifyDataSetChanged from a listener method which is called by service Sep 10 04:29:39 sacdroid: so the listener, is it in your fragment class? what is the code you use to run on the ui thread, out of curiosity Sep 10 04:29:48 does this listener method which is in turn calls notifyDataSetChanged needs to be call using runOnUiThread? Sep 10 04:29:59 the listener doesn't Sep 10 04:30:06 but I would think that notifyDataSetChanged does Sep 10 04:30:14 Listner == Fragement Sep 10 04:30:38 what else are you doing in the function? Sep 10 04:30:40 My listener is Fragement Sep 10 04:30:47 nothing else. Sep 10 04:31:05 its just call to notifyDataSetChanged on adapter . Sep 10 04:31:23 sacdroid: so is the call to notifyDSC happening on the main thread? Sep 10 04:31:43 the ui thread rather Sep 10 04:32:01 I assume in your service you create a background/worker thread Sep 10 04:32:11 Its not, I guess. sorry. Let me try using runOnUiThread. Sep 10 04:32:17 cool yeah Sep 10 04:32:41 thx :) Sep 10 04:33:24 I am still confused - I want to click on an item in a listview, and then have a new activity launch which displays a fragment depending upon which item was clicked Sep 10 04:33:36 of course on a tablet I would not bother with the new activity Sep 10 04:34:22 so, what is one possible way to do this? do I need to store a static array of fragments by index, and then pass that index into the activity in an extra, and then lookup the fragment in the array by index and display it on the activity? Sep 10 04:34:53 * briswolf thinks he is missing some basic concepts Sep 10 04:35:56 actually I think I might just replace the listview fragment with my implementation fragment Sep 10 04:36:00 yes... Sep 10 04:36:06 You dont have to save array of fragements Sep 10 04:36:28 sacdroid: how do I communicate to the activity which fragment to show? Sep 10 04:37:14 Onclick of listview item just pass data which will be shown in fragment as parcable using "extras" Sep 10 04:37:35 and construct fragement or activity using passed data, Sep 10 04:37:48 each fragment is a completely different layout and code Sep 10 04:38:08 my list is things like "barcode scanning", "fingerprint image capture" etc Sep 10 04:38:22 so I have a fragment implemented (along with layout) to perform those tasks Sep 10 04:38:39 I guess I don Sep 10 04:38:45 t understand how parcelable works Sep 10 04:39:05 I will try for now just replacing my listview with the fragment and put the listview on the backstack Sep 10 04:39:23 should give much the same effect (in fact it will keep my tabbar visible which is probably better) Sep 10 04:39:30 your item click logic show decide which fragment should be constructed based on item clicked. Sep 10 04:39:51 sacdroid: ok, well I will look into that option thanks :) Sep 10 04:40:17 :) Sep 10 04:53:27 sacdroid: so to continue me being dumb, when I create the activity (fragmentactivity) what is the easiest way to display the given fragment on the screen - do I have to first call setContentView and pass in a simple/empty layout (with *something* to put the fragment on/in, what?) and then replace it somehow? or can I bypass setContentView altogether? Sep 10 04:55:55 I am no expert, but I guess setContentView which will set up layout with place holder for laout. Sep 10 04:56:06 place holder for fragement* Sep 10 04:56:17 sacdroid: yeah, ok. is that like any view? Sep 10 04:56:27 yes. Sep 10 04:56:31 does the fragment go inside that placeholder or replace it outright Sep 10 04:56:34 so replace it outright Sep 10 04:56:45 and I guess I use the id of the placeholder in a fragmenttransaction Sep 10 04:56:49 I will try it out :) Sep 10 04:56:54 yes, Sep 10 05:03:04 omg, why does all the http clients I can find for android suck? I'm currently debugging one that I had to fork (to add a feature I needed), and I'm stuck on a deadlock because the call to org.apache.http.impl.client.DefaultHttpClient::execute is blocking forever Sep 10 05:04:44 anyone familiar or have an idea on how to scale a drawn image (canvas) in an overlay when zooming in or out Sep 10 05:06:39 epsilonorion, maps? Sep 10 05:07:27 yes, mapview. I am create a routeoverlay between points. The route path is easy since it scales due to the points, however I need to show direction with an arrow. I am simply drawing a triangle on the end, but it obviously doesn't scale Sep 10 05:09:29 you might try getting the lat/lon of apposing corners and converting them to pixel x/y values and drawing to that specific rectangle Sep 10 05:09:50 I had to make a tiling system for mapview and that's how I scaled the tiles Sep 10 05:12:30 So you do this once to get a good value to hold as a scaling factor when doing this. Kind of a linear weight? Sep 10 05:12:45 nope, on every draw Sep 10 05:13:45 org.apache.http.impl.client.DefaultHttpClient Sep 10 05:13:46 bah Sep 10 05:13:50 http://pastebin.com/i4tGSHpq Sep 10 05:14:00 ^ where d is the drawable Sep 10 05:16:59 I think i see what you were saying, but how do you control the scaling specifically. Are you using the values to create a scaling factor, or simply coming up with a base rectangle when first started and draw in that bounded box? Sep 10 05:17:16 I do see how you are grabbing your bounds though Sep 10 05:19:03 the scaling factor is handled by the lat/lon box Sep 10 05:19:47 think of it as drawing on the map, and a separate viewer is doing the scaling/translating Sep 10 05:26:10 any particular way you are getting the upperleft or lowerright gps points of the view Sep 10 05:26:25 well, it's complicated ;) Sep 10 05:26:39 but it's a part of how the tiles are defined Sep 10 05:26:50 centered on a lat/lon and covering a given span Sep 10 05:27:23 the span changes with the zoom, but that's just because the tiles cover more area as you zoom out Sep 10 05:30:39 question: I have an API key for consuming data from a 3rd party. I want to share my source on github but I don't want to hand out my own API key - is there a way to include it from some external file that isn't included in github? I was thinking just put it in some CONSTANTS.java file and excluding that file from the commits - any other suggestions? Sep 10 05:33:06 put it in a properties file that you .gitignore Sep 10 05:45:50 thanks JakeWharton Sep 10 05:47:40 bleh. i have a general java question, i shoudl know the answer but i forget the specifics. so polymorphism. suppose ClassB extends ClassA. So what's the difference in ClassA instance = new ClassB() versus ClassB instance = new ClassB(); Sep 10 05:48:05 you can't call ClassB-only methods on 'instance' Sep 10 05:48:22 unless you cast the instance to ClassB type Sep 10 05:48:25 ah ok Sep 10 05:48:27 thanks Sep 10 05:49:40 any reason why you would want to do that? i mean, i understand if i take a parameter as a base type, i don't care about a subclasses stuff in the context of that parameter Sep 10 05:50:26 speakingcode: well sometimes you would be building a list of the base type, or something similar? Sep 10 05:51:15 but when explicitly instantiating an object of a class, why would one want to instantiate a subclass as a base class? why not just instantiate a subclass as the subclass, Sep 10 05:51:51 for testing, future-proofing, etc. Sep 10 05:51:55 i.e. why do ClassA o = new classB() instead of ClassB o = new ClassB()? whats the advantage Sep 10 05:52:14 speakingcode: so your code only can call methods of the base class Sep 10 05:52:16 in practice, you should always use the most abstract version of a type Sep 10 05:52:21 If ClassB doesn't introduce any new methods, just new behavior Sep 10 05:53:06 ahhh so if classB overwrites a method, but I instantiate as ClassA, then the classA (i.e. base class) version of the method will execute when i do instance.method() Sep 10 05:53:06 ? Sep 10 05:53:15 No Sep 10 05:54:17 briswolf i hear you, but if i don't want anything from the subclass, why use it at all? i know this sounds silly but i just think i'm forgetting something key about this Sep 10 05:54:50 speakingcode: I've done it, say I have a comms class. then the subclasses are like bluetoothcomms, usbcomms, etc. These classes might have specific functionality Sep 10 05:54:57 but I want all my code to only use comms functions Sep 10 05:55:04 so that I can interchange between usb, bluetooth etc Sep 10 05:55:32 If I need to use specific functionality I can use if instanceof ... and downcast to the specific type Sep 10 05:55:47 nod, ok, so you type your parameters in methods as the base class, i get that Sep 10 05:55:54 so at the start of my program I have like Comms comms = new USBComms(); Sep 10 05:56:09 or Comms comms = new BluetoothComms(); Sep 10 05:57:09 nod. why not do BluetoothComms comms = new BluetoothComms()... if BluetoothComms() extends Comms (or implements that interface) it's still interchangable Sep 10 05:57:27 because then you can't swap the impl Sep 10 05:58:32 swap? so you mean, at some point Comms comms = new Bluetooth()... then later on say comms = new OtherCommsSubclass() Sep 10 05:58:49 you can't write BluetoothComms comms = new UsbComms(); Sep 10 05:58:58 there might be also other refactoring you have to do Sep 10 05:59:07 if you weren't constrained to using the comms class everywhere Sep 10 05:59:28 like so many things, it isn't like "you must do it this way" but if you do it that way you might avoid more work later Sep 10 05:59:43 hmmm Sep 10 05:59:59 i hear ya just still not seeing this clearly. hmph Sep 10 06:01:49 when i take a parameter, i always take the "most abstract" or highest base class, i get that - then i can pass any subclass or implementation as an arg to that method... but when i'm instantiating explicitly, why declare it as a base class instead of the subclass, i dont get the precise difference Sep 10 06:03:04 because it's best practice and future-proofs you Sep 10 06:03:20 how? what's the mechanical difference Sep 10 06:03:24 if it is local to a function and that reference only lives for a line or two then there is probably little difference Sep 10 06:03:42 but if it is an ivar... then all the other stuff Sep 10 06:03:53 because it forces you to write code against a more abstract API Sep 10 06:04:50 so that when your requirements change and you have to swap your LinkedList for a CopyOnWriteArrayList you only have to change the instantiation Sep 10 06:05:04 ah Sep 10 06:05:07 that makes sense Sep 10 06:08:31 so mehcanically there isn't much difference, but it generalizes the code in the same way that one would generalize methods by using the "most abstract" class/interface when typing a parameter Sep 10 06:10:08 that discussion was probably way more verbose than necessary. thanks for putting up with me ;-) Sep 10 06:10:32 explain --verbose Sep 10 06:10:41 hah, no such thing as a java discussion which is too verbose Sep 10 06:11:33 Java discussions aren't over until you're talking about heaps and stacks Sep 10 06:12:03 lol yeah. well with anything technical i try to be only as verbose as necessary (which can often be quite wordy) - but anything extra then the absolute necessary tends to confuse or cloud the point Sep 10 07:07:39 On iOS, OpenGL ES 2 contexts can share resources between them and multiple contexts can be bound to multiple threads at the same time (one context per thread, and one thread per context). Sep 10 07:07:52 Are there limitations on each of these on Android devices? Sep 10 07:07:56 Either. Sep 10 07:12:16 Hey Guys, I'm looking at IoSched code for designing my app again for single pane and multi pane, but it all looks very messy is there any better reference for doing it? Sep 10 07:22:51 brickhead: iosched is as good as it gets Sep 10 07:28:26 g00s: so my query is we have booth Single Pane and Multi pane activity register Intent-filter for a perticular mime type but who does it decides which one to call at run time Sep 10 07:29:40 It's usually just 1 activity Sep 10 07:29:44 With different layouts Sep 10 07:30:02 has anybody ever debugged through an AIDL call into a remote service?... Sep 10 07:30:13 or can you get breakpoints to fire in a remote service? Sep 10 07:30:29 is there a trick? Sep 10 07:31:12 na what they done is created single pane activities and a multi pane activity which says I've all these fragments and I could handle their mime types Sep 10 07:31:47 All our hard|work is gone. Sep 10 07:46:50 Hola #android-dev Sep 10 07:57:48 hola Sep 10 07:58:32 speakingcode: how's your day goin'? Sep 10 07:59:08 about to end, and it's been awesome. Sep 10 07:59:10 oh this is wierd Sep 10 07:59:13 I have 4 breakpoints I can't toggle off in eclipse. Sep 10 07:59:32 try restarting eclipse - it gets funky sometimes ;-) Sep 10 07:59:51 thanks for asking, how is your day? Sep 10 08:00:25 well, I got up at least an hour earlier than I should have Sep 10 08:00:30 which was a bad start Sep 10 08:01:16 I work on a helpdesk, and I wasn't convinced that there would be anyone here at 8am, so I came in early. Sep 10 08:01:45 turns out there was someone here, and I could have had some more of that precious, precious sleep I love so dearly. Sep 10 08:02:38 speakingcode: have you seen the X-Files? Sep 10 08:04:13 i am watching x-files now, season 1 episode 7 - ghost in the machine Sep 10 08:04:42 pts\3: I'm on season 1 as well, last or second last episode Sep 10 08:04:44 pts\3: old school Sep 10 08:04:54 pts\3: respect. Sep 10 08:05:11 there are way more one-liners in that show than I remembered Sep 10 08:05:30 * lut4rp will never forget the last episode of season 1 Sep 10 08:05:39 Even though I watched it years and years ago Sep 10 08:06:15 lut4rp: I was only 6 when the X-Files started, so Season 1 kind of passed me by Sep 10 08:06:19 I have millis and is it possible to format it to this format? : "Mon Sep 10, 1:36 PM" Sep 10 08:06:29 let us all give a moment of silence for how badly x-files ended... Sep 10 08:06:50 napster: everything is possible. The Truth Is Out There. Sep 10 08:06:50 napster: you will have to create an instance of Date Sep 10 08:07:30 http://www.roseindia.net/java/java-conversion/MillisecondToDate.shtml Sep 10 08:07:45 briswolf: Yes I have one instance already, its just that I need to format it Sep 10 08:07:59 try SimpleDateFormat Sep 10 08:08:14 there you are, let me try Sep 10 08:08:18 briswolf: yeah, I'm planning on jumping ship when David Duchovney does. Sep 10 08:08:20 ty briswolf Sep 10 08:08:54 or this: http://developer.android.com/reference/java/text/DateFormat.html Sep 10 08:11:04 ok, thank you briswolf Sep 10 08:12:47 napster: you know what's cool? a BILLION dollars Sep 10 08:12:49 hah Sep 10 08:13:07 briswolf: Give me your PayPal id ;) Sep 10 08:33:08 damn you Lint! you are currently warning me that an Import that isn't there is not being used! Sep 10 08:38:14 try this remove the warning :P Sep 10 08:38:15 Sep 10 08:38:19 ^^ Sep 10 08:52:07 Is anynon know how to fix "Too many fields" dalvik error? My Android App is made of 25 library projects Sep 10 08:57:26 Use less :p Sep 10 08:58:18 Is anyone here familiar with the ADK? I need to know whether two devices that work by USB would have any luck working through Android. ( http://goo.gl/MjOcU ) and ( http://www.aimpro21.com/prod_ir606.asp ). Sep 10 08:59:20 I have them on my desk, and I assumed that I could use UsbManager to access them. Sep 10 09:04:51 Knossos: are they just USB devices (i.e. you can plug them into a computer?) Sep 10 09:05:05 Pretty much Sep 10 09:05:19 if they use bulk usb transfers then yes you can work with them Sep 10 09:05:27 you will have to write you own "drivers" Sep 10 09:05:40 the android USB host type code is very similar to libUsb Sep 10 09:05:59 so if there is any code which already demonstrates that you will find it not to difficult to port Sep 10 09:06:07 otherwise you will have to reverse engineer the USB protocol Sep 10 09:06:15 which isn't fun without a protocol analyser Sep 10 09:06:20 and even then it's not fun ;) Sep 10 09:06:35 Anyone know how to implement a guassian blur animation? Sep 10 09:08:17 Ok, well it is at least a start to know that I can use these devices. Unfortunately, I am not certain where I should even start with creating my own driver. This may be a long road. Sep 10 09:09:27 Knossos sorry I'm real busy at the moment :/ Sep 10 09:09:59 Knossos otherwise I'd give more pointers. 7pm and working for a deadline. I shouldn't even be in here ;) Sep 10 09:10:00 hah Sep 10 09:10:02 No problem, as I said. At least I know that the devices have a possibility of working :D Sep 10 09:10:17 That was really the main thing. Sep 10 09:26:02 How can I get listpreferences displayed text of selected item and not only the value Sep 10 09:30:02 startActivityForResult() should give (based on the intent/activity defined) give RESULT_OK and RESULT_CANCELED, is the later all ways -1? Sep 10 09:30:18 hmm ignore that Sep 10 09:30:53 public static final int RESULT_CANCELED Constant Value: 0 (0x00000000) Sep 10 09:30:55 crap... Sep 10 09:31:40 It doesn't have to be one of those Sep 10 09:31:52 it can even be 2 Sep 10 09:35:18 is there a way to extract the kernel config if adb pull /proc/config.gz doesnt work? Sep 10 09:38:05 your app depends on the kernel config? Sep 10 09:40:26 i am trying to compile a kernel and wasn't sure where to ask Sep 10 09:41:09 well... not here - #android-root if appropriate, or the android-porting or android-building google groups Sep 10 09:41:24 oh cool thanks didnt know about those Sep 10 09:41:46 you knew about #android-root, because it's in the topic of this channel, which you read when you joined it Sep 10 09:42:56 well i more ment porting i think that one would be the right one Sep 10 09:46:12 ok :) Sep 10 10:06:45 hi, is it possible to force a layouting pass different from requestLayout? Sep 10 10:07:01 requestLayout has the property that it only performs the layout pass once the control is back to the main UI loop Sep 10 10:07:19 i would like to perform layout and then continue in my code (this is for purposes of arranging views for a screenshot) Sep 10 10:12:31 Is there a website that shows the graphical evolution of standard wigets? Sep 10 10:12:51 lasserix: you mean the creation ? Sep 10 10:13:39 Uhh not as much as just a sequence of images showing each widget's drawables on subsequent versions of the os Sep 10 10:14:52 Like http://androiddrawableexplorer.appspot.com/ is showing 2.2 but I want to see for say a spinner, its drawables from 1.0 to ics or something Sep 10 10:15:12 Even though few things could be more useless ;p Sep 10 10:31:33 to clarify a little further: We have to capture a camera preview and overlay a logo on top of it.. Sep 10 10:32:00 so we got this camera preview decoding part allright.. Sep 10 10:32:06 [it's a bit of a hassle, but ok] Sep 10 10:32:10 If I have a lot of constants for uses in switches and the like, is it better practice to make one static class containing all of the constants, or declare them per class where they are used / most likely to be used? Sep 10 10:32:11 tapas: just put your logo in a seperate view and throw it on top of your image view for the camera Sep 10 10:32:22 funktronic: that's what we do Sep 10 10:32:31 funktronic: this part works great.. Sep 10 10:32:56 funktronic: then when the user hits capture we do the following: hide the camera surface, display the captured preview frame instead Sep 10 10:33:28 funktronic: the logo is still visible. then we create a canvas and tell the layout holding the logo and the preview frame to render itself.. Sep 10 10:33:42 then we hide the logo and preview frame and display the result image.. Sep 10 10:34:26 so what's the issue Sep 10 10:34:30 we need to have this strict order of operations and you can clearly see that there should be layout passes inbetween some steps, to make sure views are gone, others are showing, etc.. Sep 10 10:35:02 it seems that the layout.draw(Canvas) call seems to honour visibility.. Sep 10 10:36:49 funktronic: the issue is that the drawn image (i.e. the one created by layout.draw(c)) seems to have the logo in it twice (i only judge this from some alpha values being too high) Sep 10 10:37:32 ah, well you can hold references to the views and maniputlate them in your activity Sep 10 10:38:23 funktronic: let me show you a code snippet.. maybe you see something obviously wrong.. Sep 10 10:39:23 http://pastesite.com/43485 Sep 10 10:39:32 the "intersting" part starts at line 46 or so Sep 10 10:41:23 maybe the differences in the overlay over the preview surface and the rendered result image also stems from the fact, that the result image's resolution is bound to the view layout Sep 10 10:41:30 while the original logo is much bigger.. Sep 10 10:41:40 so the filtering algorithms work differently.. Sep 10 10:43:31 i'll play around a little.. Sep 10 10:43:48 what'd be the best way to check the backlight brightness while testing on the emulator? Sep 10 10:44:09 tapas: nothing obvious, but don't have time to look at it in super detail. sorry Sep 10 10:44:38 hi all, i'm trying to open a URL; i set the intent up okay, but get an error on startActivity(browserIntent); Sep 10 10:44:38 funktronic: thanks for the look thoug.h,, Sep 10 10:44:43 hmm, i just discovered something.. Sep 10 10:44:59 if i don't even render, but just show the camera preview frame and the overlay it already looks different.. Sep 10 10:45:37 so composition with a camera surface and a transparent overlay works different from a composition of a static imageview and a transparent overlay... Sep 10 10:45:40 interesting.. Sep 10 10:50:43 hello Sep 10 10:51:26 i cannot get a logcat from any of my builds, how can i ensure that connection? Sep 10 10:54:48 ah right, so, startActivity() must be called from inside Activity class? Sep 10 10:55:05 startActivity is a member of the Activity class? Sep 10 10:55:30 member of context Sep 10 10:55:48 you can check on d.android.com ... Sep 10 10:55:53 thx Sep 10 10:56:26 so if my class, extends context, i can then do startActivity? Sep 10 10:56:29 i start activity y from activity x with onStartActivityForResult() activity can then start some other activity z with startActivityForResult() on android 2.3.3 this works ok but with ICS the main activity's (x) onCreate, on Start etc are called multiple (ie. over 30) times Sep 10 10:56:32 being a bit dim today Sep 10 10:56:34 how should i go on about solving this? Sep 10 10:57:21 (mean that i am) Sep 10 11:01:02 In a cursor adapter in the bindview method I have to find the ids of the textviews to assign the values from the cursor, can I declare just one textview as a field to the class and reuse it? Or should I declare it a local variable explictly in the bindview call? Sep 10 11:03:50 Can I write some debug info to bundle with the default Android market stacktraces? Sep 10 11:06:03 how do i get a pointer to the instance of my main activity? Sep 10 11:07:07 MainActivity.this Sep 10 11:09:37 ah, thanks, didn't work though Sep 10 11:09:55 i have ... public class AppActivity extends Activity Sep 10 11:10:26 is there a single instance of this somewhere? Sep 10 11:10:41 i cannot get a logcat from any of my builds, how can i ensure that connection? Sep 10 11:11:00 No, MrQwak Sep 10 11:11:07 If you need it somewhere, pass a reference Sep 10 11:12:11 i need to call a member function Sep 10 11:12:24 have no idea what the instance of AppActivity would be Sep 10 11:13:03 ok, so alpha compositing works different over a surfaceview than over an image view.. Sep 10 11:13:18 that's annoying. i wonder if there's a way to make both compositing algorithms the same.. Sep 10 11:13:46 [i.e. having a transparent imageview on top of a surfaceview vs. one on top of another imageview] Sep 10 11:15:37 okay, i'm doing something really wrong here... Sep 10 11:15:46 trying to open a URL in browser Sep 10 11:16:01 so i have ... Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.mrqwak.com")); Sep 10 11:16:14 then startActivity(browserIntent); Sep 10 11:17:18 startActivity needs to be inside context class? or activity class. is that correct? Sep 10 11:24:47 http://pastebin.com/JvPJ9kYc here's my problem, how should i go on about solving it? Sep 10 11:25:40 hey, I'm using an imageview to display an imageuri Sep 10 11:25:46 however, the image changes from time to time, the uri doesn't Sep 10 11:25:51 how can I get the imageview to redraw? Sep 10 11:25:53 .invalidate() doesn't seem to do anything Sep 10 11:31:15 anyone? Sep 10 11:31:52 You have to set the image again Sep 10 11:33:41 how about my problem? Sep 10 11:52:23 Anyone have a link to how to do a listview with the "tab" that pops up indicating what letter you're at in the listview sequence? Sep 10 11:55:18 SimonVT: how? Sep 10 11:55:24 if i just recall setimageuri, nothing changes Sep 10 11:59:20 Look at how setImageUri works Sep 10 12:00:53 hi, if i wanna do a list view with: IMAGE TEXT IMAGE - i have the 2 images width = wrap_content and the TEXT width to fill_parent i cant see the image on right hand side of text Sep 10 12:00:54 any ideas Sep 10 12:02:53 how to get middle item to fill all unused space? Sep 10 12:03:14 http://pastebin.com/JvPJ9kYc here's my problem, how should i go on about solving it? Sep 10 12:04:09 is there any way to tell android how to do compositing between different (transparent) views short of doing the composition oneself? Sep 10 12:05:02 Is there an app that monitors a specific application that downloads data from the network, to know the source? Sep 10 12:18:01 sylon Sep 10 12:18:29 use a linearlayout wrap content width on both images and set layoutwidth to 1 on the textview with width="0dp" Sep 10 12:18:48 setting layout weight = 1 on the TV will make it take up remaining space Sep 10 12:23:33 Omar I've heard if you root your phone you can install wiresharck and packet analyze Sep 10 12:25:23 lasserix: thanks i figured it out eventually Sep 10 12:45:05 hey Sep 10 12:45:33 does any1here knows a good place to get some backround images for my game application so it won't be white and borring? Sep 10 12:58:18 sasson: try the internet, I hear there's a lot of neat stuff there. Sep 10 12:58:24 alternately, hire an artist??? Sep 10 12:58:48 sasson: get a camera. Find a sunset. Sep 10 12:59:16 or a kitten. internet loves those Sep 10 12:59:20 this is true. Sep 10 12:59:26 don't get a kitten just for a cute picture, though. Sep 10 12:59:36 google for 'stock photo'? Sep 10 12:59:39 If you're not ready for a lifelong kitty commitment, just take a picture of your friend's kitten. Sep 10 12:59:46 or you could find a kitty and- oh god damn you lov Sep 10 12:59:53 :3 Sep 10 12:59:54 sasson what kind of game is it? Sep 10 13:05:15 Hi, does it exists a motherboard with arm cpu, gps, 3G, sim slot, video output and android, Sep 10 13:05:41 already found something a while ago but don't remember the name Sep 10 13:05:58 without screen Sep 10 13:06:40 like raspberry but with gps/3G/sim Sep 10 13:12:15 With video out and telephony, I don't know. Sep 10 13:12:23 there isn't a huge market for an almost-cellphone I would imagine Sep 10 13:19:23 Is there a way to open the PreferenceScreen that has your config, via an intent or something? Sep 10 13:19:29 I'd like to open it but not through the standard menu button Sep 10 13:23:42 uh, yes? Sep 10 13:23:56 you don't HAVE to use menus to start intents :P Sep 10 13:25:20 lov, right but if its XML im not sure what the Intent class name is Sep 10 13:25:58 what would i pass for the class? Sep 10 13:26:21 o_O Sep 10 13:26:28 are you using a PreferenceActivity?... Sep 10 13:26:37 how exactly are you showing your preferences? Sep 10 13:26:39 oh wait Sep 10 13:26:42 LOL Sep 10 13:26:56 wow its been a while since i've touched this, i do have a screen an activity who knew Sep 10 13:26:57 :P Sep 10 13:27:03 derp. Sep 10 13:27:09 haha thanks lov Sep 10 13:27:41 lov, thanks anyway :) Sep 10 13:28:26 VinS: I'm curious what you're planning. You could always find an old cellphone that has video out, like an original galaxy S, and physically disconnect the touchscreen Sep 10 13:28:34 (assuming that you're ok with that level of surgery) Sep 10 13:28:59 obviously this isn't a great plan if you want to roll something out on 1000 devices, but if you want to do that you'd probably just talk to a manufacturer. Sep 10 13:28:59 JoyRideAlpha: did yu try adb logcat on the console? Sep 10 13:29:08 JoyRideAlpha: or just using eclipse or another IDE? Sep 10 13:29:23 it seems eclipse likes to lose the connection sometimes Sep 10 13:30:01 I need to know. Say a PHP form contains 3 submit buttons with different names. What POST data would be sent? Sep 10 13:30:26 Komak57: HTML form Sep 10 13:30:52 lov, in fact the screen / video output is not a requirement Sep 10 13:31:18 Leeds, yes. Sep 10 13:31:26 not PHP Sep 10 13:31:40 Komak57: I would very, very strongly suggest that you learn what HTTP and HTML are, and how they work. Sep 10 13:31:42 lov, I'd like to do a little tracking system with low consumption based on sms to activate the tracking, launch GPS and 3G to transfert data Sep 10 13:32:04 Komak57: use something like wireshark to look at what's actually being sent by your browser; it's very educational. Sep 10 13:32:44 VinS: there's a surprisingly large number of people who want to do this :P Sep 10 13:32:47 lov: you missed the guy in #android the other day who had fired up wireshark, only to discover his tablet was apparently transmitting malformed fibre channel packets Sep 10 13:32:53 Leeds: nice Sep 10 13:33:07 lol Sep 10 13:33:07 VinS: does it have to be android? There's probably purpose built equipment that already does this. Sep 10 13:33:22 sometimes you need more than just the right tool - you need to have more than the barest understanding of how that tool works Sep 10 13:33:34 ha Sep 10 13:33:35 lov, i've used HTML and PHP before, I'm just unsure how should be used with HTTPClient to press the submit button. Sep 10 13:34:02 Komak57: you need to learn what you're actually doing instead of just copy/pasting, is what I'm saying. Sep 10 13:34:13 learn about HTTP, and learn how form submissions work Sep 10 13:34:17 read RFC-1918 or whatever it is Sep 10 13:34:18 what is that input value o_O Sep 10 13:34:29 hrnt: " IN (Day) " Sep 10 13:34:30 hrnt: yeah I don't even want to think about it. Sep 10 13:34:30 >_> Sep 10 13:34:40
