[android-developers] Re: How to decode large resolution Images

[vishal bhoj]

Can Anyone help me on this ?

 Hello All,

 I want to decode high resolution pics something like 8 mega pixel
 images and view it. when I try to decode them I get out of memory
 exception. Decoding of single 8 mega pixel also fails . From the
 Imagamanager code and other post I could use BitmapFactory.Options
 inJustDecodeBounds I could get a scaled down version of the Image .

  Bitmap Bm =
   BitmapFactory.decodeResource(getResources
 (),R.drawable.two,opts);
   opts.inJustDecodeBounds=false;
   opts.inSampleSize =8;
  Bm =  BitmapFactory.decodeResource(getResources(),R.drawable.two,
 opts);
   imageView.setImageBitmap(Bm);

 Is there any way to decode part of the Image and fill it on the screen
 and by scrolling decode other reagion of the image and display it.

 Any pointers on this would be appreciated,


  Thanks in advance,

 Bhoj

You need to statically link it into your app (sorry I can't help with
exactly how to do this with ADT, I do my work in the platform build system).

[android-developers] Re: Android 1.5: How to get the BT state?

[Nick Pelly]

There is a simple bug in your code. Try looking in the source for
other examples of the use of BLUETOOTH_STATE_CHANGED and you should
quickly see what you have done wrong.

Sorry not going to spoon feed you for private API's.

 The action is fine but the states are always 404. So there is no state

action
android:name=android.bluetooth.intent.action.REMOTE_DEVICE_FOUND /

android:name=android.bluetooth.intent.action.BONDING_CREATED /

After testing with Android 1.5 I recognized that only:

action
android:name=android.bluetooth.intent.action.BLUETOOTH_STATE_CHANGED 
/

   1) These are not part of the public API. If you use them it is at your 
   own
   risk, and your app will probably break again going forward beyond 
   cupcake.

   2) Your question is easily answered by looking at the source.

       /** Broadcast when the local Bluetooth device state changes, for 
   example
        *  when Bluetooth is enabled. Will contain int extra's 
   BLUETOOTH_STATE
   and
        *  BLUETOOTH_PREVIOUS_STATE. */
       @SdkConstant(SdkConstantType.BROADCAST_INTENT_ACTION)
       public static final String BLUETOOTH_STATE_CHANGED_ACTION =
           android.bluetooth.intent.action.BLUETOOTH_STATE_CHANGED;

is available.

How can I detect the specific state of Bluetooth in 1.5? With the
settings I can only differentiate between BT on and off.

I'm looking forward reading your answer.

[android-developers] Re: Update application from the Android Market

[Mariano Kamp]

How do you know that the process is still running?
I've never seen this behavior. It's the other way around. The app is updated
so cleanly that it forgets scheduled alarms.

From what I know I think that an upgrade is an uninstall (removing the
alarms and the running process) and install. So besides old shortcuts
pointing to an activity that might not be available in the new app, or stuff
that your app created on the SD card (*), you should start from scratch, but
keep what's in /data/data/yourapp/files/ (your dbs for example).

I am happy to be corrected.

(*) There doesn't seem to be any lifecycle event that the app is going to be
uninstalled. Does anybody have a solution for cleaning up the SD card in
such a case?

 I suppose that when updating a application, the updater doesn't kill
 the process related to the application but only update the application

 kill the process or reboot the system.

 I think it is not very professionnal to tell user to deinstall and

You'll need to supply code that demonstrates the problem.  Given that this
behavior is nothing like the standard behavior of EditText anywhere else in
the system, here must be something in your code instigating it.

  Q1: Method appendWhere can only append ONE query condition? why it

 Read the javadoc
 (http://d.android.com/reference/android/database/sqlite/SQLiteQueryBui...)).

 Append a chunk to the WHERE clause of the query. All chunks appended
 are surrounded by parenthesis and ANDed with the selection passed to
 query(SQLiteDatabase, String[], String, String[], String, String,
 String). The final WHERE clause looks like: WHERE (append chunk
 1append chunk2) AND (query() selection parameter)

 So the behavior you are seeing is exactly what's described. If you
 want to AND several conditions using appendWhere, you must put the AND
 in each chunk.

[android-developers] OAuth on Android

[Matthias]

Hey guys,

I have recently been working on an OAuth library that has been
designed to play well with Apache HttpComponents 4 (and thus, Android
of course). If you're looking for a straight forward way to do client-
side OAuth on Android, check it out (literally) here:
http://code.google.com/p/oauth-signpost

I'd like to get feedback / suggestions / contributions from my fellow
Android developers (that would be you!).

Cheers,
Matthias

PS: there is also a slightly opinionated (hence missing on the project
homepage) rationale for why I started this project on my blog:

[android-developers] RelativeLayout with vertical center positioning problem

[elDoudou]

Hello.

I've been fighting for hours now, and still do not understand what I'm
missing. Sorry for posting only text, since I cannot attach an image
to this post.

I have an activity which uses an XML layout made of a top-level
RelativeLayout composed of 3 TextViews (see the XML at the end of the
post):

 - the first one (id=leftText, =green) with a green background is
intended to have its left border aligned with the left's of the screen
(i.e. on the left) and always visible, i.e. never pushed out of the
screen on the far left especially because of the second TextView (with
id=centralText) text length. Ideally, this TextView should be centered
vertically in its layout.
 - the third one (id=rightText, =blue) with a blue background is
intended to have its right border aligned with the right border of the
screen (i.e. on the right) and always be visible and not pushed out of
the screen on the far right (same remark as for the first TextView).
Ideally, this TextView should be centered vertically in its layout.
 - the second one (id=centralText, =red) with the red background is
intended to be between the first and third TextViews. It contains some
lenghty textual contents which spans multiple lines.

My problem is that I cannot manage the first (green) and third(blue)
TextViews to be centered vertically. I use the
android:layout_centerVertical=true attribute on both views on that
purpose, but this does not generate the expected right result: the two
TextViews seem to stretch the RelativeLayout height and are aligned to
the bottom of this layout. I get:


|  | red | |
|  | red | |
|  | red | |
|   |
 - 
| green |   | blue |


If I do not use this layout_centerVertical attribute, I get the
expected (which is not what I want):


| green | red | blue |
 - ---
|  | red ||
|  | red ||
---

I use the RelativeLayout because I want the blue (=third) TextView to
be on the right and always visible, whatever the length of the red
(=second) TextView. Hence, I need to declare it first in the
RelativeLayout. It seems that the RelativeLayout drawing does not take
properly into account the red TextView height in order to center
vertically the blue and green TextViews.

I am open to any suggestion to match my requirements and have the
following rendering:


|  | red | |
 - 
| green | red | blue |
 - ---
|  | red | |


Thank you so much for your time. Regards,
Édouard

Here is the standalone source code of the XML layout, so that you can
reproduce the problem:

?xml version=1.0 encoding=utf-8?

I too am having this exact same problem. It seems to be related to

In terms of developing on linux, this release is a backward step - its

I may have to revert back to the previous release, if that is indeed

[android-developers] Re: 'Take a picture' intent on 1.5 - anybody please? ;)

[BoD]

I'm really sorry to insist :) It's just that I didn't find a
definitive answer anywhere so I was really hoping somebody from Google
could quickly answer.

Is there another intent to use or a parameter to the
ACTION_IMAGE_CAPTURE one, to simply take a full-sized picture (should
be 2048x1536 on the adp1)?

I'd really like to know, because - correct me if I'm wrong - if the
answer is that it's not currently possible, I'm gonna have to
implement my own little 'Camera'-like app just to do that...

Thanks a lot.

  I tried the following piece of code to take a picture on 1.5:

  It works but the resulting image is 512x384 (on the ADP1).

  The doc says If the EXTRA_OUTPUT is not present, then a small sized
  image is returned as a Bitmap object in the extra field. If the
  EXTRA_OUTPUT is present, then the full-sized image will be written to
  the Uri value of EXTRA_OUTPUT.

  But 512x384 looks rather 'small-sized' to me!

  So what is the correct way to get the full-sized version?

[android-developers] Request for remote logs

[chris]

Hi , i just created this issue but since it's not clear if the issue
management is used or not , i'll put it again here
http://code.google.com/p/android/issues/detail?id=2589

What i find really frustrating is that our users seems unable to
report the issues they are having with any usefull informations.
Most of the time , all we have when we have something is a useless
Not working or Crashed comment.

What i would like to see is an automated crash report that would send
the RunTimexception  stacktrace to the market and a way for the
developpers to have acces to them.
This would give us some ideas of what going wrong with our
applications and let us fix it.(and give us an idea of how stable
really is our application on the Field.

[android-developers] how to add app to apps list

[birdy]

Hi all;

After build the cupcake, I can find many apps' .apk files in folder:
\out\target\product\generic\obj\APPS\xxx_intermediates. But only 12
apps put in apps list (alarclock, browser, calender, camcoder...
etc).
How can I add an app (ex. ApiDemos) to the app list and then I can run
it?
What is the purpose of xxx.apk.unaligned and xxx.apk.unsigned ?

Use other activities to avoid the need for so many tabs. Or, as the

a ViewFlipper.

 Another issue is the ListView widget. It's not a list view at all.

And your definition of list view is...what, exactly? It sure seems to
fit the definition of a list view from every GUI toolkit I've ever
used, and that stems back an awfully long time.

 settings. I do commit every single edit() like suggested. But a lot of
 users are still reporting that they lose settings. I don't know why
 but it happens some times. :( (I have worked with my app for 2 months
 now and have never lost the settings)

It will be difficult to fix the bug without a repeatable scenario.

 To sum up I don't like the suggestion using Sqlite because I would
 just ignore a bug which is obviously there but no one knows what it
 really is.

If you can come up with a repeatable scenario for the SharedPreferences
damage, post an issue to http://b.android.com with a project and
instructions for causing the problem.

Otherwise, if I were in your shoes, I would switch to some other means
(e.g., SQLite) of storing the data you are storing in SharedPreferences,
simply to make your users happy.

 Ok but i have problem with the startActivity method.
 
 I created a class ScreenGet witch extends Actity and override

 I write a function main to launch it :

This is not Android code. public static void main() is not an entry

 I supposed when I run it, it launch my activity , but i have got the

This is not Android. This is desktop Java. There is no C:\ drive and no

[android-developers] Low Memory: No more background

[balakrishna...@gmail.com]

Hi,

I am working on openGles with seven images displayed on the screen. I
am translating the position of these seven images on a button click
so
it is drawing every time it seems.
But, after sometime all the images are getting disappeared then I've
checked in the logcat
I found this :ActivityManager(52): Low Memory: No more background
processes.

I heard animating bitmaps via OpenGL may give similar problems.

Any suggestions would be appreciated.


Thanks,

[android-developers] R.drawable.list_selector_background doesn't yield in orange

[gsmd]

Ok, here's a simple 'helloorange' activity:
--
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView tv = new TextView(this);
tv.setText(some text);
tv.setBackgroundDrawable(getResources().getDrawable
(android.R.drawable.list_selector_background));
setContentView(tv);
}
--
When running this, the background doesn't change it's color. When I
change to android.R.drawable.btn_default, it works.
So, how do I apply orange background drawable to a TextView at
runtime?

TIA.

[android-developers] Text getting cut-off in a list view

[Gyan]

I have a list of text views in my screen. The text in one of the list item
gets cut-off on the right side. There is no padding attached in the layout
and there are no over-lapping layouts. But when i focus that particular list
item the text view is re-drawn and re-positioned to give me uncut text. This
happens inconsistently.

Is this an existing issue with the framework??

[android-developers] Unable to remove default launching of an application.

[Guillaume Perrot]

Example:
I have a button which starts an activity with GET_CONTENT audio/*
I have a menu with choices: Music Track or Sound Recorder and a
checkbox.
I check the box, it tells me that I can clear the setting in
Application - Manage Applications.
I launch the Music Track with the box checked.
I go to the application settings, but the clear defaults button is
always enabled.
It was already the case with 1.1 SDK, 1.5 does not help (tested on
emulator 1.5 AND ADP1 with 1.5 recovery image).

I also tested the allowClearUserData flag but it seems we cannot clear
anything but the cache (for the webview ?).

Nope.

Try this.
-Create a mutable bitmap the size of the screen. Save this bitmap as a
variable of your instance.
-Create a Canvas from this bitmap  (i think you can 'cache' it, save
this canvas as a variable of your instance).
-Draw your touches into this canvas.

Then in the 'onDraw(Canvas screenCanvas)' draw the mutable bitmap into
the screenCanvas.

Is there any place for official Android DTD files for the Manifest /

If yes, Where could I find them?

If no: Wyy does Google / Android not provide them?

[android-developers] Do application updates put your app back to the top of the list on the By Date tab in the android market?

[jcook2004]

I have an app on the android market and when I release an update, the
application does *not* goto the top of the app list on the by date
tab. But I notice that this isnt the case for all apps - infact just
today I noticed an app that was published months ago but updated w/ to
a new version appearing on the top of the list. What gives? Is there
some special process devs have to do to get their app update to the
top of the list on the By Date tab? Are they unpublishing/republishing
their app at every version update? Spill the beans :)


Thanks!

[android-developers] Issue with activities

[Tushar]

Hi,
I writing a small application on android 1.1 . This application when
launched from application menu starts with Activity1 . Using some UI
Activity1 launches Activity2 which finally launches Activity3 after
some user action.
When Press Home button and relaunch my application Activity1 get
launched.
But now if try to launch Activity2 , instead of Activity2 , Activity3
comes to foreground with old state.  Now if I go back to Activity1 by
pressing back button and then try to launch Activity2 it works fine.

What could be reason of Activity3 coming in to foreground instead of
Activity2 in second scenario ?

I have set Activity1 's launch mode as singleInstance, where as
Activity2/Activity3 are using default settings.

Tushar

You can be notified when select dedicated hardware keys are pressed:

ACTION_CAMERA_BUTTON
ACTION_MEDIA_BUTTON

http://developer.android.com/reference/android/content/Intent.html

Bear in mind that those keys are probably being put to other uses (e.g.,
activating the camera).

                 Float lon = cursor.getFloat(loncol);

 This should work, because I get the filename,  or is this a total
 wrong approach?

[android-developers] How to implement a button in a widget

[6real]

Dear all,

I try to create a widget and I am now wondering how to be able to put
a button on my widget and set its onClickListener.

It seems that we are limited to the RemoteViews... OK I can deal with
that (but this is a limitat to me) but I'd like to add a button where
the user can request an update on the data displayed in the widget. (I
get some info on the web but the user only needs to request an update,
I can't defined an automatique update, it's useless for my app)

I'm sure we can do that since there is an example with a player and
obviously with a PLAY/PAUSE button.

I was looking for in the remoteViews API btu without finding
anything...

Can you please give me the direction where to find the way of doing...
Thanks a lot for your help

[android-developers] Re: Questions on Tab (TabWidget) Width

[Lewis Z.]

Mark, thanks for the idea. I also implemented a similar stuff like
your ViewFlipper for other OS.

A list view can be as simple as one column list but can be as
complicate as a spreadsheet. I think a good widget should be easily
extensible/expansible. For example, the options menu is well thought.
You can limit the menu to six items. But when one needs more, it
automatically gives you an expanded menu. This is a little bit off my
original topic.

 Use other activities to avoid the need for so many tabs. Or, as the
 previous poster suggested, roll your own tab-like system, perhaps using
 a ViewFlipper.

  Another issue is the ListView widget. It's not a list view at all.

 And your definition of list view is...what, exactly? It sure seems to
 fit the definition of a list view from every GUI toolkit I've ever
 used, and that stems back an awfully long time.

[android-developers] TextView Hanging Indent?

[nEx.Software]

Is there a way to do like a hanging-indent in the standard TextvView?
Basically, I have an image that I am trying not to overlap, but I want
the text to be as close as possible to that image. I think a hanging
indent would be perfect for this but am not sure that this is possible
in the standard textview. I'm using this in an AppWidget, which is why
I am insisting on a standard TextView. Any ideas? thanks in advance.

[android-developers] Android 1.5 - crash during drawing of multiline TextView

[Mike]

I have a problem with Android 1.5 (problem that didn't appear in 1.1
and earlier):

This TextView is in RelativeLayout:
TextView android:id=@+id/list_item_name
android:layout_width=wrap_content
android:layout_height=wrap_content
android:text=Some Text
android:textColor=@color/black
android:layout_toRightOf=@id/list_item_marker
android:layout_marginLeft=8dip
android:layout_marginTop=5dip
android:textSize=@dimen/ts_item_top
android:paddingRight=70dip
/

Layout is filled and used inside ListView programmatically.

Whenever I have text that should be wrapped to multiple lines, this

How deep and complicated is your view hierarchy? With Android 1.5, I get
the sense that StackOverflowError will be triggered by a too-complex set
of views, particularly in terms of depth. You can use hierarchyviewer
(in the tools/ of your SDK) to see how many layers you have -- if you're
in double digits on the deepest branch, you might need to find ways to
simplify the UI.

It was already the case in 1.0 and 1.1 but because of new features

This means that the app was almost overflowing anyway.

[android-developers] Re: help: button.setBackgroundColor

[Romain Guy]

Don't call setBackgroundColor(). It simply replaces the button's
background with a solid color. If you want to keep the button look but
give it a new set of colors, you will have to grab the original assets
from the source code and modify them in a graphics editing tool.
Alternatively you can play with ColorFilters.

[android-developers] Video with MediaRecorder

[Anders Nilsson Plymoth]

Hi,

Does anyone know how to use the MediaRecorder to API to capture video?

I am writing an application where I want to be able to capture video. I am
trying to use the MediaRecorder API in 1.5, which is supposed to support
video capture. However, there are no examples in the documentation on how to
use this API for video (only for audio, and that works perfect). Basically
what I do is the following:

final MediaRecorder recorder = new MediaRecorder();
final String filePath;



recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
recorder.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP);
recorder.setOutputFile(filePath);
recorder.prepare();
recorder.start();

This gives me the following error:
E/CameraInput(   37): No surface is available for display
E/MediaRecorder( 7609): prepare failed: -2147483648

OK, so I have to have a surface to preview the video? Could be useful I
guess, but not something I really need.

Could I use the VideoView widget for this, or is that only for playback?

Or am I supposed to use a SurfaceView to preview the video? I saw someone
use that to capture images, but they used android.hardware.Camera to open
the camera and capture a frame, and did not use MediaRecorder.

Does anyone have any idea on how to capture video, or even better have some
example code?

Thanks,

[android-developers] Re: How to implement a button in a widget

[Jeff Sharkey]

Sure, this is easy to do.  If you have a Button in your target layout
passed to new RemoteViews(), you can call
RemoteViews.setOnClickPendingIntent() to trigger firing of the given
PendingIntent when people click on your button.  You could also use
any View, not just Button.

Here's how the Music widget is connecting up its buttons:

 Dear all,

 I try to create a widget and I am now wondering how to be able to put
 a button on my widget and set its onClickListener.

 It seems that we are limited to the RemoteViews... OK I can deal with
 that (but this is a limitat to me) but I'd like to add a button where
 the user can request an update on the data displayed in the widget. (I
 get some info on the web but the user only needs to request an update,
 I can't defined an automatique update, it's useless for my app)

 I'm sure we can do that since there is an example with a player and
 obviously with a PLAY/PAUSE button.

 I was looking for in the remoteViews API btu without finding
 anything...

 Can you please give me the direction where to find the way of doing...
 Thanks a lot for your help

[android-developers] Re: R.drawable.list_selector_background doesn't yield in orange

[Jeff Sharkey]

So the list_selector_drawable is a stateful drawable, where it's
default state is black.  (This is why ListView unselected items are
transparent/black.)  The default button drawable is also stateful, but
it's default state is an unpressed button.

You could force it into a focused state using Drawable.setState()
before setting it to the background.

However, keep in mind that you probably don't want to have the
TextView always appear selected, as it might confuse users to see two
selected areas on screen at once.

You might instead try setting the TextView to be focusable, so the
background changes automatically whenever the user moves focus to the
TextView.

[android-developers] Re: 'Take a picture' intent on 1.5 - anybody please? ;)

[bra...@gmail.com]

Bod - as far as I know there is no intent just to snap a picture. What
you can do is call the camera intent to start the camera app itself
and use that to take your image then use the last URI it generated as
the source for whatever you want.

 Is there another intent to use or a parameter to the

 be 2048x1536 on the adp1)?

 I'd really like to know, because - correct me if I'm wrong - if the

Thanks a lot for your answer!
Well I'm guessing this means I have to instruct the user to press the
back button after they took the picture (to go back to my own
activity), which is not ideal...

It's too bad cause the ACTION_IMAGE_CAPTURE one is exactly what I want
- except the result image is low res :(

delete app.apk from g1
2. export app.apk unsigned, install on g1 1.1  ... NOT POSSIBLE TO

[android-developers] MP3 to PCM 16 Bit

[Vimae]

With the new 1.5 now finally being released, I'm trying to give my app
a second go.

I currently have a service where you can stream your music library
from the web. However, each stream has to be authenticated with a
cookie or the server returns a 500 error, so the standard MediaPlayer
will not work, because I cannot pass a cookie with the Uri!

I noticed that the API now has an AudioTrack class within
android.media. It can take a raw stream of PCM 16 BIT. I was wondering
if anyone has any tips or ideas on progmatically transcoding MP3
stream to PCM 16 for playing through.

You could have a local proxy in your app that does that for you.

You would have to find an mp3 decoder to include in your app.
Using one written in Java would perform poorly, and using a native
one would require writing some JNI code and passing data back
and forth. The proxy approach might be easier.

The install process cannot change the signing key of an app.

If you push an apk with a debug key (which is what happens when you
run from eclipse), you cannot install a signed apk directly. You need
to uninstall the debug version first. Works the other way too: if you
install a signed apk, you cannot install a debug version from eclipse.

You cannot push a non-signed apk at all iirc. It has to be signed
either by the eclipse/ant debug key or by you manually.

[android-developers] Re: R.drawable.list_selector_background doesn't yield in orange

[alex]

Thanks, Jeff.
When user selects a TextView it 'slips' (which is indicated by
background color change) and the user is expected to select(tap)
another view then. Not every tap should lead to the first view losing
'focus'. That's the motivation behind setting background drawable
programmatically.
Back to the question.
--
Drawable bg = getResources().getDrawable
(android.R.drawable.list_selector_background);
bg.setState(new int[]{android.R.attr.state_pressed,
android.R.attr.state_focused});
tv.setBackgroundDrawable(bg);
--
This (and any of those attributes set alone) doesn't change anything.
Do I still get it wrong?

  So, how do I apply orange background drawable to a TextView at
  runtime?

  TIA.

[android-developers] Re: Video with MediaRecorder

[Dave Sparks]

You need to call setPreviewDisplay() and pass in a SurfaceView before
you call prepare().

 Hi,

 Does anyone know how to use the MediaRecorder to API to capture video?

 I am writing an application where I want to be able to capture video. I am
 trying to use the MediaRecorder API in 1.5, which is supposed to support
 video capture. However, there are no examples in the documentation on how to
 use this API for video (only for audio, and that works perfect). Basically
 what I do is the following:

 final MediaRecorder recorder = new MediaRecorder();
 final String filePath;

 

 recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
 recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
 recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
 recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
 recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
 recorder.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP);
 recorder.setOutputFile(filePath);
 recorder.prepare();
 recorder.start();

 This gives me the following error:
 E/CameraInput(   37): No surface is available for display
 E/MediaRecorder( 7609): prepare failed: -2147483648

 OK, so I have to have a surface to preview the video? Could be useful I
 guess, but not something I really need.

 Could I use the VideoView widget for this, or is that only for playback?

 Or am I supposed to use a SurfaceView to preview the video? I saw someone
 use that to capture images, but they used android.hardware.Camera to open
 the camera and capture a frame, and did not use MediaRecorder.

 Does anyone have any idea on how to capture video, or even better have some
 example code?

 Thanks,
 Anders

[android-developers] Re: ListView checked state wrongly shared between 2 views when reorienting screen

Yes they do, but is that wrong? I thought it was ok to have multiple
views with the same id.  They are part of 2 different activities that
share a common layout.

[android-developers] Re: R.drawable.list_selector_background doesn't yield in orange

[Jeff Sharkey]

 When user selects a TextView it 'slips' (which is indicated by
 background color change) and the user is expected to select(tap)
 another view then. Not every tap should lead to the first view losing
 'focus'. That's the motivation behind setting background drawable
 programmatically.

Ouch, this is actually more of a touch mode question.  When the device
goes into touch mode, there isn't a visible concept of focus in
ListViews (when you scroll the list, any highlighted item reverts
back).

You might be looking for android:focusableInTouchMode, but this isn't
used many places on the platform.

[android-developers] Activity state on pressing Back and Home button on the screen

[karthikr]

Hi Guys,

Whenever I press the home button when Im in the root task of my
application and when I click on the icon of my app again the state of
my task (activity) is retained, but when i press the back button on
the emulator and when I open my application its state is not retained.
I want the state to be retained in both the scenarios.

In the mnifest I have given the below entries,

android:alwaysRetainTaskState=true  for the root activity

android:launchMode=singleTask for the application

Regards,
R.Karthik

The back button means close up this activity, and so state is not
supposed to be retained.

 I want the state to be retained in both the scenarios.

Implement onDestroy() and persist your state to a flat file or SQLite
database or something.

[android-developers] Re: ListView checked state wrongly shared between 2 views when reorienting screen

[Toph]

Ok that prompts a few questions:
1) Can you elaborate on your last sentence: But that's true within an
activity only.  Are you saying that the identifier is the id plus the
activity? I have 2 different activities (on 2 tabs, actually).

2) How do you share a layout and use it multiple times, then?  If the
id is set in XML, and you have multiple instances, won't they save and
restore state incorrectly, then?

3) What about the items within a ListView?  Don't the all have the
same id(s)? Wouldn't this cause a problem when saving their state? Or
does the ListView do something magic to prevent such a problem?

On May 7, 1:54 am, Romain Guy romain...@google.com wrote:
 It's ok except when you need the views to save theirstate. The id is
 what identifies views when theirstateis saved so the toolkit simply
 think that your two list views are the same. But that's true within an

[android-developers] Copy My Location Functionality efficiently?

[Hunter Peress]

Hi. I'm looking to do a single location update as efficiently as
possible, currently, I'm doing:

requestLocationUpdates (getBestProvider(criteria, true), 0,0,
listener);

and then in the callback:
onLocationChanged(Location) {
  removeUpdates (listener)
}

The idea is to do 1 high priority location request, then immediately
end updates. Anyone see any downfalls with this?
