[android-developers] Re: Why there is an error when I doing unit test with ActivityInstrumentationTestCase2?
Hi Dianne,
I have tried to annotate the test method with UiThreadTest, but still
it doesn't work, the trace log is:
java.lang.RuntimeException: This method can not be called from the
main application thread
at android.app.Instrumentation.validateNotAppThread

So what's the problem? And is there any other method I can use to
perform a call on UI thread?

[android-developers] Re: Why there is an error when I doing unit test with ActivityInstrumentationTestCase2?
I have found the root cause of this problem.
That's because of getInstrumentation().waitForIdleSync()
I have seen someone else use waitForIdleSync() after UI action, I want
to know if it is necessary, and in which case we need to call this
method?
If we want to call it, how do we call it correctly?

[android-developers] Having a TextView auto complete with SearchSuggestions
Hi There, I have been successful in copying the APIDemo search example and I have search suggestions from search history popping up in the drop down search pane that appears at the top of the screen. However since search is the main function of my app, I have also created a start up screen with a search text box and "Go" button so that the user does not have to hit any keys to bring up the search prompt. So I hooked my search AutoCompleteTextView and "Go" button up to the same search framework, and it all works just fine, but I don't get the search suggestions on the AutoCompleteTextView. I had sort of been assuming that I could grab a list of search suggestions from SearchRecentSuggestions: SearchRecentSuggestions suggestions = new SearchRecentSuggestions( activity, SearchSuggestionSampleProvider.AUTHORITY, SearchSuggestionSampleProvider.MODE); but it seems I can only use that to add queries, not to get a list of them. That, I read, is all taken care of behind the scenes. I have read http://developer.android.com/reference/android/app/SearchManager.html which seems to hint that I can have recent search suggestions associated with my own search forms, but for the moment I am kind of stumped as to how to make them show up in the AutoCompleteTextView, or some other kind of TextView. Has anyone else managed to do this? i.e. have search suggestions pop up for something other than the special android search dialog? Many thanks in advance CHEERS> SAM --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: Why there is an error when I doing unit test with ActivityInstrumentationTestCase2?
Annotations have nothing to do with this, waitForIdleSync() has nothing to
do with this, it's just a basic aspect of Android that you can only call on
to UI objects from the thread running the UI. Use this:
http://developer.android.com/reference/android/app/Instrumentation.html#runOnMainSync%28java.lang.Runnable%29

Dan, a little larger window would be very useful. May be an extension by a week or two .. as the site opened on 24th late night only.

[android-developers] Re: Writing a Bitmap to a a outputstream
This is what i am doing can u please guide me as to what should be
corrected here,
On opening the file,
mBitmap = BitmapFactory.decodeStream(concontentresolver.openInputStream
(uri));
//to create a mutable bitmap out of it
mBitmap = Bitmap.createScaledBitmap(mBitmap,mBitmap.getwidth
(),mBitmap.getHeight(), true);
//also tried, for making the bitmap mutable
//mBitmap =mBitmap.copy(Config.ARGB_, true);
After i make changes to the bitmap i try to save it by,
OutputStream out = getContentResolver().openOutputStream(file);
if (type.equalsIgnoreCase("image/jpeg")) {
mBitmap.compress(Bitmap.CompressFormat.JPEG, 100, out);
} else {
mBitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
}
out.flush();
out.close();
But what i can see is that when i save it in a jpeg format there is a
loss in quality, and when i open a jpeg file for 3-4 time and save it,
the image is totally blurred. And the size of the
jpeg image file increases each time i save the image.
When i save it using Bitmap.CompressFormat.PNG the image is saved
properly, please guide me.
Is there any process that i have to do while opening a jpeg file and
writing it to a bitmap?

R.Karthik

[android-developers] Re: Why there is an error when I doing unit test with ActivityInstrumentationTestCase2?
Hi Dianne,
The following code can work well in my computer:
@UiThreadTest
public void testBikeButton(){
//click the bike button
bike_btn.performClick();
..
//I delete the following code, then it works
//getInstrumentation().waitForIdleSync();
..
}
So what I mean is that, in which case we need to use waitForIdleSync
(), and how to use this method?

[android-developers] Regarding streaming files
If i am using the streaming API's provided by the SDK that is mMediaPlayer.setDataSource(url); mMediaPlayer.prepareAsync(); If we are using this and if there are some max file transfer per connection rules set by the connection provider,does the SDK automatically take care of such issues where in different carriers have different file transfers per connection limit. What i really want to know is say i have an url for a song for streaming ,do i need to send it in chunks because of the limitations of the carrier settings.When is the program given in the following link useful otherwise? http://blog.pocketjourney.com/2008/04/04/tutorial-custom-media-streaming-for-androids-mediaplayer/ Thanks! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] APIs compatible with Skype & yahoo for Android
Hi All, I want to develope a application in Android just like Fring in which I can chat using skype & yahoo also. I found that using XMPP it is possible to connect the app with the gtalk server & we can chat on that. But I want the APIs for the Skype & Yahoo that are compatible with Android OS. I have done some R&D on that & found that skype APIs are available for windows, mac & linux development but there is not any description about Android OS. Can anyone give me any useful link or code sample which can be useful to me?

[android-developers] Spinner custom view bug
Good morning,
Found a little bug in Spinner widget when using a ImageView (or widget
that doesn't have a baseline) as view for Spinner.
Spinner source code:
@Override
public int getBaseline() {
View child = null;
if (getChildCount() > 0) {
child = getChildAt(0);
} else if (mAdapter != null && mAdapter.getCount() > 0) {
child = makeAndAddView(0);
// TODO: We should probably put the child in the recycler
}
if (child != null) {
return child.getTop() + child.getBaseline();
} else {
return -1;
}
}
ImageView doesn't have valid baseline, so when Spinner shows on device
the Spinner widget is drawn to low.
Overriding getBaseLine() in ImageView and returning 15 seem to
positioning the Spinner widget correctly.
Does anybody know how i can calculate the value that should be
returned by getBaseLine()?
Kind regards,
Twan

[android-developers] Application run on an emulator cannot fix the screen size of a real device
Hi guys, My application has an activity to display a textview on the screen, and it ran well on the emulator (it can fulfill the whole screen). However, when I try to run it on the device with the resolution 640x480, my application cannot fix the whole screen of this device (just keep the size as of 480x320). I tried to set the fullscreen flag to hide the title bar, this is implemented in 'onCreate()' method of the activity as below: this.getWindow().setFlags (WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); And I also set the layout for .xml file like this: http://schemas.android.com/apk/res/ android" android:id="@+id/root" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@drawable/black"> I don't know why my application cannot fulfill the whole screen as expected.

[android-developers] Re: How to use the RotationMatrix, actually how to get it
To deep copy an array, you can use System.arraycopy(..)
http://developer.android.com/reference/java/lang/System.html#arraycopy%28java.lang.Object,%20int,%20java.lang.Object,%20int,%20int%29
System.arraycopy(b, 0, a, 0, 3);
but for a float array of length 3, you can simply write
a[0]=b[0];
a[1]=b[1];
a[2]=b[2];
or
for (i=0; i<3; i++) a[i] = b[i];
I've never tried to profile which of the 3 ways is actually the
fastest on a real Android device. If someone has the time, please try
all 3 in a tight loop and report back :-)
(there is also
for(i=3; i-->0;) a[i] = b[i];
which may be even faster?)
Note: all assume that you have initialized a already beforehand,
a = new float[3];

[android-developers] Re: bluetooth use in android
Dianne, I was very happy to see Stefano's contribution as I wanted to get a head start on developing some ideas requiring interfacing Android to hardware via bluetooth. Yes I'm very aware it can break at any time. I am really looking forward to the official Android Bluetooth APIs for DUN, SPP etc and hope the wait was worth it. Can you comment on what the ETA on that is? Joe. PS: Wondering (half jokingly) will there ever be Zigbee support in Android phones :-) On Aug 23, 6:43 pm, Dianne Hackborn wrote: > Hi Stefano, I know you already say this in your site, but just to be extra > clear -- the code here is accessing private APIs, so we make no guarantees > about it working in future versions of the platform.

[android-developers] How to manage service lifecycle when device kills it due to low memory
Hi! I have a service that polls for data. To indicate this to the user I have a persistent notification in the statusbar. In some cases when the device goes low on memory it destroys the service but OnDestroy is not called. Later when there is available memory OnCreate is called. Is this normal behavior? I had hoped that OnDestroy would be called to I could remove the notification in the statusbar. Now the user thinks that the service is still running, while it has been stopped by the OS. In order to restart the polling how do I know that the OnCreate is really a restart event and not first time creation of the service? I thought about checking for the presence of the notification in the statusbar, but I couldn't find a API to check if a notification was showing or not. I have not tried "SetForeground" on the service, since the service isn't that important to the user, but maybe that would minimize the problem... -Christer --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: SingleTask...
hm... okay, so I check for null in my onCreate() method.
public void onCreate(Bundle savedInstanceData) {
if (savedInstanceData == null) {
// do everything I did before.
// show splash screen
super.onCreate(savedInstanceState);
}
}
However, now if I'm in my app, I click on "home", and then click on
the icon again, it behaves as expected, it simply brings the app back
in the expected state. If I hit "back" and then click on the icon
again, it behaves like I launched a brand new app - shows the splash
screen, etc...

Could someone on the Android graphics team comment on whether people should code around this or if people should ignore it because it has a good chance of being changed in a 1.5 update?

The 1.5 version of the OpenGL example at http://www.pragprog.com/titles/eband/source_code exhibits this issue, but I hate to put in hacks for short-term problems because they cloud the examples and may be inefficient or even stop working in the future.

[android-developers] Re: Running listeners in separate threads (=> not in the main thread)
Listeners are called back in the thread of the instance for which they registered. Usually this means that listeners' callback methods are run in the main GUI thread. If you want to do 'heavy' work when a callback to a listener is issued, you have to do it yourself. Your listener should start/resume an AsyncTask (or Future task created from ExecutorService), return immediately and your AsyncTask should do the 'heavy work and post the result back to the main GUI thread.

[android-developers] Re: Adding Threshold to Bitmap Images
You can create a color-filter with color-matrix that will give the effect of 'Threshold'. To get the correct values for the color-matrix, i used this web-site: http://www.quasimondo.com/archives/000565.php and the sources you can find here when you click on "Download the source files here." This will download a zip file. Open up ColorMatrix.as and look for the method 'threshold'. It should be easy to translate this into Java.

[android-developers] Problem to communicate with a service from an application
Hi, i have some problem to communicate with a service from an Android
application.
The service is in a first package "package com.myService" and the application
in another on "package com.myApplication".
My service work and start well but my next step is to add an AIDL interface to
external applications.
I have tried to follow the recomandation described here :
http://developer.android.com/guide/developing/tools/aidl.html, but i have still
the following error (given in the log service):
W/ActivityManager( 568): Unable to start service Intent {
action=com.MyApplication.IBootstrapService }: not found
My AIDL defined in both packages is :
interface IMyservice
{
String GetVal1();
String GetVal2();
// Get the status of the public API
int getStatus();
}
About the AndroidManifest.xml files :
>From the service :
package="com.Myservice"
android:versionCode="1"
android:versionName="1.0">
>From the application :
package="com.MyApplication"
android:versionCode="1"
android:versionName="1.0">
Why in each example, there is an application AND a service in the same package
? Is is mandatory to do this ?

[android-developers] Re: Writing a Bitmap to a a outputstream
If you write a JPG, information is written with a loss. Always. Even

losses in image-data will compound.
Why not use the PNG format? Why do you need to write a JPG?

When i read the docs for SharedPreferences it seemed to suggest that, but i just wanted to confirm (the word "shared" scares me :) ). tia. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] GL11 Implementation Issues
Regarding the support or lack of support for OpenGL ES 1.1. I know that officially the emulator and also the G1 device do not support OpenGL 1.1. And I suppose that officially, the SDK does support OpenGL 1.1 (the interface exists). Fact is that when GLSurfaceView creates an instance of a class that implements the GL interface, that class also implements the GL11 interface (this happens on both emulator and device). I suppose some of the functions in that class are implemented as empty stubs, or only prints some 'unsupported' log message. However, the fact is that the MSM7205 chip (ATI Imageon GPU) that is inside the G1, does support 'most' of the major features of OpenGL 1.1 standard. It supports GL_COMBINE modes, user defined clipping planes, etc... (I think also buffer objects) So when running on the G1 device I would expect that calling: gl.glTexEnvx( GL11.GL_TEXTURE_ENV, GL11.GL_TEXTURE_ENV_MODE, GL11.GL_COMBINE); Will pass through the interface and the drivers and reach H/W GPU and set the TEXTURE_ENV_MODE to COMBINE. But according to tests I've made it seems someone is intercepting that call on its way to the H/W GPU. Can anyone please clarify this issue? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: how can close other activity?
It is a conceptual problem which you are trying to solve with controling an activity from another activity. The Android platform tries to simplify UI development in a way that it defined a life cycle for activities. If you try to control an activity from another activity you change the current implemented approach. Which would add also much more complexity. For example when would be a main activity allowed to close another activity? I think you should be able to change the logic of your program without having the need to control another activity. -- Roman Baumgaertner Sr. SW Engineer-OSDC ·T· · ·Mobile· stick together The views, opinions and statements in this email are those of the author solely in their individual capacity, and do not necessarily represent those of T-Mobile USA, Inc.

[android-developers] Chinese name writen in Sim Contact appears to be blank
hi, All
I'm trying to write some contacts into sim contact.
ContentValues cv = new ContentValues();
cv.put("tag", "");
cv.put("number", "");
cv.put("newTag", "中文");
cv.put("newNumber", "12345678");
getContentResolver().insert(SIM_CONTACTS_URI, cv);
After you shut down the phone and check the sim contact inerted, the name "中文"
become blank.
Or, you setup the sim car into another phone, and check the contact, you will
also find that the Chinese name has gone.
Is there anyone encounters the same problem?
Thank you all.

[android-developers] Re: Writing a Bitmap to a a outputstream
That's what i'm doing with my app as well. And i have the same issue. As soon as your re-read a JPEG and save it again (modified or not), you will get loss of quality. There is no other way around it. In my app, i don't save over the original image. I do a 'save-as', more or less. At least the original image is preserved. In other words; i find the same problems that you find. As soon as i find out a way to solve these, i'll let you know :-) Updating gallery and thumbnails: Take a look at the MediaScannerConnection.

You will probably need an here, to associate some

Please read the documentation. As I said in my original post, this is for
when your activity gets killed while it is in the background. When you
press back, the default implementation is to finish() the activity so there
is no longer any instance data.

[android-developers] Re: How to manage service lifecycle when device kills it due to low memory
Not getting onDestroy() is normal, expected, and desired behavior as for all app components -- the kernel kills processes when it needs more memory, we don't rely on them being nice and cleaning up at their leisure. The current semantics for recovering from being killed are unfortunately as you describe. I actually just checked in a change for Eclair that improves this a lot, allowing you to much better control what happens after being killed, and detecting that you were killed when restarted. Until then, you'll need to take care to implement onCreate() to recover. As far as being foreground -- if you do indeed show a notification while running, then making yourself foreground is reasonable (since the user knows you are running, and can go through the notification to stop you), and will basically ensure that you aren't killed. Note though that another change in Eclair will be that setForeground() no longer does anything, and will be replaced with a new API that requires having a notification shown while being in the foreground state. (This is because numerous apps are now abusing setForeground() by just using it to avoid having their memory used when the system needs it, instead of to let the system know the user is actively aware of what they are doing and so shouldn't be killed.) It does sound a little odd to me that you say the service isn't important to the user, but you are posting a notification while it is running. If it isn't important to them, I would suggest it shouldn't be notifying them. ;) Another thing to think about -- if you are polling, ideally you wouldn't keep your service always running. Typically how people implement polling is by scheduling an alarm to start their service after the poll interval. Then if you get killed, you can always recover when the next alarm goes off. (You can either schedule a repeating alarm, or re-schedule your alarm in onStart(); you are guaranteed to not be killed except under severe circumstances while in onCreate() or onStart().)

There's no reason that they would change the deadline. The deadline has been set at the 31st since late May (as stated before). With that deadline posted, your app should be ready to hit the submit button on the 31st or sooner. Nothing changed, they're giving you a full week to hit the "Submit" button. - Dan On Tue, Aug 25, 2009 at 12:06 PM, Maps.Huge.Info (Maps API Guru) < cor...@gmail.com> wrote: > > I see no need to extend the deadline, it's been public since May 27th, > if you're not ready by now, you'll probably never be ready.

[android-developers] Re: ADC 2 Submission Site -- Now live
You are right.. yeah our app is more than ready.. but not everybody was expecting a one week window. Some do travel on business during working days and it happens to be a long weekend in the UK. And submissions from business involve a paid bunch of developers who don't work like hackers over weekends and around midnights. And this request is due to the window being too short to yield for contingencies (unlike what was initially announced). Thanks for your time and thinking from shoes of another person.

[android-developers] Android Camera : My photo is completely black :-/
Hi,
I am creating a little application where I use the Android Camera
class. Everything seems to work but the result is a black picture.
I think I forget to set a parameter.
Do you have any ideas on which parameter I must set up ?
The code:
public boolean takeIt() {
ImageCaptureCallback iccb = null;
try {
String filename = "photo.jpeg";
ContentValues values = new ContentValues();
values.put(Media.TITLE, filename);
values.put(Media.DESCRIPTION, "Image capture by
camera");
iccb = new ImageCaptureCallback(new
FileOutputStream(new File
(dataMgr.getRoot(), filename)));
} catch(Exception ex ){
ex.printStackTrace();
}
camera.takePicture(mShutterCallback, mPictureCallbackRaw, iccb);
return true;
}
If you need something else, just tell it ;p
Thanks,
D.

[android-developers] Re: ADC 2 Submission Site -- Now live
If the app was submitted to the Market in any form before August 1st, it's not eligible. If the app was first submitted in any form after August 1st, it is eligible. So if you submitted the first version to Market after 1 August, you may submit a revised version to the ADC2. - Dan On Tue, Aug 25, 2009 at 1:43 AM, Ehab Bassilli wrote: > Dan, > > Sorry to be a pain but what about upgraded versions of apps sumitted after > aug 1st? > > I.e. the new features and ui were available after aug 1st? > > Thanks > > On Aug 25, 2009 4:21 AM, "Dan Morrill" wrote: > > This is correct: upgraded versions of apps submitted to Market before 1 > August are ineligible; this includes UI upgrades. > - Dan > > On Mon, Aug 24, 2009 at 4:09 PM, mgpc wrote: > > > Hi > Ehab, > > The rules say... > > You received this message because you are subscribed to the Google Groups > "Android Developers" grou... > > > > > --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] How to get the duration of an audio resource using SoundPool
Hi, I have a scenario where I want to play several samples after each other. Sounds like a job for the SoundPool since they will re-occur and I want to keep them loaded. Below is a code snippet: SoundPool soundPool = new SoundPool(1, AudioManager.STREAM_MUSIC, 0); int mySampleId = soundPool.load(context, R.raw.mySample, 1); //Load a bunch of other samples here... AudioManager mgr = (AudioManager) context.getSystemService (Context.AUDIO_SERVICE); int streamVolume = mgr.getStreamVolume(AudioManager.STREAM_MUSIC); soundPool.play(mySampleId, streamVolume, streamVolume, 1, 0, 1f); The play() method of the SoundPool returns instantly so I want to be able to know how long to wait before starting to play the next sample. The MediaPlayer has a getDuration() method that would be conviniant in the SoundPool as well, i.e. to get the duration of a sound ID. Does anybody know how to get the duration of a sample fetched as a resource or do you have an alternative solution. Using a MediaPlayer instance feels a bit more heavy weight .

Is there a way to make Canvas.drawXXX replace the colours below rather than paint on top of them?

Does this value seem to be wrong or is the maximum sampling rate really this low? And if it is, how come? Since the CPU clock is 528 MHz, shouldn't it be possible to aquire much higher sampling rate? Is it a hardware problem or a software setting, and if the later - is it possible to get it higher? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] What's the meaning of the $ (dollar sign) in the backtrace?
Hi all, I wanted to understand what the $ sign and the number after a $ sign meant in a backtrace. For example, consider the following backtrace: at android.app.ActivityThread.access$2500(ActivityThread.java:115) at android.app.ActivityThread$H.handleMessage(ActivityThread.java: 1745) In the first line, what does the number 2500 refer to? In addition, I couldn't find the function "access" in ActivityThread.java, and line 115 is just the beginning of the class. Can anyone help clarify this?

} catch (MalformedURLException e) {
result = "\n1:" + e.toString();
}
if (url != null) {
try {
HttpURLConnection urlConn = (HttpURLConnection)
url.openConnection(); //使用HttpURLConnection打开连接
BufferedReader in = new BufferedReader(new InputStreamReader
(urlConn.getInputStream()));//为输出创建BufferedReader
String inputLine;
int lineCount = 0; // limit the lines for the example
while ((lineCount < 10) && ((inputLine = in.readLine()) !=
null)) { //读Response中的数据
lineCount++;
result += "\n" + inputLine;
}
in.close();
urlConn.disconnect();
} catch (IOException e) {
result = "\n2:" + e.toString();
}
} else {

[android-developers] Do the applications keep/manage their own SQLite databases (files)?
Hi All, Android includes a database engine (SQLite). In general, do the applications keep/manage their own databases (files) or is there a unifying database manager?

[android-developers] Time to first screen, boot-up time and app-start time?
Hi all, at the moment I am thinking about a new app and need some information to decide whether to develop on Android or an alternative OS. I am particularly interested in "time to first screen", "boot-up time", "time to first Audio" and "app-start" (can be any from the android market or even one of the pre-installed ones) time? Does anyone know a source or perhaps measured those numbers? Thanks very much for all your help!

[android-developers] OpenGL ES confusion
Hi All,
I am new to Android and OpenGL world.
I've created a new ap using openGL ES. ( I am not able to find a
option to send attachment of package to group, so that youi can see my
code and sugest me wherei made a mistake).
Android Simulator LCD size is 320 x 455 and i've set same size for
OpenGL Viewport.
But For creating visible rectangle i've to use vertices, which are of
very high value.
e.g.
int vertices[] = {
-2,-2,0,
-2,2,0,
2,2,0,
2,-2,0
};
why is it so, when screen size id 320 x 455??
Please clarify my this doubt that may solve my many other problems.
Regards,
Harish Haswani

Does it download .apk first and then install it?

[android-developers] Access to other appications
Currently, I tried to create an event of the Calendar application which is included in Android 1.1 by my own application developed by Android SDK. Originally, the class and functions of the Calendar can not be found. After I found the library of Calendar and put it to the classpath, there is no error anymore. However, the access still failed in runtime. It seems that the Calendar applications are prohibited to be accessed, isn't it? I considered of accessing the DB of Calendar app directly, but it seems that there is no way to access the DB of another application. Is there any solution to access the Calendar app by my own app? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
