[android-developers] Re: headset button
For wired headsets, you can use Intent.ACTION_MEDIA_BUTTON as mentioned in the other thread. This is how the built in media app does pause/play on wired headset button presses, and where I recommend that you hook in. For Bluetooth headsets, they do not work like you think. There is no 'button pressed event' sent by the headset. We don't know when the button is pressed. Instead the headset maps its buttons presses to commands depending on its state machine. We receive commands, not button presses from the headset.

[android-developers] Re: Leaked window in PreferenceActivity
I did search the forum but due to the low number of preferencescreen
example I couldn't find anything directly concerning both
preferenceactivity AND orientation. :-) I did state in my post I had
been reading the tuts on androidguys, unfortunately there is not a
'merged' example of both.
My stripped down version exhibits the same issue:
test.java:
public class test extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
@Override
public boolean onCreateOptionsMenu(Menu menu)
{
super.onCreateOptionsMenu(menu);
MenuItem mi;
mi = menu.add(0,0,0,Settings);
mi.setIcon(android.R.drawable.ic_menu_preferences);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item){
switch (item.getItemId()) {
case 0:
startActivityForResult(new
Intent(test.this,ShowSettings.class),
30);
return true;
}
return super.onOptionsItemSelected(item);
}
}
ShowSettings.java:
public class ShowSettings extends PreferenceActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.layout.settings);
}
}
settings.xml:

[android-developers] Re: Audio in the emulator...
Thanks for the advice,
I work on windows vista,
the audio backend found is:
winaudioWindows wave audio
But it doesn't work with audio-out and audio-in at the same time for me.
emulator: warning: opening audio output failed
audio-out works alone
I tested it with the sample provided with the sdk when reading ressources.
It doesn't when trying to read the sdcard.
the sdcard isn't readable in settings too, and it won't launch itself from
eclipse with the additionnal emulator command line option, but only from
cmd.exe with the arguments -sdcard sdimg.iso
However, the logcat says this repetitivly when I click on record with
audio-in:
D/AudioHardware 25: AudioStreamInGeneric::read0x40308160, 320 from fd

I finally found the sound recorder application you where talking about, I
haven't tested it yet, but the source code is 100* bigger than mine...

I think there was also some sample code in the SDK at one point. Maybe

to look for the source for the Sound Recorder application on

Hello,
I have been searching for some time and I can't find a detailled
tutorial on how to easily record and then read audio on the emulator
under eclipse. I have found these steps:
- You have to install a virtual sd card with mksdcard.exe 1024M
sdimg.iso
-then run the emulator : emulator.exe -sdcard
sdimg.iso//where sdimg.iso it is the path to
the sdcard
-then run adb.exe : adb push local_file sdcard/remote_file
-then you should put : uses-permission
android:name=android.permission.RECORD_AUDIO/uses-permission in
the androidmanifest.xml
-then there is some code to implement which should look like :
private void startRecord() {
recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC); //ok
so
I say audio source is the microphone, is it windows/linux microphone
on the emulator?
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(/sdcard/test.3gpp);
recorder.prepare();
recorder.start();
}
-then you should stop with : recorder.stop(); // at some point (I have
no idea when and where to decide to stop but I haven't searched yet)
-then you should play it.
I have also heard about :
http://code.google.com/intl/fr/android/reference/emulator.html#sdcard
in this page of the manual (~1/4 of the total scroll), there are some
informations about Emulator Startup Options, one of them is about
Media -audio backend
I couldn't find much about that backend thing, google didn't said much
about it. I still don't know if it's important to the audio recording
process.
The fact is all these steps are pretty blurry to me, and I believe I
am not the only android newbie trying to record some sound :)
Anyone knows where we can find a complete tutorial for dummies
teaching this feature?
Any help is of course greatly appreciated
Thanks.

No I was not using a debugger, just DDMS.
2009/2/1 EboMike ebom...@gmail.com
Guillaume, that kind of sounds like you're running with a debugger
attached... see somewhere in the middle of this long thread, it is
known that the system will leak memory when you run with a debugger
attached - mostly when exceptions are involved, and
BitmapFactory.decodeFile() always throws (and catches) an exception.
Do you get the same results when you run without a debugger? All my
memory woes have been fixed when I stopped using a debugger except
when necessary.

On Jan 31, 8:14 am, Guillaume Perrot guillaume.p...@gmail.com wrote:
There is bug in BitmapFactory memory allocation, there are tons of
threads in this mailing list dealing with that.
To sum up:
At a normal time when you create an object, the heap size is
automatically grown if not sufficient enough (there is an absolute
limit of 16MB per process though, you will crash if you exceed this).
But the bitmap factory allocates memory in a non Java way, it uses
native code to do that, and the heap growing process fails if not
enough memory in this case!
So even if you are far under the 16MB limit, if you are unlucky enough
to have the heap grown up for your image to be allocated, you will
have an OutOfMemoryError
Some guys claim that this crash can be avoided by catching this error
(catching an error instead of an exception is quite unusual by the
way)...

Hey gym,
1) You don't have to go that far. No need to close or reset anything,
simply run the app from within the emulator (obviously, you need to
update it via adb install -r or something if you changed it). It will
show up in the process list in the DDMS, but you'll see that it
doesn't have that cute bug next to it. You can still add the heap
watch to it, this will not affect anything. And you can always attach
the debugger later if you need to debug something -- if you have the
heap watch on too, you might be able to see a change in behavior as
soon as you attach it. In my test app that repeatedly called
BitmapFactory.decodeFile and/or threw an exception, I noticed an
immediate continual increase in memory usage until it OOMed.
2) You won't necessarily see any garbage collection until the VM
decides to collect. That's okay. It doesn't matter if your app takes
up 15MB without ever collecting garbage. But as soon as you do an
allocation that exceeds the amount of available RAM, the gc should
kick in and take out the trash. Basically, it's all good as long as
you don't OOM. If you OOM, something went wrong.
Please note the very beginning of this thread - there is a known
problem in the Gallery class, it never recycles its views. However, I
have an app that uses two Galleries, both of them using
BitmapFactory.decodeFile(). I've run it on my device, sometimes with
1000 entries in the Gallery and scrolling like crazy, and I've never
OOMed. If I have the debugger attached, I OOM pretty quickly.
3) Interesting. SHOULDN'T happen, the VM should automatically gc as
soon as you're running out of memory.
Are you doing anything funky with your Bitmap/Drawable objects? How do
you manage them?

I have noted the following discrepancies compared to the descriptions
here, using a similar, simple application which uses Gallery, and

1) EboMike, How exactly do I run the application without a debugger

new emulator from a DOS prompt (without Eclispe running) would be the
equivalent of not having a debugger attached.
When I do this, I get the same memory leak problem as I always did...
2) When I have the DDMS attached and running, the heap size doesn't
show any garbage collection (see below) going on for my gallery
application (unless I click on Cause GC)...
3) If I call System.GC() intermittently directly in my application
(calling this method alone, and not as part of a {gc() /
runFinalization() / gc()} sequence), this prevents OOM, and then I
can
see the GC altering the heap size (in DDMS).

If using EXTRA_TEXT, the MIME type should be text/ plain; otherwise it should be the MIME type of the data in EXTRA_STREAM.

[android-developers] Re: What determines Android Market popularity ranking
Has anyone figured out this magic formula? I have a app that has 15000 downloads, a rating of 4.38(600 ratings), but it is still less popular than a competing app with 1 downloads and a rating of 3.45. How is this possible? My guess is that it is related to the number of uninstalls but then the rating system is all wrong? I think I just have to make a new application with a similar name and start all over again since the app got a lot of uninstalls in the first version. But then I loose 600 ratings which could potentially be very important to have if the rating system changes... So please, Google employees, can you give us any hints on whether you are doing any changes to the rating system in the near future or give us any hints on how the list is decided? -Christer On Dec 18 2008, 3:44 pm, joshv jvanderb...@gmail.com wrote: I've posted this question to theMarkettechnical support forum and received no answer, so I will try here.

[android-developers] Re: What determines Android Market popularity ranking
There also seems to be a time aspect to it - newer apps seem to be favored in the ranking even if they have not as many downloads or ratings as an older one. As a suggestion to the Market team: it would be really nice to list the apps by multiple metrics. We already have date and this secret, magic popularity metric. Sometimes I just would like to see which are the most downloaded or most highly rated applications in a particular category.

[android-developers] Re: What determines Android Market popularity ranking
The active install % seems to be very highly rated in this magic formula right now. Which means any update you release will, by definition, kill your popularity. Personally, I'd rather focus on improving the app instead of gaming the system, but I agree it would be nice if the rating favored # of downloads a bit more.

According to the doc: http://code.google.com/android/reference/java/lang/Math.html#sin(double) you need to provide the angle in radians, where 2*Pi corresponds to 360 degrees (i.e. Pi/2 is 90 deg). http://en.wikipedia.org/wiki/Radian In Java, you can use the constant Math.PI for Pi.

[android-developers] No callback when list item is touched.

item is clicked with the trackball, it works fine, i.e. I can catch
the event and move on, though when I touch an item with my finger
there is no callback from the listener. The item does respond to the
touch, by turning orange for that moment.
Here is how I've setup the listener. This is within an Activity, not
a ListActivity.

Great - thank you. I'll remember to read the documentation next
time :)
I've pasted my code below in case anyone wants to borrow it: it keeps
polling for up-to-date and accurate GPS data, up to a maximum of 10
seconds. If by then the GPS data is old or not accurate enough, it
just returns false.
The code feels a bit dubious, but it seems to do the job.
Anna
long locationTime = location.getTime();
long currentTime = System.currentTimeMillis();
timeDifference = (currentTime - locationTime) / 1000;
float accuracy = location.getAccuracy();
int count = 0;
// Wait for accurate GPS data, up to a maximum of 10
seconds before
// throwing an error
while (((timeDifference 10) || (accuracy 20.0))
(count
20)) {
location =
locationmanager.getLastKnownLocation(gps);
locationTime = location.getTime();
currentTime = System.currentTimeMillis();
timeDifference = (currentTime - locationTime) /
1000;
accuracy = location.getAccuracy();
Log.d(LOG_TAG, getting up to date GPS data,

I'm noticing that sometimes my app is giving me an out-of-date

- it'd be good to warn the user about this.
It's possible to check the age of the data on the iPhone I believe, is

[android-developers] Re: Specific Design significance of Attribute Name Spaces in AndroidManifest Files.
There are two main reasons for this: 1. In a layout XML, your XML tree contains tags corresponding to classes to instantiate and the the attributes are parameters passed to those classes. Since this is sitting on top of an OO model, the specific class corresponding to the tag will have an arbitrary number of base classes, implemented by an arbitrary number of authors. Yet all of those classes will be pulling their arguments out of the single set of attributes, so namespaces allow us to avoid any conflicts as the different implementations change in version. 2. This allows for a number of key optimizations we do to be able to much more efficiently parse these XML resources, without the requiring that the tools have DTD descriptions (and actually more than full) of every kind of XML file you create. These optimizations come into play when the resource compiler sees an attribute in a sub-namespace of http://schemas.android.com/apk/res/..., and include things like: - The corresponding resource ID of the attribute is embedded in the compiled XML, so it can be find with simple integer comparisons. - Multiple such attributes are sorted in order of their resource IDs, so obtainStyledAttributes() can be performed as an O(N) operation (this is the reason for the funky way that API works). - The resource compiler uses the type information associated with the attribute resource to pre-parse its value, such as converting color and integer strings to 4-byte ints, converting enums and flags to their final int value, resolving references to resources or attributes to their associated resource identifier, etc. Without these things, there is just no way we could have used generic XML files for layouts and such and achieved sufficient performance; we would have had to take a more traditional approach of converting the resource source files (which could still be XML) into some custom specific binary blob for that specific resource type. With what we have now, the full XML data is parsed on the device, just using our own special binary XML format. Hope that helps!

[android-developers] Re: How good to use intents with an application to communcate and modularise it
On Sat, Jan 31, 2009 at 8:12 PM, Raja Nagendra Kumar nagendra.r...@gmail.com wrote: In the contex of one each activity approach, we the following advantages - Go with just one activity for the enitre application, hence no need to think of managing many activities life cycle - AndroidManifest would have only one configuration - Switch the view by way of creating views as it demands and use them - if each view needs a context to create it self properly, pass the paratmers to the constructor of the view, this would also enhance compile checks and enable maintnace as opposed to intent key value pair approach. You missed the disadvantages, the main one being that you are then responsible for keeping track of the full state of your application so that it can be recreated when the user returns to it after its process has been killing or changes the configuration it is running in by for example rotating the screen. This can actually become a significant amount of effort to do well, since you need to limit as much as possible the up-front work you need to do to get your UI re-created in whatever state it should be in. Closure comparision to J2ME is Canvas which has lifecycle, however many frameworks recommend one instance of canvas only..

[android-developers] Re: No callback when list item is touched.
No, I am printing a log entry just before I call viewItem(), and I wasn't seeing that log statement when touching the item. Though I think I have found the problem. I narrowed it down to my custom adapter that extends ArrayAdapter. In my adapter I call the overloaded ArrayAdapter constructor: public ArrayAdapter(Contexthttp://code.google.com/android/reference/android/content/Context.htmlcontext, int resource, int textViewResourceId, List http://code.google.com/android/reference/java/util/List.htmlT objects) I use this so I can define a standalone XML layout (resource) to use for each item in the list. Then when overriding getView(), I call super.getView() to get that layout, set the elements based on the object at that position, then return the layout for that row. The problem occurs when my layout contains a Button or ButtonView element. After taking out the Button (which I wanted for a speficic action to be taken), the listener is now getting a callback when touching the item. Is this a bug or am I not doing something correctly? Below is an XML layout for my rows. Simply commenting out the Button element fixed the problem. ?xml version=1.0 encoding=utf-8?

[android-developers] ImageButton resizes within TableLayout -- How do i fix?
*Scenario* I'm attempting to host Image Buttons with a descriptor TextView below each button. To do this elegantly, I decided to use a TableLayout. The resulting image should look something like like: [img1][img2] [img3] hi please send this exit As you can see above, each image is properly centered within its cell and some text is displayed below. *Issue* Unfortunately, if the descriptive text is longer than the ImageButton is wide, then the ImageButton associated with that text is stretched. See below: [img1] [ img2 ] [img3] hi please send this exit *Failed Attempts* Setting Height Width: I've already tried to fix this by setting layout_width layout_height for each element, but within a TableLayout it does not seem to work (these seem to be ignored for the stretched item). Also I thought I could nest each row within a LinearLayout (vertical orientation) but for some reason the layout file will not render if an ImageButton is nested within a TableLayout TableRow LinearLayout. *Example Code* You can use this example XML to reproduce the issue at hand. TableLayout android:layout_width=fill_parent android:layout_height=wrap_content android:layout_gravity=center_horizontal TableRow android:gravity=center_horizontal android:layout_width=fill_parent ImageButton android:id=@+id/button1 android:src=@drawable/ icon / ImageButton android:id=@+id/button1 android:src=@drawable/ icon / ImageButton android:id=@+id/button1 android:src=@drawable/ icon / /TableRow TableRow android:gravity=center_horizontal android:layout_width=fill_parent TextView android:text=hi / TextView android:text=please send this / TextView android:text=exit / /TableRow /TableLayout *Question Restated* How can I host an ImageButton within a TableLayout (or at least make it look like a table layout) without stretching having the TableLayout ImageButtons to fit the width of their columns? Most importantly is still keeping the text below the ImageButton. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

(And the built in Activity probably HAS the CALL_PHONE permission, so
it's not your app that needs the permission if you are handing off,

[android-developers] Re: ImageButton resizes within TableLayout -- How do i fix?
TextView android:text=please send this android:maxWidth=10dip / If your text requirements are complex, you can use other views below the image. You can also set the number of lines of text etc. On Feb 2, 7:54 am, Pete pcnof...@gmail.com wrote: *Scenario* I'm attempting to host Image Buttons with a descriptor TextView below each button. To do this elegantly, I decided to use a TableLayout. The resulting image should look something like like: [img1] [img2] [img3] hi please send this exit As you can see above, each image is properly centered within its cell and some text is displayed below. *Issue* Unfortunately, if the descriptive text is longer than the ImageButton is wide, then the ImageButton associated with that text is stretched. See below: [img1] [ img2 ] [img3] hi please send this exit *Failed Attempts* Setting Height Width: I've already tried to fix this by setting layout_width layout_height for each element, but within a TableLayout it does not seem to work (these seem to be ignored for the stretched item). Also I thought I could nest each row within a LinearLayout (vertical orientation) but for some reason the layout file will not render if an ImageButton is nested within a TableLayout TableRow LinearLayout. *Example Code* You can use this example XML to reproduce the issue at hand.

[android-developers] Questions in Calling Operation
Hi all Android developers, We are developing an application to automatically dial call, answer call, and drop call. But I met some issues when I tried to answer and drop call: 1. I could not get all calls' status. In current published SDK, there are only three status could be available: IDLE, OFFHOOK, and RINGING. But I wish that I could get more status about each call, not the whole status of phone, such as which call is active, which call is held, which calls are in a conference. Do I have any method to acquire these status? Or is it contained in future google development roadmap? 2. I could not answer an inbound call. From the SDK, we can see that the intent ACTION_ANSWER is used to handle an incoming phone call. But when I tried to call it to answer the incoming call, the activity crashed. From the search result in the group, I found that there are some others developers have met this issue, but no answer is given. Could any comment be available from Google Android Development team, or from Dianne Hackborn? 3. I could not drop a call. It seems this issue is a known issue for the Android SDK. What I want to know is that when we could get a workaround version to resolve it? Any comment is appreciated.

[android-developers] How can host machine connect to emulator using socket
Hi, everyone: How can my host machine connect to emulator using socket? In my application, I need emulator to open a server socket, then host machine connects to emulator as a client. But when host creates the socket using 10.0.2.15:x (x is the port which emulator is listenning), it doesn't work. I think maybe the address10.0.2.15 goes wrong. Is it a local address behind the virtual router and the host can't find? If so, how to find a correct IP address of emulator? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] HELP! Lost all my stats on Android Market!
Dear all, I was uploading my .apk file on Android Market and keep getting this: You have another published application on Market with the same package name (com.x.x). (Where x.x. is my package name). Go to that other application, and click upgrade. I do not have another published application with that package name because it was some how lost by the UI and it refused to accept my APK file! Can someone advise what I should do? Ideally I would like my old stats back. My Android Market account is the same as this email address. At the moment my app is back on the Market but using a different package name (to avoid the error), which means all my stats have been reset and users who wish to upgrade will need to inconveniently uninstall the old.
