[android-developers] App is crashing because of android.os.FileUriExposedException
The app is crashing when I'm trying to open a file. I found the log android.os.FileUriExposedException: file:///storage/emulated/0/test.txt exposed beyond app through Intent.getData() I know the solution of this problem. I fixed in the newer version of the app. For new version of app, I used FileProvider for apk installation, but old version of app use Uri.*fromFile*(dest). Now the problem is the auto update of the app. I need to update app automatically from the old version of the app. When I tried to update new app it donload the app, but when try to install app it is crashing. Is there any way to install app from the old version of app? NB: previous developer didn’t use play store for our app. Thanks in advance -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: Who decided the new SMS API in 4.4 was a good thing!??
I clearly understand your frustration. And I may not have the right to say something about this since I don't use the SMS API. On the other hand, let me try to take on the users hat: You certainly know that some users have to pay for each SMS, typically significantly more than to transfer a similar amount of data via an internet connection. I actually think using SMS for such a task is the wrong approach to start with. In my opinion, the best solution would be if the bank provides another way to access that information (something like a rest web service?). Of course, if there's no other way provided by the bank and you have no influence, you may have no other chance. However, in this special case, the blame seems to be on the bank and less so on Google (I certainly don't want to defend Google. There do numerous things I don't like , e.g. not fixing bug 3434)...

But now with the new 4.4 API, the app no longer can operate without cluttering up the Inbox and Sent box of the SMS application... Why on earth would a user need to save the sent messages for such an app?? And also, before I could stop the response from being written to the inbox, this is no longer possible.. And in the text from Google about this API change it says: this will create a better user experience How on earth is this going to be a better user experience for my users!!??? Now my users have to manually open the default SMS app and delete all the messages that should not have been written to the SMS provider...

[android-developers] Re: Some tablets marked as Incompatible in Play Store, but not in Developer Console
Funny, you seem to ask for help but don't want to try the suggestions insisting it's Googles problem and thinking they would solve it... Looking at your manifest, I think there may be problems regarding screen compatibility mode. See http://developer.android.com/guide/practices/screen-compat-mode.html and http://android-developers.blogspot.de/2011/07/new-mode-for-apps-on-large-screens.html. Now, why does the problem occur without changes to the manifest? Yes, there may have been changes made by Google. However, I would not wait until Google fixes the problem. That's not necessarily Googles strength. It may even be the case that Google does not think it does something wrong. Instead, I would add a supports-screens element and set android:targetSdkVersionhttp://developer.android.com/guide/topics/manifest/uses-sdk-element.html#target. The values you should use depend on your app. I also would use a current sdk version to build the app. Achim Am Mittwoch, 22.

Re: [android-developers] USB host
Yes, it may be. That indicates that the hardware (adapter etc.) is ok and
thus the device is recognized on the linux/os level but it's not made
visible on the level of the android USB-Host api (it's the same e.g. with
usb mice etc.). It may be that android tries to use it as some standard
rs232 hardware or as serial mouse or something.
That's probably also the reason why Sick USB 2 Serial Terminal does not
find your device: it's not visible on the api level.
Like Tux, I would recommend using another kind of device too. The IOIO is
great, but depending on your use case, it may be overkill. There have been
other projects with usb 2 serial adapters. You may find recommendations via
Google.

If you can see your device in the android tab, then you are right and
it's a software issue.
I'm not sure about the device_filter.xml. Do you have to specifiy the
values in hex or decimal? The docu uses e.g. class=255 and does not use a

Re: [android-developers] USB host
I would first check the hardware/cable etc. e.g. with the app USB Device
Info
https://play.google.com/store/apps/details?id=aws.apps.usbDeviceEnumerator
If you can see your device in the android tab, then you are right and it's
a software issue.
I'm not sure about the device_filter.xml. Do you have to specifiy the
values in hex or decimal? The docu uses e.g. class=255 and does not use a
hex-only digit. That looks to me like it could be decimal?

Re: [android-developers] Is the 'back' button still kosher?
I disagree with latimerius and his aversion for the android features. Yes, android significantly changed from version 2 to 3/4 and yes, this causes significant work for developers. However, there was a reason: to expand the android way to tablets. Avoiding the platform just guarantees that your apps will feel alien. Platforms change and if you want your app to feel native, you have to adopt. Such is life. Regarding your question: yes, I would use the back button (no matter if it's a hard button or an on-screen button displayed by android itself) to get back to the main screen from the sub-screens. If the back button is pressed while playing, many games pause and aks what to do (continue / Main menu) via a pop-up menu. While that menu is displayed, you may respond to pressing one of the offered menu options and alternatively to pressing back again. However, back button while a menu is displayed normally means just hide the menu. I.e. it should not go to the main screen but continue the game. Am Freitag, 2. November 2012 17:02:58 UTC+1 schrieb Keith Wiley: Thanks for coming back to my original question. So, perhaps we can all consider my situation from a higher level and discuss the possible design options we might choose from (and which options are most in the spirit of intended Android user experience). Although I have a few Android apps, the one I'm concerned with at the moment is a game and the back button is used to move between the various screens. So, when the game launches you get an on-screen menu of options (settings, scoreboard, play, credits). Tapping those takes you to a corresponding screen while tapping the back button takes you from those secondary screens back to the main menu (or from the main menu it exits the app). Likewise, while playing, the back button doesn't immediately exit play mode back to the main menu but rather first pauses the game. From the paused view, a second back button tap cancels play and returns to the main menu...while tapping the paused screen (anywhere) resumes play. That's pretty much it...and my question is whether I need to offer a nonback-button method for these various actions? Should each of the secondary screens have an on-screen return to main menu button? Should the main menu have an explicit quit option? Should in-game-play not rely on the back button to either pause the game or cancel and return to the main menu? These are the things I'm thinking about with as far as this discussion is concerned.

I brought this up a few weeks ago on this list and some of the advice on the topic was to avoid menus entirely and replace them with in-app soft-menus from now on...despite the action bar. I guess that advice was incorrect. There are developers who do not want to use the action bar, such as game developers who find that an always-present action bar is a distraction or clashes with their game-focused UI. A subset of those developers are clinging desperately to the old options menu behavior (e.g., setting android:targetSdkVersion to be under 11) -- the right answer for these game developers is to add in-app soft menus that blend in with the game UI. The right answer would have been for Google to leave the button alone - but we've talked about that already, the button was universally useful, and there's not always a UI to blend in anyway. Back on topic, my lesson for my remaining days on Android from the Menu button fiasco and other breakages caused by previously guaranteed stuff being pulled at whim from under people using them would be - interact as little as possible with the platform. Don't rely on stuff on being there cause it likely won't, don't rely on APIs cause they will be deprecated or changed. As far as the Back button specifically, one would think that should be safe to rely on. Based on experience though, my advice would be, think hard about what you need it for and what your alternatives are. If you find any half-decent one, consider using it. You might be glad you did once next version of the platform is out. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Nexus 7 USB Host - Not able to enumerate device
HI,
first: USB-Host including the USB-Host api works for me on the Nexus 7 - no
root required.
You could try an app like USB Device Info to validate your hardware setup
(usb adapter etc.).
I have setup intents and filters, but I also assume they are not necessary
if you scan for devices yourself.
As I understand it, you just tried a mouse and a phone? I just made a test
with a mouse and though USB Device Info saw it on the linux tab, it did
not see it on the android tab. My app also did not see the mouse. I
assume since android handles the mouse itself, it does not make it visible
to the app.
I.e. try another usb device. If you can see it on the Android tab in USB
Device Info, you probably should see it in your app.

Hi All,
I recently bought a Nexus 7 for USB development. I would like to use the
USB Host functionality provided by the new Android OS. I was following the
USB Host Tutorial at the link:
http://developer.android.com/guide/topics/connectivity/usb/host.html.
My program is very simple, and here are the relevant parts of the code:
*private UsbManager manager;
*
* *
*public void onCreate(Bundle savedInstanceState) {*
*super.onCreate(savedInstanceState);*
*setContentView(R.layout.activity_main);*
**
*Log.i(TAG, in onCreate());*
*manager = (UsbManager) getSystemService(Context.USB_SERVICE);*
*if(manager==null) {*
*Log.i(TAG, USB Manager is NULL);*
*}*
*else {*
*Log.i(TAG, USB Manager = + manager);*
*}*
*}*
**
*public void enumerateUSBDevices() {*
*HashMapString, UsbDevice deviceList = manager.getDeviceList();*
*CollectionUsbDevice deviceCollection = deviceList.values();*
*IteratorUsbDevice deviceIterator = deviceCollection.iterator();*
*Log.i(TAG, Number of connected USB Devices = +
deviceCollection.size());*
*while(deviceIterator.hasNext()){*
*UsbDevice device = deviceIterator.next();*
*Log.i(TAG, device.getDeviceName());*
*}*
*}*
When the enumerateUSBDevices function is called, it reports that the
number of connected USB Devices = 0. I am using a USB OTG cable, and I
know that the Nexus 7 is powering the connected USB Device because I
plugged in a USB Mouse, and it works properly. I also plugged in another
Android phone, and the Nexus 7 was confirmed to be powering the device.
However, in both of these instances, the Android program says that there
are no USB devices connected. I am unsure what is going wrong in my code.
In my Android manifest, I have the following line:
*uses-feature android:name=android.hardware.usb.host /*
My manifest does not have any intent filters associated with any USB
devices. My understanding based on reading the tutorials is that the
intent filters need to be in the Manifest only if you want the APP to be
notified when the USB device is connected after the App is running?
Can anybody shed light into what I may be doing wrong? Do I need to root
my device?
Thanks,
Kiran

I was intending to use the keys for authentication, and the phone is playing a server role here, meaning that only the computer would need a private key. Once it has been generated, the public key could indeed be sent over wifi safely. You do still have the two problems left, selecting a phone and getting the key unmodified, but those are solvable indeed. However, I have been thinking about this and I feel it might be necessary to extend the service beyond the original idea of only using it over wifi and allow use over the internet as well. The idea would still be the same: having a phone app and a computer application communicate (possibly through a server). Here it might be necessary to encrypt all data sent and thus we may need to have a key pair on both ends. However, that's not really what changes the situation. What changes the situation is that the two problems above get so much bigger. The data will now be sent over a much less secure connection and there are many more wrong phones you might connect to. I am not saying that isn't solvable, but this makes me want to at least offer USB setup as an option. It is possible to just connect over usb like that?

The problem is to be sure you got the right ones (i.e. that they have not been faked by e.g. a man in the middle attack). To ensure this, you might e.g. calculate a cryptographic hash of the public keys (to shorten the data that has to be compared) and display them on both sides. The user may then compare the hashes.

[android-developers] Re: USB to PC connection
Getting cryptography right is non-trivial. So take this with caution. As I understand it, you want to generate a key pair on each side and exchange the public keys. That can be done easily via wifi too since you only exchange _public_ keys. The problem is to be sure you got the right ones (i.e. that they have not been faked by e.g. a man in the middle attack). To ensure this, you might e.g. calculate a cryptographic hash of the public keys (to shorten the data that has to be compared) and display them on both sides. The user may then compare the hashes.

In order to do this in a user-friendly way, I want to do so automatically over usb. However, in exploring how much of what I want is actually possible on android, I have been unable to find out how to have an app communicate over usb to a program on the computer. Technically, it would be similar to using the computer as a USB accessory, but I doubt it would actually be similar enough to make this work. I have also read that it might be possible using ADB port forwarding, but this doesn't really look like it would make it more user-friendly for end users. Finally, I suppose I could solve the problems by only using the file system and mounting it, storing the public key in a file on the s-card, but it's not really the ease of use that I am looking for. Is there a way of communicating between an application running on a pc and an app running on an android device that I have missed?

Re: [android-developers] Java 1.7
Didn't the lawsuit go well for Google? As far as I know, the judgment was that language syntax and api cannot be patented. Of course, implementing the new library would be quite some effort. But supporting the new java syntax should not be such an effort. As far as I know, on bytecode level only invokedynamic was added and that code is not used by the java compiler (only by dynamic languages like jruby). So, a quick way to enable the new syntax features seems to be to 1) remove the errors warnings 2) add an error/warning if invokeDynamic is used Alternatively, it might be possible to add an additional build step (or eclipse builder) to just patch the version number of the class files to pretend they are java 1.6 class files. Am Mittwoch, 13. Juni 2012 16:36:03 UTC+2 schrieb Daniel Drozdzewski: It probably won't be supported soon for multitude of reasons. Simply set compiler compliance to 1.6 in Eclipse and live without funky Java 7 features. I know, it is not, what you asked for, but features of Java 7 are a bit more than the nice way of representing numerals. Have a look here: http://www.oracle.com/technetwork/java/javase/jdk7-relnotes-418459.html ... that's quite a lot to port to Dalvik (even when only looking at HotSpot and language changes). Bear in mind that many new things in Java7 are possible specifically because the platforms that Java7 addresses have different (much more relaxed) constraints compared even to 4 core 1GB RAM mobile device. For example InvokeDynamic allows JVM to run trully dynamic languages, which are high productivity and all that, but cost in terms of processing and memory. Technicalities aside, remember that Google and Oracle only finished one big lawsuit. I don't think big G would like to have another one on their hands just yet.

[android-developers] Re: Is JDK1.7 supported now?
My first thought was: there are probably new bytecodes in java 7 class files. In that case the transformation to dex files has to be changed and it's not clear if that's possible in a backward compatible way, i.e. without replacing the dalvik implementation on all devices, which is obviously not feasible. A quick search lead me to http://www.yworks.com/de/products_yguard_about.html (sorry, German), where they say, only the version number in class files changed and a new instruction (invokedynamic) has been added. However they also say, invokedynamic is not used by current java implementations, only by dynamic languages like JRuby. In that case, it seems possible to work around this issue: just write a small tool to change the version number of the class files to the previous number and add that tool as an additional build step.

Using spannables directly is certainly the better way to do it since the
supported html tags apparently are not clearly specified as Mark already
mentioned.
However, out of curiosity, I looked at the source of Html.java. So, just
for the sake of completeness: I found that font apparently only supports
the attributes color and face, but not size. I also found that it
supports big and small, i.e. using an html string like
big199/big smallkm/h/small seems to work, although you cannot
specify the sizes exactly...

Once you have the smaller text, you can use TextUtils.concat() to
build
up you final text. Just make sure you nowhere cast/toString() the
CharSequence to a String because you will lose the formatting info.

[android-developers] Timer in Android
Hello every one, I have a simple question about timer in Android, How can I know if the timer is stopped or not? I have an if statement which see if some condition is satisfied, then it will stop the timer by : if(timerTask != null) timerTask.cancel(); I want to check after calling the timer if the timer is stopped or not?

[android-developers] Re: Audio / Performance Issues on ICS / Android 4
I do something very similar in my apps (Grand Piano and Opus #1) without
problems on ICS. Sound generation is quite expensive in my case, so I have
problems on slow devices (1Mhz / single core / old android version) but
not on the galaxy nexus.
One thing I noticed however is that it seems like you use the same size
(minSize) for the AudioTrack buffer and the audio creation buffer used as
argument to processNativeAudio. Although more jni calls imply more
overhead, it might be better to use a smaller buffer size for the jni
calls, based on AudioTrack.getNativeFrameCount() or better yet a divisor of
it to ensure the audio creation thread does not need to wait that long on
the blocking call to AudioTrack.write().

Hello
I have a music (sequencer/synth) app in Android Market. One of its
strengths is that it uses very little resources and plays smoothly
even on the oldest and cheapest devices and only requires Android
version 1.6.
However, since the arrival of ICS, I get more and more complaints
about stuttering playback and a sluggish interface, mainly on Galaxy
Nexus. The app hasn't changed and still works fine on earlier versions
of Android.
I wonder what may have changed.
My app does the audio processing in native code and I suspect the way
data are passed between java and native might be the problem (I still
use AudioTrack to maintain 1.6 compatibility and because it always
worked fine):
public class PlayThread extends Thread
{
public void run()
{
ByteBuffer byteBuffer =
ByteBuffer.allocateDirect(minSize);
byte[] byteArray = new byte[minSize];
android.os.Process.setThreadPriority(android.os.Process.THREAD_PRIORITY_URGENT_AUDIO);
int minSize =AudioTrack.getMinBufferSize( 44100,
AudioFormat.CHANNEL_CONFIGURATION_STEREO,
AudioFormat.ENCODING_PCM_16BIT );
myTrack = new AudioTrack( AudioManager.STREAM_MUSIC,
44100, AudioFormat.CHANNEL_CONFIGURATION_STEREO,
AudioFormat.ENCODING_PCM_16BIT,
minSize, AudioTrack.MODE_STREAM);
myTrack.play();
while(1)
{
byteBuffer.position(0);
processNativeAudio(byteBuffer, minSize);
byteBuffer.position(0);
byteBuffer.get(byteArray, 0, minSize);
myTrack.write( puff, 0, minSize );
}
}
}
In the main activity, a new PlayThread is created on startup. The
native function looks like this:
void Java_com_myapp_ processNativeAudio( JNIEnv * env, jobject this,
jobject buffer , jint buflng)
{
jbyte *jbuffer = (*env)-GetDirectBufferAddress(env, buffer);
short *shortBuffer= (short*)(jbuffer);
// processing audio here and writing to shortBuffer
}
Anyone has similar problems or even knows a workaround?
Thank you.

[android-developers] Re: help in using android USB host mode
64 is the _max_ packet size. A single transfer may be shorter; it does not matter if the rest of the buffer is filled with zeros or some garbage since the data transfered is contained in just the first x bytes of the buffer where x is the return value from bulkTransfer. For continuous transfer, just call bulkTransfer multiple times. I don't know why you want to set a baud rate. You don't do this with usb transfers. Am Dienstag, 3.

[android-developers] Re: Arduino vs Io-Io
The ioio is a controller board with USB host and a firmware designed to communication with android devices (the android devices work as usb devices in this case). I.e. the ioio is kind of a replacement for android accessory boards that works with android = 1.6 (?) while android accessories need android = 3.1(?). Arduino boards typically have a usb device connector (this depends on the concrete arduino variant). As such, it can only communicate with USB host devices, i.e. not with all android devices. I'm also not aware of android software to communicate with arduino via USB. So for an arduino solution, you need either an USB host shield (in that case, you ?fromgroups#%21forum/ioio-userswould have to write something like the firmware oand the android lib of the ioio yourself) or bluetooth (see e.g. http://www.amarino-toolkit.net). The latency via bluetooth will be significantly higher than via usb, which may be problem depending on your application. Normally, I would recommend to use the ioio. However, I don't know if your project has requirements that would change this recommendation. You may ask further questions on the ioio user list https://groups.google.com/forum/?fromgroups#!forum/ioio-users?fromgroups#%21forum/ioio-users. It seems more appropriate than this list. Ytai, the developer behind the ioio, is very active on that list and provides great support. The ioio docu lives at https://github.com/ytai/ioio/wiki Am Samstag, 24.

[android-developers] Re: control micro-controller or any Hardware
There are basically three ways: 1) If you can constrict it to Android devices with USB host capability and Android 3.1 (basically good android tablets), you can use the USB APIs with the android device as Master (see http://developer.android.com/sdk/android-3.1.html, section USB APIs). 2) If you don't have USB host capability in the android devices, you can use the USB APIs with a USB accessory (see the same link as above). However, this still requires at least Android 3.1 and USB accessory basically means your USB hardware has to be designed programmed for this. 3) If you want to implement your solution for all (well, actually most) android devices, even prior to Android 3.1, you need special USB Host hardware. A simple way to go is the IOIO board. Basically, it's a microprocessor board based on a PIC microprocessor with USB host support and a (freely available) firmware and an Android library that can communicate with each other. This board can be connected to the normal USB connector you use to connect your android device with a PC.

[android-developers] Re: multitouch support again...
It works because returning true signals that the event has been consumed. That's the signal for the parent ViewGroup to set this view as a target. As a result, the pointer multitouch events are delivered to this target view. I think, the corresponding code is in ViewGroup.dispatchTouchEvent. You might want to take a look...

At first glance, I don't see a fundamental problem with your code

multitouch-capable. There are many free apps in the market to do this,
for example yamtt. If the device supports mutitouch, it may help to
debug into the onTouchEvent method or to log the event right at the
start of the onTouchEvent method, just to see what's reported...
Btw. capacitive touch screen indicates the technology used to
recognize touches (a different worse technology to do this are e.g.
resistive screens); multi-touch means the screen an recognize multiple
touches at the same time. So, that's not the same.

[android-developers] Re: Multi-touch with multiple buttons
getRawX/Y return the absolute coordinates off the current event on the
screen (i.e. they are not relative to the view that received the
coordinates). I don't know about getLocalVisibleRect(). It's not
documented in the api docs. It may return coordinates relative to the
parent view? In that case, it would help to use getX/Y.
It's also interessting to take a look into the source code of
ViewGroup.dispatchTouchEvent(). Basically, what happens there is:
int scrolledX = (int)(event.getX() + view.getScrollX)
int scrolledY = (int)(event.getY() + view.getScrollY)
Rect frame = ...
for each child
child.getHitRect(frame)
if (frame.contains(scrolledX, scrolledY)

There are some basic principles in android regarding multi-touch
that you should be aware of. Especially, wrt. your code these two come
to my mind:
1) If the first finger touches view A, all other touches will be
directed to view A as long as the first finger is still there, even if
the subsequent touches touch another view. I think, the reason to
implement it this way, was to ease implementation of gestures like
pinchzoom.
2) The action codes you will typically see during a multitouch
gesture are:
- ACTION_DOWN: this signals that the first finger touches the
display
- ACTION_POINTER_DOWN: the second, third, ... finger touches the
display
- ACTION_POINTER_UP: a finger was lifted, but there are still
fingers on the display
- ACTION_UP: the last finger was lifted
Of course, you may also see ACTION_MOVE events in between and after
a POINTER_UP, another POINTER_DOWN event may occur, if another finger
touches the display before all fingers are lifted, etc.
Regarding your code:
1) means that you have to capture the events at a view that is an
ancestor to all the buttons that should be part of the multi-touch.
I.e. put both buttons into a common parent and listen for the touch
events at the parent. You can then analyze the event to determine the
coordinates of the new touch point and use the coordinates to
determine the touched button. Be aware though, that some devices have
terrible hardware limitations (i.e. problems).
Seehttp://androidandme.com/2010/03/news/is-multitouch-broken-on-the-nexu...
for an example. I.e. the code has to take some strange behaviour into
account.
Regarding analyzing the event, don't confuse pointer id's with pointer
indizes. That's a problem that can be seen in various code examples
online.
2) means, you have to listen for ACTION_POINTER_DOWN and
ACTION_POINTER_UP (as well as ACTION_CANCEL) too.

I think there is another way to approach this which cuts out the need for the libraries, but you'll need to get the AOSP source. Once you've checked out the source from frameworks_base you can re-use an implementation available internally in Android from; frameworks/base/core/java/com/android/internal/http/multipart The instructions on how to use it are in the header comments of MultipartEntity.java Given the problems with kernel.org you can pick up the source code from the **unofficial** github mirror at https://github.com/android/platform_frameworks_base as a quick workaround to the kernel.org issues.

[android-developers] Re: How to prematurely stop a long-running SQLite query?
This all sounds to me like full-text search. So I would check if the full-text search support of sqlite (see http://www.sqlite.org/fts3.html) is available on android. A quick google search finds pages like http://bakhtiyor.com/2009/08/sqlite-full-text-search/;.

From Andy Rubins recent post at http://android-developers.blogspot.com/2011/04/i-think-im-having-gene-amdahl-moment.html ; Finally, we continue to be an open source platform and will continue releasing source code when it is ready. As I write this the Android team is still hard at work to bring all the new Honeycomb features to phones. As soon as this work is completed, we’ll publish the code.

[android-developers] Re: Android MediaPlayer sometimes stops playing a sound file early
hahaha. how silly. okay.. this is so stupid. here is the solution the problem that I have been facing this problem is occurring because I did not pay much attention while trimming my sound clip. i had recorded my voice in .ogg format and i am trying to use these voice clips as sounds for my button click actions. apparently, what i found is that, the android.media.MediaPlayerhttp://developer.android.com/reference/android/media/MediaPlayer.html *cannot* play a sound file upto its absolute completion - it ceases playback about 300 milliseconds before the actual end of the sound file data. Hence, in order to avoid this pre-matured stop of our recorded or edited sound-clips that we were facing (*i believe john.p was having a similar issue*), we must ensure that there is at least 300 milliseconds of silence after the last sound wave oscillation in the file. i have used the open source sound editing tool called *Audacity* to record my voice, normalize the voice, remove background noise, trim the sound clip, and additional 300 millisecond silence - it's an easy software and can be found here http://audacity.sourceforge.net/ -- You received this message because you are subscribed to the Google Groups Android Developers group.
