[android-developers] RegisterBroadcastReceiver in Manifest.xml
Hi,
I am trying to register a callback when a get a call on my phone.
Here is what I am doing:
public class BroadcastActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
public class Receiver1 extends BroadcastReceiver
{
public void onReceive(Context context,Intent intent)
{
System.out.println(this + :GOT-THE-INTENT);
//-emulator-doesn't-support-vibration-
Vibrator v =
(Vibrator)context.getSystemService(Context.VIBRATOR_SERVICE);
v.vibrate(500);
}
}
}
This is my Manifest file:
application android:icon=@drawable/icon android:label=@string/
app_name
activity android:name=.BroadcastActivity
android:label=@string/app_name

Thanks for the reply. The 2 changes you mentioned made it work.

[android-developers] Re: RegisterBroadcastReceiver in Manifest.xml
Hi,
I had tried initially by dynamically using registering the receivers
using the registerReceiver(). I get the callback when I the
application is in the foreground. The problem I faced was that, when I
exit the application, I never got a callback on the receiver when I
try to trigger it from my service class.
From my service, I call:
Intent intent=new Intent(Consts.INTENT_UPDATE);
this.sendBroadcast(intent);
My receiver in my Activity class looks like this:
private BroadcastReceiver updateReceiver=new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
if(Consts.INTENT_UPDATE.equals(intent.getAction()))
{
update();
}
}
};
I do not unregister my receivers at onDestroy() and register during
onCreate().
Is there something I am missing.
Thanks,
Priyank

Not the way you're going about the problem.
The reason I can not put the Receiver1 class in a different java file
is that there are many UI changes I do when I receive the broadcast.
You will not be doing any changes to the UI when you receive the
broadcast. If you wanted to do that, you would not be using a
manifest-registered receiver. Use registerReceiver() in the activity
to register a BroadcastReceiver dynamically; that receiver can then
work with the activity to update the UI.
For example, here is an application that uses ACTION_BATTERY_CHANGED this way:

Thanks for the reply.. I understand that blocking could be a security issue. But enabling/ disabling should not be a problem. For example, if the app disables the 'installing non-market apps feature from my app, the user can go to settings and enable it back. Something like this would do.. Coz I know that this is possible for bluetooth n wifi.. The application could be the device admin if needs to..

However, you can remove a permission from any given app and block it from that app. But I think the answer to your question is no, you can't block access to other apps from your app, this would be a big security hole indeed if you could.

[android-developers] Using Fragmentation to navigate from one activity to another
Hi,
I wanted to use fragmentation in my application. Here is the
scenario.
There are 2 vertical fragments. The 1st fragment have buttons and
second fragment have screens that need to be displayed according to
the button pressed in the 1st fragment.
I have implemented this using the help of the android sample
examples .
But now, in the 2nd fragment as well there are buttons which on
clicking, we need to navigate in this fragment from one activity(xml)
to another(xml) within the 2nd fragment. That is the 1st fragment is
always visible to the user. I have multiple xmls which need to be
navigated from one screen to another on click of buttons. But these
screens needs to be there only in the 2nd fragment as the 1st fragment
should always show same buttons from the beginning.
This is my code of my 2nd fragment class. Here the entire screen is
occupied by the activity when i click on the button.
public static class DetailsFragment extends Fragment {
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
View v = (View) inflater.inflate(R.layout.testscreen, null);
Button b = (Button)v.findViewById(R.id.button1);
b.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v) {
displayNextScreen();
}
});
return v;
}
private void displayNextScreen()
{
Intent intent = new
Intent(getActivity(),NextActivity.class);
startActivity(intent);
}
}
Please help..
Thanks,
Priyank

emailLink.setMovementMethod(LinkMovementMethod.getInstance());

I think I am missing something in the manifest file. I am not sure what I
need to fill there. Whar do I enter in the data field in the intent filter?
Here is my intent filter I have defined in the corresponding activity:

Re: [android-developers] opening Android Email application from another application
Hi, Thanks for your reply. What you said worked. Instead of querying the email provider, I directly called the intent: emailIntent.setClassName(com.android.email, com.android.email.activity.Welcome); startActivity(emailIntent); But my doubt is that, I dont know whether the user has configured his email or not. i.e whether to call the Welcome activity or MessageCompose activity of the email application.

[android-developers] Recording Audio in Emulator
Hi, I am facing some problem when I try to run record an audio. In my startRecord() method, this is what I do: recorder = new MediaRecorder(); recorder.setAudioSource(MediaRecorder.AudioSource.MIC); recorder.setOutputFormat(outputfileformat); recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB); recorder.setOutputFile(path); The logs throw a audio_input error in this line: recorder.setAudioSource(MediaRecorder.AudioSource.MIC); The error is: 09-09 19:04:02.696: ERROR/audio_input(34): unsupported parameter: x- pvmf/media-input-node/cap-config-interface;valtype=key_specific_value 09-09 19:04:02.696: ERROR/audio_input(34): VerifyAndSetParameter failed I am using a microphone connected to my pc to record the audio. I am working on eclipse in windows xp. I was wondering whether this is because my PC microphone is not configured with the emulator ? I have seen a similar thread regarding this issue. I have configured the SD card and have set the path to the sdcard location. What is the command i need to give to configure my microphone to the emulator? emulator.exe -audio winaudio @androidvmdoesnt seem to work. Someone please help.

Re: [android-developers] Re: Starting an Activity from a callback class
I was able to fix the problem.
The issue was that i did not have the context instance in my callback class.
I created a constructor where I got the context from the service class.
Using that I was able to call the application activity class.
Also I had to use
myIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); for starting the task..
This was my constructor in the callback class
private VServiceCallBack(Context iContext)
{
context = iContext;
}
And according to the arguments received,
{
Intent appView = new Intent(context, AppView.class);
appView .addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(appView );
}
Sorry for the confusion, and thanks for the help..

But this is not working. Can anyone tell where i am going wrong and

Re: [android-developers] Extending multiple classes
Hi,
I am facing some when running the code. I am using the
getApplicationContext() to save the instance.
Kindly have a look at my code and let me know where I am going wrong.
VVMService is the class whose instance is created and got from the
onServiceConnected() callback
public class VVMServiceBind extends Activity
{
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
bindService(new Intent(VVMServiceBind.this, VVMService.class),
mConnection, Context.BIND_AUTO_CREATE);
VVMService appState = ((VVMService)getApplicationContext());
}
public void onServiceConnected(ComponentName className, IBinder
service)
{
Log.i(TAG, In onServiceConnected);
mService = ((VVMService.VVMBinder)service).getService();
appState = mService;
}
}
VVMClientApplication is the class where I need to access the VVMService
class instance.
public void serviceConnectionSuccess()
{
private VVMService mService;
mService = (VVMService)getApplicationContext();
}
dont I have to extend Application in any class ?
Thanks,
Priyank

Just invoke Activity.getApplication() within your Activity.onCreate method,
casting the Application to your specific class type. Then your can set
whatever you need on your application instance and it will be accessible

[android-developers] Multiple Back Button clicks needed to exit application
Hi, In my current application design, I have an activity class application.java (which starts on launching the application), and it does not have a layout(UI screen). I call another class called servicebind.java from the onCreate method of my 1st class. here I bind to the local server (bindServer()). i call back the application class through an intent. Once I am back to my application class, I call my activity class called welcome.java which has a layout/UI. When I run this application, I am able to see the welcome screen. But the problem is, when I click on the back button, I get a black screen with just the title on top. I have to hit back button 3 times to exit the application. The reason I see from the logs is that, the 1st 2 activity classes (application.java and services.java) does not get destroyed unless I hit the back button. So the 1st time I hit back button, the welcome activity gets destroyed. the next back button destroys the servicebind class and final back destroys the application class. Is the reason because these classes dont have a UI to display in the onCreate method. I do not want to change my design where I bind the service in the servicebind class and call the welcome activity in the application class. can anyone please help me find a way to avoid pressing the back button multiple times to exit. Please let me know if you dont understand my question. Thanks, Priyank -- You received this message because you are subscribed to the Google Groups Android Developers group.

Hi, Thanks a lot for your reply. I installed ArgoUML and am trying to figure how to use it. My project doesnt have a XMI file to import from. It consists of 2 modules. Application and Services. Each of them has 3-4 packages having about 15 .java files and a few resource files. I tried to do Import Sources in ArgoUML and selected the entire project. But I was not able to understand how to go ahead. Which perspective is the best to use in this scenario. Could you please tell me what I am doing is the right way. Or am I missing something .

If you are taking that code from one of my samples, the corresponding manifest from those samples is set up properly: http://github.com/commonsguy/cw-advandroid/tree/master/AdvServices/Re...

Intent i = new Intent(); i.setClassName(com.mt.TestRemoteService, com.mt.TestRemoteService.MyService); bindService(i, svcConn, Context.BIND_AUTO_CREATE); This is extremely fragile. If the other application refactors its code, your code will break. Why bind with Interface name is not working for me? ( Note: I have added an intent-filter on the service with a Interface action ) Whatever you think you did, it is not working. Rather than use my IScript.class.getName() trick, it is probably simpler for you to just use the literal string.
