Problem in starting activity from broadcast receivers

[Hardik Trivedi]

Hi all,


I am using broadcast receivers in my application. I have registered receivers in manifest and activity file. It calls perfectly. Broadcast receiver will be called whenever user clicks power button.
for that I have used

<action android:name="android.intent.action.ACTION_SCREEN_OFF"></action>

and

IntentFilter filters=new IntentFilter();
filters.addAction(Intent.ACTION_SCREEN_OFF);
registerReceiver(new BackButtonHandler(),filters);

In onreceive of broadcast listener I am starting an activity

@Override
	public void onReceive(Context context, Intent intent) 
	{
		 Log.v(TAG, "Power button is pressed.");
		 this.memoContext=context;

		 Intent newIntent=new Intent(context.getApplicationContext(),RecordMemo.class);
		 newIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
		 this.memoContext.startActivity(newIntent);
	}

Now this activity is called also. But I can not see the view of an activity. Activity runs in background.

What could be the reason behind this.

Please let me know if my question is not clear.

After you intercept the SCREEN_OFF broadcast and start your activity does the screen turn on?

I am not clear.

As I have said after I intercept SCREEN_OFF I can see that my activity is called in log cat but than after android locks the screen and Activity which I have started went in background.

Actually I need to do it using back button. So can I trace the back button press event using Broadcast Receivers.
You can still ask for more elaboration.
