Hi, I have just created this small application which shows simple textview on receiving incoming call. This app works perfectly on emulator. Also it works very well when I launch main activity of application and I receive incoming call. But now if I restart phone and if I receive incoming call, the TextView UI won't show up. If I check debug log everything seems working fine i.e. my broadcast receiver receives event and invokes function to show UI. But actual UI never shows up. Now if I again launch application main activity and receive incoming call, UI shows up properly.
Below is the code snippet: --------------------------------------------------------------------------------------------------------------------------------------------------- public class IncomingCallReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent arg1) { TelephonyManager telephony = (TelephonyManager) context .getSystemService(Context.TELEPHONY_SERVICE); int callState = telephony.getCallState(); switch (callState) { case TelephonyManager.CALL_STATE_IDLE: { Log.d(MainActivity.TAG, "CALL_STATE_IDLE"); hideUI(context) ; } break; case TelephonyManager.CALL_STATE_OFFHOOK: { Log.d(MainActivity.TAG, "CALL_STATE_OFFHOOK"); hideUI(context) ; } break; case TelephonyManager.CALL_STATE_RINGING: { Log.d(MainActivity.TAG, "CALL_STATE_RINGING"); showUI(context) ; } break; } } private WindowManager mWindowManager; static View mainView ; private void showUI(Context context) { mWindowManager = (WindowManager) context .getSystemService(Context.WINDOW_SERVICE); WindowManager.LayoutParams lp = new WindowManager.LayoutParams( LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.TYPE_TOAST, WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE | WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE, PixelFormat.OPAQUE); TextView view = new TextView(context); view.setText("This is text view do you see it ?"); mainView = view; mWindowManager.addView(view, lp); Log.d(MainActivity.TAG, " showUI done"); } } ---------------------------------------------------------------------------------------------------------------------------------------------------------- Not sure what could be the cause of behavior . Any clues ? --Tushar -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
