Show dialog with touch events over lockscreen in Android 2.3

Question

I want to build a dialog which is visible on the lockscreen and can receive touch events. I built a window with WindowManager but only the TYPE_SYSTEM_OVE

Answer 1

Finally I achieved the same. Don't go for activity, because android will not show lock screen behind your activity for security reason, so for service.

Below is my code in onStartCommand of my service

WindowManager mWindowManager = (WindowManager) getSystemService(WINDOW_SERVICE);

View mView = mInflater.inflate(R.layout.score, null);

WindowManager.LayoutParams mLayoutParams = new WindowManager.LayoutParams(
    ViewGroup.LayoutParams.WRAP_CONTENT,
    ViewGroup.LayoutParams.WRAP_CONTENT, 0, 0,
    WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
    WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
            | WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD
            | WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON
    /* | WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON */,
    PixelFormat.RGBA_8888);

mWindowManager.addView(mView, mLayoutParams);
