keep the activity on screen even the lock button is pressed

I'm working on one project regarding calling.

Problem:

  • When I dial number and call, I can see a calling screen.Everything works fine until I press the lock screen button.

  • When I unlock my phone, I can see my calling screen for while but
    then it goes to the dialing screen (in which it requires a number to dial and then to call again).

  • Even though dialing screen is active the call is still continue(which is dial before lock) and it's working properly but then I can't
    access my calling screen to end the call. (disconnect call)

Here's my code : 

  private void stayAwakeOnLockScreen() {

        getWindow().addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
    }
Solution

  • use this code to add flags

    getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON|
        WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD|
        WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED|
        WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);

    and then in manifest

    <activity
    android:name=".yourActivity"
    android:showOnLockScreen="true" >
