        Intent intent = new Intent(this, VideoCallActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
        getApplicationContext().startActivity(intent);

// These flags ensure that the activity can be launched when the screen is locked.
Window window = getWindow();
window.addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
        | WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON
        | WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

// to wake up screen
PowerManager pm = (PowerManager) getApplicationContext().getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wakeLock = pm.newWakeLock((PowerManager.SCREEN_BRIGHT_WAKE_LOCK | PowerManager.FULL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP), "TAG");
wakeLock.acquire();

// to release screen lock
KeyguardManager keyguardManager = (KeyguardManager) getApplicationContext().getSystemService(Context.KEYGUARD_SERVICE);
KeyguardManager.KeyguardLock keyguardLock = keyguardManager.newKeyguardLock("TAG");
keyguardLock.disableKeyguard();

// For Incoming Call
// 1. declare
private MediaPlayer incomingCallMediaPlayer;
// .2 in onCreate, if I'm the person that's calling, ring the phone 
incomingCallMediaPlayer = MediaPlayer.create(this, R.raw.incoming);
incomingCallMediaPlayer.setLooping(true);
incomingCallMediaPlayer.start();
// 3. when I pick up, stop the player
incomingCallMediaPlayer.stop();

// I play R.raw.incoming if I'm being called.
// I play R.raw.outgoing when I'm calling.
// I understand if I'm the one calling from the number of participants in the "room" (this is a video call terminology) and by passing in a variable through the intent

// For Outgoing Call
// 1. declare
private MediaPlayer callingMediaPlayer;
// 2. in onCreate, if I'm being called, ring the phone
callingMediaPlayer = MediaPlayer.create(this, R.raw.outgoing);
callingMediaPlayer.setLooping(true);
callingMediaPlayer.start();
// 3. when another "participant" (this is a video call terminology) joins the "room" I stop playing the sound
callingMediaPlayer.stop();

// to Vibrate, add the code with the media players and stop vibrate with media players
