Question

Hi I need to know whether we can set password to our lock phone programmatically,that is we set a password inside the code and when press a button the screen will lock.I need to use because I need to find a simple method without setting security password).Is there a way to make this possible?

Answer 1

PowerManager manager = (PowerManager) getSystemService(Context.POWER_SERVICE);

// Choice 1
manager.goToSleep(int amountOfTime);

// Choice 2
PowerManager.WakeLock wl = manager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "Your Tag");
wl.acquire();
wl.release();

and define permission in xml file

<uses-permission android:name="android.permission.WAKE_LOCK" />
