Attempting to put Android device to sleep, but the PowerManager does not contain a "goToSleep(long) method

Question

I am attempting to put a device to sleep and I have found references all over about using the PowerManager class\'s goToSleep(long) method but I do not see it in the documen

Answer 1

PowerManager manager = (PowerManager) getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wl = manager
    .newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "YOUR_OWN_TAG");
wl.acquire();
wl.release();

Try this way and give some feedback.
