How Do I Make The Phone Go To Sleep?

Question

I have an application and instead of keeping the screen on, once the app runs I want the screen to go dark. How do I do this? I know that to make the screen stay on I do this:

getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

But I cannot find out how to make the screen go dark.

No I mean like the screen is off where you have to tap the button once to be on the lock screen — Jerg, Sep 25 '18 at 04:17

check this http://rdcworld-android.blogspot.com/2012/03/lock-phone-screen-programmtically.html

OR Try this one

WindowManager wm = Context.getSystemService(Context.WINDOW_SERVICE);   

//Lock device  
DevicePolicyManager mDPM = (DevicePolicyManager)getSystemService(Context.DEVICE_POLICY_SERVICE);
mDPM .lockNow();

What do I use for context? – Jerg Sep 27 '18 at 01:42
No need for getApplicationContext, the above Context is enough – Jins Lukose Sep 27 '18 at 02:20
