Disable Lock Screen

Question

I am looking for a way to replace the stock lock screen (with an app, not a rom). What is the best way to do it, for a start to disable the lock screen on as much devices as possible? Thanks!

KeyguardManager keyguardManager = (KeyguardManager)getSystemService(Activity.KEYGUARD_SERVICE);
KeyguardLock lock = keyguardManager.newKeyguardLock(KEYGUARD_SERVICE);
lock.disableKeyguard();

in androidmanifest:

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

The class KeyguardLock has been deprecated. Setting the window flags as shown by @hsgubert below seems the current way to turn off the key guard/lock screen. – pstoppani Feb 01 '13 at 00:48

You can just use this line in the activity:

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

Try this, it will keep awake the screen/ display , as long as the activity is on top.

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

Also this does not require any permission in manifest.

@CopsOnRoad. Solution seems to be different than that is provided by hsgubert. Is it something I am missing here ? – Swapnil Kale Mar 13 '18 at 21:11

Check out this link http://thinkandroid.wordpress.com/2010/01/24/handling-screen-off-and-screen-on-intents/

listen to the screen on intent and I guess just launch your lock screen.
