Check if screen is unlocked

How can I check if the screen is unlocked (E.i. Turned on and not on lockscreen)?

PS. I'm not looking for the unlock event, which I know can be retrieved with an AdminDeviceReceiver, but I'm looking for an executable code that will return a boolean telling me whether or not the screen is unlocked.

As per google Doc inKeyguardRestrictedInputMode is Deprecated. Instead of You can use below method for phone is wake up or not.

private boolean isPhoneIsLockedOrNot(Context context) {
        boolean isPhoneLock = false;
        if (context != null) {
            KeyguardManager myKM = (KeyguardManager) context.getSystemService(Context.KEYGUARD_SERVICE);
            if (myKM != null && myKM.isKeyguardLocked()) {
                isPhoneLock = true;
            }
        }
        return isPhoneLock;
    }

Check the Screen Off State in your onPause Method using Power Manager

@Override
protected void onPause()
{
    super.onPause();

    // If the screen is off then the device has been locked
    PowerManager powerManager = (PowerManager) getSystemService(POWER_SERVICE);
    boolean isScreenOn = powerManager.isScreenOn();

    if (!isScreenOn) {

        // The screen has been locked 
        // do stuff...
    }
}

Try with this:

   KeyguardManager myKM = (KeyguardManager) сontext.getSystemService(Context.KEYGUARD_SERVICE);
   if( myKM.inKeyguardRestrictedInputMode() ) {
        // it is locked
   } else {
        //it is not locked
   }
