Question

I am creating an android application that needs to keep the device awake (will not lock) like this:

please help me to add the "Screen light lock" check-box in my settings activity. (in java, adt bundle eclipse)

Sorry for my poor English.

Answer 1

in your manifest :

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

in your activity :

PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
wakeLock = pm.wakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK |     
PowerManager.ON_AFTER_RELEASE, "My Tag");
wakeLock.acquire();

Answer 2

If you meant, you need to keep the device awake (will not lock), At the onCreate use this line of code:

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