16lz 2021-01-23

Solution 1: use PowerManager and WakeLock

In AndroidManifest.xml:

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

In your Activity:

    PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);    PowerManager.WakeLock mWakeLock = pm.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK, "My Tag");         // in onResume() call    mWakeLock.acquire();         ...    // in onPause() call    mWakeLock.release();

Solution 2: use the window flag FLAG_KEEP_SCREEN_ON

Put the following code in your Activity’s onCreate method:

    @Override    protected void onCreate(Bundle icicle) {        super.onCreate(icicle);        // Set keep screen on        getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);    }
