OnPause and OnStop() called immediately after starting activity

Question

I have an activity that needs to turn screen on(if offed) when it is started. So in onCreate, I have:

this.getWindow().setFlags(
            WindowManager.La

I've noticed there is activity attribute in the AndroidManifest.xml called android:showOnLockScreen="true|false"

for example:

   <activity android:name="AlarmAlertFullScreen"
                android:excludeFromRecents="true"
                android:theme="@style/AlarmAlertFullScreenTheme"
                android:showOnLockScreen="true"
                android:screenOrientation="nosensor"
                android:configChanges="orientation|screenSize|keyboardHidden|keyboard|navigation"/>

I searched the web for its documentation but no luck, but from its name it should work as the Window flag WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED do.

the only document I've found

Specify that an Activity should be shown over the lock screen and, in a multiuser environment, across all users' windows [boolean]

Edit

can you please try to call your flag code before calling super.onCreate(...)

public class BaseActivity extends Activity {

    @Override
    protected void onCreate(Bundle bundle) {
    this.getWindow().setFlags(
            WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON
                    | WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
                    | WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON,
            WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON
                    | WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
                    | WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
        //then call super
        super.onCreate(bundle);
.
.
.
  }
}
