orientation lock in android programmatically

Question

I have the following code.

Java

public void lockScreenOrientation() {
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_NOSENSOR);
}

public void unlockScreenOrientation() {
     setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR);
}

I am calling these functions from javascript. Control is entering these methods. However the orientation is not locked.

I have tried following to lock the orientation

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_NOSENSOR);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE);

None of these seem to work. Any pointers would be helpful.

Answer 1

Activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LOCKED);

Locks the screen (activity) in whatever the orientation it was.
