Android | How to keep orientation unlocked even after changing orientation programmatically?

Question

I have a video player where user can change orientation manually also by rotating the device and by pressing a button click. When i am clicking the button, orientation changes to landscape but now the orientation gets locked and user cannot move back to portrait just by rotating the device I have tried this :-

activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

and this :-

activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE);

but none of it seems to work. So, how can i keep the orientation unlocked at all times plus user can switch orientation with a button click keeping the orientation unlocked ?

Answer 1

Try this,after changing your desire condition

activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED);

Answer 2

After I changing the orientation using a button, I changed the orientation to unspecified within a handler to assure that the orientation has been changed. Here is my code:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_USER_PORTRAIT);
    new Handler().postDelayed(new Runnable() {
        public void run() {
            // make screen orientation unspecified (sensor change it 
            //according to user action)
            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED);
        }
    }, 3000);
