How to Fix Screen Orientation

How do I stop my Android app rotating?

There are a number of reasons that you may want to prevent your screen from rotating. When an Android device is rotated, by default the currently running activity is restarted. This will often require you to code to maintain the state that the activity was in prior to rotation. Alternatively you may simply want to display only in landscape, perhaps for a game.

To fix your screen orientation, simply set the screenOrientation attribute of the activity within your project manifest, as shown below, to either portrait or landscape:

<activity
    android:name=".myActivity"
    android:screenOrientation="portrait">

You can also do the same thing in code:

myActivity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

Please refer to the official documentation for more details.
