Programmatically disabling screen rotations in the entire Android application

Question

How do I programmatically disable screen rotations for an entire Android application?

Answer 1

As in keep it in portrait or Landscape no matter which way device is tilted? You need to add this to your manifest inside the activity that you want to limit

 android:screenOrientation="portrait" //Or landscape for horizontal.

If you want it different between activities just make your manifest look like this.

        <activity android:name=".Activity1" 
        android:screenOrientation="landscape">       
        </activity>

        <activity android:name=".Activity2" 
        android:screenOrientation="portrait">
        </activity>

        <activity android:name=".Activity3" 
        android:screenOrientation="landscape">
        </activity>
