Add android:screenOrientation="portrait" to the manifest under your main activity. <activity android:name=".yourActivity" android:screenOrientation="portrait"... /> Yes! It's an attribute of the activity tag: <activity android:name=".yourActivity" android:screenOrientation="portrait" ... /> Also, you may have to add the following to your activity element: android:configChanges="keyboardHidden" That way, the OS won't change the orientation when the user opens
