Lock Android phone application in portrait mode

Question

Can someone tell me how to lock my app in portrait mode? Is this a simple configuration in the manifest file?

Answer 1

Yes. Add android:screenOrientation="portrait" to the manifest under your main activity.

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

Answer 2

Yes! This is an attribute of an activity tag:

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

Answer 3

In addition, you may need to add the following to your activity element:

 android:configChanges="keyboardHidden" 

Thus, the OS will not change orientation when the user opens the sliding keyboard.
