Locking the screen to landscape for only one activity

I have looked around SO and found how to lock my entire application to Landscape by editing the Manifest file. However, this is not what I want.

I want every activity to be locked portrait, except for one, which will be locked to landscape.

Solution

In your manifest file, find your Activity declaration and use the following:

    <activity
        android:name=".ActivityName"
        android:label="@string/app_name"
        android:screenOrientation="landscape" >
    </activity>
