android:resizeable

Indicates whether the application is resizeable for different screen sizes. This attribute is true, by default. If set false, the system will run your application in screen compatibility mode on large screens.

This attribute is deprecated. It was introduced to help applications transition from Android 1.5 to 1.6, when support for multiple screens was first introduced. You should not use it.
