Indicates whether the application can resize itself to newer screen sizes. This is mostly used to distinguish between old applications that may not be compatible with newly introduced screen sizes and newer applications that should be; it will be set for you automatically based on whether you are targeting a newer platform that supports more screens.

Must be a boolean value, either "true" or "false".

This may also be a reference to a resource (in the form "@[package:]type:name") or theme attribute (in the form "?[package:][type:]name") containing a value of this type.
