The usual way to achieve that is to take advantage of the fact that Java won't load a class until it's first needed. Wrap up code that calls API functions that might not always be there (the getSupportedVideoSizes() call in your example) in a class which only gets instantiated if deviceLevel >= 11. On top of that, you'll need to build against a version >= 11 (in Eclipse, set your Project Build Target to >= 11) so that your new wrapper class doesn't give you compile errors.
