Address NewApi Android lint warnings in src/media.
Android lint complains when we use APIs added to Android after ICS
because these will causes crashes if used on ICS devices. In cases where
we only call the API on later versions of Android, we need to annotate
the method or class with @TargetApi to tell Android lint that each
particular use of the new API is safe. This adds a bunch of such
@TargetApi annotations.
