BundleableByteArray

@UnstableApi
public final class BundleableByteArray

A wrapper for byte arrays that allows them to be transferred over Bundle instances using shared memory.

This class should be used for transferring byte arrays whose size is not trivially small, e.g. below 5000 bytes, to ensure it stays well below the binder transaction limits.
