What kind of files can be executed on Android?

Question

Android

The logic is this: the client Android mobile device receives some file, executes it, and returns the result to the server. The question is, what kind of files is easier / more correct / more logical / more convenient to send?

Or something scripted? Or what in general?
Thank you.
