    There is already an API for this, Context.startInstrumentation:

    This is how the shell command is implemented. You can’t do anything more by launching a shell command than you can do in your own process. Also, no shell commands are part of the SDK, so anything you do with it is likely to break at some point on different devices or versions of the platform.
