Moved navigation inside of Android Device

Summary:
It makes more sense for the navigation ability to be inside the Device's class instead of scattered throughout the rest of the app.

I have moved the Android navigation logic inside the AndroidDevice and added a function stub to BaseDevice. I also encoded the URI as an initial safeguard to injection attacks via adb, but will remove this altogether once I enable navigation through the socket connection.
