Overview

AIMSICD crashed before when the MapFragment was opened, then another fragment (eg. DatabaseViewer) was opened afterwards and then the app was closed by the user by double tapping the back button. The MapFragment then threw a IllegalStateException.

I added check isAdded() to three points in the code to return null if fragment is not attached to prevent a crash when exiting the app.
