Update Android Studio.
Catch IndexOutofBoundException. Crash report says match.find is called with start=35; length=34

I don't know how to reproduce, but ignore this is safe.
Change miniSDK from 14->16. removeOnGlobalLayoutListener is from SDK 16.
Work around for "local path doesn't exist".
Implement export.
Tablet mode couldn't delete. Just ignore activate state.
Implement import.
