Answer 1

java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare() seems to be a pretty detailed error message; if it errors at that particular line (I'm assuming the handler is being created there) and judging from the stack trace, I would suggest calling Looper.prepare() before the error occurs.
