Throw exception when initialization failed.

Previously the initialization return code was ignored, it will lead us
crash later. We need a way to exit and maybe show error message if something
wrong during initialization.

Using exception might better than returning the result code since the
initialization code could be called from constructor and initialization
error is an exception at most of time.

In activity, the exception is caught, then call finish() to exit.

In tests, the exception is wrapped with Error and threw out.
