[Android] Fix the issue of '--app-root' and '--app-local-path'

For make_apk.py, if the option '--app-root' is required, it's
necessary to include the option '--app-local-path' as well.
Besides, split the test cases in 'testEntry' into 2 categories:
one is for testing correct cases and another is for failures.
Merge pull request #797 from yongsheng/testentry
