I found the problem causing this issue. refer to http://stackoverflow.com/a/22524985/5020095
Because the example package is com.example and my android phone have a same name package.
I changed the com.example to com.examplei and the issue fixed.

Good catch!

This doesn't seem to be a problem with this package. Why did you reopen the issue?
