For an unknown reason, when I tried to build my Google App Engine endpoints, I get these errors in all of the API java files generated by Android Studio:

**Error:(400, 5) error: method does not override or implement a method from a supertype
Error:(402, 29) error: cannot find symbol method setBatchPath(String)**

I did some initial troubleshooting and found out that there's a Builder class inside the java file and it extends **AbstractGoogleJsonClient.Builder**. I looked at the source for the Builder class and I cannot find the method.

Why all of the sudden am I getting these errors? Help!
