docker installation not working

[eddiebarry]

Tried to build the android app, but the instructions in the docker installation were raising errors

`ERROR: Analysis of target '//mediapipe/examples/android/src/java/com/google/mediapipe/apps/objectdetectiongpu:objectdetectiongpu' failed; build aborted: no such package '@local_config_git//': Traceback (most recent call last):

Please make the following changes in the Dockerfile. With those changes, I can successfully build MediaPipe Android APKs in a docker container. We will push out those changes in the coming release.
