I using a MockLocation to test the code, but notification is not coming.
from google-play-services.
Hello: I am in the process of doing a pull request for this but in order to test that the permission request and grant/denial are working correctly, I had to update the target version in each LocationLesson module build.gradle files and these files are in the master .gitignore for the repo. How should I handle the commit/push in this case? Melanie

You can find information on how to request permission for Android 6.0+ (API level 23+) here:

This is my MainActivity.java with the added permissions:
