Android [Java] How to fix broken extension?

[Pamela Howard]

disclaimer: i'm not sure if this is the correct subforum, feel free to move me

I was using "Device Location" by Rani_sputnik for my Android game. This extension has since been removed and no fix has been released publicly by the developer. As my game relies heavily on this feature, and my knowledge of Java is basically nil, I'm in a bit of a pickle

I have uploaded the code in the .java file here for all of you to look through. I'm getting the following Lint errors:

Priority: 9 / 10
Category: Correctness
Severity: Error
Explanation: Missing Permissions.
This check scans through your code and libraries and looks at the APIs being used, and checks this against the set of permissions required to access those APIs. If the code using those APIs is called at runtime, then the program will crash.

Furthermore, for permissions that are revocable (with targetSdkVersion 23), client code must also be prepared to handle the calls throwing an exception if the user rejects the request for permission at runtime.
