How does this even work

In the readme

@AfterPermissionGranted(RC_CAMERA_AND_LOCATION)
private void methodRequiresTwoPermission() {
    String[] perms = {Manifest.permission.CAMERA, Manifest.permission.ACCESS_FINE_LOCATION};
    if (EasyPermissions.hasPermissions(this, perms)) {
        // Already have permission, do the thing
        // ...
    } else {
        // Do not have permissions, request them now
        EasyPermissions.requestPermissions(this, getString(R.string.camera_and_location_rationale),
                RC_CAMERA_AND_LOCATION, perms);
    }
}

1. What is RC_CAMERA_AND_LOCATION?
2. Why are we checking if the permissions are not granted in an AfterPermissionGranted decorated function?

@phanirithvij that method works like this:

1. If you have CAMERA and ACCESS_FINE_LOCATION permission, do some action.
2. If you don't, request the permissions.
3. If the user grants the permission request, re-run the same method. Now you should hit the branch (1).

RC_CAMERA_AND_LOCATION is any constant number you want. Very similar to how you specify your own request code in startActivityForResult. It lets us know which method to come back to.
