Dificuldade com Permissão Location Android

[Psycop]

Boa tarde,

Estou a tentar colocar a funcionar um projecto open-source encontrado na internet mas estou com alguns problemas ao tentar implementar as permissões para o Location agora exigidas pelo compileSdkVersion 23 e buildToolsVersion "23.0.1" que quero utilizar.

O código em que estou a usar pode ser encontrado aqui: https://github.com/vyshane/rex-weather

/**
 * Implement an Rx-style location service by wrapping the Android LocationManager and providing
 * the location result as an Observable.
 */
public class LocationService {
    private final LocationManager mLocationManager;


    public LocationService(LocationManager locationManager) {
        mLocationManager = locationManager;
    }

    public Observable<Location> getLocation() {
        return Observable.create(new Observable.OnSubscribe<Location>() {
            @Override
            public void call(final Subscriber<? super Location> subscriber) {

                final LocationListener locationListener = new LocationListener() {
                    public void onLocationChanged(final Location location) {
                        subscriber.onNext(location);
                        subscriber.onCompleted();

                        Looper.myLooper().quit();
                    }

                    public void onStatusChanged(String provider, int status, Bundle extras) {
                    }

                    public void onProviderEnabled(String provider) {
                    }

                    public void onProviderDisabled(String provider) {
                    }
                };

                final Criteria locationCriteria = new Criteria();
                locationCriteria.setAccuracy(Criteria.ACCURACY_COARSE);
                locationCriteria.setPowerRequirement(Criteria.POWER_LOW);
                final String locationProvider = mLocationManager
                        .getBestProvider(locationCriteria, true);

                Looper.prepare();

                if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
                    // TODO: Consider calling
                    //    ActivityCompat#requestPermissions
                    // here to request the missing permissions, and then overriding
                    //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
                    //                                          int[] grantResults)
                    // to handle the case where the user grants the permission. See the documentation
                    // for ActivityCompat#requestPermissions for more details.
                    return;
                }
                mLocationManager.requestSingleUpdate(locationProvider,
                        locationListener, Looper.myLooper());

                Looper.loop();
            }
        });
    }
}

 

O meu problema está no 'this' da permissão, o qual tem como erro o seguinte:

Citação

checkSelfPermission(android.content.Context,String)in ContextCompat cannot be applied

to(anonymous rx.Observable.OnSubscribe<android.location.Location>,String) 

 

Eu não sei como colocar isto a funcionar, se alguém me puder dar uma ajuda agradecia.
