Android 위치 업데이트가 반환되지 않습니다.

Question

Android 위치 정보를 얻으려고합니다.이 코드는 아직 반환되지 않았습니다. 스택 오버플로를 검색했습니다.

이 버그를 발견했습니다 : https://code.google.com/p/android/issues/detail?id=57707 하지만 지금까지 수정 사항이 없거나 찾을 수 없습니다. 이것은 코드입니다. 어떤 도움이 많이 주시면 감사하겠습니다

Criteria criteria = new Criteria(); 
    criteria.setCostAllowed(true); 
    criteria.setAccuracy(Criteria.ACCURACY_COARSE); 
    final LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE); 
    String provider = lm.getBestProvider(criteria, true); 
    Location l = lm.getLastKnownLocation(provider); 
    final String date = fmtForPresenter.print(dt); 
    if(l==null) { 
     lm.requestLocationUpdates(provider, 100, 200, 
       new android.location.LocationListener() { 
        @Override 
        public void onStatusChanged(String provider, int status, 
               Bundle extras) { 
        } 

        @Override 
        public void onProviderEnabled(String provider) { 
         Log.e("PROVIDER", "PRO: " + provider); 
        } 

        @Override 
        public void onProviderDisabled(String provider) { 
         Log.e("PROVIDER", "PRO: " + provider); 
        } 

        @Override 
        public void onLocationChanged(final Location location) { 

         lat = location.getLatitude(); 
         lng = location.getLongitude(); 
         presenter.getFoot(userProfile.getToken(),"public",lat,lng,date); 
         if ((ContextCompat.checkSelfPermission(getApplicationContext(), android.Manifest.permission.ACCESS_FINE_LOCATION) == 
           PackageManager.PERMISSION_GRANTED && 
           ContextCompat.checkSelfPermission(getApplicationContext(), android.Manifest.permission.ACCESS_COARSE_LOCATION) == 
             PackageManager.PERMISSION_GRANTED)) { 
          lm.removeUpdates(this); 
         } 
        } 
       }); 
    } 
    else { 
     lat = l.getLatitude(); 
     lng = l.getLongitude(); 
     presenter.getFoot(userProfile.getToken(),"public",lat,lng,date); 
    }

는 위치를 얻기 위해 타격 코드를보십시오 ... 그리고 또한 위치 서비스가 장치에서 활성화되어 있는지 확인

locationManager = (LocationManager) getActivity().getSystemService(Context.LOCATION_SERVICE); 
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 400, 1000, this); @Override 
public void onLocationChanged(Location location) { 
    LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude()); 
    CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(latLng, 8); 
    mMap.animateCamera(cameraUpdate); 
    locationManager.removeUpdates(this); 
} 

@Override 
public void onStatusChanged(String s, int i, Bundle bundle) { 

} 

@Override 
public void onProviderEnabled(String s) { 

} 

@Override 
public void onProviderDisabled(String s) { 

}
