GPS 업데이트가 호출되지 않습니다.

GPS로부터 업데이트를 받고 싶지만 그럴 수 없습니다. onLocationChanged 메서드가 호출하지 않습니다. 이 응용 프로그램에서는 Google Maps API도 사용합니다. 나는 모른다. 어쩌면 내 문제의 원인 일 수도있다.GPS 업데이트가 호출되지 않습니다.

LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE); 

final LocationListener locationListener = new LocationListener() { 
      public void onLocationChanged(Location location) 
      { 
         txtLat.setText("Latitude: " + String.valueOf((int)(location.getLatitude())) + "," 
           + String.valueOf(((location.getLatitude() * 100) % 100)) + " degrees"); 

        txtLong.setText("Longtitude: " + String.valueOf((int)(location.getLongitude())) + "," 
           + String.valueOf(((location.getLongitude() * 100) % 100)) + " degrees"); 

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

      public void onProviderEnabled(String provider) {} 

      public void onProviderDisabled(String provider) {} 
      }; 

locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);

및 매니페스트에서 나는 이러한 권한 선언 :

은 GPS에 대한 코드는 MainActivity에있어

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/> 
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/> 
<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION" />

로그를 콜백에 넣으면 호출됩니까? –

이 작업을 수행 할 때 외부에 있습니까? 당신은 깜박이는 GPS 신호 대신 안정된 GPS 신호를 보았습니까? – Carnal

당신은 충분히 기다렸습니까? GPS는 특히 당신이 안에있는 경우 약간의 시간이 필요합니다 – EMarci15

GPS 공급자를 사용하여 위치를 검색하려고하는데 건물 내부에 있거나 GPS 수신이 좋지 않으면 onLocationChanged가 호출되지 않습니다.

Wi-Fi 또는 셀 타워에 대한 자동 폴백이 없습니다.

기준을 지정할 때도 사용중인 공급자 종류를 항상 확인하십시오.

Google은 Google Play 서비스를 통해 new Location APIs의 무리를 출시하여 사용자 위치 검색의 효율성을 높여 정확성과 배터리 수명을 향상 시켰습니다.

자습서 (다운로드 할 수있는 샘플 앱이 포함되어 있음) Retrieving the Current Location 자습서를 따르는 것이 좋습니다.
