Android位置服務被殺

我有一個Android的位置偵聽器的問題。由於某種原因，它會停下來並被殺死。Android位置服務被殺

讓我們從一開始就着手。我有一個活動將啓動GPS。

private void CheckEnableGPS() { 
    LocationManager manager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); 
    //  String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED); 
    if (manager.isProviderEnabled(LocationManager.GPS_PROVIDER)) { 
     startGPS(); 
    } else { 
     buildAlertMessageNoGps(); 
    } 

} 

private void startGPS() 
{ 
    Toast.makeText(GPSActivity.this, "GPS Enabled", Toast.LENGTH_LONG).show(); 
    getApp().startGPSMonitor(); 
}

首先，我將GPSService綁定到我的應用程序。

bindService(new Intent(this, GpsService.class), mGpsServiceConnection, Context.BIND_AUTO_CREATE);

現在我只啓動一個服務，而不是結合它

startService(new Intent(this, GpsService.class));

的GPSService類：

@Override 
public void onCreate() { 
    super.onCreate(); 
    Log.d(MobileConnectorApplication.APPLICATION_TAG, "Started GPS Service"); 
    LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); 
    if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) { 
     locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, THIRTY_SECONDS, 0, this); 
    } else if (locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)) { 
     locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, THIRTY_SECONDS, 0, this); 
    } 
} 

@Override 
    public int onStartCommand(Intent intent, int flags, int startId) { 
     return START_STICKY; 
    } 

@Override 
public void onLocationChanged(Location location) { 
    MobileConnectorApplication app = ((MobileConnectorApplication) getApplication()); 
    Location oldLocation = app.getLastGpsLocation(); 

    if (isBetterLocation(location, oldLocation)) { 
     updateLocation.latitude = (float) location.getLatitude(); 
     updateLocation.longitude = (float) location.getLongitude(); 
     updateLocation.user = app.getLoggedInUser(); 

     try { 
      updateLocation.execute(); 
      app.setLastGpsLocation(location); 
     } catch (IOException e) { 
      Log.e(MobileConnectorApplication.APPLICATION_TAG, "GPSSERVICE - Sending action failed", e); 
     } catch (HttpException e) { 
      Log.d(MobileConnectorApplication.APPLICATION_TAG, "GPSSERVICE - Httpexception", e); 
     } 
     notifyBroadCastListeners(location); 
    } 
}

我需要這全天候運行，以每30秒更新。不要談論電池消耗等等，因爲這對我來說不是問題。我試過在這個服務的oncreate事件中聲明一個創建的wakelock。它似乎沒有幫助。我確實讀過這個位置偵聽器應該有它自己的喚醒鎖？這是真的？我需要在其他地方聲明一個喚醒鎖嗎？

有沒有人可以幫助我做到這一點？

欲瞭解更多信息，我得到了一些日誌，其中locationprovider被殺害。另外，我的應用程序是否被回收？（我需要重新登錄）

您應該閱讀有關service的生命週期。當系統需要更多資源時，他們可能會關閉。

有以下幾種解決方案：您可以使用startForgraound()來防止系統回收它。或者你可以聽系統事件來開始你的服務。例如，當用戶打開設備，當用戶將設備充電或其他任何東西時。

startforeground似乎已經做到了。謝謝！ – Robin
