매시간 백그라운드에서 위치 확인

Question

앱이 매시간 (앱이 실행되지 않을 때) 사용자의 위치를 ​​확인하고 그 시간의 위치가 이전에 기록 된 위치에서 100 마일 이상 떨어져있는 기능을 만들어야합니다. , api를 호출하여 백엔드에서 사용자의 위치를 ​​업데이트하십시오. 이것은 물론 배터리/전력 소비를 최소화하기 위해 고려됩니다.

저는 계속해서 운영되는 서비스로 일한 적이 없습니다. 이것을 달성하기위한 최선의 방법은 무엇입니까?

public class MyService extends Service 
{ 
private static final String TAG = "BOOMBOOMTESTGPS"; 
private LocationManager mLocationManager = null; 
private static final int LOCATION_INTERVAL = 1000 * 60 * 60; // 1 hour 
private static final float LOCATION_DISTANCE = 160935f; // 100 miles 

private class LocationListener implements android.location.LocationListener 
    { 
    Location mLastLocation; 

    public LocationListener(String provider) 
    { 
     Log.e(TAG, "LocationListener " + provider);

    } 
} 

@Override 
public void onDestroy() 
{ 
    Log.e(TAG, "onDestroy"); 
    super.onDestroy(); 
    if (mLocationManager != null) { 
     for (int i = 0; i < mLocationListeners.length; i++) { 
      try { 
       mLocationManager.removeUpdates(mLocationListeners[i]); 
      } catch (Exception ex) { 
       Log.i(TAG, "fail to remove location listners, ignore", ex); 
      } 
     } 
    } 
} 

private void initializeLocationManager() { 
    Log.e(TAG, "initializeLocationManager"); 
    if (mLocationManager == null) { 
     mLocationManager = (LocationManager) getApplicationContext().getSystemService(Context.LOCATION_SERVICE); 
    } 
} 
}
