android - 位置情報サービス GPS 強制終了

Question

こんにちは、私は最適な場所を特定し、それを番号に SMS で送信するアプリを開発しています。ネットワークの場所で問題なく動作しますが、GPSまたは基準クラスで場所を特定したい場合、強制的に閉じられます!! 私を助けてくれてとても親切です。

package ir.M410.toolkit;

import android.app.Service;
import android.content.Intent;
import android.location.Criteria;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.os.IBinder;
import android.telephony.SmsManager;
import android.util.Log;



public class LocationFinder extends Service implements LocationListener{

double lat ,lon ;
@Override
public IBinder onBind(Intent arg0) {
    return null;
       }

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    // We want this service to continue running until it is explicitly
    // stopped, so return sticky.


    LocationManager mlocationManager = (LocationManager)        getSystemService(LOCATION_SERVICE);
    Criteria criteria = new Criteria();
    criteria.setAccuracy(Criteria.ACCURACY_FINE);
    criteria.setPowerRequirement(Criteria.POWER_MEDIUM);
    String locationprovider = mlocationManager.getBestProvider(criteria, true);
    Location mlocation = mlocationManager.getLastKnownLocation(locationprovider);


      lat = mlocation.getLatitude ();
      lon = mlocation.getLongitude ();

      Log.i("Geo_Location", "Latitude: " + lat + ", Longitude: " + lon);

      SmsManager sms = SmsManager.getDefault();
        sms.sendTextMessage("+11231233213", null,"https://maps.google.com/maps?q="+lat+","+lon, null, null);



        //  SmsManager sms = SmsManager.getDefault();
    //sms.sendTextMessage(MainActivity.senderNum, null,"  "+"lat:"+lat+"  "+"lon:"+lon, null, null);
 //stopSelf();
          return START_NOT_STICKY;
}

@Override
public void onLocationChanged(Location location) {
    // TODO Auto-generated method stub

     lat= location.getLatitude();
    lon =location.getLongitude();

    Log.i("Geo_Location", "Latitude: " + lat + ", Longitude: " + lon);
  //  stopSelf();
}

@Override
public void onProviderDisabled(String provider) {
    // TODO Auto-generated method stub

}

@Override
public void onProviderEnabled(String provider) {
    // TODO Auto-generated method stub

}

@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
    // TODO Auto-generated method stub

}


@Override
public void onDestroy() {
    super.onDestroy();

}
}

これは私のマニフェストです：

[編集済み] null でないことを確認するコード:

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    // We want this service to continue running until it is explicitly
    // stopped, so return sticky.


    LocationManager mlocationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
    Criteria criteria = new Criteria();
    criteria.setAccuracy(Criteria.ACCURACY_FINE);
    criteria.setPowerRequirement(Criteria.POWER_MEDIUM);
    String locationprovider = mlocationManager.getBestProvider(criteria, true);
    if(mlocationManager.getLastKnownLocation(locationprovider)!=null){
    Location mlocation = mlocationManager.getLastKnownLocation(locationprovider);


      lat = mlocation.getLatitude ();
      lon = mlocation.getLongitude ();

      Log.i("Geo_Location", "Latitude: " + lat + ", Longitude: " + lon);

      SmsManager sms = SmsManager.getDefault();
        sms.sendTextMessage("+11231233213", null,"https://maps.google.com/maps?q="+lat+","+lon, null, null);

    }

そして、大丈夫で、強制的に閉じることはできませんが、データが受信されません。常にnullです!!
