Android gpsの場所が定期的に更新されない

Question

私は、サービスにgpsの場所を数秒ごとに更新するためにfusedlocation apiを使用しています。MainActivityでlocationSettings.Openを開くコードを記述しました。onResumeメソッドでサービスを開始します.java）。サービスクラスはブロードキャストを毎回送信します。場所は更新され、onResume（）メソッドで受信されます。場所の座標は一度取得してください。once.sendAmblnceGps（）メソッドは、場所がサーバーに送信される場所です。

GpsService.java：

public class GpsService extends Service implements GoogleApiClient.OnConnectionFailedListener, GoogleApiClient.ConnectionCallbacks { 
    com.google.android.gms.location.LocationListener locationListener; 
    LocationRequest mLocationRequest; 
    private static final long INTERVAL = 100* 50; 
    private static final long FASTEST_INTERVAL = 100 * 20; 
    GoogleApiClient googleApiClient; 
    boolean connected; 


    public GpsService() { 

     super(); 
    } 

    @Override 
    public void onCreate() { 
     super.onCreate(); 
     GoogleApiClient.Builder googleApiClientbuilder=new GoogleApiClient.Builder(GpsService.this).addConnectionCallbacks(GpsService.this).addOnConnectionFailedListener(GpsService.this).addApi(LocationServices.API); 
     googleApiClient=googleApiClientbuilder.build(); 
     googleApiClient.connect(); 
     Toast.makeText(getApplicationContext(),"service created",Toast.LENGTH_SHORT).show(); 
    } 

    protected void createLocationRequest() { 
     mLocationRequest = new LocationRequest(); 
     mLocationRequest.setInterval(INTERVAL); 
     mLocationRequest.setFastestInterval(FASTEST_INTERVAL); 
     mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY); 
     mLocationRequest.setSmallestDisplacement(100); 
    } 

    protected void startLocationUpdates() { 
     if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) { 
      // TODO: Consider calling 
      // ActivityCompat#requestPermissions 
      // here to request the missing permissions, and then overriding 
      // public void onRequestPermissionsResult(int requestCode, String[] permissions, 
      //           int[] grantResults) 
      // to handle the case where the user grants the permission. See the documentation 
      // for ActivityCompat#requestPermissions for more details. 
      return; 
     } 
       LocationServices.FusedLocationApi.requestLocationUpdates(
       googleApiClient, mLocationRequest, locationListener); 

     Log.d("TAG", "Location update started ..............: "); 
    } 

    @Override 
    public int onStartCommand(Intent intent, int flags, int startId) { 
     Log.e("Service Command", "Started"); 
     locationListener = new com.google.android.gms.location.LocationListener() 
     { 
      @Override 
      public void onLocationChanged(Location location) { 
       Intent intent = new Intent("location_updates"); 
       intent.putExtra("lat", location.getLatitude()); 
       intent.putExtra("longt", location.getLongitude()); 
       Log.e("location", "lat:" + " " + Double.toString(location.getLatitude()) + " " + "Longt:" + " " + Double.toString(location.getLongitude())); 
       sendBroadcast(intent); 
       } }; 
      return START_STICKY; 

    } 

    @Override 
    public void onDestroy() { 
     super.onDestroy(); 
     LocationServices.FusedLocationApi.removeLocationUpdates(googleApiClient,locationListener); 
     if(googleApiClient.isConnected()){ 
      googleApiClient.disconnect(); 
     } 
     Log.e("Service","Stopped"); 

    }

      googleApiClient.disconnect(); 
     } 
    } 

    @Override

Answer 1

あなたはmLocationRequest.setSmallestDisplacement(100);を指定しているので、あなたが持っている最初の位置更新の場所から少なくとも100メートルを移動する必要があります新しい場所の更新。
