GoogleApiClient: bağlı değil onConnected veya onConnectionFailed

Question

Yani, GoogleApiClient kullanarak son konumumu almaya çalışıyorum. Ben bir connect deyimi yürütüyorum, ancak onConnected ateş etmiyor, onConnectionFailed ateşleniyor. Herhangi bir fikir?

Açıklama: Bunu bir taklitçide çalıştırıyorum, gerçek bir aygıt değil. Emülatöre göz atmak işe yarıyor. Burada

     mLastLocation = LocationServices.FusedLocationApi.getLastLocation(
       mGoogleApiClient); 
     if (mLastLocation != null) { 
      mLatitudeText.setText(String.valueOf(mLastLocation.getLatitude())); 
      mLongitudeText.setText(String.valueOf(mLastLocation.getLongitude())); 
      TextView t=new TextView(this); 

      t=(TextView)findViewById(R.id.mLatitude); 
      t.setText(String.valueOf(mLastLocation.getLatitude())); 
      setContentView(mLatitudeText); 
     } 
    } 



    @Override 
    public void onConnectionSuspended(int i) { 

    } 


    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.menu_main, menu); 
     return true;

Answer 1

Geri arama işlemini buildGoogleApiClient() yöntemine kaydetmeniz gerekiyor.

Answer 2

deneyin sizin buildGoogleApiClient

 mGoogleApiClient = new GoogleApiClient.Builder(this) 
      .addApi(LocationServices.API) 
      .addConnectionCallbacks(this) 
      .addOnConnectionFailedListener(this) 
      .build(); 

bunu sadece müşterinize

   .addConnectionCallbacks(this) 
       .addOnConnectionFailedListener(this)
