Fused Location Api位置

Question

我已經使用Fused Location api獲取經度和緯度，但問題在於itsit的說法，谷歌api客戶端isntisn't連接，但我沒有。我不知道我錯在哪裏，幫助我。

我飛濺的活動，其中II現在用電熔阿比::

注:: GPS追蹤器是這裏的班級，我用它使用我還沒有在節目中我用它的位置經理。我只是用它來檢查Gps是打開還是關閉。

我也在manifest文件中添加了所有權限。

谷歌最近發佈了一個新的API，它使得這個過程變得更容易，而且你不再需要GoogleApiClient。我強烈建議你改用這個API。

請參閱下面的示例以瞭解如何使用它。

FusedLocationProviderClient client = LocationServices.getFusedLocationProviderClient(context); 
client.requestLocationUpdates(locationRequest, pendingIntent) 
     .addOnCompleteListener(task -> { 
      Log.d("requestLocationUpdates", "result: " + task.getResult()); 
     }) 
     .addOnFailureListener(e -> { 
      String errorMessage; 
      if (e instanceof ApiException) { 
       errorMessage = ((ApiException) e).getStatusMessage(); 
      } else { 
       errorMessage = e.getMessage(); 
      } 
      Log.d("requestLocationUpdate", "failed: " + errorMessage); 
     }); 

在你的情況可能與this取代context指你的活動，而不是一個方面的參考。

pendingIntent是PendingIntent實例，它定義瞭如何處理收到的位置更新。
