設備自動從GCM取消註冊，出現空錯誤

Question

我正在用Google Cloud Messaging librarys構建應用程序。儘管帶有API 15的設備工作良好，但設備（API 10）仍然存在問題。

API 10的問題， 首先，設備能夠註冊GCM並能夠在註冊期間生成註冊ID。但是，當消息從服務器發送到設備時，應用程序會自動調用GCMintent service class中的onUnregistered方法，並且還會爲該錯誤提供空值。如下所示

以下是我的代碼。

// This is the GCMIntentService class 

    public class GCMIntentService extends GCMBaseIntentService { 
     private static final String TAG = "GCMIntentService"; 


     public GCMIntentService() { 
      super("IntentService"); 
     } 

     /** 
     * Method called on device registered 
     **/ 
     @Override 
     protected void onRegistered(Context context, String registrationId) { 
      Log.i(TAG, "Device registered: regId = " + registrationId); 

     } 
     /** 
     * Method called on Receiving a new message 
     * */ 
     @Override 
     protected void onMessage(Context context, Intent intent) { 
      Log.i(TAG, "Received message"); 

     } 

     /** 
     * Method called on device un registred 
     * */ 
     @Override 
     protected void onUnregistered(Context context, String registrationId) { 
      Log.i(TAG, "Device unregistered from the app"); 

     } 


      /** 
      * Method called on receiving a deleted message 
      * */ 
      @Override 
      protected void onDeletedMessages(Context context, int total) { 
       Log.i(TAG, "Received deleted messages notification"); 

      } 

      /** 
      * Method called on Error 
      * */ 
      @Override 
      public void onError(Context context, String errorId) { 
       Log.i(TAG, "Received error: " + errorId); 
       //displayMessage(context, getString(R.string.gcm_error, errorId)); 
      } 

      @Override 
      protected boolean onRecoverableError(Context context, String errorId) { 
       // log message 
       Log.i(TAG, "Received recoverable error: " + errorId); 

       return super.onRecoverableError(context, errorId); 
      } 


     } 




    /**

請問我有什麼需要做的嗎？如果有人能幫助我，我將不勝感激。謝謝

GCMBaseIntentService已被棄用，您應該使用GcmListenerService來代替。 GcmListenerService應該在API 10上工作。請參閱this quickstart以瞭解如何使用它。
