GCM android推送通知總是顯示舊消息。意圖收到不正確

我有一個完美的GCM通知實現。但是，問題是一旦接收到的方法意圖收到消息，則顯示的消息始終是舊消息。 'extras.getString（「payload」）'總是顯示舊信息。我似乎無法弄清楚問題所在。GCM android推送通知總是顯示舊消息。意圖收到不正確

發送所述GCM通知的類是：

import android.app.Notification; 
import android.app.NotificationManager; 
import android.app.PendingIntent; 
import android.content.BroadcastReceiver; 
import android.content.Context; 
import android.content.Intent; 
import android.util.Log; 

public class C2DMMessageReceiver extends BroadcastReceiver { 
      @Override 
      public void onReceive(Context context, Intent intent) { 
          String action = intent.getAction(); 
          Log.w("C2DM", "Message Receiver called"); 
          if ("com.google.android.c2dm.intent.RECEIVE".equals(action)) { 
              Log.w("C2DM", "Received message"); 
              String payload = intent.getStringExtra("payload"); 
              Log.d("C2DM", "dmControl: payload = " + payload); 
              // TODO Send this to my application server to get the real data 
              // Lets make something visible to show that we received the message 
              createNotification(context, payload); 
          } 
      } 



      public void createNotification(Context context, String payload) { 
          NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE); 
          Notification notification = new Notification(R.drawable.icon, 
                  "Message sent!", System.currentTimeMillis()); 
          // Hide the notification after its selected 
          //notification.flags |= Notification.FLAG_AUTO_CANCEL; 
          notification.ledARGB = 0xff00ff00; 
          notification.ledOnMS = 300; 
          notification.ledOffMS = 1000; 
          notification.flags |= Notification.FLAG_SHOW_LIGHTS; 


          Intent intent = new Intent(context, MessageReceivedActivity.class); 
          intent.putExtra("payload", payload); 
          intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
          intent.putExtra("NotifID", 1); 
          PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,intent, 0); 
          notification.setLatestEventInfo(context, "Message","Message Recieved", pendingIntent); 
          notificationManager.notify(0, notification); 
      }

}

其中臨危通知消息的類是：

import android.app.Activity; 
import android.app.NotificationManager; 
import android.content.Context; 
import android.content.Intent; 
import android.net.Uri; 
import android.os.Bundle; 
import android.provider.MediaStore; 
import android.widget.TextView; 

public class MessageReceivedActivity extends Activity { 
      @Override 
      protected void onCreate(Bundle savedInstanceState) { 
          setContentView(R.layout.activity_result); 
          NotificationManager notificationManager = (NotificationManager) this 
                  .getSystemService(Context.NOTIFICATION_SERVICE); 
          //---cancel the notification--- 
          int id=getIntent().getExtras().getInt("NotifID"); 
          notificationManager.cancelAll();  
          Bundle extras = getIntent().getExtras(); 
          if (extras != null) { 
              String message = extras.getString("payload"); 
              if (message.equals("call")) { 
                  Intent intent = new Intent(Intent.ACTION_CALL); 
                  intent.setData(Uri.parse("tel:9916261960")); 
                  startActivity(intent); 
              } else if (message.equals("camera")) { 
                  Intent cameraIntent = new Intent(
                          MediaStore.ACTION_IMAGE_CAPTURE); 
                  startActivity(cameraIntent); 
              } else { 
                  if (message != null && message.length() > 0) { 
                      TextView view = (TextView) findViewById(R.id.result); 
                      view.setText(message); 
                  } 
              } 
          } 
          super.onCreate(savedInstanceState); 
      }

}

這裏，額外.getString（「有效載荷」）;始終保持第一次發送通知消息。

在創建掛起的意圖，使用FLAG_UPDATE_CURRENT

PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

否則舊的意圖沒有新的額外重用

工程。謝謝。 – jasdmystery

我有同樣的問題。但「FLAG_UPDATE_CURRENT」不適合我。我仍然收到舊信息。 – viji

適合我，謝謝 – TheMan

嘗試獲取內部

@覆蓋保護無效onNewIntent你的意圖（意圖）{

super.onNewIntent(intent); 

    Bundle extras = intent.getExtras(); 
    fromScreen = getIntent().getIntExtra("FROMSCREEN", 
      Config.SHARE_SCREEN_TAG); 
//enter code here

}
