GCM通知メッセージをAndroidのアクティビティに送信するにはどうすればよいですか？

Question

説明： 私はGCMを使用してusers.Everythingに通知を送信しています。私はpush_messageの残りの部分を作成するサーバー側のプログラミングを作成し、すべてのことが行われます。

通知をクリックすると、このメッセージが自分のアクティビティに表示されます。

自分のアクティビティでメッセージを開くにはどうすればよいですか？

Answer 1

投稿したコードは、サーバー用のデバイスをGCMに登録するIntentServiceです。

あなたはGCMからメッセージを受信する必要があるコードをここにされています。基本的に、あなた自身のGcmListenerServiceを作成する必要が

https://github.com/googlesamples/google-services/blob/master/android/gcm/app/src/main/java/gcm/play/android/samples/com/gcmquickstart/MyGcmListenerService.java#L43-L69

。

すべてのサービスと受信者をAndroidManifest.xmlに入れることを忘れないでください。

<!-- [START gcm_receiver] --> 
    <receiver 
     android:name="com.google.android.gms.gcm.GcmReceiver" 
     android:exported="true" 
     android:permission="com.google.android.c2dm.permission.SEND" > 
     <intent-filter> 
      <action android:name="com.google.android.c2dm.intent.RECEIVE" /> 
      <category android:name="your package" /> 
     </intent-filter> 
    </receiver> 
    <!-- [END gcm_receiver] --> 

    <!-- [START gcm_listener] --> 
    <service 
     android:name=".MyGcmListenerService" 
     android:exported="false" > 
     <intent-filter> 
      <action android:name="com.google.android.c2dm.intent.RECEIVE" /> 
     </intent-filter> 
    </service> 
    <!-- [END gcm_listener] --> 
    <!-- [START instanceId_listener] --> 
    <service 
     android:name=".MyInstanceIDListenerService" 
     android:exported="false"> 
     <intent-filter> 
      <action android:name="com.google.android.gms.iid.InstanceID"/> 
     </intent-filter> 
    </service> 
    <!-- [END instanceId_listener] --> 
    <service 
     android:name=".GcmIntentService" 
     android:exported="false"> 
    </service> 

Answer 2

GcmListenerServiceを実装するサービスを1つ作成するだけで済みます。

public class EMSListenerService extends GcmListenerService { 

    private static final String TAG = "ems_service"; 

    @Override 
    public void onMessageReceived(String from, Bundle data) { 
     super.onMessageReceived(from, data); 

     Display.log(TAG, "EMS received"); 

    } 
} 

そして、あなたはあなたがLocalBroadcastManager.getInstance(context).sendBroadcast(intent);
