Android應用程序中的GCM消息接收

Question

我正在使用GCM庫在我的Android應用程序中實現推送通知。 問題是，即使認爲，服務器端（發送GCM消息）和Android註冊都很好，似乎我的Android應用程序不會收到發送的消息！ 我搜索了很多，試圖通過不同的方式解決它，但仍然沒有。所以，這是我的應用程序文件，並非常感謝您的幫助。

• 主要：

  public class Login extends Activity implements OnClickListener{ 
  @Override 
  protected void onCreate(Bundle savedInstanceState){ 
  super.onCreate(savedInstanceState);   
  setContentView(R.layout.activity_login); 
  btnGo = (Button) findViewById(R.id.btnenter); 
  btnGo.setOnClickListener(this); 
  } 
  public boolean onCreateOptionsMenu(Menu menu) { 
  // Inflate the menu; this adds items to the action bar if it is present. 
  getMenuInflater().inflate(R.menu.login, menu); 
  return true; 
  } 
  
  public void onClick(View v) { 
      if (v==btnGo){ 
       Intent intent = new Intent(Login.this, GCMIntentService.class); 
       intent.putExtra("val", "coucou"); 
       startService(intent); 
  
       Intent intent1 = new Intent(Login.this, MedicoAppliMain.class); 
       startActivity(intent1); 
         } 
      } 
  }

• GCMIntentService：

  package com.example.medicoappli; 
  
  import com.google.android.gcm.GCMBaseIntentService; 
  import android.content.Context; 
  import android.content.Intent; 
  import android.util.Log; 
  import android.widget.Toast; 
  
  
  public class GCMIntentService extends GCMBaseIntentService { 
  
  private static final String TAG = "GCMIntentService";     
  
  public GCMIntentService() { 
      super("329261430680"); 
  } 
  
  
  private static void generateNotification(Context context, String message) { 
  
      Toast toast = Toast.makeText(context, "Vous avez un Messsage GCM", 3); 
      toast.show(); 
  } 
  
  @Override 
  protected void onError(Context arg0, String arg1) { } 
  
  @Override 
  protected void onMessage(Context arg0, Intent arg1) { 
  
      Log.d("GCM", "RECEIVED A MESSAGE"); 
      Log.d("val", arg1.getStringExtra("val")); 
      // Get the data from intent and send to notification bar 
      //generateNotification(arg0, arg1.getStringExtra("message")); 
  } 
  
  @Override 
  protected void onRegistered(Context arg0, String arg1) { } 
  
  @Override 
  protected void onUnregistered(Context arg0, String arg1) {  } 
  
  } 
  

  • 服務器端：

    package Server_Side; 
    
    import java.util.ArrayList; 
    
    import com.google.android.gcm.server.Message; 
    import com.google.android.gcm.server.MulticastResult; 
    import com.google.android.gcm.server.Result; 
    import com.google.android.gcm.server.Sender; 
    import java.net.Authenticator; 
    import javax.xml.ws.BindingProvider; 
    
    
    
    class Notify { 
    public static void main(String args[]) { 
    try { 
    Sender sender = new Sender("AIzaSyDjIcQt6mff7ujIvqWtwKVuVEYmbUBy0I0"); 
    
        // use this line to send message with payload data 
        Message message = new Message.Builder() 
          .collapseKey("1") 
          .timeToLive(3) 
          .delayWhileIdle(true) 
          .addData("message","this text will be seen in notification bar !!") 
          .build(); 
    
        // Use this code to send to a single device (clé associé à l'application) 
        Result result = sender.send(message,"APA91bGJxJxgtjmdKV1Ws766Cwr8ZaVKSn0Q7F17OQccI8sGhDWYo2pJCW0znS6qfEsy5ui1CSq9_ihGy9UKvoV9yqQW3AqP1c25ghLLBqt6nsPGEJE0qqHMhqIrhvVVDRy29R0gqtVZV-kJmicW5K8T_zOFO9reRUeADqTcxedKyjHhwFkxHOA",1);

我沒有看到任何代碼將您的應用程序註冊到GCM並將註冊ID傳遞到您的服務器。

我看不出在onClick啓動意圖服務點：

Intent intent = new Intent(Login.this, GCMIntentService.class); 
intent.putExtra("val", "coucou"); 
startService(intent); 

這種服務只能由GCMBroadcastReceiver啓動時，無論是註冊或消息到達。

編輯：

我也會改變，從清單中的服務項：

<service android:process=":service" android:name="GCMIntentService"></service>

到：

<service android:name="com.example.medicoappli.GCMIntentService"></service>

或至少：

<service android:name=".GCMIntentService"></service>
