android – GCM推送通知图标

{
    "to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...","notification" : {
      "body" : "great match!","title" : "Portugal vs. Denmark","icon" : "myicon"
    }
  }

使用您的应用程序图标,如.setsmallIcon(R.drawable.appicon),其中appicon是您的drawable文件夹中的.png文件

或者使用此代码：

NotificationCompat.builder notificationBuilder = (NotificationCompat.builder) new NotificationCompat.builder(this)
         .setsmallIcon(R.drawable.icond)
         .setContenttitle("Start Launcher")
         .setContentText(messagE)
         .setAutoCancel(true)
         .setOngoing(true)
         .setWhen(System.currentTimeMillis())
         .setContenTintent(pendingIntent);

   notificationmanager notificationmanager = (notificationmanager) getApplicationContext().getSystemservice(Context.NOTIFICATION_serviCE);

   notificationmanager.notify(ID_NOTIFICATION,notificationBuilder.build());
