Question

问题是我的GCM消息到达我的应用程序，但没有（自动）显示在屏幕上。

07-06 21:33:11.564 11269-11530/com.example.myapp D/MyGcmListenerService: Message: null

我收到的代码是：

public class MyGcmListenerService extends GcmListenerService {
    public static final String TAG = MyGcmListenerService.class.getSimpleName();

    @Override
    public void onMessageReceived(String from, Bundle data) {
        Log.d(TAG, "bundle: " + data);
        String message = data.getString("message");
        Log.d(TAG, "From: " + from);
        Log.d(TAG, "Message: " + message);
        ...

发送代码（使用node-gcm）是：

  var message = new ngcm.Message({
        priority: 'high',
        contentAvailable: true,
        restrictedPackageName: "com.example.myapp",
        data: {
                key1: 'message1',
                key2: 'message2'
        },
        notification: {
                title: "Hello, World",
                icon: "ic_launcher",
                body: "This is a notification that will be displayed ASAP."
        }
  });

我曾尝试使用contentAvailable和restrictedPackage，但没有区别。

我的问题是：

我的接收代码是否需要在消息到达时创建屏幕通知，或者应该由Android为我做这个（我相信）？
示例代码说捆绑包应该包含data.getString("message");，但我的应用程序将此视为空。为什么？

要自动显示gcm通知，您的推送消息json格式应与此相同

"notification" : {
            "body" : "great match!",
            "icon" : "ic_launcher.png",
            "title" : "Portugal vs. Denmark"
                }

是否应该通过Android显示到达的GCM消息？
