android - Android：推送通知

Question

我正在开发一个应用程序。在该应用程序中，我正在使用 GCM（推送通知）。

我接受了这个Link 1的帮助。

我成功实现了客户端代码。

现在要发送通知，我使用以下链接：

链接 2

但问题是我可以收到通知，但是当我点击它时没有任何反应。

我应该怎么做，以便如果用户点击通知网页或更新页面等打开。

我使用了与该链接中给出的相同代码。到目前为止没有进行任何更改。

我在我的应用程序中间。所以请指导我并提出您宝贵的建议。

此功能在您的主要活动中调用。

public void registerClient() {

        try {
            // Check that the device supports GCM (should be in a try / catch)
            GCMRegistrar.checkDevice(viewLogin);

            // Check the manifest to be sure this app has all the required
            // permissions.
            GCMRegistrar.checkManifest(viewLogin);

            // Get the existing registration id, if it exists.
            regId = GCMRegistrar.getRegistrationId(viewLogin);

            if (regId.equals("")) {

                registrationStatus = "Registering...";

                // register this device for this project
                GCMRegistrar.register(viewLogin, GCMIntentService.PROJECT_ID);
                regId = GCMRegistrar.getRegistrationId(viewLogin);

                registrationStatus = "Registration Acquired";

                // This is actually a dummy function. At this point, one
                // would send the registration id, and other identifying
                // information to your server, which should save the id
                // for use when broadcasting messages.

            } else {

                registrationStatus = "Already registered";

            }
            Log.d(TAG, regId);
            sendRegistrationToServer();
        } catch (Exception e) {

            e.printStackTrace();
            registrationStatus = e.getMessage();

        }

        Log.d(TAG, registrationStatus);


    }
