在我的android应用程序中使用GCM推送通知

Question

我想为我的android应用程序实现推送通知。我在网上查了一下，从androidhive.com看到一个很好的教程。我一步一步地跟着它，但最终它没有奏效。有7个PHP文件，我已经实现了服务器端。我在000webhost上创建了我的服务器，并创建了它所需的数据库。我的设备可以在我的应用程序服务器上成功注册，这些条目也可以在数据库中看到。但是，我的谷歌API控制台显示没有连接到任何设备。我觉得我的服务器和GCM之间的连接可能存在错误，但这只是一个猜测，我不知道真正的问题。 这里是我的7个PHP文件。

config.php 

    <?php 
    /**

    define("DB_PASSWORD", "(my_password)"); 
    define("DB_DATABASE", "a4307731_GCM");

Incase，你需要看看我从哪里得到的教程链接。这是 http://www.androidhive.info/2012/10/android-push-notifications-using-google-cloud-messaging-gcm-php-and-mysql/

Answer 1

的谷歌API控制台是不会告诉你任何东西，即使它的工作：

注：在谷歌API控制台资料for GCM未启用。您必须使用开发者控制台。 Source

您的服务器从疗法GCM服务器告诉你，如果你meesages被GCM接受的响应。如果他们是这样，问题不在于你的服务器代码，所以如果你没有在设备上得到消息，你应该在你的问题中包含客户端代码和清单。

Answer 2

嘿，你是否检查过卷曲电话？

是000webhost直接支持curl调用还是使用代理？

如果它使用代理，那么它不会发送消息到设备。

Answer 3

我也试过了android配置单元的教程，但它没有工作，然后我做了一些更多的谷歌，并找到这对我有效。
