【问题讨论】：

从您的 .Net 应用程序发送消息的请求格式是什么？
嗨，很抱歉回复晚了，我的 .net 在 c# 中
您是否正在创建将 GCM 消息发送到设备的请求？在任何情况下，您都没有使用推荐的在 Android 上使用 GCM 的方式，请查看此快速入门并将其用作您的应用程序的基础。 github.com/googlesamples/google-services/tree/master/android/…
谢谢！但是我已经从使用 GCM 切换到 PARSE 来发送推送通知，我可以将通知从解析服务器发送到我的 android 手机，我仍在尝试找出一种方法将通知从 asp.net c# 发送到我的 android 手机使用解析

标签： java android eclipse google-cloud-messaging

【解决方案1】：

从你的logcat来看，说明你需要做如下：

在您的Android Manifest中添加以下标签作为元素的子元素：

<meta-data android:name="com.google.android.gms.version"
    android:value="@integer/google_play_services_version" />

您可以在AndroidManifest 文件中添加</receiver> 和</application> 之间的行。

【讨论】：

这是安卓模拟器问题。要解决此问题，只需禁用 Android 设置中的所有声音（尤其是“触摸声音”）。
