在android中未接收推送通知
您好，在我的应用程序中，我使用此站点使用gcm concept androidhive.info发送推送通知。我在localhost-to-server中测试，在检测到仿真器注册id并发送通知后，它工作正常，没有显示任何设备。现在，详细信息也存储在本地数据库中 现在我的问题是，我正在从服务器接收任何推送通知在android中未接收推送通知,android,google-cloud-messaging,Android,Google Cloud Messaging,您好，在我的应用程序中，我使用此站点使用gcm concept androidhive.info发送推送通知。我在localhost-to-server中测试，在检测到仿真器注册id并发送通知后，它工作正常，没有显示任何设备。现在，详细信息也存储在本地数据库中 现在我的问题是，我正在从服务器接收任何推送通知 有谁能帮助我并重新爱上它吗 AlertDialogManager.java： public class AlertDialogManager { public void showA
