执行GCM客户端时发生未知错误和警告 [英] Unknown errors and warnings while implementing GCM client side

问题描述

我正在尝试实施 Github
，但无法在我的 MyGcmListenerService.java

中收到通知

当我通过在我的android studio logcat中生成的日志时，发现此警告和错误消息

问题

• 如何解决部分或全部错误或警告？


• 它们是否与从GCM服务器收到通知失败有关？ p>所述错误和问题与接收gcm通知无关。为我的情况。从gcm连接服务器收到的gcmid未保存在数据存储区中。负责保存它的实体实施得很糟糕，因此我没有收到来自GCM连接服务器的消息或通知。
  
  
  
  
  

  • 确保从连接服务器收到的gcmId很好的保存在你的应用服务器中（我使用objectify来实现这一点）

  类，以便在重要阶段通过打印日志（消息）来跟踪您的实现。例如当你收到gcmid（你可以在前端实现这个，因此使用 Log.d（）方法），如果gcmid已经保存到你的应用服务器上（这里你使用实体要做到这一点，它在这里你使用 Logger class ，因为这发生在后端模块）。

  Question

  • how can i solve some or all or of this errors and warnings?
  • Do they have to do with my failure to receive notifications from GCM server ?

  解决方案

  The stated errors and problems have nothing to do with receiving gcm notifications. for my case. gcmid received from gcm connection server wasn't being saved at datastore. the entity responsible for saving it was badly implemented thus i coundn't receive messages or notifications from GCM Connection servers.

  • Make sure gcmId received from connection servers is well saved in your app server.(i use objectify to achieve this)

  • Also make use of Logger class at your backend module in order to track your implementation by printing out logs(messages) at important stages. e.g when you receive gcmid (you can implement this at the frontend thus use Log.d() method), if gcmid have been saved to your app server( here you use entities to do that and its here where you use Logger class because this takes place at backend module).
