推荐答案

请问Android应用工作作为客户端为您的服务器？如果是这样的话，我不建议你使用服务器端的推送更新通知。如果通知无法到达设备（据我所知，官方文件说，这是正常的行为），用户将拥有过时的版本。这是更好地检查新版本定期/在每个访问服务器，并下载/安装的APK这里解释 和<一个href=\"http://stackoverflow.com/questions/4604239/install-application-programmatically-on-android\">here.您可能还需要看看FDroid 的源$ C ​​$ C，其中包括服务器端和客户端机端的组件和可以获取，下载和应用程序数目安装更新。

Does Android application work as client for your server? If this is the case, I do not recommend you to use server-side pushes for update notifications. If notification fails to reach device (AFAIK, official documentation says, that this is normal behavior), user will have outdated version. It is better to check for new version periodically/on every access to server and download/install apk as explained here and here. You may also want to look at source code of FDroid, which consist of server- and client-side components and can fetch, download and install updates for number of applications.
