更新的Android应用程序，不用重启设备 [英] Update Android application without restarting the device
问题描述
我有一个专用的Android设备上运行的全天候的应用程序。应用程序是在谷歌播放设置为自动更新。该应用程序下载并安装没有任何问题。
I have an application that is running 24/7 on a dedicated android device. The app is configured in Google Play to update automatically. The app downloads and installs without any issues.
我想弄清楚的部分是：应用程序需要认识到出现了下载和安装谷歌播放，并随后应停止更新，并重新启动本身
The part I am trying to figure out is: the app needs to recognize there has been an update downloaded and installed by Google Play and subsequently should stop, and restart itself.
可能？
推荐答案
毫无意义，因为你安装的（旧）应用程序被更新之一，这也意味着旧的被杀死，然后再覆盖代替。如果你需要知道你是新的，使每个应用即保存它的版本code。在启动检查存储的版本code对包的版本code和采取相应的行动。
Quite pointless, as your installed (old) application is replaced by updated one, which also means old one is being killed first, then overwritten. If you need to know you are "new" one, make each app i.e. store its versionCode. On launch check stored versionCode against package versionCode and act accordingly
