[英]Android app restart after Google Play update

原文 2015-01-27 15:03:07 3 1 android/ google-play/ updates/ restart/ beta

I have just updated my app on Google Play (just in beta mode yet), and I was quite surprised that when I tested the update the app did NOT restart. 我刚刚在Google Play上更新了我的应用程序（还只是处于beta模式），当我测试更新后该应用程序没有重新启动时，我感到非常惊讶。 How is this possible? 这怎么可能？ For correct behaviour it should restart. 为了正确的行为，它应该重新启动。 (It uses Activities only.) （仅使用活动。）

What if I had significantly changed the app functionality? 如果我对应用程序功能进行了重大更改怎么办？ The old version would run until the user manually restarted the app? 旧版本将一直运行，直到用户手动重新启动该应用程序为止？

I didn't find a guide on updating Android apps. 我没有找到更新Android应用程序的指南。 (just user guides, but they are useless for me). （只是用户指南，但对我来说却毫无用处）。

1 个解决方案

I figured out what the problem was. 我发现了问题所在。 I am using a Nexus 7 device, with multiple users, and I had the app installed on both. 我正在使用Nexus 7设备，并且有多个用户，并且两个上都安装了该应用程序。 While the internal storage is different for these apps, the path for the App Expansion Files (shared-storage/Android/obb/package-name) is the same. 尽管这些应用程序的内部存储空间不同，但应用程序扩展文件的路径（shared-storage / Android / obb / package-name）相同。 This caused issues in the non- updated version, because it saw the updated Expansion File, and re-downloaded its own version again. 这会在未更新的版本中引起问题，因为它看到了更新的扩展文件，然后再次重新下载了自己的版本。

I think this is quite an issue of the OS, because the two user's versions should not interfere with each other at all. 我认为这是操作系统的一个相当大的问题，因为两个用户的版本完全不应该互相干扰。
