我们正在尝试在手机中制作自定义启动器默认值。由于它需要系统级别权限（放置窗口小部件），我们将其放在System / Priv-App中，并且它最终正常工作。问题是它不是从播放商店的新版本更新。 - 在下载更新后，我们在安装过程开始时获得错误505
提前谢谢！ 布尔 y
we're trying to make our custom launcher default one in our phone. Since it needs system level permissions (placing widgets) we placed it in system/priv-app, and it finally works ok. Problem is that it is not updateing with new version from Play Store. - we're getting error 505 after downloading update, on start of install process
thank you in advance! br Y
If the "pre-installed app" uses the same signature as the one on Google Play, it of course can be updated that way xe2x80x93 same as e.g. Google Maps and other pre-installed stuff is.
Note that, however, those updates would not be integrated in the ROM, but go into user-space xe2x80x93 "overlaying" the pre-installed version. This gives users the advantage of being able to "uninstall updates", but at the cost of "double space" (the original APK remains in
/system xe2x80x93 not that they could use that space otherwise, though).
I found the Google Play is re-signing my package. This used to cause a signatures mismatch. The solution is to install to /system/priv-app/ an apk downloaded from GP (that has been already re-signed).
