Package xyz has mismatched uid: 10044 on disk, 10045 in settings由存在文件夹引起的错误/data/data/xyz/。
在此消息文件夹中存在并且从现在安装 (10045) 具有不同的所有者 (10044)。它是由以前的不干净安装引起的。
例如，以前的安装失败并出现一些错误，并且不删除创建的文件夹。
因为文件夹中可以是来自其他应用程序的数据 android 不允许使用它。PackageManager尝试以不同的方式修复它，但如果不能这样做 - 它会获取应用程序不同的目录并显示此消息。
更好的解决方案 - 安装应用程序并清除它。之后再次安装它。
另一种解决方案 - 以某些方式删除文件夹/data/data/xyz/。可能你需要root。
