android – 软件包xyz不匹配uid：10044在磁盘上,10045在设置中

在此消息文件夹中存在并且具有从现在开始安装的不同所有者(10044)(10045).它是由以前的不洁安装引起的.

例如,先前安装失败并出现一些错误,并且不删除创建的文件夹.

因为在文件夹中可以将来自其他app的数据安卓不能使用它. PackageManager尝试以不同的方式修复它,但如果不能这样做 – 它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.之后再安装一次.

另一种解决方案 – 在某些方面删除文件夹/ data / data / xyz /.可能你需要这个根.
