錯誤Package xyz has mismatched uid: 10044 on disk, 10045 in settings存在文件夾/data/data/xyz/造成的。
在此消息文件夾中存在並具有與現在安裝的（10045）不同的所有者（10044）。它是由以前的不潔安裝引起的。
例如，以前的安裝失敗，出現一些錯誤，不要刪除創建的文件夾。
因爲在文件夾中可以從其他應用程序的數據android不能使用它。 PackageManager嘗試以不同的方式修復它，但如果不能這樣做 - 它會得到不同的應用程序目錄並顯示此消息。
更好的解決方案 - 安裝應用程序並清理刪除它。之後，再次安裝它。
另一種解決方案 - 在某些方面刪除文件夾/data/data/xyz/。可能是你需要這個根。從PackageManager
