Solution 1:[1]

It is always recommended not to use '/' or '\' chars hardcoded anywhere. Instead please try using Path.DirectorySeparatorChar (See Unity docs).

In this case it should be:

xml.Load(Application.persistentDataPath + Path.DirectorySeparatorChar + "PlayerData.xml");

Then you can be certain that on all kind of devices or platforms at least the path will be correct.

Solution 2:[2]

Application.persistentDataPath have two paths base on your Write Access setting, you can find it at Build Setting > Player Setting > Other Settings, by default, it is internal Only. means that the path should be point to /data/data/com.your.appid/files which is for development only, user cannot find this files without root android device.

if you set the Write Access as External(SD Card) or add WRITE_ EXTERNAL_STORAGE permission into AndroidManifest.xml, Application.persistentDataPath will point to Android/file/com.your.appid/files of your sd card.

I had same problem and this fixed it!
