Why I get different Application.persistentDataPath?

I had built an android game in unity5.2.3.

When I log the persistentDataPath in my android, I get the path in “/data/user/0/mypackage”.
But the second day, when I build it in another PC, the same project log another path in “/storage/emulated/0/Android/data/mypackage”.

But the two project has no any different.(include the playersettings, all same.)

I try to copy one project to another pc and make the same build function.But it also the different persistentDataPath.

If its the different unity settings?Or somewhere I make wrong operate?

The problem has been resolved.
The reason is my Android SDK path has both sdk21 and sdk23.
Probably Unity use the higher one, and it`s the problem in sdk23.
It is solved when I remove the sdk23 folder.
