Can you confirm that the TPK exists on the device?

I would use the File.exists() method to confirm it is on the device at that location:

File | Android Developers

Alexander thanks for your answer,

Yes, i use File to check if File.exists(),  i don't know was the problem,

my solution was back to android 22 and it work; the problem is with android 23.

[AlexanderNohe1]

If you are having issues at API version 23 it sounds like you are not giving permission to "dangerous" permissions.

This link should explain dangerous permissions:

System Permissions | Android Developers

This link would show how to request the permissions at runtime for external storage which would circumvent a possible dangerous permissions error:

android - Storage permission error in Marshmallow - Stack Overflow

Does this help?
