Android 6.0即使拥有777 chmod权限也无法读取数据目录中的文件

Question

I have files which have chmod 777 permissions in my data/data/package_directory/here

I can't read them, like when I want to calculate crc32 or try to copy the file to SD Card with write external permission in manifest. I am targeting Android Lollipop so run time permissions are not required.

How to fix this? I can not even access files with 777 permission in my directory. I have granted root already to my App?

Error is:

open failed: EACCES (Permission denied)

Always, whatever I do.

Answer 1

In your emulator/device you should go to the Settings -> Applications -> (Your app) -> Permissions. Then enable the permissions for memory there
