Dynamically load shared library from sd card

Question

I want to dynamically load library from SD card, with dlopen, but when I do it, get error: dlopen failed: couldn't map "/storage/emulated/0/Documents/Tests/armeabi-v7a/libtest.so" segment 2: Operation not permitted

When i use it for internal storage it's work. What can i do to solve this problem?

This is disallowed by Android's security policy. Anyone can write to that location, so loading code from it is an easily exploitable attack vector.

Thanks. But if copy from sd card location to internal location it's work – Sinigr Jun 07 '16 at 08:30
To a controlled location though, right? If you're on a rooted device then lots of the security restrictions are going to be pretty much neutered... – Dan Albert Jun 08 '16 at 21:35
