Hello, I’ve successfully deployed an empty C++ project to Android, so now I’m trying to do the same with my main project, but nope… Here’s the LogCat output, any ideas?

// Edit

So I’ve found out that it’s happening on Samsung Galaxy S3 when I use custom GameInstance. On HTC M8 the error doesn’t exist.
              Hi Kosmo,
This really is the NDK API Level set to above android-19 causing the problem.  Some standard functions (like atof) were moved from static inline to libc.so starting with android-21.  Only Lollipop and above have the libc.so with the functions which is why it is failing in dlopen.
If you have checked the NDK API Level is actually set to android-19, I’d next check to make sure it recompiled.  Try turning on “Full Rebuild” in the Project Settings Packaging section.  You should see it recompile your source files when you package.
