Are you testing it on a real device?

Thanks for the reply
on real device works
but it is very slow
Is there a bookshelf that advises me to read the pdf?

The error from the first post is related to the native library (.so) used by this library. Apparently it doesn't include a x86 binary so it doesn't work with the emulator.
