Question

I want to make a pdf viewer program in android phone. So, I purchased the mupdf library. I built the mupdf c++ classes and have 'libmibookreader.so' file. And I also compiled the native function classes. Then, I tried to run the application , but I have some errors.

Answer 1

我认为你没有正确加载库，或者你可能没有在System.load("libname");正确地给出名称System.load("libname");

Answer 2

What is your android version? on 2.1 and before, the lib libjnigraphics.so is missing and the mupdflib need it
