问题描述：

Caused by: java.lang.UnsatisfiedLinkError:

Couldn't load mupdf from loader dalvik.system.PathClassLoader[dexPath=/system/framework/android.test.runner.jar:/data/app/com.hd_51talk.dasheng-1.apk,libraryPath=/data/app-lib/com.hd_51talk.dasheng-1]:
findLibrary returned null

从报的错误可以查看出，不能正常加载 mupdf.so的文件

从网友http://tjlibaoh.blog.163.com/blog/static/21122641320140188290830/ 这个帖子里面分析出来，可能也是因为这个原因造成的不能成功加载进来**.so文件

之前错误时的目录结构



修改后的目录结构，把armeabi或armeabi-v7a 的文件复制到新创建的x86文件夹下，问题解决
