我开始研究pdf渲染。我需要打开应用程序内部的pdf文件，我查看android中可用的lib如droidreader，apv等所有工作都很慢并尝试将pdf转换为图像然后显示。然后我选择apdfviewer，我安装apk工作正常，但svn签出代码显示错误登录

请建议是否有其他好的库？确实需要为它安装NDK 我是android新手，提前谢谢

答案 0 :(得分：3)

它表明你的项目中没有JNI文件夹。你可能没有它的本机库文件（“example.so”）。 （.so）是库文件的扩展名。 建立这个.so文件你必须需要android NDK＆amp;一个名为“cygwin”的软件，它有助于从JNI文件夹构建本机文件
