android - 将 Mupdf 库用于 pdfrenderer 不起作用

Question

我在 MuPdf 库上工作了很长时间，在创建 libmupdf.so 文件并在 Cygwin 和 android-ndk 上工作后，我终于能够将它安装在我的设备上。但我仍然面临一个问题......应用程序安装在设备上，我得到了我已经在我的设备上的各种 pdf 的列表，我点击任何人，但它没有在查看器上渲染和显示，而是尝试渲染，然后我再次获得 pdf 列表，但没有查看我的 pdf。

没有想法，出了什么问题....

Answer 1

你是在模拟器上运行的吗..???如果是，则发布 logcat 输出...＆您是否使用 muPdf 制作了自己的应用程序，因为只有 muPdf 无法呈现 PDF..

看到这个应用程序，这些都是免费的..
