编译droidreader PDF阅读器

DroidReader 是 Android 手机平台下的 开源PDF 文档阅读软件。使用Mupdf为解析核心。

下载源码编译的时候，出了些小问题，顺便记录一下。

源码地址主页：http://code.google.com/p/droidreader/

主文件夹下有一个Readme文件，一定要看一下，这样才知道怎么去编译，需要哪些包，下面是截取Readme里最重要的一段

Optionally, you might want to use Eclipse and the Android plugin
for development. The sources are structured to easily have them
imported as a new project.

When you have done this, do the following:

- copy or symlink the libjpeg sources to the

  jni/jpeg/

  folder.
  Within that folder, make a copy of "jconfig.txt" with the
  name "jconfig.h". The NDK-based build run will otherwise
  complain on the missing "jconfig.h".

- copy or symlink the freetype2 sources into the

  jni/freetype/

  folder.

- copy or symlink the jbig2dec sources into the

  jni/jbig2dec/

  folder.

- copy or symlink the openjpeg sources into the

  jni/openjpeg/

  folder.
//连mupdf整个文件夹一起拷贝过来
- copy or symlink the MuPDF sources into the

  jni/mupdf/

  folder.

//把NDK设位环境变量
- make a symlink to the project root directory (containing
  this file) into the Android NDK's

  app/

  folder.

Your project tree is now ready.

仅是这样还是不行，还需要将ftiz和draw文件夹一起拷贝过来，这样就可以编译成功了，原因看一下jni目录下的Android.mk文件就知道了

导入到eclipse就可以编译运行了，顺便说以下，要想打开pdf文件，还需要像OI filemanager这样的文件管理器才可以。
