我是 android 新手。我想在 android 中使用 tesseract-ocr 应用名片扫描仪。我搜索了很多与这些项目相关的东西。基于我使用了这些模块：

 1) eclipse sdk 
 2) eclipse ndk
 3) cygwin
 4) android-emulator
 5) windows-xp (os)

现在主要问题是：我不知道如何在 ndk 和 cygwin 的帮助下运行 tesseract-ocr 代码。我已经下载了以下给定的文件。有人可以让我知道这些文件是否对我有帮助。

 1) tesseract-3.00.tar.gz  (Link :- http://code.google.com/p/tesseract-ocr/downloads/detail?name=tesseract-3.00.tar.gz)
 2) tesseract-android-tools-1.00.tar.gz  (Link :- http://code.google.com/p/tesseract-android-tools/downloads/detail?name=tesseract-android-tools-1.00.tar.gz)

非常感谢，任何关于任何特定解决方案的知识都非常受欢迎！:)

只需下载 tesseract 2.03，以下是 android.mk 文件，使用 android ndk 编译它对我来说效果很好。
