在 Eclipse 中导入 openCV 时出现的错误不会消失吗？

Question

我正在使用本指南：

http://opencv.itseez.com/ doc/tutorials/introduction/android_binary_package/android_binary_package.html

在我导入openCV之后，eclipse列出了一堆错误，这是预期的 指导。

但该指南表示，在按 F5 或从菜单中选择“修复项目属性”后，这些错误应该会消失。我都尝试过。我的错误不会消失。我做错了什么？

好吧，看来我之前的回答不太好，这次我知道问题出在哪里了。

正如您所指出的，您应该遵循教程中的每个步骤。棘手的部分是你应该下载这个 OpenCV 包“OpenCV-2.3.1-android-bin.tar.bz2" 而不是这个 "http://sourceforge.net/projects/opencvlibrary/files/opencv-android/ ” （在那里标记为“”寻找最新版本？下载 OpenCV-2.3.1a.tar.bz2 (32.7 MB)

） OpenCV-2.3.1-android-bin.tar.bz2 包按照教程所述进行（解压缩包，复制到所需位置，将其导入到 Eclipse 等），我什至没有收到教程中提到的错误。

我使用的是 Mac Lion、Eclipse Indigo Release 2 和 Android SDK 2.3.3，这些示例在 Samsung Galaxy S II 手机中运行顺利。
