【问题标题】：Errors importing openCV in Eclipse wont go away?在 Eclipse 中导入 openCV 的错误不会消失？

我正在使用本指南：

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

我导入openCV后，eclipse列出了一堆错误，这是指南预料到的。

但是指南说这些错误应该在按 F5 或从菜单中选择“修复项目属性”后消失。我都试过了。我的错误不会消失。我究竟做错了什么？

来自 Eclipse：

【解决方案1】：

好吧，看来我之前的答案不是很好，这次我弄清楚了问题所在。

正如您所指出的，您应该按照教程中的每个步骤进行操作。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“”正在寻找最新版本？下载 OpenCV-2.3.1a.tar.bz2 (32.7兆））

那些你下载 OpenCV-2.3.1-android-bin.tar.bz2 包的人按照教程所说的进行（解压缩包，复制到所需位置，将其导入 Eclipse 等），我什至没有得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，示例在三星 Galaxy S II 手机中运行流畅。
