OpenCV安卓库安装后出现错误

Question

我使用的是Win8、jdk7、Eclipse4.2、Andoird SDK (ADT) Rev 21、OpenCV 2.4.3、C/C++ Dev。工具8.1.1。安装的都是从API Level 8开始安装的Android Target SDK，详情请参见：http://docs.opencv.org/doc/tutorials/introduction/android_binary_package/O4A_SDK.html

导入库和示例项目后，我在文件OpenCVEngineInterface中收到以下错误。mac os也是如此。

Answer 1

具体地说，昨天晚上，我遇到了和你一样的问题，今天我找到了解决方案。显然，或者我们的Eclipse有一些默认配置，或者我们从OpenCV获得的Eclipse项目是错误的。

要解决此问题，请转到Eclipse下的项目，然后：

1. 鼠标右键button
2. Properties
3. Java Compiler
4. Compiler合规性级别= 1.6

我使用的是Java版本1.5，它在覆盖方法方面有一些问题，但在Java 1.6中，它工作得很好！我希望我已经帮到你了:D

编辑:我公开的解决方案比另一个更好。您不必更改您的ADT，只需更改Java编译器的版本，它将不会出现问题:D

Answer 2

看起来在不同版本的ADT插件之间的Eclipse项目设置中存在一些不兼容的地方。要消除这些错误，您必须在导出到Eclipse之前从/sdk/java文件夹中删除.settings文件夹。感谢: Andrey Pavlenko http://answers.opencv.org/question/4209/build-errors-after-opencv-library-import/

在这里发布了一个对我有效的解决方案...

在导入示例工程之前，移除OpenCV-2/sdk/java下的.settings文件夹。
