JavaCV在安卓上出现ExceptionInInitializerError异常

JavaCV在安卓上出现ExceptionInInitializerError异常

androidopencvjavacvcomputer-vision

3

我正在尝试在Android项目中运行JavaCV代码。当我在Windows 7上运行时（使用Eclipse），此代码对我有效。

我搜索了我遇到的错误，并尝试根据论坛答案和其他描述设置了一切，但仍然没有运气。

我创建了一个libs文件夹，并将*.Jar文件包含在我的构建路径中。我还将*.so文件添加到libs \ armeabi文件夹中。

我会感激您在此事上及时回复。

以下是所有具体详情。 libs文件夹：

 <DIR>        .

Eclipse Android 插件的实际效果并不是很好。Android 本身的缓存机制也存在一些 bug，因此尝试卸载所有内容并从头开始重新创建所有项目文件。这样能解决你的问题吗？ - Samuel Audet

检查你的res文件夹。尝试从你拥有的opencv代码示例中复制所有内容。似乎无法加载图像。或者，你可以清理你的项目（在菜单中选择Project>Clean），或者使用真实的手机而不是模拟器。看看是否有任何选项可以解决你的错误。
