我正在尝试在Android上使用OpenCV
我创建了我的android项目，将javacv.jar和iavacpp.jar添加到构建路径，创建了lib文件夹并将*.so文件从javacv-arm.jar复制到libs/armeabi。
所有jar＆amp; *.so个文件是版本2.4.2。
当我运行应用程序时，我创建了一个测试按钮。单击它时，我正在调用此行：
IplImage image = cvLoadImage("file:///android_asset//"+"pic1.jpg");
并获得以下崩溃

我错过了libopencv_core.so吗？如果是这样，我在哪里可以找到它为2.4.2版本构建的？
谢谢！
答案 0 :(得分：1)
我相信你现在已经明白了。下载javacv-0.5-cppjars.zip，里面提取opencv-2.4.5-android-arm.jar的内容。你会在那里找到libopencv_core.so和其他几个.so文件
