如何在Android中仅包含必要的OpenCV库？

概述我在 Android应用程序中通过JNI使用OpenCV. libopencv_java.so太大了,大约7M.显然,我只需要几个库. 我检查OpenCV4Android中的libs,找出一些静态库,比如libopencv_core.a 这是我在Android.mk中的新代码,包含必要的OpenCV库.我包括libopencv_core.a,libopencv_highgui.a,libopenc 我在 Android应用程序中通过JNI使用OpenCV.

这是我在AndroID.mk中的新代码,包含必要的OpenCV库.我包括libopencv_core.a,libopencv_highgui.a,libopencv_imgproc.a和一些第三方库,它们是：liblibjasper.a,liblibjpeg.a,liblibpng.a,liblibtiff.a

但它没有经过编译.一个长错误列表,所有与断言相关的失败：

我也试图改变这些静态库的顺序;但它不起作用.
有什么建议吗？

解决方法 静态库链接只会引入您在代码中实际使用的功能,而不是像.so一样引入整个库. 查看OpenCV AndroID示例项目,了解如何使用静态链接. 总结
