我在Android项目中使用JavaCV来操纵一些图像。 我使用JavaCV的本地库成功创建了纯Java项目，该应用程序正常工作。 后来我想尝试端口项目常规的Android：Groovy for Android与JavaCV导致NoClassDefFoundError
- 我跟着这里的指示进行操作：https://speakerdeck.com/glaforge/groovy-on-android-droidcon-paris-2014
- 我更换了所有的.java文件的扩展到.groovy作为。 项目构建并运行良好（耶！）到到Javacv库的本地电话，然后我得到这个讨厌的例外：

下面是一个使用Javacv代码片段：
FFmpegFrameRecorder recorder = new FFmpegFrameRecorder(outFile, width, height);
recorder.setVideoCodec(avcodec.AV_CODEC_ID_MPEG4);
recorder.setFormat("mp4");
recorder.setFrameRate(frameRate);
recorder.setVideoQuality(videoQuality);
/* some non Javacv stuff */
while(!finished)
{
opencv_core.IplImage image = cvLoadImage(picPath);
recorder.record(image);
opencv_core.cvReleaseImage(image);
}
我知道Android没有与AWT一起发布，但就简单的Java项目而言，这不是问题。我只有在使用Groovy时才遇到这个问题。我只是花了整整一个早上试图弄清楚这一点，没有运气，也尝试通过产生的调试apk通过Proguard，但它只是使更多的困惑。 任何想法如何解决这个问题？
