android - Android 上的 JavaCV 示例(FacePreview)无法正常工作

Question

我按照 http://code.google.com/p/javacv/ 中的指示做了所有事情(JavaCV 主页)。我的代码中没有错误。但是当我尝试在 android 模拟器上启动应用程序时，它说“不幸的是，appname 已经停止。我现在不知道去哪里看。有什么建议吗？

这些可以在 logcat 文本文件中找到。

尝试将其插入到 build.gradle 依赖项中

compile ‘org.bytedeco:javacv:+’
compile group: ‘org.bytedeco.javacpp-presets’, name: ‘opencv’, version:   ‘2.4.10–0.10', classifier: ‘android-arm’ 
compile group: ‘org.bytedeco.javacpp-presets’, name: ‘ffmpeg’, version:   ‘2.5.1–0.10', classifier: ‘android-arm’
