使用 Emgu CV（libemgucv-android-2.4.2.1773-RC）运行Monodroid应用程序（Xamarin试用版），当它尝试加载 libopencv_highgui时会抛出UnsatisfiedLinkError。所以，以回应下面的代码行。其他Emgu电话似乎工作正常。

var camera = new Capture();
  1. 在调试或发布模式下运行（Visual Studio 2010）具有相同的错误。
  2. 我的解决方案和APK包含模拟CPU / ABI的所有正确的SO文件（包括libopencv_highgui.so）。
  3. 我尝试了各种API级别，但都有相同的错误。
  4. “adb logcat”似乎与下面的VS异常堆栈没有任何不同。

    5. 下面是异常堆栈。

答案 0 :(得分：0)

事实证明我有32位JDK＆amp;安装了64位JDK。一旦我卸载了32位，我就克服了这个错误。然后我开始获得initcameraconnect: Unable to connect to CameraService。但是我通过将Android权限添加到Android Manifest（应用程序属性＆gt; android清单＆gt;创建xml文件＆gt;权限）来解决这个问题。
