我正试图在一个航空项目中使用JavaCV。我构建了一个本机扩展，它编译得很好，但是在运行时我得到了以下错误：

W/dalvikvm(16234): VFY: unable to find class referenced in signature (Ljava/awt/image/BufferedImage;)
W/dalvikvm(16234): VFY: unable to find class referenced in signature (Ljava/awt/image/BufferedImage;)

D/dalvikvm(16234): GC_CONCURRENT freed 612K, 7% free 9380K/10028K, paused 3ms+4ms, total 35ms

看来我没有正确地链接库资源，而有关这些主题的文档看起来非常有限。

当将.jar和armeabi/_.库链接到ANE时，有什么想法或理解吗？

升级到最新的javacv源后更新的错误日志：

W/dalvikvm(14799): Exception Ljava/lang/UnsatisfiedLinkError; thrown while initializing Lorg/bytedeco/javacpp/avutil;
W/dalvikvm(14799): Exception Ljava/lang/NoClassDefFoundError; thrown while initializing Lorg/bytedeco/javacpp/avformat;
W/dalvikvm(14799): Exception Ljava/lang/UnsatisfiedLinkError; thrown while initializing Lorg/bytedeco/javacpp/opencv_core;

链接.so依赖项：

您应该确保您的文件夹结构正确。参见“这个链接”下的Android本机库部分。只需在“libs/ .so _platform/”文件夹中放置您的本机依赖项，就可以确保ADT将它们放在最终APK中的正确位置。

示例：YOUR_ANE_ROOT_FOLDER/android/libs/armeabi-v7a/libYourLibrary.so

如果您支持多个体系结构，那么您也可能有一个YOUR_ANE_ROOT_FOLDER/android/libs/armeabi/libYourLibrary.so

以此类推。

还要确保您的共享对象使用"lib“前缀命名。示例：libYourLibrary.so

链接JAR依赖项：

如果在platform.xml中"packagedDependencies“标记下指定jar依赖项不起作用，则可以尝试提取所有外部JAR并将它们包含在最后的jar中。

示例：

        <javac source="1.6" srcdir="../android/src" destdir="../android/temp/classes" includeantruntime="false">
        <classpath>
          <pathelement location="${android.sdk}/android.jar"/>
          <pathelement location="../android/libs/FlashRuntimeExtensions.jar"/>
          <pathelement location="../android/libs/android-support-v4.jar"/>
          <pathelement location="../android/libs/opencv.jar"/>
          ....
          ....
        </classpath>
      </javac>

      <mkdir dir="../android/temp/zip"/>
      <unzip src="../android/libs/opencv.jar" dest="../android/temp/zip"/>
      <unzip src="../android/libs/android-support-v4.jar" dest="../android/temp/zip"/>
      ...
      ...

      <copydir src="../android/temp/zip/com" dest="../android/temp/classes/com"/>
      <copydir src="../android/temp/zip/android" dest="../android/temp/classes/android"/>

      <mkdir dir="../temp/android/"/>
      <copy todir="../temp/android/res/">
        <fileset dir="../android/res"/>
      </copy>
      <jar destfile="../temp/android/lib${name}.jar">
        <fileset dir="../android/temp/classes"/>
      </jar>
      <delete dir="../android/temp"/>
