Question

我试图在AIR项目上使用JavaCV。我构建了一个原生扩展，它编译得很好，但在运行时我收到以下错误：

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

看起来我没有正确链接图书馆资源，主题上的文档似乎非常有限。

将.jar和armeabi / _ .so库链接到ANE时有什么想法或问题吗？

升级到最新的javacv源后更新了错误日志：

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;

关联.so依赖关系：

您应确保文件夹结构正确无误。请参阅 Android原生库部分下的"This link"。只需将.so本机依赖项放在＆＃34; libs / target_platform /＆＃34;文件夹确保ADT将它们放在最终APK内的正确位置。

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

如果你支持多种架构，你可能也会有 YOUR_ANE_ROOT_FOLDER /机器人/库/的 armeabi /libYourLibrary.so

依旧......

还要确保您的共享对象以＆＃34; lib＆＃34;命名。字首。示例： libYourLibrary.so

关联JAR依赖关系：

如果在＆＃34; packagedDependencies＆＃34;下的platform.xml中指定JAR依赖项。标签不起作用，您可以尝试提取所有外部JAR并将它们包含在最终的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"/>
