Question

当我使用＆＃39; javah＆＃39;生成带有JNI的头文件时它显示

Error: Class org.opencv.core.Mat could not be found.

系统：Mac OSX

使用：Android Studio和opencv 3.1 for android

命令行：

javah -classpath /Users/lumeng/Library/Android/sdk/platforms/android-23/android.jar:. com.lumenghz.test.OpencvHelper

谁能帮帮我？

修改-1 我也试过

javah -d ~/Documents/androidworkspace/RumenTest/test/src/main/jni -classpath /Users/lumeng/Library/Android/sdk/platforms/android-23/android.jar:. com.lumenghz.test.OpencvHelper

但仍然有同样的错误：

Error: Class org.opencv.core.Mat could not be found.

Answer 1

你在这里提供了错误的课程路径：

com.lumenghz.test.OpencvHelper

像这样给出完整的类路径：

〜/文档/ androidworkspace / RumenTest / openCVLibrary310 /建造/中间体/类/调试:. com.lumenghz.test.OpencvHelper

  javah -d (JNI Folder Location) -classpath (JAR Locaion);(class Path)

根据您的路径示例 -

 javah -d ~/Documents/androidworkspace/RumenTest/test/src/main/jni -classpath /Users/lumeng/Library/Android/sdk/platforms/android-23/android.jar;~/Documents/androidworkspace/RumenTest/openCVLibrary310/build/intermediates/classes/debug: com.lumenghz.test.OpencvHelper

Answer 2

<强>解决

我应该声明已经构建的opencv-sdk-android的类路径。

所以commandLine应该是这样的：

javah -classpath ~/Documents/androidworkspace/RumenTest/openCVLibrary310/build/intermediates/classes/debug:. com.lumenghz.test.OpencvHelper

错误：找不到类org.opencv.core.Mat
