Question

如何解决此问题？

我只是在我的项目Lib文件夹下复制javacv jar文件并出现此错误！

我可以从谷歌找到这个thread，但由于我国的谷歌限制政策，页面无法打开。

我在Android应用程序中包含这些jar的原因是我不想使用openCV manager。我想静态地将openCV库链接到我的项目。我正在尝试在Samsung Galaxy S5上运行我的应用。

以下是我遇到的LogCat错误：

修改-1 在我按照here中的说明操作后，感谢PRAKASH我可以解决这些错误，但我还有其他与NoClassDefFoundError完全相关的错误。我真的放弃了。我无法解决这个问题，所以任何帮助都会非常感激。以下是我的新错误：

Answer 1

下载Javacv latest version

并提取并放入项目的ffmpeg.jar文件夹中的javacv.jar，javacpp.jar，opencv.jar和libs

并从提取的

中提取所有* .so

opencv-android-arm.jar,ffmpeg-android-arm.jar files.

并将所有* .so文件放在 libs / armeabi 文件夹中

Answer 2

如果您还没有安装Android开发环境，可以点击此链接，其中包含快速入门所需的一切。观看教程视频并按照下面的说明安装Eclipse，用于Android开发的集成开发环境（IDE）并创建一个新项目。

安装完所有内容并创建项目后，使用以下过程将JavaCV库导入Android项目：

下载JavaCv库：一个。从此链接下载＆＃34; javacv-0.7-bin.zip ＆＃34;并提取文件： - javacpp.jar - javacv.jar - javacv-android-arm.jar 湾从此链接下载＆＃34; javacv-0.7-cppjars.zip＆＃34;并提取文件： - opencv-2.4.8-android-arm.jar - ffmpeg-2.1.1-android-arm.jar

转到文件＆gt;新＆gt;文件夹，选择您的项目作为父文件夹，键入＆＃34; libs / armeabi＆＃34;作为文件夹名称，然后单击“完成”。

将javacpp.jar和javacv.jar复制到＆＃34; libs＆＃34;文件夹中。

将所有* .so文件从javacv-android-arm.jar，opencv-2.4.8-android-arm.jar和ffmpeg-2.1.1-android-arm.jar直接提取到＆＃34;库/ armeabi＆＃34;文件夹，不创建在JAR文件中找到的任何子目录。（从.jar中提取.so文件的最简单方法是使用7-ZIP软件，可以在这里下载）。

导航至项目＆gt;属性＆gt; Java构建路径＆gt;图书馆并点击＆＃34;添加JAR ...＆＃34;。

从＆＃34; libs＆＃34;中选择javacpp.jar和javacv.jar。文件夹中。

最后，将JavaCV函数导入代码

 import static com.googlecode.javacv.cpp.opencv_core.*;
 import static com.googlecode.javacv.cpp.opencv_imgproc.*;
 import static com.googlecode.javacv.cpp.opencv_highgui.*;

并使用一些示例代码检查一切是否正常。
