库'javacv-android-arm.jar‘包含无法在设备上运行的本地库。

Question

我怎样才能解决这个问题？

我只是在我的项目Lib文件夹下复制了javacv文件，并得到了这个错误！

我可以从谷歌找到这个线程，但由于谷歌在我国的限制政策，页面无法打开。

我将这些jars包含在我的android应用程序中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。我正试图在Samsung Galaxy S5上运行我的应用程序。

下面是我得到的LogCat错误：

编辑-1后，我按照这里的指示，感谢普拉卡什，我可以解决这些错误，但我有其他错误，完全相关的NoClassDefFoundError。我真的放弃了。我不能解决这个问题，所以任何帮助都是非常感谢的。以下是我的新错误：

Answer 1

下载Javacv最新版本

并将其解压缩并将ffmpeg.jar、javacv.jar、javacpp.jar和opencv.jar放在项目的libs文件夹中。

同时提取提取的所有*.so。

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

并将所有*.so文件放入库/armeabi文件夹中。

它可以解决你的问题。

Answer 2

如果您还没有安装，您可以遵循这个链接，它包含了快速入门所需的所有内容。观看教程视频，并按照下面的说明安装Eclipse，这是用于Android开发的集成开发环境(IDE)，并创建了一个新项目。

一旦安装了所有内容并创建了该项目，请使用以下过程将JavaCV库导入到Android项目：

下载JavaCv库: a.从该链接下载"javacv-0.7-bin.zip“并解压缩文件：- javacpp.jar - javacv.jar - javacv-android-arm.jar b。从该链接下载"javacv-0.7-cppjars.zip”并解压缩文件：- opencv-2.4.8-android-arm.jar -ffmpeg-2.1.1-androd-arm.jar

转到File > New >文件夹，选择您的项目作为父文件夹，键入"libs/armeabi“作为文件夹名，然后单击Finish。

将javacpp.jar和javacv.jar复制到"libs“文件夹中。

将javacv-Androd-arm.jar、opencv-2.4.8-Androd-arm.jar和ffmpeg-2.1.1-Androd-arm.jar中的所有*.so文件直接提取到"libs/armeabi“文件夹中，而无需创建JAR文件中的任何子目录。(从.so中提取.jar文件的最简单方法是使用7-ZIP软件，该软件可以在这里下载)。

导航到Project > Properties > Java构建路径>库，然后单击"Add .“。

从"libs“文件夹中选择javacpp.jar和javacv.jar。

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来检查一切是否正常。
