如何在Android上安装JavaCV并使用FrameGrabber

>从Android开发者网站下载了adt-bundle-windows
>创建了一个新项目和一个libs / armeabi文件夹
>将所有* .so文件从javacv-android-arm.jar,opencv-2.4.3-android-arm.zip和ffmpeg-1.0-android-arm.zip直接提取到新创建的“libs / armeabi”文件夹中,不创建任何新的子目录.

(我不明白的一部分是“从javacv-android-arm.jar中提取所有* .so文件”,我只是在libs / armeabi文件夹中插入了javacv-android-arm.jar文件)
>导航到项目>属性> Java构建路径>库,然后单击“添加JAR …”.
>从新创建的“libs”文件夹中选择javacpp.jar和javacv.jar.

之后我从here下载了OpenCV2.4.3,从here下载了ffmpeg,并在我的C：/ root上提取了文件.
最后在设置我的系统路径后…,

C:\opencv\build\x64\vc10\bin;C:\ffmpeg-64\bin;C:\Program Files\Java\jdk1.7.0_10\bin

…如果我尝试在我的Android应用程序中使用简单的FrameGrabber …

import com.googlecode.javacv.FFmpegFrameGrabber;
import com.googlecode.javacpp.Loader;
import com.googlecode.javacv.*;
import com.googlecode.javacv.cpp.*;
import static com.googlecode.javacv.cpp.opencv_core.*;
import static com.googlecode.javacv.cpp.opencv_imgproc.*;
import static com.googlecode.javacv.cpp.opencv_calib3d.*;
import static com.googlecode.javacv.cpp.opencv_objdetect.*;

import android.os.bundle;
import android.app.Activity;
import android.view.Menu;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceStatE) {
        super.onCreate(savedInstanceStatE);
        setContentView(R.layout.activity_main);

        FFmpegFrameGrabber i = new FFmpegFrameGrabber("/mnt/sdcard/SinglePerson.avi"); 
    }

…我收到以下错误：

有人可以帮帮我吗？
