Question

我已经缩减了15-puzzle的代码，这是opencv4android的一个例子。现在，短端代码在其原始文档位置运行良好，但在我将它们复制到其他地方设置的helloworld项目之后，程序与Logcat崩溃，并发布了MainActivity的NoClassFoundDefError。我试图查看manifest.xml但仍然无法找出问题的原因。你能帮助我吗？谢谢！

以下是我的代码：

1.puzzle15Activity

package org.opencv.samples.puzzle15;
import org.opencv.android.BaseLoaderCallback;
import org.opencv.android.LoaderCallbackInterface;
import org.opencv.android.OpenCVLoader;
import org.opencv.core.Mat;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;
import android.view.Window;
import android.text.method.*;
import android.widget.Toast;
import android.view.View;
import android.view.*;


public class puzzle15Activity extends Activity
{

SampleCvViewBase mView=null;
private BaseLoaderCallback  mOpenCVCallBack = new BaseLoaderCallback(this) 
{
    @Override
    public void onManagerConnected(int status) {
        switch (status) {
            case LoaderCallbackInterface.SUCCESS:
            {
                mView=new SampleCvViewBase(mAppContext);
                setContentView(mView);


            } break;
            default:
            {
                super.onManagerConnected(status);
            } break;
        }

    }
};


@Override
public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_2_4_2,this,mOpenCVCallBack);

}

}

2.SampleCvViewBase

package org.opencv.samples.puzzle15;

import java.util.List;
import org.opencv.core.Mat;
import org.opencv.core.Size;
import org.opencv.highgui.VideoCapture;
import org.opencv.highgui.Highgui;
import org.opencv.core.Scalar;
import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.Canvas;
import android.util.Log;
import android.view.SurfaceHolder;
import android.view.SurfaceView;
import org.opencv.core.*;
import org.opencv.calib3d.Calib3d;

class SampleCvViewBase extends SurfaceView implements SurfaceHolder.Callback, Runnable {


int t;
Scalar s=new Scalar(100,100,100,100);
Scalar s1=new Scalar(1);
Scalar s2=new Scalar(100);
byte []t1={1,0,0,1};
int []t2={5,4,3,2};
int[] t3;



Mat mrgba;
Mat m1,m2,m3;
public int[] list={1,2,3};

@Override
public SampleCvViewBase(Context context) {
    super(context);
    mrgba=new Mat(4,4,CvType.CV_16S,s);
    mrgba.create(4,4,CvType.CV_8UC(15));
    m1=new Mat(2,2,CvType.CV_8U,s1);
    m2=new Mat(2,2,CvType.CV_32S,s2);
    m3=new Mat(2,2,CvType.CV_32S,s2);
    m1.put(0,0,t1);
    m2.put(0,0,t2);
    t3=new int[4];
    m2.get(0,0,t3);
    t3[1]=200;
    m2.put(0,0,t3);
    m2.copyTo(m3);


}

public void surfaceChanged(SurfaceHolder _holder, int format, int width, int height) {

}

public void surfaceCreated(SurfaceHolder holder) {

      }

public void surfaceDestroyed(SurfaceHolder holder) {

    }

public void run() {}

}

Answer 1

好的，现在我发现了一些背后的原因。 bin中的类未编译。
