的Android 3.0 OpenCV的问题

我有2.4.10的Android 3.0 OpenCV的问题

package org.opencv.samples.tutorial1; 

import java.util.List;

import org.opencv.android.CameraBridgeViewBase.CvCameraViewListener2; 

import android.app.Activity; 
import android.os.Bundle; 
import android.util.Log; 
import android.view.Menu; 
import android.view.MenuItem; 
import android.view.SurfaceView; 
import android.view.WindowManager; 
import android.widget.Toast; 

public class Tutorial1Activity extends Activity implements CvCameraViewListener2 { 
    private static final String TAG = "OCVSample::Activity"; 
private CameraBridgeViewBase mOpenCvCameraView; 
private boolean    mIsJavaCamera = true; 
private MenuItem    mItemSwitchCamera = null; 
Mat gray = new Mat(); 
Mat cany = new Mat(); 


//private List<MatOfPoint> contours; 

private BaseLoaderCallback mLoaderCallback = new BaseLoaderCallback(this) { 
    @Override 
    public void onManagerConnected(int status) { 
     switch (status) { 
      case LoaderCallbackInterface.SUCCESS: 
      { 
       Log.i(TAG, "OpenCV loaded successfully"); 
       mOpenCvCameraView.enableView(); 
      } break; 
      default: 
      { 
       super.onManagerConnected(status); 
      } break; 
     } 
    } 
}; 

public Tutorial1Activity() { 
    Log.i(TAG, "Instantiated new " + this.getClass()); 
} 

/** Called when the activity is first created. */ 
@Override

    Log.i(TAG, "called onCreate"); 
    super.onCreate(savedInstanceState); 
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON); 

    setContentView(R.layout.tutorial1_surface_view); 

    mOpenCvCameraView = (CameraBridgeViewBase) findViewById(R.id.tutorial1_activity_java_surface_view); 

    mOpenCvCameraView.setVisibility(SurfaceView.VISIBLE); 

    mOpenCvCameraView.setCvCameraViewListener(this); 
} 

@Override 
public void onPause() 
{ 
    super.onPause(); 
    if (mOpenCvCameraView != null) 
     mOpenCvCameraView.disableView(); 
} 

@Override 
public void onResume() 
{ 
    super.onResume(); 
    if (!OpenCVLoader.initDebug()) { 
     Log.d(TAG, "Internal OpenCV library not found. Using OpenCV Manager for initialization"); 
     OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_3_0_0, this, mLoaderCallback); 
    } else { 
     Log.d(TAG, "OpenCV library found inside package. Using it!"); 
     mLoaderCallback.onManagerConnected(LoaderCallbackInterface.SUCCESS); 
    } 
} 

public void onDestroy() { 
    super.onDestroy(); 
    if (mOpenCvCameraView != null) 
     mOpenCvCameraView.disableView(); 
} 

public void onCameraViewStarted(int width, int height) { 



} 

public void onCameraViewStopped() { 
} 

public Mat onCameraFrame(CvCameraViewFrame inputFrame) { 



    gray = inputFrame.gray(); 

    Imgproc.Canny(gray, cany, 225, 250, 3, true); 









    return cany; 




    } 
}

当我OpenCV库更改为3.0的STOPP工作这段代码的工作非常出色的OpenCV的公司给我不幸的是，项目名称预览已停止

和亚洲开发银行错误的

其在3.0的工作，如果我这样做

gray = inputFrame.gray(); 

    Imgproc.Canny(gray, cany, 225, 250, 3, true); 

    return cany;

将其更改为

gray = inputFrame.gray(); 

    return gray;

任何帮助

只是使输入垫和输出大小和类型，当相机启动这样

public void onCameraViewStarted(int width, int height) { 
cany= new Mat(height, width, CvType.CV_8UC4); 
} 

public void onCameraViewStopped() { 
    cany.release(); 
}

// OnCameraFrame

Imgproc.Canny(inputFrame.gray(), cany, 220, 250); 
    return cany;
