相关疑难解决方法(0)

只是想尝试一个简单的openCV android程序.按照此处的说明下载并安装OpenCV for Android ,并将OpenCV Library 2.4.2添加为我自己的android项目的库项目,如指令状态.

但是,当我编译标准的"Hello World Program"时,如下所示,如果我包含该Mat mat = new Mat();行,则会失败,否则会成功.

package com.example;

import org.opencv.core.Mat;

import android.app.Activity;
import android.os.Bundle;

public class HelloAndroidActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Mat mat = new Mat();
    }
}

这是打印出来的堆栈跟踪:
