Please give me some suggestion

import static com.googlecode.javacv.cpp.opencv_highgui.*;


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);
        try {



            try {
                cvLoadImage("mnt/sdcard/make_machine_example1.png");
            } catch (Exception e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

        } catch (Exception e) {
            e.printStackTrace();

Do you have any idea about it ? Thanks

回答1:

I have answered your question here. You maybe need to add the .so files in the armeabi folder too, not only armeabi-v7a. I had that problem but in the opposite way and I solved doing it.

By the way, how do you use the function? Remember that you have to put the whole name (also with the directories) if you are not working with pictures in the same folder. I would put it just in case even in that case.

I do it like this and it works:

cvLoadImage("/storage/sdcard0/Download/testpicture.JPG");

回答2:

Just put all the *.so files DIRECTLY inside your projects libs/armeabi directory. DO NOT put them inside any other sub-directories such as: libs/armeabi/com/googlecode/... etc
