[solved]How do I configure Qt 5.3 for Android opencv 2.4.9 ? (on mac os x)

ismail_gz

I corrected some errors. Now deploying project but did not work application.
This is my application output:

There's something that puzzles me, why do you have

@CONFIG+=link_pkgconfig PKGCONFIG+=opencv@

since you already link to the static libraries ?

ismail_gz

You're right but I already deleted that line. Despite this occurred error.

SGaist

Did you do a full rebuild ?

ismail_gz

Yes, I did

SGaist

Re-reading your error, it seems you are using a method that is not implement for android. Can you share the OpenCV code you are using ?

ismail_gz

it's a simple code:

@#include "opencv2/opencv.hpp"
#include "opencv2/highgui/highgui.hpp"

using namespace cv;

int main(int argc, char *argv[])
{
namedWindow("output",1);
Mat output = Mat::zeros(120,350,CV_8UC3);
putText(output,"Hello world :)", cvPoint(15,70), FONT_HERSHEY_PLAIN,3,cvScalar(0,255,0),4);
imshow("Output",output);
waitKey(0);
return 0;
}@

SGaist

Wild guess but I'd say that either namedWindow, imshow or both are not implemented for android

ismail_gz

Could you recommend a sample code.

SGaist

Not really, since you are currently using OpenCV only code, you should rather ask on the OpenCV forum for their support on android

johnthesoftware

Did you resolve this? I'm about to try the same thing on Fedora.

No, I couldn't yet. My main problem is sample code at the moment. I couldn't find sample code about this subject. But I found configurations from this "link":http://stackoverflow.com/questions/27562311/how-to-integrate-opencv-into-qt-creator-android-project
I hope that helps.

Finally, I found it. Configurations are my previous reply. And you must copy libnative_camera_r4.2.0.so(must be compatible with the your android version(this is important)) to project_root/android/libs/armeabi-v7a/ .
Then you can watch "this":https://www.youtube.com/watch?v=0ONxIy8itRA video for source code.

This is already solved but anyway here is how I do it all the time:
