Hi everyone,
I want to develop Opencv for Android in Qt 5.3 but I don't know how do it.
I try configure .pro file but did not work.

Please help me..

Hi and welcome to devnet,

What exactly did not work ? Did you get an OpenCV version prebuilt for Android ?

Thanks,
I downloaded opencv here: "Opencv Android":http://sourceforge.net/projects/opencvlibrary/files/opencv-android/2.4.9/OpenCV-2.4.9-android-sdk.zip/download
then I extract to /home/ismail/

AFAIK, you can't currently run an application that doesn't link to the QtGui library since you need the platform plugin to start your application

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

@CONFIG+=link_pkgconfig PKGCONFIG+=opencv@

since you already link to the static libraries ?

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

SGaist · wrote on 9 Sept 2014, 22:31

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 · wrote on 10 Sept 2014, 13:59

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 · wrote on 10 Sept 2014, 20:10

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

ismail_gz · wrote on 11 Sept 2014, 12:16

Could you recommend a sample code.

SGaist · wrote on 11 Sept 2014, 21:01

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

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.
