我已經下載了OpenCV項目的android和與它捆綁在一起的示例項目包含幾個錯誤.... 只有包含NDK代碼的項目有錯誤.... 問題是,C++代碼展示了許多錯誤...... 喜歡的jstring關鍵字不認可.. 請幫我解決這個問題... 請多關照您的寶貴時間OpenCV for android示例程序顯示錯誤
#include <jni.h>
#include <opencv2/core/core.hpp>
#include <opencv2/imgproc/imgproc.hpp>
#include <opencv2/features2d/features2d.hpp>
#include <vector>
using namespace std;
using namespace cv;

Mat mgray(height, width, CV_8UC1, (unsigned char *)_yuv);
//Please make attention about BGRA byte order

您應該發佈錯誤消息和它們對應的代碼。 – Michael 2012-07-27 08:45:10

您使用的是Eclipse嗎?如果是這樣,你有沒有試過這個:http://stackoverflow.com/questions/9375708/eclipse-indexer-errors-when-using-stl-with-android-ndk? – Michael 2012-07-27 09:08:50
