I'm working on a face-recognition application on Android using JavaCV. I'm currently having issues accessing a facedata.xml file which will contain the data from the trained images. This is my code:
CvFileStorage fileStorage;
fileStorage = cvOpenFileStorage("/sdcard/external_sd/facedata.xml", null, CV_STORAGE_WRITE, null);
cvOpenFileStorage returns null
I'm not sure if it is an issue with JavaCV or what i'm doing wrong. It should be pretty straight forward.
