How do I get a list of images in a specific folder on Android?

You can use below code to get all images from specific folder. 1) First you need to define File object to get the storage and appened the name of the folder you want to read. File folder = new File(Environment. getExternalStorageDirectory().

you can use glob to get a list of filenames:

vector<cv::String> fn;
glob("/home/images/*.png", fn, false);

vector<Mat> images;
size_t count = fn.size(); //number of png files in images folder
for (size_t i=0; i<count; i++)
    images.push_back(imread(fn[i]));
