Question

So i have a folder at “mnt/sdcard/folder” and its filled with image files. I want to be able to scan the folder and for each of the files that is in the folder put each file path in an arraylist. Is there an easy way to do this?

Answer 1

You could use

List<String> paths = new ArrayList<String>();
File directory = new File("/mnt/sdcard/folder");

File[] files = directory.listFiles();

for (int i = 0; i < files.length; ++i) {
    paths.add(files[i].getAbsolutePath());
}

See listFiles() variants in File (one empty, one FileFilter and one FilenameFilter).
