Answer 1

Just open an input stream for the file. As if you were going to read the file.

If you manage to open it the file does exist. Otherwise you get an exception.

Answer 2

use below method to get file from assets folder. i provide code get all .mp4 file and store file into string list.

private List<String> videoList=new ArrayList<>();
  private boolean listAssetFiles(String path) {

    String [] list;
    try {
        list = getAssets().list(path);
        if (list.length > 0) {
            // This is a folder
            for (String file : list) {
                if (!listAssetFiles(path + "/" + file))
                    return false;
                else {
                    // This is a file
                    // TODO: add file name to an array list
                    if (file.contains(".mp4") || file.contains(".mp3") ) {
                        videoList.add(file);
                    }
                }
            }
        }
    } catch (IOException e) {
        return false;
    }

    return true;
}

when you call this method pass only ..

    listAssetFiles(""); // you can pass your path if is empty then it scan root.
