android list files contained in assets subfolder

Question

I create some folders into assets. Each folder contains files that I would like to list. I am using following code but I always get a null value for fileList. Thank you.

Answer 1

Simplest would surely be this:

String[] fileList = getAssets().list("images");

Answer 2

You'll probably want to do this:

private void listFiles(String dirFrom) {
        Resources res = getResources(); //if you are in an activity
        AssetManager am = res.getAssets();
        String fileList[] = am.list(dirFrom);

            if (fileList != null)
            {   
                for ( int i = 0;i<fileList.length;i++)
                {
                    Log.d("",fileList[i]); 
                }
            }
    }

Also your function call should be: listFiles("images"); if you want to list images.
