Question

I would like to list files contained into assets subdirectory called “subDir” and am using following code. However, if I set dirFrom = “” (empty), lists all folders in assets properly. However, for dirFrom = “/subDir/”, doesn’t work. I already tried “subDir/” and same result. Is necessary to declare permissions in manifest? Thank you.

private void copyFiles(String dirFrom, String dirTo) throws IOException {

    AssetManager am = getAssets();

    String fileList[] = am.list(dirFrom);

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

}

AssetManager.list(String) takes a “relative path within the assets”.

Android / Java usually expects paths to have no '/' in the end.

Also “relative” means that there should be no '/' at the start – it could otherwise be a path in the root of your filesystem.

Using just "subDir" or "subDir/subsubDir" will work.
