FileNotFoundException при открытии файла из assets

Почему появляется эта ошибка, если файл существует?

AssetManager am = getApplicationContext().getAssets();
String[] files = am.list("my_images");
ArrayList<Drawable> drawables = new ArrayList<>();
for (String file : files) {
    showLog(file);
    Drawable d = Drawable.createFromStream(am.open(file), null);
    drawables.add(d);
}
