How to accès images from drawable folder?

Im trying to create gallery application. In tutorial I've found, I need to do get images using R.drawable.image_name. I've created folder drawable under /res folder, copied my images one by one into that folder, al of them are .png. But when I try to access them by writing R.drawable.image I can't do that because there is no images I've copied. How to fix it?

Do clean build or if you are using android studio do invalidate cache and make project afterwards.

For Accessing Drawable:

Drawable drawable = this.getResources().getDrawable(R.drawable.image_name);

If you want bitmap :

Bitmap bitmap = BitmapFactory.decodeResource(context.getResources(), R.drawable.image_name);

if you want to access by url : 

imgUrl= "drawable://" + R.drawable.image_name;

Clear and rebuild your project. If you got automatic builds disabled, your IDE will not refresh R class contents and won't autocomplete your assets IDs.
