Drawable folders in res folder?

Question

What is the difference between the three drawable folders in the res folder in the project hierarchy? If I have an image to put into a folder, which folder do I put it in? <

Answer 1

Here is a reference to multi device options.

As said by @CommonsWare, you don't need to put resources in anything but res/ layout/ or drawable/ but if you want your program to have a better experience on multiple devices with different screens / density / languages you may want to consider that you have that option.
