title: Should I use /res/drawable or I have to store images in my internal storage?
body: <p>I'm making an app that shows images in a ImageView. </p>
  
  <p>I have the images that I want to show and them won't change in runtime but there a lot of them (400+/-). And I don't know if I can use directly from the folder /res/drawable or if I have to store them in the internal storage. </p>
  
  <p>Do you have any suggestion? </p>
