title: How do I change the size of icons in Android Studio?
body: <p>I'm building an app with Android Studio, and one of my activities (which lets the user draw on a canvas) has a 'toolbar', with things like 'Clear', 'Undo', 'Redo' etc.</p>
  
  <p>I'm using the built-in icons for this - ie I go to the 'Drawables' folder, right-click, go to 'Add vector asset' and then select the appropriate icon.  I've figured out that I can change the size of the icon that gets added, but I can't figure out how to use that.</p>
  
  <p>So, on a phone screen, I'd like to use the standard 24dp icons. However, on a tablet screen, I'd like the icon to be bigger, as they're a bit lost on the bigger screen.</p>
  
  <p>I can't figure out how to do this, though, and I'm not even sure whether I'm using the right approach.  I know I can create different drawables sub-folders for different densities, but it's not so much the density that matters as the actual screen size.</p>
  
  <p>What's the best way to go about this?</p>
