title: Using Android Studio with minimum disk space
body: <p>I have limited disk space and want to start developing android, but it seems that android studio eats a lot of memory! some says it took more than 20 GB.</p>
  
  <p>So the question is: what are the minimum necessary components (android platforms, emulator, ...) to start and how can we use android studio with the most possible minimality?</p>
  
  <p>Also, how does adding each of these components (that are respectively unnecessary) affects the used space?</p>
