title: Android SDK - Installing system images?
body: <p>I am new to Android development. In Android Studio, I just installed every SDK under SDK Platforms. I noticed, though, when I click Show Package Details, that there are various System Images under each SDK version, called ARM EABI or Intel x86 Atom or Intel x86 Atom_64, and then the same things I just mentioned but with "Google APIs" prefix.</p>
  
  <p>Is it good practice to install all of the images?</p>
