title: Android Studio: Build type release /debug - what relevance does this have?
body: <p>I just created an apk via android studio and it gave me an option of creating my own key, which i did but then asked me what type of build it is i.e. debug or release. Also list of flavours, which none exists.</p>
  
  <p>Where is this information setup, in the gradle file ?</p>
  
  <p>So if I leave build type set to Release, what relevance does this have.</p>
  
  <p>I am having problems sourcing any documentation on this.</p>
  
  <p>Any ideas?</p>
