title: 71mb added to app size for crosswalk
body: <p>I really hope I'm doing something wrong. I've added crosswalk to a project and have had some serious app size increase. To test I've done the following.</p>
  
  <ol>
  <li>created a new ionic project</li>
  <li>added my app code to /www/</li>
  <li>added ngcordova and various plugins</li>
  <li>Ran ionic build and drop the apk onto a Genymotion emulator. The app was very slow but had a app size of 8.01mb (once installed - checked with app manager).</li>
  <li>Then I deleted the app from the emulator</li>
  <li>Ran <code>ionic browser add crosswalk</code></li>
  <li>Ran <code>ionic run android</code> which installed the correct .apk on the emulator. On checking in manage apps the app size is now 79.36mb!!! Thats a 71mb increase! Most places say 20mb at most but 71mb!!!</li>
  </ol>
  
  <p>Can someone tell me what I've done wrong?</p>
  
  <p>When I added the Android SDK I did add all the tools ad platforms availabe in the SDK manager, did that have some effect?</p>
  
  <p>If this isn's fixable it's a show stopper for me, which is a shame after spending weeks developing an app...</p>
  
  <p>Please help!</p>
