title: Why did installing Crosswalk affect non Intel XDK app
body: <p>I am currently try to find a viable option to incorporate webRtc into an Android &amp; ios app using Cordova /phonegap/ionic and I have tried getting the following examples to work but till recently I have had no luck:</p>
  
  <p><a href="https://github.com/songz/cordova-plugin-opentok" rel="nofollow noreferrer">https://github.com/songz/cordova-plugin-opentok</a> </p>
  
  <p><a href="https://github.com/gomobile/sample-webrtc-video-client" rel="nofollow noreferrer">https://github.com/gomobile/sample-webrtc-video-client</a></p>
  
  <p><a href="https://github.com/alongubkin/phonertc" rel="nofollow noreferrer">https://github.com/alongubkin/phonertc</a>
  (phoneRtc was an issue only because it had no working examples and I found the docs lacking)
  I was able to get the 1st two deployed correctly with no issue but every time I did so I could not get a video feed from my camera, all I got was the following:</p>
  
  <p>OpenTok plugin:</p>
  
  <p><img src="https://i.stack.imgur.com/D6G94.png" alt="OpenTok plugin"></p>
  
  <p>Intel XDK sample-webrtc-video-client:</p>
  
  <p><img src="https://i.stack.imgur.com/gGwtS.png" alt="enter image description here"></p>
  
  <p>When I tried to Debug the OpenTok app I the following error:</p>
  
  <pre><code>OT.exception :: title: Connection Failed (1013) msg: Publisher PeerConnection Error: The video stream failed to connect. Please notify the site owner if this continues to happen.
  </code></pre>
  
  <p>and when I tried to debug the Intel XDK example It prompeted me to install <code>Intel App Preview</code> and when it relaunched the sample App to debug it prompted me to update <code>Intel App Preview Crosswalk</code> and then the App worked...</p>
  
  <p>What's confusing me is now the OpenTok app also works....Can someone shed some light on this?
  did this install some global library or something? I have tried googling this but cannot seem to find an explaination that helps me to understand how or why this happens as I saw no mention of Crosswalk in the OpenTok application.</p>
