title: CommandInvokationFailure: : Unable to forward network traffic to device in Unity
body: <p>I installed Unity and following tutorial from <a href="https://developers.google.com/ar/develop/unity/quickstart-android" rel="nofollow noreferrer">GoogleAR</a>.</p>
  
  <p>I faced some difficulties and managed till installation of app in mobile by lot of internet search.</p>
  
  <p>Now, the app is installed in my Android mobile by unity, but not opening by itself due to the following error</p>
  
  <blockquote>
    <p>CommandInvokationFailure: Unable to forward network traffic to device.
    Please make sure the Android SDK is installed and is properly
    configured in the Editor. See the Console for more details. /home/_____/Android/Sdk/platform-tools/adb -s "<em>number</em>" forward "tcp:34999" "localabstract:Unity-com.example.helloAR"</p>
  </blockquote>
  
  <p>What causes this issue and how to overcome it?</p>
  
  <p>Note that I did un-check Development Build, but still not working.</p>
