title: Visual Studio 2015 CTP 6 android emulator invalid device
body: <p>The android emulator in Visual Studio 2015 CTP 6 will not start. If I try to start a debug session with any native android c++ project on any android emulator (KitKat or Lollipop, phone or tablet) I'll get the error message:</p>
  
  <pre><code>"The device '' is invalid or not running.  Please switch to another device,  or use the Android Virtual Device (AVD) Manager to start a compatible emulator, or connect a compatible Android device."
  </code></pre>
  
  <p>I repaired and reinstalled Visual Studio and the Visual Studio android emulator already several times. </p>
