title: create react native app expo failed to connect running on emulator in same computer
body: <p>I'm new to react native, I've used <em>create-react-native-app</em> command to generate a project, executed <em>npm start</em> to start the packager. Until now all is good, the packager is running on address 192.168.232.56:19000, it shows me the QR code and the menu, but when I hit <strong>a</strong> to start the app in the emulator, the expo app shows:</p>
  
  <p><strong>Something went wrong, could not load exp://192.168.232.56:19000</strong> </p>
  
  <p>with the log stating </p>
  
  <p><strong>ConnectException: Failed to connect to /192.168.232.56:19000</strong></p>
  
  <p>usning the browser in the emulator I can freely surf the internet, so there is connection </p>
  
  <p>Any help greatle appreciated!! (just to clarify, the emulator is running in the same computer where I develop and the packager is running)</p>
  
  <p><strong>UPDATE:</strong> accessing address <em>10.0.2.2:19000</em> from the browser in the emulator throws the following json:</p>
