title: Android development using react native
body: <p>When I'm running <code>npm run android</code> in cmd to run react-native code into my Android device an error is raising. The error is <code>**Could not initialize class org.codehaus.groovy.runtime.InvokerHelper**</code>. I have followed the documentation of React Native website. But I can not figure out the error. Please help.</p>
