title: React-native - Unable to build after configuring React Native Facebook SDK
body: <p>I followed the instructions on Facebook and npmjs. I even have tried cd.. android &amp;&amp; gradlew clean and the clean failed also. I have restarted my computer several times but to no avail. Please can anyone tell me where I got this wrong? I am building the app on Windows.</p>
