Unable to Launch TabBar on Android

[chai2]

Hi, I just started implementing react-native-router-flux(Lovin it) for my app. It works like a charm for my IOS version. Trying the basic setup on Android, and I cant get to the TabBar view. Getting the following error. I looked up for the documentation for Navigator of React Native Android, and it find anything different when compared to iOS. Did anyone run into this issue?
