Android example doesn't work

Hi,
Your `Example` project doesn't work properly, I get the following error:
`ReferenceError: Can't find variable: require (line1 in the generated bundle)`
Do you know why?

Additionally, I implement the tab on my own project, work very well in iOS, however, in Android I get the following error:
`undefined is not an object (evaluating 'el.props.name')`
The error occurred on line 29 of your `index.js`

Thanks for helping
