title: How do I style or configure the react navigation tabs for android to fit
body: <p>I have a tab navigation using react native and <code>react-navigation</code>  My 5 tabs are too squished on android but look fine for iOS.  How do I style the tabs to fit on android?  Can I make the tabs horizontally scrollable?  I think I remember seeing that somewhere - is that standard android behavior?</p>
