/**
 * React component that wraps the platform `DrawerLayout` (Android only). The
 * Drawer (typically used for navigation) is rendered with `renderNavigationView`
 * and direct children are the main view (where your content goes). The navigation
 * view is initially not visible on the screen, but can be pulled in from the
 * side of the window specified by the `drawerPosition` prop and its width can
 * be set by the `drawerWidth` prop.
 *
 * Example:
 *
 * ```
 * render: function() {
 *   var navigationView = (
 *     <View style={{flex: 1, backgroundColor: '#fff'}}>
 *       <Text style={{margin: 10, fontSize: 15, textAlign: 'left'}}>I'm in the Drawer!</Text>
 *     </View>
 *   );
 *   return (
 *     <DrawerLayoutAndroid
 *       drawerWidth={300}
 *       drawerPosition="left"
 *       renderNavigationView={() => navigationView}>
 *       <View style={{flex: 1, alignItems: 'center'}}>
 *         <Text style={{margin: 10, fontSize: 15, textAlign: 'right'}}>Hello</Text>
 *         <Text style={{margin: 10, fontSize: 15, textAlign: 'right'}}>World!</Text>
 *       </View>
