react-native-maps: Doesn't work on Android

Here is my component:

import React from 'react-native'
const {View, Text, ScrollView, Dimensions, StyleSheet} = React
import {observe} from 'JB/observeMixin'
import connectToStores from 'JB/connect'
import MapView from 'react-native-maps';


var { width, height } = Dimensions.get('window');

const ASPECT_RATIO = width / height;
const LATITUDE = 37.78825;
const LONGITUDE = -122.4324;
const LATITUDE_DELTA = 0.0922;
const LONGITUDE_DELTA = LATITUDE_DELTA * ASPECT_RATIO;


let hocs = compose(
  observe(loggedInUser$)
,
  connectToStores({
    jobs: 'employer.jobs',
    profile: 'user.profile',
  }, {
    changePage,
  })
)
export default hocs(class EmployerDashboard extends React.Component {
  constructor(props) {
    super(props)
    this.state = {
      hidemap: false,
      region: {
        latitude: LATITUDE,
        longitude: LONGITUDE,
        latitudeDelta: LATITUDE_DELTA,
        longitudeDelta: LONGITUDE_DELTA,
      },
    }
  }

  componentDidMount() {
    unfinishedJobs = [];
  }
  componentDidUpdate(prevProps, prevState) {
    unfinishedJobs = [];
  }

  // map example methods
  onRegionChange(region) {
    this.setState({ region });
  }

  jumpRandom() {
    this.setState({ region: this.randomRegion() });
  }

  animateRandom() {
    this.refs.map.animateToRegion(this.randomRegion());
  }

  randomRegion() {
    var { region } = this.state;
    return {
      ...this.state.region,
      latitude: region.latitude + (Math.random() - 0.5) * region.latitudeDelta / 2,
      longitude: region.longitude + (Math.random() - 0.5) * region.longitudeDelta / 2,
    };
  }


  render() {
    const {profile, jobs, Actions} = this.props
    const {hidemap} = this.state

    const goToPage = (...args) => _ => Actions.changePage(...args)
    const toggleMap = _ => this.setState({ hidemap: !hidemap })
    console.log('MapView', MapView)
    return (
      <View style={{
        position: 'absolute',
        top: 0,
        left: 0,
        right: 0,
        bottom: 0,
        justifyContent: 'flex-end',
        alignItems: 'center',
        backgroundColor: 'green'
      }}>

          <MapView
            ref="map"
            style={{
              position: 'absolute',
              top: 0,
              left: 0,
              right: 0,
              bottom: 0,
              backgroundColor: 'red'
            }}
            region={this.state.region}
            onRegionChange={this.onRegionChange.bind(this)}
          >
          </MapView>


          <MaterialButtonFixed 
            onPress={ goToPage('employer.hire', {unfinishedJobs}) }
            text='HIRE!'
          />

      </View>
    )
  }
})

"react": "^0.14.6",
"react-native": "^0.18.0",
"react-native-maps": "^0.2.3",

right now it works in iOS properly. In android i see only green background of the View container, nothing else

Also, please, mention in the installation guide that developer should have Google Play Services, Google Play Repository and Google Play APK Expansion Library installed in the android SDK.

By the way, may be I should have some other dependencies installed and this is the reason, why the map is not displayed in android in my case?
