Android Warning: Native component for "RCTMap" does not exist - reactjs

Question

I created a react native project and I am trying to use a map for Android. I am using airbnb react-native-maps package, as suggested in the Facebook react native page.
I followed the instructions, added my google api key in the manifest. In iOS it works perfectly, however on Android it gives me a warning and it does not show me the map: "Warning: Native component for 'RCTMap' does not exist".
Here is my code:
import React, { Component } from 'react';
import { Text, View, TouchableHighlight, MapView } from 'react-native';
import Header from '../common/header';
import HomeStyleSheet from '../../style/home/homeStyleSheet';
export default class Results extends Component{
//...
render(){
return (
<View style={{ marginTop: 20 }}>
<Header headerText='RESULTS'>
</Header>
<MapView
style={{ height: 300, marginLeft: 0, marginRight: 0 }}
showsUserLocation={true}
region={{
latitude: 43.683470,
longitude: -79.318006,
latitudeDelta: 0.03,
longitudeDelta:0.03
}}/>
<View style={{ height: 5, backgroundColor: 'blue' }}/>
</View>
);
}
}
What am I doing wrong? Why am I getting the warning? I searched similar problems here but almost everyone said to use airbnb react-native-maps (and l did). Thanks everyone

Answer 1

I can close the question. Between all the changes I did to make it work,I didn't realize I was importing MapView from 'react-native' instead of 'react-native-maps'. Fixed it:
import MapView from 'react-native-maps';
