Android Emulator not showing Google Maps on Screen

Question

I have been trying to follow this https://github.com/airbnb/react-native-maps tutorial I tried everything they said but getting a blank screen on my emulator of android studio.

My Code:

import React, { Component } from 'react';
import {
  AppRegistry,
  StyleSheet,
  Text,
  View
} from 'react-native';

import MapView from 'react-native-maps';

export default class ReactNativeMaps extends Component {
  render() {
   const { region } = this.props;
   console.log(region);

   return (
     <View style ={styles.container}>
       <MapView
         style={styles.map}
         region={{
           latitude: 39.1329,
           longitude: 84.5150,
           latitudeDelta: 0.015,
           longitudeDelta: 0.0121,
         }}
       >
       </MapView>
     </View>
   );
 }
}

const styles = StyleSheet.create({
  container: {
    position: 'absolute',
    top: 0,
    left: 0,
    right: 0,
    bottom: 0,
    justifyContent: 'flex-end',
    alignItems: 'center',
  },
  map: {
    position: 'absolute',
    top: 0,
    left: 0,
    right: 0,
    bottom: 0,
  },
});

AppRegistry.registerComponent('ReactNativeMaps', () => ReactNativeMaps);

AndroidManifest.xml File:

Answer 1

I had similar problem and spent a lot of time before solve it. Usually all was OK on real device, but fails to show Google Map on some of my emulator variants. Obviously, the program code was OK, so the question was why?

What I have observed so far:

1. If hardware acceleration is disabled - all is back working.

2. If use pure android image, cpu-arm (not accelerated x86, it was slower), but also works.

3. If you are under x86_64 OS - macOS 10.13.2 in my case, USE x86_64 version of emulator image, instead of universal x86!!! That was my major mistake to do not get it works! Replacing my emulator's image with x86_64 variants, solve all of them!
