Simple React Native Map Example to integrate the Map into RN App

React Native Map Example is to integrate the Google Map into your React Native Application. To integrate the Map in our example we will use a very good library called react-native-maps. Which provides MapView component which is very easy to use. So let’s get started.

To Make a React Native App

Getting started with React Native will help you to know more about the way you can make a React Native project. We are going to use react-native init to make our React Native App. Assuming that you have node installed, you can use npm to install the react-native-cli command line utility. Open the terminal and go to the workspace and run

npm install -g react-native-cli

Run the following commands to create a new React Native project

react-native init ProjectName

This will make a project structure with an index file named App.js in your project directory.

Installation of Dependency

To use MapView we need to install react-native-maps package. To install this

Open the terminal and jump into your project

cd ProjectName

1	cd ProjectName

Run the following command

npm install react-native-maps --save

1	npm install react-native-maps --save

This command will copy all the dependencies into your node_module directory, You can find the directory in node_module the directory named react-native-maps.

–save is optional, it is just to update the react-native-maps dependancy in your package.json file.

Linking of Library

To use react-native-maps library we have to link some dependencies in Android and IOS project files. In order to link the library, you have to run following command

react-native link

1	react-native link

You can see the result like this

You can see the following changes in your android project. If you are unable to find the changes then please do those changes as they are must for this example.

Go to the MapExample> android > app > build.gradle.
Scroll down and you can see the following dependency and if not please add this.

compile project(':react-native-maps')

1	compile project(':react-native-maps')

Open MapExample> android > settings.gradle and you can see the following lines and if not please add this.

include ':react-native-maps'
project(':react-native-maps').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-maps/lib/android')

1 2	include ':react-native-maps' project(':react-native-maps').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-maps/lib/android')

Open MapExample> android > app > src > main > java > com > mapexample> MainApplication.java and you can see the following lines in imports if not then please add

import com.airbnb.android.react.maps.MapsPackage;

1	import com.airbnb.android.react.maps.MapsPackage;

Scroll down and you can see the following line in getPackages after new MainReactPackage() if not then please add a comma(,) and add

new MapsPackage()

1	new MapsPackage()

Here we have done with our installation of the library. If you are still facing the trouble please comment below so that we can help you out from the problem.

Generate the API Key

To use Map in your Application we have to get Map API key from the Google Developer console. For that, open Developer console and log in from your Google account.

If you have already created any project you can use that or you can create a new one like this

After creating the project you can see all of your created project a drop down in the top left corner. Now select the project from the dropdown and goto to the credential section.

You can find the create credential option there.

Hit on the create credential button and it will create an API key to the user in your Map Application

Before we add this API key in our project you have to enable the API which you want to use in your project. For that, you can search for the Map and you will find the Map related API. We will enable Map SDK for Android because we are making this example for the Android. So click on Map SDK for Android and you will found the enable button to enable the Map API for Android.

Now after enabling the API key, we have to add this API key to our project’s AndroidManifest.xml file. Just copy the following lines and paste it into your manifest file with your generated API key.

<meta-data
  android:name="com.google.android.geo.API_KEY"
  android:value="Replace this with your API key"/>

<meta-data

android:name="com.google.android.geo.API_KEY"

android:value="Replace this with your API key"/>

You can download the source code from Github

Open App.js in any code editor and replace the code with the following code

App.js

/*This is an Example of React Native Map*/
import React from 'react';
import { StyleSheet, Text, View } from 'react-native';
import MapView from 'react-native-maps';

export default class App extends React.Component {
  render() {
    return (
      <View style={styles.container}>
        <MapView
          style={styles.map}
          initialRegion={{
            latitude: 37.78825,
            longitude: -122.4324,
            latitudeDelta: 0.0922,
            longitudeDelta: 0.0421,
          }}
        />
      </View>
    );
  }
}

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

/*This is an Example of React Native Map*/

import React from 'react';

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

import MapView from 'react-native-maps';

export default class App extends React.Component {

render() {

return (

<MapView

style={styles.map}

initialRegion={{

latitude: 37.78825,

longitude: -122.4324,

latitudeDelta: 0.0922,

longitudeDelta: 0.0421,

}}

</View>

);

}

const styles = StyleSheet.create({

container: {

position:'absolute',

top:0,

left:0,

right:0,

bottom:0,

alignItems: 'center',

justifyContent: 'flex-end',

map: {

position:'absolute',

top:0,

left:0,

right:0,

bottom:0,

});

To Run the React Native App

Open the terminal again and jump into your project using.

cd ProjectName

To run the project on an Android Virtual Device or on real debugging device

react-native run-android

or on the iOS Simulator by running

react-native run-ios (macOS only).

This is how you can integrate Google Map in your React Native Application. If you have any doubt or you want to share something about the topic you can comment below or contact us here. There will be more posts coming soon. Stay tuned!

Hope you liked it. 🙂

Are you using the same StyleSheet?
const styles = StyleSheet.create({
container: {
position:’absolute’,
top:0,
left:0,
right:0,
bottom:0,
alignItems: ‘center’,
justifyContent: ‘flex-end’,
},
map: {
position:’absolute’,
top:0,
left:0,
right:0,
bottom:0,
},
});

  Thank you for your response and I fixed the issue. I was used hybrid Google map key during the development. Now I changed the android native app key. Now working fine.

      Yes, I know the Map is giving this problem with the updated 0.59 version. I am working on it and will update the example in 1-2 days. Thank you for your comment to provide me the information about the error. I’ll mail you regarding the update.

      cái này là do React-native-maps. Bạn chạy npm install –save “react-native-maps@react-native-community/react-native-maps#master là đc ngay.
      This is because React-native-maps. You run npm install –save “react-native-maps @ react-native-community / react-native-maps # master is right away.
