Install the library from npm:
npm install react-native-maps --save-exact
or
yarn add react-native-maps -E
The library ships with platform native code that needs to be compiled together with React Native. This requires you to configure your build tools.
Since React Native 0.60 and higher, autolinking makes the installation process simpler.
The actual map implementation depends on the platform. On Android, one has to use Google Maps, which in turn requires you to obtain an API key for the Android SDK.
On iOS, one can choose between Google Maps or the native Apple Maps implementation.
When using Google Maps on iOS, you need also to obtain an API key for the iOS SDK and include the Google Maps library in your build. The native Apple Maps based implementation works out-of-the-box and is therefore simpler to use at the price of missing some of the features supported by the Google Maps backend.
WARNING: Before you can start using the Google Maps Platform APIs and SDKs, you must sign up and create a billing account!
Run react-native link react-native-maps
after which you should be able
to use this library on iOS. Note that by default this will use Apple
Maps and you will miss some of the features provided by Google (see the
instruction on manually enabling Google Maps below).
If the CocoaPods package manager is new to you, please first review its installation guide
Setup your Podfile
(found at ios/Podfile
as below, replacing all
references to _YOUR_PROJECT_TARGET_
with your project target (it's the
same as project name by default).
# Uncomment the next line to define a global platform for your project
# platform :ios, '9.0'
target '_YOUR_PROJECT_TARGET_' do
rn_path = '../node_modules/react-native'
rn_maps_path = '../node_modules/react-native-maps'
# See http://facebook.github.io/react-native/docs/integration-with-existing-apps.html#configuring-cocoapods-dependencies
pod 'yoga', path: "#{rn_path}/ReactCommon/yoga/yoga.podspec"
pod 'React', path: rn_path, subspecs: [
'Core',
'CxxBridge',
'DevSupport',
'RCTActionSheet',
'RCTAnimation',
'RCTGeolocation',
'RCTImage',
'RCTLinkingIOS',
'RCTNetwork',

'RCTWebSocket',
]
# React Native third party dependencies podspecs
pod 'DoubleConversion', :podspec => "#{rn_path}/third-party-podspecs/DoubleConversion.podspec"
pod 'glog', :podspec => "#{rn_path}/third-party-podspecs/glog.podspec"
# If you are using React Native <0.54, you will get the following error:

end
post_install do |installer|
installer.pods_project.targets.each do |target|
if target.name == 'react-native-google-maps'
target.build_configurations.each do |config|
config.build_settings['CLANG_ENABLE_MODULES'] = 'No'
end
end
end
end
Then run in the ios
folder
pod install
and open the produced workspace file (.xcworkspace
) in XCode to build your project.
cd ios
pod install
The app's Info.plist
file must contain a NSLocationWhenInUseUsageDescription
with a user-facing purpose string explaining clearly and completely why your app needs the location, otherwise Apple will reject your app submission.
If you want to enable Google Maps on iOS, obtain the Google API key and
edit your AppDelegate.m
as follows:
+ #import <GoogleMaps/GoogleMaps.h>
@implementation AppDelegate
...
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
+ [GMSServices provideAPIKey:@"_YOUR_API_KEY_"]; // add this line using the api key obtained from Google Console
...
The [GMSServices provideAPIKey]
should be the first call of the method.
Then, do either of the following:
a) (React Native 0.59 and lower) If you are using CocoaPods to manage your dependecies, uncomment the
lines related to Google Maps from the Podfile
and run pod install
.
b) (React Native 0.59 and lower) If you used React Native link, you may include Google Maps manually as a
XCode framework following the instructions from SDK docs -> Install
manually. Then, to link this library to the framework, add the following to your
package.json
and replace the
REPLACE_ME_RELATIVE_PATH_TO_GOOGLE_MAPS_INSTALL
with the relative path
from your project root to the directory in which you installed the
Google Maps frameworks. You might need to specify a recursive search path
by adding a /**
at the end of the provided path (e.g. "./node_modules/react-native-maps/enable-google-maps 'ios/my-frameworks/GoogleMaps/**'"
{
"name": "your-app",
"scripts": {
"postinstall": "./node_modules/react-native-maps/enable-google-maps REPLACE_ME_RELATIVE_PATH_TO_GOOGLE_MAPS_INSTALL"
}
}
Re-run npm install
or yarn
to ensure the postinstall
script is run.
c) (React Native 0.60 and higher) Add the following to your Podfile above the use_native_modules!
function and run pod install
in the ios folder:
# React Native Maps dependencies
rn_maps_path = '../node_modules/react-native-maps'
pod 'react-native-google-maps', :path => rn_maps_path
pod 'GoogleMaps'
pod 'Google-Maps-iOS-Utils'
That's it, you made it! 👍
Ensure your build files match the following requirements:
- (React Native 0.59 and lower) Define the
react-native-maps
project inandroid/settings.gradle
:
...
include ':react-native-maps'
project(':react-native-maps').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-maps/lib/android')
- (React Native 0.59 and lower) Add the
react-native-maps
as an dependency of your app inandroid/app/build.gradle
:
...
dependencies {
...
implementation project(':react-native-maps')
}
3.1 (React Native all versions) If you've defined project-wide
properties
(recommended) in your root build.gradle
, this library will detect
the presence of the following properties:
buildscript {...}
allprojects {...}
/**
+ Project-wide Gradle configuration properties
*/
ext {
compileSdkVersion = xxx
targetSdkVersion = xxx
buildToolsVersion = "xxx"
minSdkVersion = xxx
supportLibVersion = "xxx"
playServicesVersion = "17.0.0" // or find latest version
androidMapsUtilsVersion = "xxx"
}
or do
buildscript {
ext {
buildToolsVersion = "xxx"
minSdkVersion = xxx
compileSdkVersion = xxx
targetSdkVersion = xxx
supportLibVersion = "xxx"
playServicesVersion = "17.0.0" // or find latest version
androidMapsUtilsVersion = "xxx"
}
}
...
You can find the latest playServicesVersion
by checking https://developers.google.com/android/guides/releases and searching for gms:play-services-maps:
3.2 (React Native all versions) If you do not have project-wide properties defined and have a different play-services version than the one included in this library, use the following instead (switch 10.0.1 for the desired version):
...
dependencies {
...
implementation(project(':react-native-maps')){
exclude group: 'com.google.android.gms', module: 'play-services-base'
exclude group: 'com.google.android.gms', module: 'play-services-maps'
}
implementation 'com.google.android.gms:play-services-base:10.0.1'
implementation 'com.google.android.gms:play-services-maps:10.0.1'
}
-
(React Native all versions) Specify your Google Maps API Key:
Add your API key to your manifest file (
android/app/src/main/AndroidManifest.xml
):
<application>
<!-- You will only need to add this meta-data tag, but make sure it's a child of application -->
<meta-data
android:name="com.google.android.geo.API_KEY"
android:value="Your Google maps API Key Here"/>
<!-- You will also only need to add this uses-libray tag -->
<uses-library android:name="org.apache.http.legacy" android:required="false"/>
</application>
Note: As shown above,
com.google.android.geo.API_KEY
is the recommended metadata name for the API key. A key with this name can be used to authenticate to multiple Google Maps-based APIs on the Android platform, including the Google Maps Android API. For backwards compatibility, the API also supports the namecom.google.android.maps.v2.API_KEY
. This legacy name allows authentication to the Android Maps API v2 only. An application can specify only one of the API key metadata names. If both are specified, the API throws an exception.

- (React Native 0.59 and lower) Add
import com.airbnb.android.react.maps.MapsPackage;
andnew MapsPackage()
in yourMainApplication.java
:
import com.airbnb.android.react.maps.MapsPackage;
...
@Override
protected List<ReactPackage> getPackages() {
return Arrays.<ReactPackage>asList(
new MainReactPackage(),
new MapsPackage()
);
}
- (React Native all versions) Ensure that you have Google Play Services installed:
- For the Genymotion emulator, you can follow these instructions.
- For a physical device you need to search on Google for 'Google Play Services'. There will be a link that takes you to the Play Store and from there you will see a button to update it (do not search within the Play Store).
That's it, you made it! 👍
If google logo/markers/polylines etc are displayed but the map
background is otherwise blank, this is likely an API key issue. Verify
your API keys and their restrictions. Ensure the native provideAPIKey
call is the first line of didFinishLaunchingWithOptions
.
Ensure also that the relevant Google APIs have been enabled for your project from the URLs below:
For reference, you may read the relevant issue reports: (#118, #176, #684).
Ensure the map component and its container have viewport dimensions. An example is below:
import MapView, { PROVIDER_GOOGLE } from 'react-native-maps'; // remove PROVIDER_GOOGLE import if not using Google Maps
...
const styles = StyleSheet.create({
container: {
...StyleSheet.absoluteFillObject,
height: 400,
width: 400,
justifyContent: 'flex-end',
alignItems: 'center',
},
map: {
...StyleSheet.absoluteFillObject,
},
});
export default () => (
<View style={styles.container}>
<MapView
provider={PROVIDER_GOOGLE} // remove if not using Google Maps
style={styles.map}
region={{
latitude: 37.78825,
longitude: -122.4324,
latitudeDelta: 0.015,
longitudeDelta: 0.0121,
}}
>
</MapView>
</View>
);
If your XCode project uses dynamic frameworks (e.g. you also have Swift
code in your project), you cannot install Google-Maps-iOS-Utils
with
CocoaPods. The issue and a workaround for it has been documented
here.
If you are trying to mount the map with the GOOGLE_PROVIDER
during
runtime, but your build has been configured for the Apple Maps backend,
a runtime exception will be raised.
In addition, when using Apple Maps, some Google-only functionalities have been disabled via runtime errors.
An exception will be raised if you try to use advanced features that depend on the Google Maps SDK for iOS. These include
- Making markers from KML files
- Heatmap rendering
- Marker clustering
- etc.
Run these commands to clean caches
# NPM
watchman watch-del-all
npm cache clean
# Android, if you encounter `com.android.dex.DexException: Multiple dex files define Landroid/support/v7/appcompat/R$anim`, then clear build folder.
cd android
./gradlew clean
cd ..
If you use Xcode with version less than 9 you may get use of undeclared identifier 'MKMapTypeMutedStandard'
or Entry, ":CFBundleIdentifier", Does Not Exist
errors. In this case you have to update your Xcode.
Make sure your Android studio is up to date and set up following the React Native docs.
In particular, the following packages have to be installed:
- Extras / Google Play services
- Extras / Google Repository
- Android 6.0 (API 23) / Google APIs Intel x86 Atom System Image Rev. 19
- Android SDK Build-tools 23.0.3
Be sure to have new MapsPackage()
in your MainApplication.java
:
import com.airbnb.android.react.maps.MapsPackage;
...
@Override
protected List<ReactPackage> getPackages() {
return Arrays.<ReactPackage>asList(
new MainReactPackage(),
new MapsPackage()
);
}

When starting Android emulator, make sure you have enabled
Wipe user data
. -
If you are using Android Virtual Devices (AVD), ensure that
Use Host GPU
is checked in the settings for your virtual device. -
If using an emulator and the only thing that shows up on the screen is the message:
[APPNAME] won't run without Google Play services which are not supported by your device.
, you need to change the emulator CPU/ABI setting to a system image that includes Google APIs. These may need to be downloaded from the Android SDK Manager first.In case you have multiple modules using Google Play Services such as
react-native-onesignal
, Make sure to exclude all the Google Play Services dependencies from the modules and import all the Google Play Services dependencies for all the modules in the project-widebuild.gradle
file like the following example:implementation(project(':react-native-onesignal')){ exclude group: 'com.google.android.gms' } implementation(project(':react-native-maps')){ exclude group: 'com.google.android.gms' } implementation 'com.google.android.gms:play-services-base:12.0.1' implementation 'com.google.android.gms:play-services-basement:12.0.1' implementation 'com.google.android.gms:play-services-location:12.0.1' implementation 'com.google.android.gms:play-services-tasks:12.0.1' implementation 'com.google.android.gms:play-services-maps:12.0.1'
- Make sure that your emulator has Google Play (Go to Android studio -> Virtual Devices -> Check that you have icon in "Play Store" column)
- Click to bottom dots icon in the emulator
- Go to Google Play Tab and click Update
If you don't use project-wide properties as per instructions above (not making changes to global android/build.gradle) and encounter at build time "Program type already present" error - add those lines to your android/app/build.gradle in the dependencies section:
dependencies {
...
implementation "com.android.support:appcompat-v7:${rootProject.ext.supportLibVersion}"
implementation "com.android.support:design:${rootProject.ext.supportLibVersion}"
implementation "com.android.support:support-v4:${rootProject.ext.supportLibVersion}"
}
