Installation

Requirements

• node >= 8
• react-native >= 0.51

npm or yarn

• npm install --save react-native-navigation

...or if you use yarn:

• yarn add react-native-navigation

Installing with npx rnn-link

If you're using RN 0.60 or higher, you can benefit from autolinking for some of the necessary installation steps. But unlike most other libraries, react-native-navigation requires you to make a few changes to native files.

We've simplified the process through a set of scripts. So to make all the necessary changes automatically, in your project's root folder run:

npx rnn-link

Make sure to commit the changes introduced by the rnn-link script.

The automatic linking is optimized for new applications created via the react-native init command. If you are migrating from a version of react-native-navigation older than v5, it's recommended to check the steps manually after the script runs.

If the link script completed successfully, you're good to go! No more native configuration is required.

If one of the steps failed or you can't run (or are not comfortable with) the automatic scripts, you'll need to complete the relevant steps in the manual installation steps below, for both platforms.

Displaying the app root

Update index.js file

index.js is typically used as an entry point into the app. It's first parsed and executed by the JS engine, therefore we'll want to show our UI from there.

The following diff demonstrates changes needed to be made to index.js, initialized by react-native init.

+import { Navigation } from "react-native-navigation";

-import {AppRegistry} from 'react-native';

import App from "./App";

-import {name as appName} from './app.json';

-AppRegistry.registerComponent(appName, () => App);

+Navigation.registerComponent('com.myApp.WelcomeScreen', () => App);

+Navigation.events().registerAppLaunchedListener(() => {

+ Navigation.setRoot({

+ root: {

+ stack: {

+ children: [

+ {

+ component: {

+ name: 'com.myApp.WelcomeScreen'

+ }

+ }

+ ]

+ }

+ }

+ });

+});

If you followed the steps successfully up to this point, then this should be all!

tip

This is a good moment to build your application in both platforms, validate that everything is working properly and commit your changes. If you're coming from a fresh react-native init project, then you should be seeing the Welcome screen as usual, but under the hood your application is using react-native-navigation!

Manual Installation

If installation with npx rnn-link did not work, follow the manual installation steps below.

iOS

Make sure your Xcode is updated. We recommend editing .h and .m files in Xcode as the IDE will usually point out common errors.

Installation with CocoaPods

Projects generated using newer versions of react-native use CocoaPods by default. In that case it's easier to install react-native-navigation using CocoaPods.

1. Update your Podfile: If you're upgrading to v5 from a previous RNN version, make sure to remove manual linking of RNN

platform :ios, '9.0'

require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'

target 'YourApp' do

# Pods for YourApp

pod 'React', :path => '../node_modules/react-native/'

2. cd ios && pod install

Native Installation

If the React Native version in your project is above 0.60 and you are following the manual installation, skip to step 3.

If autolinking is not available in your project (RN version < 0.60), you can always try and install the hardcore way:

1. In Xcode, in Project Navigator (left pane), right-click on the Libraries > Add files to [project name]. Add node_modules/react-native-navigation/lib/ios/ReactNativeNavigation.xcodeproj (screenshots).

2. In Xcode, in Project Navigator (left pane), click on your project (top), then click on your target row (on the "project and targets list", which is on the left column of the right pane) and select the Build Phases tab (right pane). In the Link Binary With Libraries section add libReactNativeNavigation.a (screenshots).

   a. If you're seeing an error message in Xcode such as:

   'ReactNativeNavigation/ReactNativeNavigation.h' file not found.

   You may also need to add a Header Search Path: (screenshots).

   $(SRCROOT)/../node_modules/react-native-navigation/lib/ios

3. In Xcode, you will need to edit this file: AppDelegate.m. This function is the main entry point for your app:

   - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { ... }

   Its content should look like this:

   #import "AppDelegate.h"

   #import <React/RCTBundleURLProvider.h>

   #import <React/RCTRootView.h>

   #import <ReactNativeNavigation/ReactNativeNavigation.h>

   @implementation AppDelegate

   -(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

   {

   [ReactNativeNavigation bootstrapWithDelegate:self launchOptions:launchOptions];

   return YES;

   }

   -(NSURL *)sourceURLForBridge:(RCTBridge *)bridge

   {

   #if DEBUG

   return [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];

   #else

   return [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];

   #endif

   }

   @end

   a. If, in Xcode, you see the following error message in AppDelegate.m next to #import "RCTBundleURLProvider.h":

   ! 'RCTBundleURLProvider.h' file not found

   This is because the React scheme is missing from your project. You can verify this by opening the Product menu and the Scheme submenu. To make the React scheme available to your project, run npm install -g react-native-git-upgrade followed by react-native-git-upgrade. Once this is done, you can click back to the menu in Xcode: Product -> Scheme -> Manage Schemes, then click '+' to add a new scheme. From the Target menu, select "React", and click the checkbox to make the scheme shared. This should make the error disappear.

Android

Make sure your Android Studio installation is up to date. We recommend editing gradle and java files in Android Studio as the IDE will suggest fixes and point out errors, this way you avoid most common pitfalls.

1 Update android/build.gradle:

buildscript {

ext {

- minSdkVersion = 16

+ minSdkVersion = 19 // Or higher

compileSdkVersion = 26

targetSdkVersion = 26

supportLibVersion = "26.1.0"

+ kotlinVersion = "1.3.72" // Or any version above 1.3.x

+ RNNKotlinVersion = kotlinVersion

}

repositories {

google()

jcenter()

+ mavenLocal()

+ mavenCentral()

}

dependencies {

+ classpath("org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlinVersion")

+ classpath 'com.android.tools.build:gradle:3.5.3' // Or higher

- classpath 'com.android.tools.build:gradle:2.2.3'

}

}

allprojects {

repositories {

+ google()

mavenLocal()

jcenter()

maven {

// All of React Native (JS, Obj-C sources, Android binaries) is installed from npm

url "$rootDir/../node_modules/react-native/android"

}

- maven {

- url 'https://maven.google.com/'

- name 'Google'

- }

+ maven { url 'https://jitpack.io' }

}

}

2 Update MainActivity.java

MainActivity.java should extend com.reactnativenavigation.NavigationActivity instead of ReactActivity.

This file is located in android/app/src/main/java/com/<yourproject>/MainActivity.java.

-import com.facebook.react.ReactActivity;

+import com.reactnativenavigation.NavigationActivity;

-public class MainActivity extends ReactActivity {

+public class MainActivity extends NavigationActivity {

- @Override

- protected String getMainComponentName() {

- return "yourproject";

- }

}

If you have any react-native related methods, you can safely delete them.

3 Update MainApplication.java

This file is located in android/app/src/main/java/com/<yourproject>/MainApplication.java.

...

import android.app.Application;

import com.facebook.react.ReactApplication;

import com.facebook.react.ReactNativeHost;

import com.facebook.react.ReactPackage;

import com.facebook.react.shell.MainReactPackage;

import com.facebook.soloader.SoLoader;

+import com.reactnativenavigation.NavigationApplication;

+import com.reactnativenavigation.react.NavigationReactNativeHost;

-public class MainApplication extends Application implements ReactApplication {

+public class MainApplication extends NavigationApplication {

private final ReactNativeHost mReactNativeHost =

- new ReactNativeHost(this) {

+ new NavigationReactNativeHost(this) {

@Override

public boolean getUseDeveloperSupport() {

return BuildConfig.DEBUG;

}

@Override

protected List<ReactPackage> getPackages() {

@SuppressWarnings("UnnecessaryLocalVariable")

List<ReactPackage> packages = new PackageList(this).getPackages();

// Packages that cannot be autolinked yet can be added manually here, for example:

// packages.add(new MyReactNativePackage());

return packages;

}

@Override

protected String getJSMainModuleName() {

return "index";

}

};

@Override

public ReactNativeHost getReactNativeHost() {

return mReactNativeHost;

}

@Override

public void onCreate() {

super.onCreate();

- SoLoader.init(this, /* native exopackage */ false);

initializeFlipper(this, getReactNativeHost().getReactInstanceManager());

}

}

App root

Now that you're done, don't forget to update the index.js file, as shown above.

Troubleshooting

Build app with gradle command

prefered solution - The RNN flavor you would like to build is specified in app/build.gradle. Therefore in order to compile only that flavor, instead of building your entire project using ./gradlew assembleDebug, you should instruct gradle to build the app module: ./gradlew app:assembleDebug. The easiest way is to add a package.json command to build and install your debug Android APK .

"scripts": {

...

"android": "cd ./android && ./gradlew app:assembleDebug && ./gradlew installDebug"

}

Now run npm run android to build your application

Force the same support library version across all dependencies

Some of your dependencies might require a different version of one of Google's support library packages. This results in compilation errors similar to this:

FAILURE: Build failed with an exception.

* What went wrong:

Execution failed for task ':app:preDebugBuild'.

> Android dependency 'com.android.support:design' has different version for the compile (25.4.0) and runtime (26.1.0) classpath. You should manually set the same version via DependencyResolution

To resolve these conflicts, add the following to your app/build.gradle:

android {

...

}

configurations.all {

resolutionStrategy.eachDependency { DependencyResolveDetails details ->

def requested = details.requested

if (requested.group == 'com.android.support' && requested.name != 'multidex') {

details.useVersion "${rootProject.ext.supportLibVersion}"

}

}

}

dependencies {

...

implementation 'com.android.support:design:25.4.0'

implementation "com.android.support:appcompat-v7:${rootProject.ext.supportLibVersion}"

}
