React Native Navigation v1 to v2 adapter

• node >= 8
• react-native >= 0.51

npm uninstall react-native-navigation
npm install --save react-native-navigation-v1-v2-adapter

The adapter does its magic by swizzling a few method and adding another set of methods to the Navigation object. Therefor you need to ensure you're using the modified Navigation object and to do so, you have two options:

1. The easy way. Execute the adapter's static code first when your Js code starts running. Simply import Navigation from the adapter at the top of your index.js file.

   import {
     Navigation,
     ScreenVisibilityListener
   } from "react-native-navigation-v1-v2-adapter";

2. The hard way. Replace all import statements across your codebase:

   import {
     Navigation,
     ScreenVisibilityListener
   } from "react-native-navigation";

   With:

   import {
     Navigation,
     ScreenVisibilityListener
   } from "react-native-navigation-v1-v2-adapter";

First, make sure you have the 2.x version of React Native Navigation installed.

npm install --save react-native-navigation@2

or

yarn add react-native-navigation@2

2. 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).

   (it may install RNN v2 inside react-native-navigation-v1-v2-adapter, in such case the path will be: node_modules/react-native-navigation-v1-v2-adapter/node_modules/react-native-navigation/lib/ios/ReactNativeNavigation.xcodeproj

3. 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).

4. 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
   {
   	NSURL *jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index.ios" fallbackResource:nil];
   	[ReactNativeNavigation bootstrap:jsCodeLocation launchOptions:launchOptions];
   
   	return YES;
   }
   
   @end

1. update build.gradle

   buildscript {
       repositories {
           google()
           jcenter()
       }
       dependencies {
   -        classpath 'com.android.tools.build:gradle:3.0.1'
   +        classpath 'com.android.tools.build:gradle:3.1.2'
   
           // NOTE: Do not place your application dependencies here; they belong
           // in the individual module build.gradle files
       }
   }

2. Update gradle-wrapper.properties

    distributionBase=GRADLE_USER_HOME
    distributionPath=wrapper/dists
    zipStoreBase=GRADLE_USER_HOME
    zipStorePath=wrapper/dists
   -distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip
   +distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip

3. Update app/build.gradle

   android {
   	compileSdkVersion 25
   -        buildToolsVersion '26.0.2'
   +        buildToolsVersion '27.0.3'
   
   ...
   +   compileOptions {
   +       sourceCompatibility JavaVersion.VERSION_1_8
   +       targetCompatibility JavaVersion.VERSION_1_8
   +   }
   }
   
   dependencies {
   //   Change all `compile` statements to `implementation`
   -    compile fileTree(dir: 'libs', include: ['*.jar'])
   -    compile 'com.facebook.react:react-native:+'
   -    compile project(':react-native-navigation')
   +    implementation fileTree(dir: 'libs', include: ['*.jar'])
   +    implementation 'com.facebook.react:react-native:+'
   +    implementation project(':react-native-navigation')
    }

4. Update setting.gradle

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

5. Edit MainApplication.java - Only if your app has a single index file

   	```diff
   	public class MainApplication extends NavigationApplication {
   
   	-    @Nullable
   	-    @Override
   	-    public String getJSMainModuleName() {
   	-        return "index";
   	-    }
   

   • @Override
   • protected ReactNativeHost createReactNativeHost() {

   •    return new NavigationReactNativeHost(this) {
     

   •        @Override
     

   •        protected String getJSMainModuleName() {
     

   •            return "index";
     

   •        }
     

   •    };
     

   • } }

6. Edit MainActivity.java

   	```diff
   

   • public class MainActivity extends NavigationActivity {

   • public class MainActivity extends SplashActivity {

     	}
     
     	```
