Requirements

Edge is known to build with this exact tool set. Updated versions of these toolsets may break the build or app. If you have issues, try mirroring these exact versions.

• MacOS High Sierra 10.13.3
• Xcode 10.1
• Android Studio 3.1.3
• CocoaPods 1.5.3
• Android NDK r15c This is a must have. Version r17 is known to break native code builds
• NodeJS 10.15.1
• NPM 6.4.1
• Yarn 1.10.1
• Java 1.8.0_152

Getting Started

Install nodejs (v 10.15.1 and npm (v 6.4.1)

https://nodejs.org/en/download/

Install yarn

https://yarnpkg.com

Install React Native CLI

npm install -g react-native-cli

Install CocoaPods (MacOS)

sudo gem install cocoapods

Checkout develop branch & install node_modules

cd edge-react-gui
yarn

XCode Setup - Use Legacy Build System

Open edge-react-gui/ios/edge.xcworkspace in Xcode
File -> Workspace Settings
Set `Build System` to `Legacy Build System`

Android NDK Setup

*IMPORTANT* You must use version r15c to build. r17 and above break NDK build that this app requires. Download
the r15c NDK version here: https://developer.android.com/ndk/downloads/older_releases

(MacOS) If the NDK is already installed from Android Studio, it should be in `/Users/[user]/Library/Android/sdk/ndk-bundle`.
If you are using a version other than r15c, replace your version with version r15c downloaded from above

Set the following environment vars

export ANDROID_NDK_HOME=/Users/[username]/Library/Android/sdk/ndk-bundle
export NDK_HOME=/Users/[username]/Library/Android/sdk/ndk-bundle
export SDK_HOME=/Users/[username]/Library/Android/sdk
export JAVA_HOME="/Applications/Android Studio.app/Contents/jre/jdk/Contents/Home"

Android Recommended Versioning & Configuration

For best results, please consider using the following versions (up-to-date as of 2018-05-11)

• Java & Jave JDK version 8u171

Add API key in env.json

A public API key is built into the edge-core-js which can be used to build and test the Edge app. This key is severely rate limited and should not be used for production. For production use, get an API key by emailing [email protected].

Copy the env.example.json to env.json and change the AIRBITZ_API_KEY to the API key you received from Edge. To use the public API key, leave AIRBITZ_API_KEY blank.

Run the app in debug mode

iOS

• Open edge-react-gui/ios/edge.xcworkspace in Xcode
• Choose a target device or simulator and tap the Play button on the top nav bar

Android

cd android
./gradlew assembleDebug

• The resulting APK will be in ./app/build/outputs/apk/debug/app-debug.apk
• Copy the APK to a simulator like Genymotion or a real device via Email or messaging app

Build release version of app

iOS

• Open edge-react-gui/ios/edge.xcworkspace in Xcode
• Hold [ option/alt ] and click on the Edge button on the top bar to the right of the Play and Stop icons.
• Change 'Build Configuration' to Release
• Uncheck 'Debug Executable'
• Close window
• Choose a device and hit Play

Android

cd android
./gradlew assembleRelease

• The resulting APK will be in ./app/build/outputs/apk/release/app-release.apk
• Copy the APK to a simulator like Genymotion or a real device via Email or messaging app

Deploying (MacOS Only)

The included deploy.js is a script to automate building, signing, and deploying release builds of Edge. It provides the following:

• Auto set app version number based on package.json version
• Auto increment and set the buildnum to the value of YYMMDDNN where NN is an auto-incrementing build number within a day
• Auto sign Android APK with Android keystore files
• Auto sign iOS IPA with provisioning profiles

To Use

• Set the env var KEYCHAIN_PASSWORD to the keychain password of the current user
• Copy the deploy-config.sample.json to deploy-config.json and edit the parameters accordingly. You'll need a HockeyApp account to get ids and keys
• Put any Android keystore files into edge-react-gui/keystores/
• If using Firebase, put your account's google-services.json and GoogleService-Info.plist into edge-react-gui/
• Install xcpretty sudo gem install xcpretty

Run deploy

./deploy.js edge ios master
./deploy.js edge android master
