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

Use Android Studio's Preferences to install NDK (Side by side):

Set the following environment vars

The following environment variables should be exported from your .bashrc or equivalent file.

Android Recommended Versioning & Configuration

For best results, please consider using the following versions (up-to-date as of 2020-11-16)

• Java 8 & Java JDK version 8u202 ((link))

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 info@edge.app.

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

First, run ./scripts/updateVersion.js to copy the package.json version into the native project files, and to assign a unique build number.

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 sign Android APK with Android keystore files
• Auto sign iOS IPA with provisioning profiles

To Use

• Run ./scripts/updateVersion.js to set up your build number & version.
• 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

Debugging

As with any modern React Native app, Flipper is the officially-supported debugging app. Use the "React Native Hermes Debugger" to debug Javascript running in the UI.

If you want to inspect Redux, you can install the redux-debugger plugin for Flipper, which this app supports.
