This is source code of UNA mobile apps for iOS and Android based on ReactNative.
Mobile apps need to have Nexus UNA app installed.

You need to have npm, react-native along with Android SDK and/or XCode along withg CocoaPods installed to build apps.

After downloading source code, unpacking it, then run:

npm install 

Then you can already try to run Andoid app with the following commands (Android emulator must be already running):

export ANDROID_HOME=/path/to/android/sdk
react-native run-android

or iOS app (on Mac OSX only):

cd ios; pod install; cd ..
react-native run-ios

Lest assume that you want to rename app to Kookaburra and site name is kookaburra.io.
Then you need to change the following strings:

UNA.IO => Kookaburra
com.una.android => com.kookaburra.android
com.una.ios => com.kookaburra.ios
una.io => kookaburra.io
una => kookaburra

In the following files and some files need to be renamed:

App.js
app.json
package.json

ios/Podfile
ios/una/AppDelegate.m

android/app/src/main/res/values/strings.xml
android/app/src/main/java/com/una/android/MainActivity.java => android/app/src/main/java/com/kookaburra/android/MainActivity.java
android/app/src/main/java/com/una/android/MainApplication.java => android/app/src/main/java/com/kookaburra/android/MainApplication.java
android/app/src/main/AndroidManifest.xml
android/app/BUCK
android/app/build.gradle

In XCode change the following (make sure to open una.xcworkspace):

Then rename the following file:

ios/kookaburra.xcodeproj/xcshareddata/xcschemes/una.xcscheme => ios/kookaburra.xcodeproj/xcshareddata/xcschemes/kookaburra.xcscheme

Change all images to your own in /img/ folder, leaving the same images dimensions.

To change launcher and icons for iOS and Android apps it's recommended to use special script, it can be installed using the following command:

npm i -D @bam.tech/react-native-make

Then you can generate app icons for Android using the following command:

react-native set-icon --platform android --path ./img/icon-android.png

To generate splash for Android, some trick is needed (make sure that you replace Kookaburra with your own app name):
Change "name": "kookaburra" in package.json file to "name": "kookaburra/android".
Then run the following command:

react-native set-splash --platform android --path ./img/background.png --resize contain

Then change "name": "kookaburra/android" back to "name": "kookaburra" in package.json file.

Changing splash and app icon for iOS app requires similar trick:
Change "name": "kookaburra" in package.json file to "name": "una".
Then run the following commands:

react-native set-icon --platform ios --path ./img/icon.png
react-native set-splash --platform ios --path ./img/background.png --resize contain

Then change "name": "una" back to "name": "kookaburra" in package.json file.
