🔧 How to Setup

1. Install FuseOpen

   Download and install fuseopen from https://fuse-open.github.io

2. Install Fuse Preview

   Fuse is equipped with FusePreview app, to help developer preview the modification in realtime right in their device.

   • Android : https://play.google.com/store/apps/details?id=com.fusetools.fusepreview
   • iOS : https://itunes.apple.com/no/app/fuse-preview/id1296280076?mt=8

3. Install android SDK

   Android SDK is needed if you want to build your fuse into .apk file. You can install Android SDK using CLI,

   fuse install android
   

4. Development

   Open the project with FuseStudio to modify and preview the app during development. Please note that webview only running on device, it doesn't run on FuseStudio.

5. Configure app colors

   All the colors variable used in the app are stored in the /src/Resources.ux

   <Panel ux:Class="ColorResources">
     <float4 ux:Global="ColorMain"       		ux:Value="#445f8e"/>
     <float4 ux:Global="ColorButton"     		ux:Value="#759de3"/>
     <float4 ux:Global="ColorButtonDisable"	ux:Value="#a2a8c4"/>
     <float4 ux:Global="ColorBackground" 		ux:Value="#FFFFFF"/>
     <float4 ux:Global="ColorDark"       		ux:Value="#313131"/>
   </Panel>
   

6. App version checking

   App version checking works by comparing string from your fuse project located in /src/AppConfig.js with .json file from your server on fuse app startup.

   Thus, you have to put any accessible .json file in your server/cloud (i.e : http://yoursite.com/json/app-info.json), it should contain appVersion attribute as latest version of app in the playstore/appstore

   {
     "appVersion": "2.0.0"
   }

7. App configuration

   Before build your app, you need to setup some information used by the app in /src/AppConfig.js

   module.exports = {
     APP_OS: '', // your target app OS
     APP_VERSION: '', // current app version (i.e: 1.0.0)
     BASE_URL: '', // url of webview
     APP_INFO_JSON: '', // json file of latest app information
     PLAYSTORE_URL: '', // launch URL of your app in google play store, when user click update app
     APPSTORE_URL: '', // URL of your app in apple appstore, when user click update app
   }

8. Prepare your app icon

   Draw your appicon as .png file, the size is 192x192 px. Then upload the file to https://jgilfelt.github.io/AndroidAssetStudio/icons-launcher.html to generate android icon. Put the output in /src/assets/. Then set the value for each icon in the .unoproj file

   "Android": {
     "Icons": {
       "LDPI": "src/assets/drawable-mdpi/ic_launcher.png",
       "MDPI": "src/assets/drawable-mdpi/ic_launcher.png",
       "HDPI": "src/assets/drawable-hdpi/ic_launcher.png",
       "XHDPI": "src/assets/drawable-xhdpi/ic_launcher.png",
       "XXHDPI": "src/assets/drawable-xxhdpi/ic_launcher.png",
       "XXXHDPI": "src/assets/drawable-xxxhdpi/ic_launcher.png"
     }
   }
   

9. Build for production

   Build your app for production release, following this step https://fuse-open.github.io/docs/basics/preview-and-export.html

   fuse build --target=Android --configuration=Release
   

10. Grab the .apk file

    Grab the output .apk file in the build\Android\Release\[unoproj_name].apk

😎 Note for developer

• Module not found if require js using relative path. I dont know why. Thus, I use require js using absolute path in all js.
• Resource Color doesn't applied on builded app if using <ux:Resources>, thus using <Panel ux:Class=""> instead.
