Development

To run the application in the browser with live reload upon change detection run ionic serve in the project folder.

Please be aware that while developing in the browser on your computer, you cannot use the camera, devicemotion, or QR code scan.

To use these native features, you need to deploy the app natively on either iOS or Android (see instructions below)

Android deployment

An Android development environment is needed. Instructions for the setup were referenced from https://ionicframework.com/docs/developing/android. Tested on Windows 10.

Required software:

• Android Studio (AVD not needed)
• Android SDK (included in Studio)
• Node.js
• npm (included in Node.js)
• Gradle
• Ionic CLI
  • npm install -g @ionic/cli

Additional node packages needed:

npm install -g native-run
npm install -g cordova

Basic Instructions

Install all the required software.

Add the following to the Windows Path environment variable:

• Java SDK, Program Files\jdk-xxxx\bin
• Gradle, gradle-xxx\bin

Clone the repository.

Use this tool to check if the Android device is connected:
%USERPROFILE%\AppData\Local\Android\sdk\platform-tools\adb devices

Run ionic cordova run android --device

A debug version of the application will be built and uploaded to the Android device.

Tips

JDK 8

To download JDK 8 without an Oracle account, copy the Java SE Development Kit link for your platform from here. https://www.oracle.com/java/technologies/javase-jdk8-downloads.html

Then extract the part of the link after =nexturl and replace "otn" with "otn-bin" so it looks like the following.
https://download.oracle.com/otn-bin/java/jdk/8u241-b07/1f5b5a70bf22433b84d0e960903adac8/jdk-8u241-windows-x64.exe

Android SDK licenses

If the building fails because Android SDK licenses are not accepted, there is a work around.
Open Android Studio.
Go to Configure -> SDK Manager.
Install a random package, like Android SDK Command-line Tools.
It will prompt you to accept licenses.
