Mobistudy App

The participants' app of Mobistudy. The app is developed as an Apache Cordova app using the quasar framework as UI frontend.

Prerequisites

You need to install the following on your system:

• nodejs
• Apache Cordova
• (optional) the quasar command line tool

Install all other dependencies with:

npm install
cd src-cordova
npm install

If you're running any task which relates to the cordova plugins, make sure to create an empty 'www' directory under the src-cordova directory;

1. Cd into src-cordova
2. Run; mkdir www

Run the app in iOS

To run the app properly in iOS through Cordova, there are a couple of manual settings to be sorted out with Xcode.

Prepare the Xcode project:

cd src-cordova
cordova prepare ios

(if you get an error like "Conflict found, edit-config changes from config.xm will overwrite plugin.xml changes", repeat cordova prepare ios)

This will create a folder under src-cordova/platforms/ios Open that folder with Xcode. It will contain an iOS project. You need to make sure there is a valid signing profile for the app, at least for development. Try compiling the project and see if it works.

Also, you need to add the HealthKit capability.

Open the Mobistudy App-info.plist file located under Resources. Open it as source file. Then check that NSHealthShareUsageDescription and NSHealthUpdateUsageDescription are set. For example:

<key>NSHealthShareUsageDescription</key>
<string>The app needs to read health-related data from your phone</string>
<key>NSHealthUpdateUsageDescription</key>
<string>The app needs to store health-related data from your phone</string>

In order to be able to retrieve files that are stored in the app through iTunes, make sure the following also is present:

<key>UIFileSharingEnabled</key>
<true/>

For the pedometer to work properly:

<key>NSMotionUsageDescription</key>
<string>The app needs to detect steps</string>

For the GPS:

<key>NSLocationWhenInUseUsageDescription</key>
<string>The app needs to estimate your physical activity</string>

Run

To start the app in development mode (hot-code reloading, error reporting, etc.), run:

quasar dev

This will run in the browser, if you want to run it on a phone (supposing it's an iPhone):

quasar dev -m ios

Test

The repository contains some unit tests, to run them:

npm run test:unit

If you want to have quasar and the tests running in parallel and watching for code changes:

npm run concurrently:dev:jest

Develop

The code is consistent with how projects are structured in Quasar. If you use VS Code, follow the recommended settings from Quasar.

For development, you may want to mock some modules, see project.conf.js to activate mocked modules.

Deploy

iOS

Generate the compiled code.

quasar build -m ios

You need to open the project in Xcode, have a provisioning profile for distribution on the App Store and Archive then Distribute the app.

Android

Generate the compiled code.

quasar build -m android

Create a keystore (only once! not for every release).

keytool -genkey -v -keystore mobistudy-release.keystore -alias upload -keyalg RSA -keysize 2048 -validity 10000

Write down the password you set for the keystore and the certificate. Let's say it's "pwdpwd"

Then, inside src-cordova do:

cordova prepare android
cordova build android --release -- --keystore=mobistudy-release.keystore --alias=upload --storePassword=pwdpwd --password=pwdpwd

the APK will be available in src-cordova/platforms/android/app/build/outputs/apk/release/app-release.apk
