How to build and run

Building the code

  • Make sure you have the Android SDK installed
  • Open the project in IntelliJ IDEA (2017.3 EAP recommended)
  • Create a file local.properties in the root directory of the project, pointing to your Android SDK installation. On Mac OS,
    the contents should be sdk.dir=/Users/<your username>/Library/Android/sdk. On other OSes, please adjust accordingly.
  • Run ./gradlew build

Running the backend

  • Run ./gradlew backend:run from the command line or from Gradle toolwindow
  • The backend will start serving on localhost:8080, with data stored in MySQL database

Running the Android app

  • Create a run configuration of type "Android App"
  • Select module "app" in the run configuration settings
  • Run the configuration
  • Select the emulator or connected device, as normal

Running the Web client

  • Make sure the backend is running on localhost:8080
  • Run gradlew :frontend:run in the 'web' directory to run webpack development server

Running iOS

  • This is quite simple, open the xcodeproject file with xCode and click on "play" button, that's all ;)
