This is the COVID-19 exposure notifications Android app for the Finnish Institute for Health and Welfare (THL). It uses Exposure Notifications API which is a joint effort between Apple and Google to provide the core functionality for building iOS and Android apps to notify users of possible exposure to confirmed COVID-19 cases.

Clone the repository, and open in Android Studio 4.0 or later (or build directly with Gradle).

Choose a build variant:

• liveDebug for real exposure notification system on a device. Note that using the exposure notification system is restricted by app id.
• simDebug for a simulated exposure notification system which provides dummy responses and allows running in emulator.

Configure the app for your local environment by creating a local.properties file in project root directory with entries that override defaults from gradle.properties. For example:

backendUrl=http://10.0.2.2:8080/
enableTestUI=true

See koronavilkku-backend for information on application backend.
