UPDATE:

This plugin is deprecated and will no longer be updated.
Our plugin contributed to placing the Health and Fitness use case in the Outsystems mobile plugins roadmap, and in case you missed it, a new official plugin was released and you can find it here.
There is also documentation available, here, that can help you start using it on your mobile app.

Please read the detail on the HealthPlugin component that has the necessary starting points to the documentation.

Besides that, to try this Demo application by your own, you will need to:
1. Configure a keystore and project on Google API Console (for Android devices & Google Fit). Get more details here.
2. Edit this application to configure the correct Bundle Id (which identifies the app that you are using to get/set data from/to Google Fit app - check image below).
3. You will need to have Google Fit installed and configured on your device. This is mandatory since the information that you are setting/retrieving comes from the data stored on the Google Fit app installed on your device.
