How can the companion app retrieve sleep data from the Fitbit Android app?

[Sleepybug]

Hello! I'm working on the companion app for Fitbit on Android, and I need to retrieve users' sleep data for my application. Could you please share how the companion app can obtain this data through the Fitbit Android app? Alternatively, are there any alternative methods for accessing this data through the Fitbit Web API? I would appreciate any advice and recommendations!

Here are a couple of starts:

• https://github.com/Fitbit/sdk-oauth
• https://github.com/gondwanasoft/fitbit-rhr-fetcher

The first one will be closer to what you want, and much better written.
