使用Google Fit API可以安装和不安装Fit App，也可以离线工作

Question

I am trying to develop an application that can count steps. I am using Xamarin.Forms, so I will have to make the Android part and the iOS part.

In the Android, I want to use Google Fit API's. I already implemented History API, to get the last week buckets of steps, and it is working. But this only works if the Google Fit App is installed. But I want to have an application that is independent of Google Fit App. So, I think I need to use the Google Fit Record API or Google Fit Sensors API. I think the Record API is automatically saving the sensor data to the History API database. However, to do this I will need Network access, right? If yes, I would like to use it when a network is available (and GoogleFit app is not installed). But when it is not available maybe the Sensors API is the right answer. Using Sensors API, should I create a Background Service (working even if the app is closed) that receive sensor data and periodically save data to a SQLite database (I already have this DB implemented)?

Am I dificulting this a lot and I just need to use one API for everything? I want Google Fit API because I would like to append wearables to the account when possible.

I really need help to understand what it is possible or not, please.

Thanks in advance!
