Connect Android Phone With Forerunner 55 Via Ant+

Hi!

I am trying to develop an app on my Android phone with Android Studio, which could get all the data from my live running activity from Forerunner 55. I have found out that there are ant+ sensors and that my Samsung Galaxy S8 is compatible with it and also my Forerunner 55. I am wondering, if I can develop an App in Android Studio, which could get all the running data mid-activity from my Forerunner 55. Also, if there are any apps out there, which already do that for me, i would love to know more about that also.

Any info would mean a lot to me!
