Accessing device sensors and some random question

I tried to follow the amazing work described here Getting Started: Android Development References - Documentation Feedback - Feedback for Unreal Engine team - Unreal Engine Forums but is pretty an hard job.
My first question is:

  • is there any way to get data from sensors (or basically doing generic android apis requests) just like the pedometer or the heart rate (not available to all devices, i know) without engine customization?
  • let’s say i want to show an activity, can i do that via c++ or blueprint as before, without engine customization? Do i have to design such activity programmatically or can i use xml in some way?
