I dont find any relevant information how to start my project, so I try it there.
My project will be app that check your health data and if some data will be out of range, this app send notificiation via sms / e-mail. For example, if your BPM will be under 40 - send notification, if you take off watch - send sms, if you dont move above 15 min - send sms and so on.
Now the conditions:
1 - this is private app - not for public (so no need to put this app to Google Play)
2 - I need update this app remotely (maybe samsung knox…?)
I will be very thankfull for any advice.
