How to call an Activity's non-static method from inside a service onStart()?

You can't.

However, there are many ways to have a service communicate with a running activity, and I outline some of them here: How can I update information in an Android Activity from a background Service

This could help ..

In activity define

static MyActivity instance; 

then set value MyActivity.OnCreate

instance = this; 

In your service

MyActivity activity = MyActivity.instance;          if (activity != null) {             // we are calling here activity's method          }
