How to work from a widget with standard data sources?

Question

Android

Good day!
There is a task of developing a widget for Android that would display information about recent calls. It is not clear how to work with data sources like ContactsContract or Call Log in the widget? getContentResolver() on the widget doesn't work.
This is not written in any literature (at least I did not find it).

Answer 1

When working with a widget, all data must be processed in the service. getContentResolver is a Context method. Well, that's what you mean.
