Fill widget with Firebase

Question

My application uses the Firebase database, and the elements display correctly in RecyclerView, but I want to display them also in widgets. Since the widget is not an activity, I run into all the problems using Firebase and ListView. Is there a way to populate a widget from Firebase?

Answer 1

For more than 20 seconds, onDataSetChanged () to retrieve data from the Internet / Firebase database does not display data as a list of widgets. You will need to use CountDownLatch.
