MapView not redrawing when fragment gets replaced #191

Closed TostF closed 5 years ago

TostF commented 5 years ago

I've MapView in FragmentWithMap that is a part of ViewPager. When I replace FragmentWithViewPager that holds ViewPager with some other FragmentReplacer and return via PopBackstack my map does not get redrawn. Why is this happening?

I am triggering mapView.onPause() and mapView.onResume() in fragment lifecycle methods but it does not help. I've read that I should check if MapEngine is initialised and trigger onResume() only then but it did not help either.

What am I doing wrong?

I was looking for example of MapView being used in samples repository but all all of them includes MapFragment (which I would rather not use).

I would be great if you could provide a sample code of MapView implementation so I can check if I'm properly managing MapEngine.

This issue is fixed in 3.10 release which will be out soon, probably next week.

Is MapView example possible tough? I have major performance issues when adding another map instance on view stack.

I'm going to close the issue for now. Will re-open if new version isn't going to fix the issue.
