MapBox SDK black screen on resume

Question

I am using MapBox SDK on my android application, the map onCreate appears perfectly. I can add layers and show my markers and so on.
When the user clicks on a marker another activity is started. So I use mapView.onPause() on my onPause() method.
The issue appears when the user tries to go back to the map activity, I am using finish() method for that and once on the map activity a black screen replaces the map and the user can no more see the map and markers.
I figured out that the issue appears also when I lock the phone and come back to the application.
Any ideas about how to resolve that.

thank you very much.

Are you calling all of the required lifecycle methods? Here's the list: mapView.onCreate(savedInstanceState); mapView.onStart(); mapView.onResume(); mapView.onPause(); mapView.onStop(); mapView.onLowMemory(); mapView.onDestroy(); mapView.onSaveInstanceState(outState); — Łukasz Paczos, Mar 04 '19 at 17:07
I checked out the MapBox onResume to see what it does, I found that it calls mapRenderer.onResume() and this method is not implemented :/ — Abderrahmane Kaci Aissa, Mar 05 '19 at 09:12

Forgot to override onStart() method in my activity. I had to add it, and then the problem was solved.

Edit:

Link to the Mapbox LifeCycle Methods.

Added code-snippet for onStart():

    @Override
    public void onStart() {
        super.onStart();
        mapView.onStart();
    }

I have added this in my fragment but its not working.In logcat it caught an exception java.lang.Exception: Last location unavailable – Abraham Mathew Jun 02 '20 at 10:51
try to open GoogleMaps and locate yourself, then retry it with your application. – Abderrahmane Kaci Aissa Jun 02 '20 at 13:20
Last location is often saved when we use maps application – Abderrahmane Kaci Aissa Jun 02 '20 at 13:21
Why is this like this.In some devices its ok but in some others its not ok.How can we handle the situation – Abraham Mathew Jun 02 '20 at 13:45
actually, I think your not looking for the current location or your device is not able to find the current location, it's either your gps is off or you have no GPS signal,so it tries to restore the last location stored in your device. as you didn't have any last location (especially when you test with a virtual device) the application cant find a reference location – Abderrahmane Kaci Aissa Jun 02 '20 at 14:28
I am running on real device.Yes in my case gps is disbaled. – Abraham Mathew Jun 02 '20 at 14:48
