IllegalStateException map size should not be 0 [duplicate]

Question

I have a MapFragment that displays a map

if the user goes away from the activity (or the device goes to sleep) with the map then comes back onResume gets called and I move the map back to a marker.

however when I move the camera I get an exception

This is my camera movement on my onResume

if(map != null && northEast != null && southWest != null){
        map.animateCamera(CameraUpdateFactory.newLatLngBounds(new LatLngBounds(southWest,northEast),10));
    }else if(map != null && centerPoint != null){
        CameraPosition position = new CameraPosition.Builder()
         .target(centerPoint).zoom(17).build();
        map.animateCamera(CameraUpdateFactory.newCameraPosition(position));
    }

If I take out the camera movement it does not crash but does not go back to the point of they moved away from it or something.

I check to make sure the map is not null so I do not know what is causing the error?

Answer 1

Caused by: java.lang.IllegalStateException: Map size should not be 0. Most likely, layout has not yet occured for the map view.

This should be clear enough. You cannot call

map.animateCamera(CameraUpdateFactory.newLatLngBounds(new LatLngBounds(southWest,northEast),10));

before the layout is complete. You need to use 3 param version instead.

See the documentation here: newLatLngBounds

Aternatively you may listen for the layout to complete instead of calling this code in onResume.
