Answer 1

The answer that is marked correct is not a 100% correct. I think that can still fail in cases where the map never loads due to connectivity, or if the map gets updated so quickly that it never fully finishes loading. I have used the addOnGlobalLayoutListener.

ConstraintLayout mapLayout = (ConstraintLayout)findViewById(R.id.activityLayout);
mapLayout.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener()
{
    @Override
    public void onGlobalLayout()
    {
         //Your map code
    }
});
