@gpeal when you get a chance, can you review this? |

Can you move setting paused to true and false into onPause and onResume? The boolean logic being here breaks now that you call onPause separately.

How would destroy get called without pause?

You can just set destroyed to true at the top of the method. This will prevent future logic errors if you ever return early or anything

You can also start the method with:
if (destroyed) {
return;
}
destroyed = true;
| } | ||
| if (!destroyed) { | ||
| onDestroy(); | ||
| destroyed = true; |

What happens if this gets called while the map is initializing before onMapReady is called? Can you cancel the initialization? Maybe return early from onMapReady if destroyed?

Hi @lelandrichardson, thanks. @gpeal 's comments make sense to me (but I haven't got a chance to change :( ). If your followup PR contains some changes requiring some real case testing, please let me know, I will apply it to our app and let the testers have a try. |
