So originally my app would crash when I pressed the back button to return to the SpudMapFragment. Then i added the onDestroy() in the fragment however now i have a new weird crash with the same error msg. Now it crashes if i go to another fragment, return to SpudMapFragment, go to another fragment, then return to SpudMapFragment. Pretty much if i return to SpudMapFragment on th 3rd time it will crash.
This next section is a tldr of what the app looks like When the app opens, the SpudMapFragment is shown right away, if you swipe open the navigation drawer then a list of items show up, only two of them have fragments, this would be the Maps and Buy options. Clicking on maps will reload the maps fragment.
The error message: android.view.InflateException: Binary XML file line #2: Binary XML file line #2: Error inflating class fragment
The error points to "return inflater.inflate(R.layout.maps_fragment, container, false);" in SpudMapFragment.

Ive seen other errors similar to this but i have tried changing everything and nothing has worked, right now im working on the fragment life cycle since i think it has to do with that but im still only 1 month old in android. Any help would be super awesome, thank you. Ill reply rapidly to any responses if there are any questions or if it worked or did not work or if i tried it already.
edit 1: added stacktrace/logcat
