Crash: Attempt to invoke virtual method 'void com.mapbox.navigation.ui.MultiOnClickListener.clearListeners()' on a null object reference

Chưa có ai nhận issue này.

**Android API:**
Mapbox Navigation SDK version: **9.6.0** and Navigator **1.1.0** & **1.3.0**

### Steps to trigger behavior

1. Basically I'm using the sample from here https://docs.mapbox.com/android/navigation/guides/install/ (however it is converted into a different language).
2. Pause/Switch Application

### Expected behavior
No Crash

### Actual behavior
Crash

Appears to be like #1971, however the stack trace appears to be slightly different.

This occurs when I click the `Switch` application button (i.e. Square Nav Button); the app throws this error. I am logging all the events; and I see:
The Pause & Stop events in sequence, which I then chain to the MapBox Navigator onPause, onStop calls exactly like the demo. However about 1/2 a second after; I get the below stack trace crash.... I've also tried not sending the onStop, onPause, etc... No change...

Based on the callstack below; I suspect the issue is something has already called:
https://github.com/mapbox/mapbox-navigation-android/blob/master/libnavigation-ui/src/main/java/com/mapbox/navigation/ui/RecenterButton.java#L142-L146

And
https://github.com/mapbox/mapbox-navigation-android/blob/master/libnavigation-ui/src/main/java/com/mapbox/navigation/ui/RecenterButton.java#L144
This line I believe is actually invalid, as nothing in the code will re-create the MultiOnClickListener again in this element.
as it is only created during creation of it, so if this element is re-attached it will misbehave and crash later:
https://github.com/mapbox/mapbox-navigation-android/blob/master/libnavigation-ui/src/main/java/com/mapbox/navigation/ui/RecenterButton.java#L29

According to https://stackoverflow.com/a/65227045 & https://proandroiddev.com/make-your-custom-view-lifecycle-aware-its-a-piece-of-cake-90b7c0498686 it appears `onDetachFromWindow` is NOT the place to cleanup/null things like this, as the view can be re-attached **without** being re-created if used in things like tabs/pagers. So nulling the listener will lead to a crash if it is re-attached. In addition it might be good if you checked to verify that the `MultiOnClickListener` isn't null in the `clearListeners` function on line 143 as something obviously called this function a second time...

Bắt đầu với libnavigation-ui/src/main/java/com/mapbox/navigation/ui/RecenterButton.java, đặc biệt là onDetachedFromWindow và clearListeners, rồi xem xét stack trace được cung cấp. Tái hiện sự cố bằng cách chuyển khỏi ứng dụng điều hướng mẫu, sau đó xác minh rằng việc tách và gắn lại view không còn gây ra sự cố do đối tượng null.
