mapbox through exception Fatal Signal 11
I have a fragment which contain MapView. On first time the MapView loads and every things is perfectly good but when i go to next fragment and then comeback to my oldFragment the code certainly through an exception libc: Fatal Signal 11 i am using version 6.7.0 and using locationComponent api
Can some one please suggest me some things

In a fragment you have to call the lifecycle methods in onCreateView() and in onDestroyView(). See https://github.com/mapbox/mapbox-gl-native/blob/master/platform/android/MapboxGLAndroidSDK/src/main/java/com/mapbox/mapboxsdk/maps/MapFragment.java

Thanks for reaching out @nouman1nv, and thanks for jumping in @arnekaiser! And to confirm - yes, you need to call MapView#onCreate from fragment's onCreateView() and MapView#onDestroy from fragment's onDestroyView().

thank you very much @LukasPaczos and @arnekaiser
i have one another issue i am displaying mapbox in recyclevie which through an exception
A/libc: Fatal signal 6 (SIGABRT), code -6 in tid 5230 (FinalizerDaemon)
how to manage lifecycle in recycleview

[LukasPaczos]

A general rule is that you need to follow the view lifecycle inside of the recycler rather than activity/fragment's lifecycle when calling MapView's lifecycle methods. So, whenever a view is recycled, you need to call onPause, onStop and onDestroy. Then, reverse the process for when the view is created.

You can also check out the POC in mapbox/mapbox-gl-native#13132.

Closing as not-actionable from plugins perspective.
