     // Show user location (purposely not in follow mode) 
     mapView.setMyLocationEnabled(true);

Quando si utilizza lo stesso layout all'interno della attività si sta lavorando.

Ho avuto questo problema esatto quando ho aggiornato il mio Mapbox SDK per Android. L'ho risolto aggiungendo mapView.onCreate(savedInstanceState) dopo aver inizializzato lo MapView. Spero che questo ti aiuti.
