Answer 1

Seems you got custom constructor in your FragmentDetailsVehicle class, but then you also need default one added by hand, even if it does nothing really:

public FragmentDetailsVehicle() {}

See: https://developer.android.com/reference/android/app/Fragment.html

All subclasses of Fragment must include a public no-argument constructor. The framework will often re-instantiate a fragment class when needed, in particular during state restore, and needs to be able to find this constructor to instantiate it. If the no-argument constructor is not available, a runtime exception will occur in some cases during state restore.
