Migrate examples from `MapboxNavigationProvider` to `MapboxNavigationApp`

It will be some time before we upgrade the examples repository to com.mapbox.navigation:android:2.8.0-alpha.2.

Opening so we can start considering the migration, but we're still building tools that make migration easier
For example the extensions are still experimental.

• ShowAlternativeRoutesActivity
• ShowManeuversActivity
• MultipleWayPointsActivity
• ShowTripProgressActivity
• ShowCameraTransitionsActivity
• ShowCurrentLocationActivity
• ShowJunctionsActivity
• FetchARouteActivity
• RenderRouteLineActivity
• TurnByTurnExperienceActivity
• MapboxSignboardActivity
• PlayVoiceInstructionsActivity
• ShowSpeedLimitActivity
• ReplayHistoryActivity
• CustomArrivalActivity
• ShowBuildingExtrusionsActivity

Migration plan

We want to commit to a migration plan for the examples repository by September 5th because that is the week the 2.8.0 release becomes a release candidate and we will be committed to apis for a stable release.

Note that, not-migrating and using MapboxNavigation directly is also an option. MapboxNavigationApp is built for large apps.

Resources

The architecture is designed for you to build de-coupled classes like the LocationComponent, or a more complicated example is the CameraComponent. There are other approaches that are worth considering.

Some public documentation on the MapboxNavigationApp can be found here https://docs.mapbox.com/android/navigation/guides/androidauto/car-app-lifecycle/

We will also explore migration ideas in the qa-test-app

Ideas are welcome

I'm obviously not the only one using this new library, so feel free to bring in some opinions and ideas. Feel free to open a pull request against this migrate-MapboxNavigationApp branch. Or create new pull requests.

Start with the migration plan and the listed example activities, then review the MapboxNavigationApp documentation and the qa-test-app for migration patterns. The migrate-MapboxNavigationApp branch and the linked architecture resources provide additional context. Done means either migrating the listed examples consistently or documenting a decision to continue using MapboxNavigation directly.
