Crash in LeanbackShowcase LiveDataRowsActivity

Dependency injection needs to be fixed for the Activity and Fragment, but the version of Dagger is also very old, so we need to investigate whether it makes sense to update to a newer version or move away from dependency injection.

Start with LiveDataRowsActivity.onCreate at line 52 and the reported No injector factory bound error, then inspect the related Activity and Fragment injection setup and the project's Dagger version. Reproduce the LeanbackShowcase crash and determine whether updating Dagger or changing the dependency-injection approach is appropriate; done means the Activity and Fragment launch without this exception.
