I've started using Dagger2 to manage dependencies and I'm trying to understand how I can use DI to provide a singleton GoogleApiClient. The motivations for this are:
- reduce boilerplate code: multiple Activities & Fragments require a GoogleApiClient
- improve testability: currently these Activities and Fragments are not well tested
I want to provide a Singleton GoogleApiClient at the Application scope.
How do you handle callbacks? Whether you choose an auto-managed or manually-managed connection, there are some callbacks that must be handled:
- GoogleApiClient.ConnectionCallbacks (manual only)
- GoogleApiClient.OnConnectionFailedListener (both)
