FlickrIt

FlickrIt lets you search images from Flickr API. It uses the Flickr API key.

How FlickrIt search works?

• By default the app loads search results for the query "kittens".
• To search, you can use the SearchView inside the Toolbar on the top right corner.
• The app also lets you scroll endlessly.
• The user can pull to refresh to reset/restart search.

Architecture

FlickrIt is built on top of MVP architecture:

• The searching feature is fulfilled by a SearchContract.
• The SearchInteractor gets the photo results from the Flickr API via the FlickrApiClient. It contains the SearchModel which is the single source of truth of the app. The interactor publishes this model to the presenter.
• The SearchPresenter talks to the SearchInteractor. It renders the SearchState (aka SearchViewModel) on the SearchView whenever the interactor publishes it.
• The SearchView renders the SearchState onto the SearchFragment and also posts actions to the SearchPresenter.

Injections

• FlickrApiClient lets you use the Flickr search command and returns a NetworkResults<SearchResponse>.
• ApiClient is a wrapper on top of OkHttpClient which lets you make synchronous/asynchronous requests.
• ImageService lets you download images from network.
• SearchMapper and PhotoMapper helps transforming the network entities into DTOs.

Unit Tests

• Unit tests can be found under test package.

Image Caching

• ImageFetcher helps fetch image Bitmap from Memory, Disk or Network (whichever is available first).
