Github Searcher

Summary

Android app capable of searching GitHub repositories by keywords as well as any qualifiers using the v4 GraphQL API.

Architecture

The application uses MVP Architecture together with dependency injection to provide the objects needed for each view/presenter dynamically. Also it applies the repository pattern to provide access to a cache of objects which are kept in sync with a local data storage and a remote data storage. The local data storage provides persistence when the app subsequently opens without internet.

The main repository list also has infinite scrolling capabilities requesting the github api more repositories based on the id of the last repository fetched.

Libraries/Dependencies

Dagger2 and Dagger-Android for dependency injection to achieve a decoupled more testable logic
Room for storing data locally creating redundancy on network failure
Retrofit2 for retrieving remote data
Retrofit2 converter-gson
okHttp Logging Interceptor for intercepting and logging all request and response made using retrofit for converting json to java classes automatically
Picasso for loading images efficiently into the views and some transformations
Android Debug DB for live browsing DB content and debugging issues related to local data storage
Mockito for mocking classes for unit testing

Pre-requisites / How to run
