This repository contains Giphy GIF browser Android application which is done as Mobimeo Android Interview Challenge.

The app is composed of 2 screens:

It allows you to search for GIFs. Network results are kept in being loaded on UI. It supports pagination and loads more when the user scrolls down.

It previews the selected GIF in fullscreen.

You can clone and open the project in Android studio and press run!

The project uses local unit tests that run on your computer. To run those tests and generate a coverage report, you can run:

./gradlew jacocoReport

NOTE: You can find the tests report in app/build/reports/jacoco/jacocoReport/html/index.html

The Application implemented and structured based on Clean Architecture and SOLID principles best practices and the presentation layer is implemented based on the MVP pattern.

The Data layer contains Network Client implemented by Retrofit library to get access to remote data on GIPHY API. It also uses Retrofit caching feature to save some results to load in case of no internet connection.

The Domain layer consists of a Repository that allows access to the Data layer. It also uses Kotlin Coroutines IO and Main dispatchers to execute long-running tasks in the background and reflect the result on UI. There is also a Test dispatcher that executes tasks immediately on the same unit test thread.

The View layer is done with two Activities and multiple Fragments which uses the main contract interfaces for implementing the view and presenter to respond to user interactions.

The Koin library does the dependency injections in the whole app.

GitHub Actions CI service is running the repo tests and build Gradle tasks and jacoco plugin generates and submit the code coverage reports to codecov.io.

There are some unit tests using Mockito and Kluent and some Android tests using Robolectric.
