License API Build Status License

👑 The GoldMovies is based on Kotlin, MVVM architecture, coroutines, dagger, koin, and material designs & animations.


What Open API Used?

The Movies Database (TMDB) is a community built movie and TV database. Every piece of data has been added by our amazing community dating back to 2008. TMDb's strong international focus and breadth of data is largely unmatched and something we're incredibly proud of. Put simply, we live and breathe community and that's precisely what makes us different.

How to build on your environment

Add your The Movie DB's API key in your file.


Module structure

The module structure is designed to try several different architectures.

Entity module

Entity module composed of entity models for persisting in database and response models for fetching data from network requests.


  • Room Persistence - constructing database (An abstraction layer over SQLite).
  • Gson converter - a converter which uses Gson for serialization to and from JSON.
  • Threetenabp - an adaptation of the JSR-310 backport for Android.

Unit Test

Unit Tests to construct database and migration to newer versions using the Room.

Network module

Network module composed of abstractions for RESTful requests. And ApiResponseModel for standardizing a raw request model. An Interceptor for requesting every time with a query parameter api_key.


Unit Test

Unit Tests to verify RESTful requests abstractions via a testing web server and mocked data.

Common-ui module

Common-ui module composed of adapters and viewholders for composing recyclerview's item via databinding. And some factories and extensions related to custom views.


  • Google-Material - material Components for Android (MDC-Android) help developers execute Material Design.
  • Glide - loading image.
  • GlidePalette - compatible with glide, extracting a primary color from an image.
  • BaseRecyclerViewAdapter - fast way to binding RecyclerView adapter and ViewHolder for implementing clean sections.
  • WhatIf - fluent Kotlin expressions for a single if-else statement, nullable and boolean.
  • Flourish - a polished and dynamic way to show up layouts.
  • AndroidRibbon - beautiful and the simplest ribbon view with shimmering effect.
  • ExpandableTextView - allows developers to easily create an TextView which can expand/collapse.

Mvvm module

Mvvm module is the implementation of user interfaces on the application. Based on mvvm architecture (view-databinding-viewmodel-model) with the repository pattern.

  • JetPack
    • LiveData - notify domain layer data to views.
    • Lifecycle - dispose observing data when lifecycle state changes.
    • ViewModel - UI related data holder, lifecycle aware.
    • Room Persistence - construct database.
  • Dagger2 - constructing dependency injection framework based on compile-time.
  • Timber - this is a logger with a small, extensible API.

Unit Test

Unit Tests verify the interactions of viewmodels between repositories and dao & REST api requests.

Mvvm-coroutines module

Mvvm-coroutines module almost same as the Mvvm module. Implementation of user interfaces on the application. Based on mvvm architecture and coroutines.

  • Coroutines - kotlin side(at the language level) supports for asynchronous programming.
  • Koin - A pragmatic lightweight dependency injection, actually service locator.
  • Timber - this is a logger with a small, extensible API.

Unit Test

Unit Tests verify the interactions of viewmodels between repositories and DAO & REST api requests.

Unit Testing Frameworks

  • Robolectric - Robolectric is the industry-standard unit testing framework for Android.
  • Mockito-Kotlin - a small library that provides helper functions to work with Mockito in Kotlin.

User Interface Design

Based on Material design & animations.

  • Google Material Design.
  • Ripple Effect.
  • Shared Element Transition.
