Best To Do App is a sample project that presents modern, 2021 approach to Android application development using Kotlin and latest tech-stack.
The goal of the project is to demonstrate best practices, provide a set of guidelines, and present modern Android application architecture that is modular, scalable, and maintainable. This application may look simple, but it has all of these small details that will set the rock-solid foundation of the larger app suitable for bigger teams and long application lifecycle management.
First off, you require the latest Android Studio 4.1.0 (or newer) to be able to build the app.
In terms of design has been followed recommendations android material design comprehensive guide for visual, motion, and interaction design across platforms and devices. Granting the project in this way a great user experience (UX) and user interface (UI). For more info about UX best practices visit link.
Moreover, has been implemented support for dark theme with the following benefits:
- Can reduce power usage by a significant amount (depending on the device’s screen technology).
- Improves visibility for users with low vision and those who are sensitive to bright light.
- Makes it easier for anyone to use a device in a low-light environment.
| Mode | List Fragment | Update Fragment | Add Fragment |
|---|---|---|---|
| Light |  |
 |
 |
| Dark |  |
 |

The architecture of the application is based, apply and strictly complies with each of the following 5 points:
- A single-activity architecture, using the Navigation component to manage fragment operations.
- Android architecture components, part of Android Jetpack for give to project a robust design, testable and maintainable.
- Pattern Model-View-ViewModel (MVVM) facilitating a separation of development of the graphical user interface.
- S.O.L.I.D design principles intended to make software designs more understandable, flexible and maintainable.
- Modular app architecture allows to be developed features in isolation, independently from other features.
The documentation is generated following KDoc language (the equivalent of Java's JavaDoc) via documentation engine for Kotlin Dokka.

This project takes advantage of many popular libraries, plugins and tools of the Android ecosystem. Most of the libraries are in the stable version, unless there is a good reason to use non-stable dependency.
- Jetpack:
- Android KTX - provide concise, idiomatic Kotlin to Jetpack and Android platform APIs.
- AndroidX - major improvement to the original Android Support Library, which is no longer maintained.
- Data Binding - allows you to bind UI components in your layouts to data sources in your app using a declarative format rather than programmatically.
- Lifecycle - perform actions in response to a change in the lifecycle status of another component, such as activities and fragments.
- LiveData - lifecycle-aware, meaning it respects the lifecycle of other app components, such as activities, fragments, or services.
- Navigation - helps you implement navigation, from simple button clicks to more complex patterns, such as app bars and the navigation drawer.
- Room - persistence library provides an abstraction layer over SQLite to allow for more robust database access while harnessing the full power of SQLite.
- ViewModel - designed to store and manage UI-related data in a lifecycle conscious way. The ViewModel class allows data to survive configuration changes such as screen rotations.
- Coroutines - managing background threads with simplified code and reducing needs for callbacks.
- Recycler View Animations - Manage the recycler view custom animations
- AestheticDialogs - Manage the custom dialogs of the app
Avoid reinventing the wheel by following these guidelines:
Google Developers Codelabs provide a guided, tutorial, hands-on coding experience. Most codelabs will step you through the process of building a small application, or adding a new feature to an existing application. They cover a wide range of android concepts to learn and practice:
