Background
Plaid was written with one big goal: showcase material design in Android in a real application. While Plaid successfully achieved its goal, from an architecture point of view, it lacks all features that would make it a modular, scalable, testable and maintainable app: with UI logic in Android classes, no tests and only one module.
Plaid represents a great real world app example: it provides a fairly complex set of functionalities, it has technical debt, it has features that have to be dealt with as APIs are being removed.
All of these problems are encountered by many projects in the Android community and therefore, make Plaid a suitable showcase for all the advantages that architecture components bring.

Goals
- Migrate Plaid to Architecture Components. The refactoring will follow the architecture described in Guide to App Architecture.
- Convert to Kotlin, while migrating to Architecture Components.
- Modularize the app using dynamic feature modules.
- Showcase the extensibility of the architecture by adding an extra data source, once the migration is finished.
Non-Goals
Changes to the styles, themes, icons, animations, transitions or any other UI elements that were the initial focus of Plaid, are outside the scope of this refactoring.
Android Studio IDE setup
Plaid requires Android Studio version 3.4 or higher.
Plaid uses ktlint to enforce Kotlin coding styles.
Hereβs how to configure it for use with Android Studio (instructions adapted
from the ktlint README):
- Close Android Studio if itβs open
-
Download ktlint using these installation instructions
-
Inside the project root directory run:
./ktlint --apply-to-idea-project --android
-
Remove ktlint if desired:
rm ktlint
- Start Android Studio
Plaid 1.0
Design news and inspiration.
Plaid is a showcase of material design that we hope you will
keep installed. It pulls in news & inspiration from Designer News,
Dribbble & Product Hunt. It demonstrates
the use of
material principles
to create tactile, bold, understandable UIs.
Install on Google Play (Beta Testing)

Non-Goals
Plaid is a UI sample and seeks to demonstrate how to implement material design. To make this as clear as possible it explicitly does not attempt to:
- Provide opinionated architecture/testing advice; it utilizes vanilla Android components. For advice on this, Iβd recommend Blueprints.
- Support pre-Lollipop devices. Doing so is entirely possible, but complicates things. For advice on doing this, see this fork.
