Using Git Like a Pro and Moving Onto Clean Architecture

Thursday, 15th December at CodeNode, London

This meetup was organised by Londroid: The London Android User Group in December 2016

Interested in using Git like pro? Want to move on from legacy code to clean architecture? Join Londroid to learn “Master-only” workflow, other branching strategies and Git hacks with Lead Android Developer at ASOS, Savvas Dalkitsis, and how clean architecture is utilised to create a lasting app at Buffer with Buffer's own Android Engineers, Joe Birch and Marcus Wermuth!

Using Git like a pro: “Master-only” workflow, other branching strategies and Git hacks

In this talk we will be discussing advanced Git techniques, how you can utilize different branching strategies to achieve a rapid workflow depending on the structure of your team, followed by an assortment of 'hacks', or useful tricks, that allow you to optimize the way you work and share code with others.

On the journey from legacy code to clean architecture

Buffer for Android was first made in 2012 - and since then it's seen a range of iterations and features. Whilst it's important for a product to grow in-order to meet the needs of users, it's easy for code to become unclean and lose any sense of architecture. This legacy code makes it difficult for us to maintain our product and build new features without the fear of breaking the app.

But there is light! At Buffer we've just started to re-architect and refactor our application for Android using a clean architecture approach. Re-crafting our application feature by feature with the help of RxJava, Dagger and tests in the form of jUnit and Espresso has begun to result in a more stable, better architected and maintainable codebase. Together with our new continuous Integration flow this all helps in providing a better Buffer experience on Android.

In this talk we will explore the journey we took through refactoring from legacy code to a clean architecture. Starting with heart of our app, the Composer, we'll share our learnings and findings discovered on our journey and the benefits from doing so.

The talk will consist of several sections to demonstrate our learnings. We'll be looking at:

  • The original state of the app . Here we'll look at the original architecture and state of the Android Application, the hurdles it created for us and the reasons why we decided it was time for change

  • Adding CI to the mix. We will go into our CI structure and how everything is setup and helps us keeping a reliable building and testing environment.

  • Rebuilding with a clean architecture . In this section of the talk we'll look at beggining of the rebuild journey, starting with the composer. Here we'll look at the transofrmation of the codebase and architecture of the app, applying SOLID principles and how we're creating a more maintainable and extensible codebase

  • Rebuilding with a clean architecture . In this section of the talk we'll look at beggining of the rebuild journey, starting with the composer. Here we'll look at the transofrmation of the codebase and architecture of the app, applying SOLID principles and how we're creating a more maintainable and extensible codebase

  • A summary of our learnings . Finally, we'll look at the overall impact these changes have had on the android app as a whole, the increase in code quality and what this holds in place for the future of our app - allowing the listeners to take away some influence to achieve similar implementations.
