Fragments 2019

Fragments 2019

State of mobile engineering, state of platforms, hardware and user research.

What you can expect from the Bangalore edition of Fragments on 30 March:

Fragments was launched in response to the fragmented nature of engineering and software development for mobile. Much changed for mobile engineering in 2017 when React Native entered the landscape and cross-platform mobile development took off in a big way.

At the recently concluded ReactFoo, we talked not only about the ecosystem emerging with ReactFoo, but also how organizations are structuring teams for Android, iOS and cross-platform mobile development.

Coming back to Fragments, the Android versus iOS debate seems to be settled with Android winning the turf. Now, with Flutter taking off as a platform for mobile engineering, the battleground has opened between React Native versus Flutter. Who will win is not only a matter of adoption and user base metrics, but also which platform has a stronger community around it.
On 30 March, speakers Priyanka Sabhagani and Ajin Asokan will share BookMyShow’s and Zerodha’s experiences (respectively) with React Native and Flutter, helping participants evaluate each platform’s strength and weaknesses. We look forward to deeper discussions around Flutter, where the platform has piqued a great deal of interest from developers (who have to write less code), but greater skepticism about Flutter’s capabilities with respect to data storage and related issues from senior developers.

Apart from Flutter, the Bangalore edition of Fragments will feature talks on Kotlin and native app development. An interesting question to discuss here is the decision to go native versus when not to go native with your app. Which factors inform such a decision?
The other discussion which Raghunath Jawahar, Varsha Saha and Abhinav Rastogi will take up is what native app developers can learn from the mature web front-end architectures. The discussion will steer around the following topics:

  1. The dynamic nature of JavaScript versus static languages like Java/Kotlin/Swift which is used to develop native mobile apps.
  2. Expectations and user experience on web versus mobile.
  3. The asynchronous nature of mobile platforms and their lifecycles – the unique challenges this factor presents.

Finally, Fragments Bangalore will showcase talks on:

  1. Image uploads and Contraint and Motion layout.
  2. Optimizing the size of your mobile app.
  3. Voice, and its role in building augmented experiences for mobile apps.
  4. How the concept of Seams can be applied for building flexible and testable apps.
  5. Building predictable and high performance workflows for mobile app engineering.

Performant and Reflection-Less JSON Parsing using STAG

Submitted Mar 14, 2018

How to improve the performance of JSON parsing in Android, and why STAG ?

This talk will cover the internal working of the infamous GSON library, and the performance bottlenecks that we hit, and how to take a Reflection-Less approach for the same.

Outline

  • How GSON serializes/deserailizes objects ?
  • Why is Reflection Expensive ?
  • Performance Issues with Current Implementation
  • What is TypeAdapter, and why to use it ?
  • Introduction to STAG
  • STAG in Parity with GSON

Speaker bio

While working on the performance aspects of parsing, we came across a library STAG. The overall idea of the library was good, and with initial testing we found a good boost in parsing performance. We added a bunch of features, and contributed back to the open source community. Now, STAG is in parity with GSON, and we had ~20% improvement in parsing time, and cold boot time.
