Fragments 2017

A conference on the mobile ecosystem in India

#About Fragments:

Fragments is a two-day, single track conference on the mobile ecosystem in India. The conference will feature talks – full-length and crisp – panel discussions, and Off-The-Record (OTR) sessions.

We are looking for proposals in the following topics:

  1. Modern Development Practices

    • How are modern development teams structured?
    • How do you achieve cross platform design/feature parity?
    • How do your collaboration, decision making, and development processes adapt to accommodate cross platform teams?
  2. Continuous Integration/Continuous Delivery

    • How is your CI/CD pipeline designed to allow you to test, build and deploy to multiple platforms (Android,iOS,Web) simultaneously?
  3. Design

    • What tools and processes to designers follow when they have to design for multiple platforms simultaneously, given that each platform as it’s own guidelines/styles?
  4. Localisation and Accessibility

    • How do you handle localization and accessibility in modern mobile apps?
  5. Progressive Web Apps

    • Are progressive web apps the way forward?
    • Are progressive web apps a better way to solve cross platform development? What’s their future?
  6. On the ground case studies

    • Talks on how companies have changed their development workflows, processes, teams, app architecture, and tooling over time.
  7. Platform specific talks

    • We are also open to platform specific technology talks that are novel in their content or approach.

Commitment to open source

HasGeek believes in open source as the binding force of our community. If you are describing a codebase for developers to work with, we’d like for it to be available under a permissive open source licence. If your software is commercially licensed or available under a combination of commercial and restrictive open source licences (such as the various forms of the GPL), please consider picking up a sponsorship. We recognise that there are valid reasons for commercial licensing, but ask that you support us in return for giving you an audience. Your session will be marked on the schedule as a “sponsored session”.

Selection process

Proposals will be filtered and shortlisted by an Editorial Panel.

** Make sure to add links to videos / slide decks when submitting proposals. We will not review proposals without detailed outlines or slide decks and preview videos.**

The first filter for every proposal is whether the technology or solution you are referring to is open source or not. If you are referring to a proprietary technology, consider picking up a sponsored session.

The criteria for selecting proposals, in the order of importance, are:

  1. Key insight or takeaway: what can you share with participants that will help them in their work and in thinking about the problem?
  2. Structure of the talk and flow of content: a detailed outline helps us understand the focus of the talk, and the clarity of your thought process.
  3. Ability to communicate succinctly, and how you engage with the audience. You must submit link to a two-minute preview video explaining what your talk is about, and what is the key takeaway for the audience.

No one submits the perfect proposal in the first instance. We therefore encourage you to:

  1. Submit your proposal early so that we have more time to iterate if the proposal has potential.
  2. Talk to us on our community Slack channel: if you want to discuss an idea for your proposal, and need help / advice on how to structure it.

Our editorial team also helps potential speakers in honing their speaking skills, and rehearsing at least twice - before the main conference - to sharpen the focus of talks.

Passes and honararium for selected speakers:

A speaker is NOT confirmed a slot unless we explicitly mention so in an email or over any other medium of communication.

Selected speakers get a pass to the conference and networking dinner. We do not provide free passes for speakers’ colleagues and spouses.

We also pay an honararium of Rs. 5,000 to each speaker, at the end of their talk.

Travel grants for outstation speakers:

Fragments 2017 is funded through ticket purchases and sponsorships.
We try to provide full or partial travel grants for at least two international and two domestic speakers.
First preference in awarding grants is given to women speakers, persons of non-binary genders, and speakers from Africa. If you require a travel grant, indicate this in the field where you add your location.

Important dates:

Deadline for submitting proposals: 30 July, 2017

**Conference date: ** 12-13 Sept, 2017

Everything about Android Animations you were too afraid to ask

Submitted Jul 2, 2017

Animations in Android can be daunting with multiple moving parts and multiple ways of achieving similar results. From experience I have seen people just copying animation code from StackOverflow without really understanding how it all works. Understanding how the animation system works and what its limitations are is important to figuring out how and what you should animate in your app.

You’ll leave this talk having gotten a clear functional overview of everything about animations in Android including the newest Physics based Animation support library.


We will cover -

  • View Animations (the oldest animation system in Android. Only allows you to animate views and the following properties - position, size, rotation, and transparency)
  • Property Animations (Was introduced in Gingerbread. Allows you to animate objects other than views and also allows you to animate background colors)
  • Drawable Animations (allows you to animate Drawables by creating a film roll effect where you split an animation into multiple drawables and show them one after the other)
  • Transitions Framework
  • Animation Sets

All of the above topics come under time based animation systems which means that you have to specify the time for which you want the animation to run.

The Android UI Toolkit team recently introduced Physics based animations where you don’t have to provide total time required for an animation. Instead you specify source, destination and velocity. This allows a bunch of new possibilities which we will cover. For instance if the destination of your view moves then the animation doesn’t abruptly stop after its time ends but continues until the destination is reached.

  • Physics Based Animations
    • Dynamic Animation
    • Spring Animation
    • Spring Force
    • Fling Animation

This talk will be code heavy and gif heavy. We will go over sample code and demonstrate its effects.

Speaker bio

I have been working on Android apps for the past 3 years. I work with Android, Python and Javascript at as a software developer. You might know me from other events like Pycon 2014 in Montreal where I presented a poster on Creating a Fall Detector using Raspberry Pi and Python or from my talk at Droidcon 2016, Bangalore on Jack & Jill or from my indie app Search for Reddit.
