What's your thinking on Android this year?

About Droidcon

Droidcon is India’s largest Android developer conference, and is part of the world wide series of conferences that happens in London, Paris, Berlin, Netherlands, Tunis, Ankara and Brussels. If you are doing anything with Android, you’d want to be here in Bangalore on Nov 28-30th 2013.


A WIP schedule will be up on the Droidcon India website and will be updated periodically.

Selection Process

Voting is open to attendees who have purchased event tickets. If there is a proposal you find notable, please vote for it and leave a comment to initiate discussions. Your vote will be reflected immediately, but will be counted towards selections only if you hold a ticket. Proposals will also be evaluated by a program committee, consisting of:

Proposers must submit presentation drafts as part of the selection process to ensure that the talk is in line with the original proposal, and to help the program committee build a strong line-up for the event.


Final date for submission of proposals Oct 18th, 2013.

First set of pre-confirmations Oct 18th, 2013.

Submission of slide drafts Oct 25th, 2013.

Second set of pre-confirmations Oct 26th, 2013.

Schedule draft posted on site Nov 4th, 2013

Final confirmations Nov 5th, 2013.

Final schedule Nov 8th, 2013

All speakers are requested to be available for officehours during the conference. This will be a scheduled 30 minute block of time during which attendees can meet you at a designated space for open Q&A offstage.

There is only one speaker per session. Attendance is free for selected speakers. HasGeek will cover your travel to and accommodation in Bangalore from anywhere in the world for speakers delivering full sessions (30 minutes or longer). As our budget is limited, we will prefer speakers from locations closer home, but will do our best to cover for anyone exceptional. If you are able to raise support for your trip, we will count that as speaker travel sponsorship.

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 it to be available under a permissive open source license. If your software is commercially licensed or available under a combination of commercial and restrictive open source licenses (such as the various forms of the GPL), please consider picking up a sponsorship. We recognize 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.

Non Accepted Proposals

If your proposal is accepted for a session > 30 minutes long, we will cover your event ticket.

If your proposal is not accepted, you can buy a ticket at the same rate as was available on the day you proposed. We’ll send you a code.

Optimize Performance in Android Apps

Submitted Oct 17, 2013

Developing Android apps is easy. Making them perform better is a bit hard. The idea of this session is to showcase the lessons learnt from making the Firefox for Android run faster. From custom views to shaders to overdraws, the session will be filled with tips and tricks to make apps run at 60fps.


Building Android apps with XML and Java is easy. But making them run at 60fps is hard. Have your ever had a stuttering ListView that skips frames? Is your app filled with red color when the “Show GPU Overdraw” is turned on? Do you use a lot of views and not sure how to reduce them? Did you know that Twitter uses a single custom view for each row of tweet in their app? Then this session is for you!

The major topics of the session will include:

  1. Removing overdraw using Droid Inspector.
  2. Reducing views using compound drawables.
  3. Playing with shaders to transform bitmaps easily.
  4. Asynchronous loading of ListView images.
  5. Common Android UI pitfalls.

The session will have more code snippets. The session will also showcase apps like Firefox, Facebook and Twitter in 3D, and use them as examples to understand and relate to the problems.

Speaker bio

I work for Mozilla on their Firefox for Android application. I’ve been a major part of their native re-write, and brought down the startup speed of the app from 20s to 800ms. In constantly changing the UI for Firefox in the past two years, I have solved many common problems faced by apps. Being a part of the open source culture, I blog my findings at http://sriramramani.wordpress.com/ I’ve always felt that finding overdraw using UiAutomator and HierarchyViewer is not easy. This led me develop Droid Inspector (http://www.sriramramani.com/droidinspector) -- an Android tool that allows debugging apps in a 3D view. To get an idea of UI/UX and the user centric research, I did my Masters in HCI from Carnegie Mellon University.
