Come to Droidcon India 2015 to discuss how you’ve tackled each of these issues.

Criteria to submit

You must be a practising developer or designer and are expected to present original work that your peers — this event’s audience — recognise as being notable enough to deserve a stage.

If you are excited about someone’s work and believe it deserves wider recognition, we recommend you contact them and ask them to submit a proposal.

Selection Process

Proposals will be filtered and shortlisted by an Editorial Panel. We will notify you if your proposal is shortlisted. We urge you to add links to videos / slide decks when submitting proposals. This will help us understand your past speaking experience. Blurbs or blog posts covering the relevance of a particular problem statement and how it is tackled, will help the Editorial Panel better judge your proposals.

Proposers must submit presentation drafts as part of the selection process to ensure that the talk is in line with the theme of the conference, and to help the editorial panel build a strong line-up for the event.

There is only one speaker per session. Entry is free for selected speakers. HasGeek will provide a bursary to cover part of your travel and accommodation in Bangalore. Bursaries are limited and made available to speakers delivering full sessions (40 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.

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.

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.

We are no longer accepting proposals. The deadline for submissions was Wednesday, October 21st, 2015

Memory Dumps: Going beyond the memory leak

Submitted Sep 22, 2015

To show developers a new way of using memory dumps to analyze those really tricky bugs (where stacktraces and logs are not enough)

Outline

Memory dumps have long been used in Java to find and analyze memory related issues such as memory leaks.
However, with the wealth of information available in every memory dump, why are we not using them when trying to analyze other bugs as well?
This session will outline a new way of working with memory dumps what will allow you, the developer, to harness all this powerful information when analyzing crashes and bugs.

Presentation Outline

1. Introduction

Who am I? What is Badoo? and why do we care about memory dumps?

2. What is a memory dump

A brief introduction to memory dumps covering questions such as: What is a memory dump? and What information can we find in a memory dump?

3. Current use cases

An outline on the most common uses cases for memory dumps (on Android), focusing on memory leaks and OutOfMemoryErrors.

4. Beyond the memory leak

Looking back at the information that is available to us in a memory dump, what could we do besides use them for finding memory leaks?

5. The case against HPROF

Why is HPROF not a good file format if you want to go beyond memory leaks? What could be

6. Introducing BMD

An introduction to the Badoo Memory Dump (BMD) file format and the process that went into developing it as a replacement for HPROF memory dump files.

7. BMD vs. HPROF

A comparion of BMD and HPROF, showcasing the advantages of using BMD.

8. Demo #1: Recovering a View Hierarchy from a memory dump

A real life use case demonstration showing how you can use the tools developed by us at Badoo to extract useful View Hierarchy data from a memory dump.

9. Demo #2: On device collection and conversion of memory dumps

A quick demo showing how you can integrate our tools for collecting and converting memory dumps into your Android app.

Speaker bio

Originally from Sweden, now living London and working for Badoo as an Android developer. With 8 years of professional experience in the mobile industry starting with J2ME Feature Phones at SonyEricsson before moving on to Android. When not developing Android apps I enjoy creating tools to make life for me and other developers easier.

Besides being a dedicated software developer I also enjoy tinkering with Open Source hardware and electronics on my spare time.
