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

Forget SQLite and say hello to Realm

Submitted Sep 14, 2015

To introduce no sql database for mobile apps and to show how it can be used for Android development as replacement of sqllite.


Screw SQLite with no SQL databse designed for mobile. Realm is not an ORM on top of SQLite. Instead it uses its own persistence engine, built for simplicity (& speed). A true cross platform solution that replaces sqllite and core data on android and iOS.

Most android apps requires a persistance storage to provide caching and offline functionalities in the app. Currently there are very limited options avialble for persitance storage, most people rely on SQLite or file storage. If app’s backend is no sql there is an additional overhead of conversion with SQLite. SQLites api’s on android are complicated, most people inturn uses additional ORM layer on the top adding additional complexity.

In this talk we will be talking about Realm, how to use it in your app, perfomrance comparison for read, write, updates. Some pros and cons of using Realm vs sqllite. We will also be comparing realm agains CouchDB Lite another no SQL database for mobile from CouchDB team.

Here is a brief outline of what we will be covering :

=> Why a new database

  • Overview about sqllite, normalizations, pitfalls, queries
  • Lets look at some other mobile db options available, ORMs, other no sql
    => What is realm
  • More info about realm
  • Info about object references,zero copy etc
  • How Realm is good for mobile
    => Benchmark realm agains other db
    => Architecture of android apps with realm
    -zero cpy
  • annotations
  • realm proxy
  • pojo
    => Lets see some code
  • Add realm in app
  • Realm Queries, Schemas, Migration, Encryption in relam world
  • adapters, notifications with real app example
    => realm browser, stetho integration.
    => Realm limitations and some info about other DB like couchbase lite.


Basic understanding of Android application development, understanding of SQLite on android. Knowledge of any existing ORM on top if SQLite will help.
