Sixth edition of droidconIN.
droidconIN is part of the world wide series of conferences that happens in London, Paris, Berlin, Netherlands, Tunis, Ankara and Brussels. The first edition of droidconIN was at Bangalore in Nov 2011. The second edition in Nov 2012 was featuring General & Specialized Topics, Native + HTML5 and App Demos. The 2013 edition was about Systems, UX, Gaming, Business and App Demos. The 2014 edition featured dedicated tracks for deep dives into UI/UX, Data sync & versioning, App Demos and hardware. The 2015 edition had advanced technical talks with an emphasis on developing for resource contraint regions like India.
This edition spans two days of talks. We are inviting talk proposals for:
- Full-length 40 minute talks.
- Crisp 15 minute talks.
- Sponsored sessions, 40 minute and 15 minute durations (limited slots available; subject to editorial scrutiny and approval).
- Hands-on Workshop sessions, 3 and 6 hour duration.
Proposals will be filtered and shortlisted by an editorial panel. 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.
Selection process is stringent and we follow the procedure outlined in this flowchart:
A talk is NOT confirmed till speakers recieve explicit communication from us saying that it is.
A talk can be rejected at any stage by us if we feel the speaker will not fit in the conference for the year. A talk can be canceled by the speaker at any time for any reason. (We would appreciate it, of course, if it isn’t at the last moment.) Please note that selected speakers must mandatorily participate in two rounds of rehearsals before the conference. This not only helps us adhere to the HasGeek format and quality, but also helps speakers prepare better for the intended audience.
There is only one speaker per session. Entry is free for those who are selected. Due to budgetary constraints, we prefer speakers closer to home. But if we think you stand out, we’ll provide a grant to cover part of your travel and accommodation to Bangalore. Grants are limited and are made available to speakers delivering full sessions (40 minutes or longer) only.
Updated (6th September, 2016): We are currently looking for talks in the following topics:
- Toolchains - What’s the latest in developer toolkits to help with build systems (Gradle, Buck, etc), speeding up the dev feedback loop, etc.
- Kotlin - An experienced speaker to help breakdown what Kotlin is, why and who should use it.
- Firebase - A case study of Firebase in an medium/large app, with insights on it’s benefits, drawbacks, and when/where it makes sense.
- Everything else - Anything else of relevance to an Android developer that we might have missed out.
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.
For more information about speaking proposals, tickets, and sponsorships, contact firstname.lastname@example.org or call +91-7676332020.
Deadline for submitting proposals:
- Proposal submission deadline(updated): 19 September 2016
- Schedule announcement: 10 October 2016
- Conference dates: 10 and 11 November 2016
We expect you to submit an outline of your proposed talk – either in the form of a mind map, a text document or draft slides along with your submission. You can edit your submission at any time.
##Proposal submissions are now closed.
Jack, Jill & Java 8
This talk will go over the new Jack and Jill toolchain & the new Java 8 features that they bring to Android land. You will learn about -
- The existing Android toolchain of javac, dx, jarjar etc.
- How Jack and Jill replace the existing toolchain
- New Java 8 features that Jack brings
- Drawbacks to Jack you should consider before upgrading
Jack is Google’s new compiler/toolchain for Android. It compiles Java source into Android dex bytecode. It will replace the current javac, ProGuard, jarjar, and dx toolchain.
The talk will cover
- How both toolchains work
- What Jack & Jill do differently
- Why you should upgrade to Jack
- What some of Jack’s cons are
- Legacy javac toolchain: javac (.java → .class) → dx (.class → .dex)
- New Jack toolchain: Jack (.java → .dex)
- We’ll cover details about how both work
- Go over changes required in build.gradle if you wish to try out Jack
- Cover some gradle options that Jack provides
(these use anonymous classes and hence are compatible back to Gingerbread)
- Method References
- Type annotations
- Stream APIs
- Interfaces - default method implementations & static methods
- Repeatable annotations
- Transform API is not yet supported. This means that some libraries do not yet work with Jack. The most prominent example being RealmDB. Bugs filed here and here
- Lint detectors which operate on a Java bytecode level will not work since there is no intermediate bytecode when you use Jack.
- Jack is currently slower than javac + dx
I have been working on Android apps for the past 2 years. I am currently a freelance developer who works with Android and Python. You might know me from other events like PyCon 2014 where I presented a poster on Creating a Fall Detector using Raspberry Pi and Python or from my Android apps like, Search for Reddit.
