Groovy for Android

by Anas Ambri

About me: An apprentice in the growing domain of software development, with a meticulous interest into solving problems (with software), an appreciation for open-source solutions, and an annoying tendency to have an opinion about almost everything.

About the topic: Since the advent of Swift on iOS, many Android developers have been looking into a similar higher level construct to develop apps on their favorite platform. Today we will talk about some of the current options, and focus mostly on Groovy. Finally, we will show how we used Groovy at Guestful to develop our app, as well as the lessons learned. Spoiler: the app was actually delivered. Duration: ~20 min + questions

Android Account Manager

by Simon GUEROUT, of Sidereo Solutions

Gestionnaire de comptes d’Android

Pendant cette présentation, je vais vous présenter un cas d’usage du gestionnaire de comptes d’Android.
Il n’est pas rare pour une application d’être connectée à un service.
Ce lien peut être fait en utilisant le gestionnaire de comptes pour simplifier la gestion de la synchronisation des données avec le service.
Dans le cas d’usage que je vais présenter, nous allons voir comment utiliser ce gestionnaire non pas pour un seul service, mais pour une multitude de sources de données.

During this presentation, I will talk about a use case of the Android Account Manager.
It is not rare for an application to be connected to a service.
This link can be managed using the Android Account Manager, in order to simplify the data sync with the service.
In the use case I will be presenting, we will see how I used the Account Manager to connect not only to a single service, but to different sources of data.


August Meetup

2014-08-09 |by droidmtl | Comments Off on August Meetup | Events, Uncategorized


Hello everyone, hope you all enjoyed your summer so far!

Our next meetup will be taking place Wednesday August 20th, on the 3rd floor at Notman House. (Same awesome space where we held our Android Wear hackathon early this summer.)

We have 2 great talks scheduled, and a small recap / show and tell session for the various toys we managed to bring back from Google I/O. As always you’re welcome to drop by to introduce yourself and your projects to the community.

  • 17h30: Google I/O Recap
  • 18h30: Recognizing Speech on Android
  • 19h30: Byte-Code Weaving on Android
  • 20h30: Beer and food, @Ye Olde Orchard Pub

You can get your tickets on our Eventbrite.


Google I/O 2014 Recap

Small informal presentation reviewing what was announced at Google I/O, with small hands-on + Q&A session for:

  • Android Wear
  • Android TV
  • Google Cardboard

Recognizing Speech on Android

by Gina Cook – Android Developer for iLanguage Lab

In this talk I’ll show you how to use speech recognition in your own Android apps. The talk will have something for both beginner and advanced Android devs, namely I will show two ways to do speech recognition: the easy way (using the built-in RecognizerIntent for the user’s language) and the hard way (building a recognizer which wraps existing open source libraries if the built-in RecognizerIntent can’t handle the user’s language). While I was in Batumi my friends and I built an app so that Kartuli users (code) (slides) could train their Androids to recognize SMS messages and web searches. Recognizing Kartuli is one of the cases where you can’t use the built-in recognizer. Kartuli spoken by only 4 million people in the country of Georgia: that is roughly the population of Montreal and surrounding areas. The talk will start with a demo of our Kartuli trainer app to set the context for the talk, and then dig into the code and Android concepts under the demo.

  • How to use the default system recognizer’s results in your own Android projects,
  • How to use the NDK in your projects,
  • How to use PocketSphinx (a lightweight recognizer library written in C) on Android

Byte-Code Weaving on Android

by Stéphane Nicolas – Senior Android Developer for Groupon Canada

During the last few years, we have all assisted or participated to a small
revolution on Android : the emergence of annotation processing. Many
popular libs now rely on annotation processing during build to pre-compute
a lot of stuff that will boost them at runtime. Let’s think about Dagger,
ButterKnife, Hugo, RoboGuice, BoundBox, Memento, IcePick, etc.

All those libs use annotation processing to generate data as Java source
files that are executed at runtime. Nevertheless, writing annotation
processors is far from obvious as they are based on the annotation
processing API that is very difficult to understand.

But there is an alternative : byte code weaving. This technique is popular
in the Java World for a large variety of applications : from creating mocks
(easymock/mockito) to data persistence (Eclipse Link, EBeans, etc.), or
Aspect Oriented Programming (AOP).

So, why don’t we use post-compilation processing on Android too ?

This sessions offers an overview of different byte code weaving techniques
and will examine whether they can be applied to Android. We will see how
post compilation byte code weaving can be used during Android apps’ builds
when using either Gradle or Maven.

Finally, we will present 2 libraries : AfterBurner & Mimic. They are based
on javassist, and aim to make byte code manipulation easy for Android. We
will go through simple use cases that will show us how to eliminate all
boiler plate when using our favorite libraries and boost apps using post
compilation byte code weaving. Byte code weaving could even be used to
normalize new and simpler programming techniques for Android that could get
standardized via Android Specification Requests.

March Meetup

2014-02-25 |by droidmtl | Comments Off on March Meetup | Events, Uncategorized

Hello everyone, our next meetup will be taking place on wednesday, 5th of March, 2014 at 18h30, at l’Amère à Boire.

We have two great talks this month! François Proulx will give us an overview of the latest trends in mobile security, and Philippe Breault will present an introduction to building Android Studio plugins.

Latest trends in Mobile Security

by Francois Proulx


François Proulx is a senior mobile application developer who has worked on dozens of iOS applications since the very beginning of the Apple iOS platform. Over the past few years he has switched his focus to security. He spends a lot of his free time participating in Capture the Flag events (CTFs) and organizing the NorthSec security competition.


Last AppSecUSA 2013 had a great line up of talks, especially regarding mobile applications. This session will be covering all the hottest presentations about mobile security by doing an overview from what we saw at AppSecUSA, all with some slides and snippets of presentations that was recorded at the event. Discussion will be encouraged within the audience as this will be more a dynamic event than a regular talk.

Introduction to building Android Studio plugins

by Philippe Breault


Hey There!

My name is Philippe Breault, I am a software developer living in Montréal (Canada) and my job/hobby is Android.

I have been working on the Android platform since 2010 and I hope that sharing what I have learned will help people get proficient in Android faster!


With this presentation, Philippe will be showing us how to develop plugins for Android Studio. Note that all products based on the IntelliJ Platform (IntelliJ IDEA, RubyMine, WebStorm, PhpStorm, PyCharm and AppCode) share the same underlying platform API, and as such this talk will be of benefit to anyone working with one of these IDEs.

Tickets here

Hello everyone, our next meetup will be taking place on 27th of November, 2013 at 18h30, in Notman House as usual.


We’re a bit short notice this month, and we wanted to open the floor to anyone who’d like to get a hand at presenting an API, library, open source project or technology that is dear to their heart. The format we’re aiming for is small and informal, timeboxed to anything between 10-30m long.

As of now we had people interested in presenting What’s new in Android 4.4, a short tour of Dagger (the lightweight Injection library) as well as Retrofit (a Rest client API).

As usual, you’re welcome to come by and make announcements to our community. We’ll probably be going out for food after the event, so we hope you’ll stick around and hang out!

October Meetup

2013-10-15 |by droidmtl | Comments Off on October Meetup | Events, Uncategorized

Hello everyone, our next meetup will be taking place on 30th of October, 2013 at 18h30, in Notman House as usual.

We have a great guest this month, Macy Kuang, with a presentation on Google Glass. We’ll also have Etienne and Boris who will be doing quick ~20m introductions to the Gradle Build System and the new Android™ KitKat® Release.

Google Glass Development

by Macy Kuang


Macy Kuang is the Founder of Miaomiao Games. She has worked on titles such as Modern Combat, Asphalt and Fashion Icon while at GameLoft. In addition to programming, Macy has been on the organizing committee for AndroidTO, the annual Android conference, and a regular contributor to the Google Developer Group, Toronto. Macy participated in the Google Glass Foundry in New York in February 2013 and is now a Google Glass Pioneer, working with developer versions of the hardware and associated APIs.


Google Glass has been on developers hands for over half a year, and this presentation will cover the fundamentals of the technology Including how it works, what its current capabilities and limitations are, and how to develop for it. The Google Glass hardware takes into account some unique considerations not commonly seen in most mass-market devices, including bone conduction for speech and audio transmission, gesture ‘wake-up’ and On-Head Detection. Along the lines of the development process for Google Glass, this session will address various implementations, leading with applications created by Glass Pioneers at the Google Glass Foundry (the Google Glass Developer Hackathon held in New York and San Francisco). Demonstration of existing apps on Google Glass will cover pros and cons emerging as Google Glass use cases transition from novelty and gimmick to practical utility.

Android™ KitKat® Release

Boris Dubois


Développeur Android @ La Presse


We’ll look into what’s new for the platform.

Gradle Build System

Etienne Caron
