GDG Montreal Android January Follow-up

Hello everyone,

We’ve had a blast this last Wednesday at the January Meetup, and we wanted to send out a little follow up email on some subjects we touched upon


I’d like to say a quick thank you to everyone who volunteered to give a talk over the next couple of month, we’ll be contacting you this week to try and schedule the February and March lineups, and give you a chance to prepare.

If you are interested in giving a talk, please reach out to Etienne or one of the other organizers and we’ll add you to the upcoming lineup.


I personally received a lot of positive feedback during the Meetup for the idea of organizing App Design Workshops, and to explore some mobile-friendly Client-Server Architecture setups.

We’ll be polling you in the coming weeks to pick between our different subjects, and different timing options (Evening sessions, or week-end afternoon sessions? TBD…)

Android Jobs

Radialpoint has reached out about a Full Stack Mobile Developper position. You can find out more about them here. (Worth a look, they do interesting things)

We also had Aurore visiting from Nurun, another interesting company, who are currently looking for senior Android developper. See the posting here. Find out more about Nurun here.

Managing a task scheduling queue

by John Brohan

“An App for Grandma” operates continuously and autonomously, it requires no input from the user (typically an elderly person unwilling to press any buttons).

The “TimeActionQueue” schedules many different kinds of events:

  • Show the next picture in a gallery in nn seconds
  • Process a GCM broadcast message to download a photo
  • Start a Skype session
  • Send an email to remind friend to send more photos every 10 days
  • Manage the steps to setup and refresh Google Cloud Messaging
  • Display the time in the Action Bar to 5 minute precision…….

Things you need in a TimeActionQueue:

  • Create an action
  • Add a new time action
  • Add unique and Poll
  • Does not need a destroy (discuss)

Debugging aid for coping lots of enums by getting the names of enums into the debug log.

Question getting from static functions to non-static methods in an Activity?

Custom Views and the Hierarchy Viewer

by Etienne Caron and François Légaré

Recent studies have consistently shown that latencies in the order of a 100 milliseconds can have fairly big impacts on usage patterns. Worse yet, the effects of latency exposure tend to linger on. Once your users are exposed to it, it can take weeks before they go back to their original usage pattern!

This highlights how important it is to optimize your UI. Thankfully you have multiple tools on Android that can help you achieve this.

In this session, we’ll look at the Hierarchy Viewer and how to use it (and some other onboard debugging tools) to create truly responsive UI and UX.

We’ll also take a look at the basics of Custom View creation, and how to define custom-made XML attributes to leverage the Android Interface editor.


December Meetup

2014-11-27 |by droidmtl | Comments Off on December Meetup | Events, Uncategorized

@ Brutopia

1219 Crescent Street, Montréal, QC

This month we have two exciting presentations, and lots-o-beer!

Our usual location (Notman House) is unable to accommodate us so this month we are going to be happily hosted by Brutopia, a popular brew pub located downtown at Metro Guy-Concordia.


Note, we will start at 6pm (presentations start at 18h15) to accommodate the happy hour crowd.

  • 18h00: Arrival and socializing
  • 18h15: Contrôler ses écouteurs Bluetooth avec sa montre
  • 18h45: Testing Android with Computer Vision
  • 19h30: Beer and food, @Brutopia

Contrôler ses écouteurs Bluetooth avec sa montre

Avec Boris Dubois

Contrôler ses écouteurs Bluetooth avec sa montre : débuter avec des interactions simples sur Android Wear en respectant les design guidelines.


Testing Android with Computer Vision

How to setup and tweak Sikuli tests for Android

With Farah Abbasi & Gina Chiodo

In this talk we will show you can test image heavy, and/or legacy/hybrid android apps using OpenCV (computer vision) and Sikuli. Sikuli is a framework which automates anything you see on the screen. It uses image recognition to identify and control GUI components. It is useful when there is no easy access to a GUI’s internal or source code, or writing tests crosses layers of technologies ie in a Cordova/HTML5 app running in a webview.

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.
