Developing Android applications is a powerful way to connect people with the information they need the most. Apps are for living your life: daily commutes, traveling abroad, handling your money, communicating with family, and much more! This places the responsibility of engineering top-notch software squarely in the laps of us developers. Unlike doctors, we were not required to take an oath or pledge when becoming Android Developers. However, we can still learn much from the principles behind the phrase, “First, do no harm.” In this talk, we will discuss over a dozen tools that are at your disposal as a developer which can enable you to provide high quality applications to your users. Thus allowing you to first, do no harm!
Chiu-Ki is an Android developer with a passion for sharing her knowledge. She blogs about Android, speaks about Android, draws about Android, and makes videos about Android. She is very active in the Android community, and has been recognized as a Google Developer Expert for her extensive knowledge of Android.
Think of an Android expert. Why do you consider this person an expert? “She knows a lot about Android”, you say. But how do you know? You know because she shares her knowledge, through blogs, talks, StackOverflow etc.
Experts are just that, people who share their knowledge. Sharing puts you in a positive feedback loop: the more you share, the more knowledgeable you become. Let me walk you through some concrete steps you can take to start sharing and build up your expertise.
Nathan Eagle is the CEO and co-founder of Jana, the largest provider of free Internet in emerging markets. Born out of his time as a Fulbright professor in Kenya, Nathan began Jana from the insight that smartphones can be used not only for global communication, but also data sponsorship. He founded Jana with a simple, yet powerful mission—to make the Internet free for the next billion. Nathan saw first-hand how affordable mobile data empowers users in these markets through his work teaching app development at the University of Nairobi, Kenya. It was there that Nathan and his students created an SMS system that became the technical infrastructure of Jana. Nathan realized that the sponsored-data model can both power smartphones and empower users.
Nathan graduated from Stanford University with a B.S. in mechanical engineering and master’s degrees in management science and engineering and electrical engineering. His Ph.D. from the MIT Media Laboratory on Reality Mining was declared one of the “10 technologies most likely to change the way we live” by the MIT Technology Review. He was also named a Technology Pioneer by the World Economic Forum in 2014.
More than 4 billion of the roughly 7 billion people on Earth now have the ability to get online, thanks in large part to the rise of Android. Yet, there are 1.3 billion smartphone users living in emerging market countries like India or Indonesia who are limited by the relative high cost of mobile data. 500 MB of data costs a user in India 17 hours of minimum-wage work in India. In the United States, the same amount of data costs only 3.5 hours worth of minimum-wage-work. But, the hunger for Internet access and smartphones is not slowing down. By 2020, emerging markets will have more than 2.5 billion smartphone users and the demand for Internet access will increase by 500%.
In his closing keynote, Nathan will address the importance of Internet access via smartphones and the powerful role that Android development plays in getting the next billion online, He will ultimately aim to inspire Android developers in Boston to create technologies that will change the future of the world’s economies.

Ever wondered what your Android sees? how does it perceive(or not) the outside world? it would be really nice for our phones to see as we see and if they’re not yet capable, why not teach them? the way to do it is using Machine Learning, a (kind of) new trend that’s here to stay, and with so many different areas to explore is up to us to pick one we find interesting. Well, my take is on computer vision, so buckle up and join me in this journey, let’s review options for computer vision on mobile, explore different examples and walkthrough the basics of several vision APIs.
Andres Colubri is a researcher working in the visualization and modeling of biomedical data, as well as with interactive graphics applied to arts and design. He originally obtained a doctoral degree in mathematics back in his native Argentina, and later pursued an MFA at the Design Media Arts department at the University of California, Los Angeles. He is also a member of the Processing project, a programming language, environment, and community focused on making code-based art. He is currently developing the next version of Processing for Android, which includes support for wearable devices and VR.
This talk will give you an introduction to Processing for Android. It will cover the basics of the Processing language that allows to effectively program interactive graphics in 2D and 3D, and will describe the application of these techniques to different types of Android devices: smartphones, tablets, wearables and smartwatches, as well as to Cardboard-compatible devices in order to create VR experiences. Processing started in 2001 at the MIT Media lab as a project to increase software literacy in the arts and design, and today it is used around the world as a teaching and production tool. An advantage of Processing for Android over more complex programming environments is that it allows the users to focus on the interactions and visual output of their code rather than in the implementation details of the Android platform.

In Android Nougat 7.1 the ability to create app shortcuts was introduced. Implementing shortcuts into your app helps guide users to specific parts of the app. If implemented correctly, it can help simplify the way users interact with your app, thus providing a delightful user interface experience. In this talk we will see an example of how to create app shortcuts. We will also talk about the different kinds of shortcuts you can create (static and dynamic) and how to chose which one to implement. Lastly, we’ll talk about how to create a proper back stack of activities once the user launches the app through a shortcut. By the end of the talk attendees should have a clear understanding of how to help increase user engagement by making it easier for users to use their app.
Daniel is an Android Software Engineer at Groupon. He is a passionate Science geek with special interest in performance, design and security.
Before joining Groupon, he worked as a Web and Android developer for 6 years, participating in the development of some Android applications such as Hostelworld, Bonobu and now Groupon.
He is keen on contributing to the community by writing articles and collaborating on some open source projects: Toothpick, Dart & Henson, etc. Moreover, he has taken part in some conferences: Berlin Droidcon 2016, Mobile Era 2016 or AndDevCon San Francisco 2016.
You find RoboGuice simple but slow? And you think Dagger 1 & 2 are fast but complex and bloated? Toothpick is the best of both worlds!
Toothpick is a scope tree based, runtime but reflection free implementation of JSR 330. It is pure Java, with a special focus on Android. Toothpick is fast (even faster than Dagger 2 in some cases!) and is simpler to use, with less boilerplate code. Its syntax is very close to Guice. It supports named dependencies, lazy dependencies, providers, and has built-in support for custom scopes. As compared to Dagger 2, Toothpick provides more powerful testing support, allowing you to leverage DI to mock dependencies using either mockito or easymock. Its explicit scope tree helps developers to build more robust apps. It provides more fine grained control to easily implement complex user flows that span multiple activities or state preservation across configuration changes (e.g. rotations), a common issue when implementing the MVP pattern.
During this talk for experts, we will introduce Toothpick, its main features and how it compares to other DI libs. We will explain how Toothpick scopes and scope annotations can solve advanced use cases when developing Android apps.

Tying up the users to your app is the most important and yet one of the most puzzling parts. Users will already have a strong impression about your app the first 30”; Yes, including splash screens or empty lists and loading indicators, that are pretty much impossible to avoid in most of the apps. So all we need is some stardust, say the ‘abracadabra’ 3 times, and the boring splash screen or the empty screen will transform to something entertaining and interesting that will impress our users! Wait… what?! How do I do this? A great place to start is learning to leverage Android’s animation SDKs 😉

In the 8 years since the release of the first commercial Android device, we’ve seen screen resolutions go from thousands of pixels to millions, cameras from 3MP to 13MP, and cores from 1 to 8 – but battery life is staying the same or even getting worse! This makes it even more important to be a good battery citizen and leave some juice for your users’ other apps (they do use apps other than yours, right?) In this session, we will explore the different battery tools and resources available for profiling – like Trepn Power Profiler and Battery Historian – and use them to identify common battery pain points in your app. We’ll also cover best practices for power-sensitive development so you can prevent battery drain problems from the beginning.

Whilst crafting products, it’s common for developers to find difficult to ship products and fast whilst also creating a codebase that allows you to easily do so. Whilst at the beginning of a project lifecycle you are free and able to move quick, it’s the technical debt build up that will make it hard for both you and future developers to move fast and maintain your codebase. Clean Architecture allows you to create a codebase that is both easy to maintain and extend, whilst also opening up the ability to thoroughly test each layer of your codebase.
Following Clean Architecture has made me discover the advantages that it can bring our projects. Coupled with the following of SOLID principles, codebases can not only become cleaner and well tested, but they can move in a direction that allows us move fast whilst remaining easy to work with at the same time. In this talk, we’ll be looking at what clean architecture is, why we should bring it on board and how we won’t be looking back.

I will demonstrate how RxJava can solve a common problem when using remote APIs in Android: ‘callback hell’. We may find our code riddled with nested branching and anonymous inner classes as a solution to complex API interactions. For example: ‘First initialize this API if not done already, then get this model object. If it exists, make these additional calls, but if it fails, make this other call instead.. Do this as many times as necessary to get all objects.. oh, and order me a pizza’ (just kidding about the pizza). This is a real-world Android example using an IoT Particle Photon shooting projectiles across the room with compressed air! (not kidding). RxJava can solve ‘callback hell’ and I’ll show you how!

With 2.2M apps in the Google Play store, Android developers now have to compete for awareness, engagement and retention of users, for their apps. Traditionally, this has involved using multiple toolkits and managing the complexity of costs and interactions across them. With Firebase Analytics, the process is unified (single toolkit), cost-effective (unlimited & free) and comprehensive (standard & custom events) — not to mention easy to use.
In this talk, we will take a look at how easy it is to integrate Firebase Analytics and use the resulting insights to not just understand user behaviors, but also to improve user experience and engagement (with data-driven UX decisions) and to better monetize those interactions. The first half of the talk will focus on the Firebase Analytics API (front-end) and its usage (with code) to capture user events and establish relevant contexts. The second half of the talk will focus on the Firebase Analytics Dashboard (back-end) and its usage to filter, track and visualize user behaviors in individual and collective contexts.
Finally, we will explore popular scenarios requiring behavior analytics and walk through how these can be implemented using the APIs and Dashboard provided by Firebase Analytics. The talk will conclude with pointers to resources, and a brief review of other Firebase features that enable (or are enabled by) Analytics.
Paul comes from a family of coders. His father started things off at Data General working on projects like the Soul of a New Machine. Then he taught his three sons to code in the 90’s. After long stints at Allaire, Macromedia, Adobe, Bullhorn, and Brightcove, Paul is now at TripAdvisor, where he’s loving the short commute, free lunches, and fun challenges that come with working with roughly 50 Android engineers all contributing to a single app and releasing every two weeks. It’s safe to say that his two sons are likely to also become coders when they grow up.
Discover how the TripAdvisor CI infrastructure improves the productivity of our engineers by allowing them to implement a feature, test it, open up a pull request, and move on to another task. If issues are discovered during the CI builds, engineers can address them and update the pull request to repeat the process. If all the builds pass, the engineer can be confident that functionality in other areas of the product has not broken and can safely merge to master. If engineers had to run all the existing tests locally before merging to master, it would currently take over 10 hours. 10 hours is a long time to tie up CPU and memory resources on a developer’s machine. Learn how TripAdvisors uses tools like fastlane supply, HockeyApp, Robolectric, and GenyMotion to continuously deployed master, prerelease and release branches!

The current way native mobile development is taught is at best incomplete and at worst completely misinformative. This session will be presenting a more holistic way of building for native mobile Android. We begin by showing the the highest quality resources to learn (free). Then the session discusses what most mobile developers wish they knew before they started. The best architecture, design patterns, libraries, tools, tips, tricks and common mistakes to avoid before writing the first line of code. We follow with a review of how major companies develop mobile apps internally by exploring their open source projects and current publications regarding their latest advancements in native Android mobile development. We conclude by reviewing the extensive research and key insights behind using analytics to drive distribution and monetization. Slides: https://goo.gl/dPDskh

Kotlin does a lot for us in the way of reducing boilerplate. But what is it really doing? We will be inspecting some decompiled Kotlin to discover how it does its job. By looking underneath at how it handles data classes, lambdas, and delegation, we can better understand how the language executes what we write. If you’re curious about the language, or already using it in production, you should walk away from this investigation with a deeper understanding of Kotlin, and some tools for continued exploration.
