Now that Kotlin is the preferred language of Android developers, what is the best library to work with SQLite databases using Kotlin? Room just released support for Kotlin Coroutines, and SqlDelight released support for Kotlin Multiplatform. Room has great documentation and hides a lot of implementation detail, while SqlDelight lets you write raw SQL statements with an Android Studio plugin and then generates type-safe code for you. In this session, you’ll see a rundown of these two libraries, along with live coding demos to help you decide which library sounds right for you in this Kotlin world. [Read more…]

Two longtime friends with complementary skills meet a new mobile SDK for building high-performance apps from a single codebase, what could go wrong? Flutter is quite powerful but with great power comes great responsibility. Using widgets, building a meaningful UI in a new way, finding that library we need and getting used to a different architectural approach are some of the many challenges we face as developers and designers when going into the cross-platform world. In this talk, we’ll review some of the advantages of using Flutter, how to tackle common challenges when adopting it and how can it spark a better collaboration between designers and developers, including roles and responsibilities, a well-defined feedback process, and our own experience while building an app. Interested?

Chances are that you’re a teacher – whether you’ve formally taught in a classroom, shared an engineering experience as a talk or blog post, or helped out someone new on your team. Since you’re a teacher, you should care about being a good teacher. Good teaching empowers those around you and nurtures healthy technical communities. Also, teaching doesn’t need to be entirely altruistic – often the best way to truly learn something is to teach it. My education career started over a decade ago. It has included teaching at an all girl’s STEM school in Rwanda and for the last five years as an online instructor for Google’s Android courses. The Google courses are by far the biggest “classroom” I’ve been a part of, with a diverse and driven pool of students. Android has also had seismic changes over the past few years. These facts combined make Android a subject where teachers need to continually adapt, iterate and hone their skills. In this talk, I’ll share what it’s like behind the scenes: scripting, filming and producing Android classes for hundreds of thousands of students, including what we got right, and what took a few tries. From this, I’ll cover reflections and practical takeaways about teaching Android and teaching in general. Because I am a teacher and so are you! [Read more…]

PLURALSIGHT DROIDCON BOSTON 19 WRITING TESTS THAT STAND THE TEST OF TIME-JGTiSO
English | Size: 250.74 MB
Category: Tutorial


One of the promises of test-driven development is the confidence and ease with which we can refactor our production code. However, sometimes we find ourselves in situations where our tests are too coupled to our code and we have to change the tests every time we update the code. At this point, we start wondering if the tests are worth it. If you have ever found yourself having to update your tests every time the behavior of a dependency of a class changes, then this talk is for you. This talk is to share some patterns, tools, and examples that can guide us to write more maintainable tests. We will look at why we need tests in the first place, how writing tests is an investment that will save time in the future. We will also look at some causes of unmaintainable tests (for example using a wrong test double, testing implementation details and not general behavior) and how to overcome these problems. With the use of examples from everyday Android development, we will learn how to avoid brittle tests. You will leave the talk having a clearer understanding of why tests are important and worth the time and ultimately be able to apply the tips to write robust and more maintainable tests.

Breaking away from the traditional steps of a design sprint, we blur them together to further reduce the development cycle in what we call “Building at the speed of thought”. Over the years my group has been perfecting how to build world-class Android Apps at the speed of thought first for hackathons, then products and now for design sprints. In this session, we will detail the “Speed of Thought” methodology, steps, tools and components involved. We start by utilizing a design sprint to explore the power of mobile and how it fits into the market/problem we are trying to solve. Then focusing on the crucial step in a design sprint, we build high fidelity prototypes in rapid succession utilizing the JetPack Android software components (UI, Behavior, Foundation, Architecture) to take full advantage of the Android platform. We do this by leveraging the design features of Android Studio (material components/theme editor, constraint library, motion editor) along with open source/industry resources to build an intuitive and beautiful UI. Once the UI framework is done, we write the Kotlin application logic utilizing the Android Architecture Components with data binding connected to Firebase for the synchronized backend. With our application finished we execute our strategy for marketing, distribution, and monetization guided by Data-Driven Ethnography (DDE). At the end of the session, the audience will have a good idea of how in rapid succession all these tools and components come together to produce magic. [Read more…]

PLURALSIGHT DROIDCON BOSTON 19 ASYNCHRONY IN KOTLIN HOW YOU CAN CHOOSE BETWEEN USING RX OR USING COROUTINES-JGTiSO
English | Size: 218.77 MB
Category: Tutorial


The time is here to start thinking about the architecture of your Android app. You know your app will be all Kotlin (right?) it needs to do network requests, and it must communicate with a Bluetooth device. That means that it must deal with asynchronous programming so that it can receive and send data from the network and the device, while your UI
keeps running as smooth as butter. There are a few choices to accomplish this, such as using plain Threads, AsyncTasks or the popular Rx Java framework if you dread to manage threads in your own code (who doesn’t). In this talk, we’ll narrow down the choices to two candidates. The first one is the popular Rx Java framework and the second one is the newly minted Coroutines feature in Kotlin. We explain how they work and give you a checklist so that you can figure out which one suits the architecture of your app and your team of developers best. After all, you and your team want an app that is a pleasure to build and that your users will love! [Read more…]

Did you know “neural-network based classification” is really just a fancy way to squish a bunch of data until all the things that look alike are right next to each other? Machine learning is permeating every facet of our lives, from learning our preferences to self-driving cars, but what happens when you apply neural networks to code quality.how do you even view code as data? The key ideas are pretty easy to summarize and fun to play with. This talk will provide an overview of fundamental concepts of machine learning, and then delve into how it can be used to analyze and improve code, provide pointers to available commercial and open source tools and discuss what’s been achieved so far (coding in English, context-aware code completion, automated Stack Overflow). The talk will close with speculation on where the field is going, and how machine learning won’t take our jobs, but hopefully will take some of the work we don’t like doing. [Read more…]
