At Rakuten we built an app performance tracking SDK that automatically measures network and UI performance with 0 lines of code on the app side.
The SDK weaves measurement statements into application's bytecode at compile time, so that you don't have to write that repetitive code.
After internal release, several rounds of improvements and successful deployment to millions of users we open sourced the SDK last year.
In this talk I will share how the sausage is made hint: byte code weavingthe interesting details we encountered during development e.
Developer communities love to follow the hype - new programming languages, frameworks, libraries, architectures, tools.
Did you ever deal with… …a lack of motivation, boredom and depression?
Or the one that always over-promises and under-delivers?
Or the one in the remote office that seems to do nothing all day long?
These questions effect everyone, but we rarely ever talk about them in the developer community.
In this talk I will explore how we view our craft, work and life, how we can approach it on personal level and how good management can facilitate better work and life.
The first lessons of an apprentice cook typically focus on identifying quality.
Reinforced by repetitive acts, which helps understand the product and the click here />This training only focuses on the detail rather than the bigger picture.
With these new skills a cook learns how to adapt.
Once they have a strong grasp of the fundamentals cooks are less fearful of experimentation.
Adapt, try new things, overcome and learn from your mistakes, repeat.
How well do you think you'd cope if you had to be a professional chef for a day?
The path of becoming a senior Android developer can be very similar to the one cooks take to become chefs.
I want to learn from chefs and their journeys and apply it to our own craftsmanship.
I want attendees to learn what it takes to become a good Android developer, what it means to be senior developer, and finally how to lead a team successfully.
We work in teams.
We work with people: other developers, or designers, product managers, project managers.
We underestimate the work it takes to build a good team.
A team that functions and is productive, a team that solves problems, a team that knows how to communicate, and that completes tasks.
We even underestimate how many skills each person has to learn to make the team function.
But these mistakes are not isolated to cooks and chefs, we can see them in our own teams frequently.
With this talk I will investigate what constitutes a good team, what skills are needed and what the most common mistakes are that make teams fail.
Attendees will walk away knowing what actions and skills they will need to work on to make their team better.
This talk is about team building and dynamics.
As a candidate, interviewing for a new job can be quite stressful and time consuming.
It feels like you are being put through an exam.
Often, we forget we are also evaluating the company we are interviewing with, especially when we start interviewing for the first time, and it is hard to know what to look for.
On the other hand, interviewing candidates for a position can be stressful too.
You want to find the perfect person to join your team, but there are many factors that feel out of our hands e.
We need to effectively control the factors that we can.
With this talk we want to focus on the whole process of finding the right people to work with, from the job advert to the offer.
And we want to do it from both points of view, as the company and as the candidate.
We want to show candidates behind the scenes of the interviewing process, to make it feel less intimidating.
We want to teach them how to choose a job and a company that fits with them.
We want to give some tips on how to prepare for interviews, and the sort of exercises they might encounter.
We also want to help companies improve their hiring process.
There is no solution that works for everyone, but there are patterns everyone can follow to do better.
We want to show them how to reach candidates, make sure qualified candidates apply, show them how to deal with the unavoidable biases they will face, help them understand the pros and cons of different types of exercises, and finally, help them find the perfect new hire for their team.
Hiring and interviewing is not easy, and there is no easy solution to it.
But we hope that with this talk we would make it a little bit better for everyone involved.
How do you check the apk size, implied feature changes and permission changes?
How about design assets, license files and proguard rules?
Do you run any static analysis?
How to see it?
Are you handling these matter manually?
Didn't you fail to handle them?
Perhaps, do you ignore some see more the stuff.?
For example, it would be dangerous if new apk contained new permissions but you couldn't notice it, right?
You should be aware of them but it would make you work harder.
We are engineers so we should go with lazy methods.
Part of the Android SDK, it is most commonly used to view the logs continuously being emitted within a device via adb lolcat or to run commands directly on device via a shell.
But it is, as its name suggests and as you might already know, also a bridge to a variety of other functionality and information.
Have you ever wondered how adb does its magic?
In this session, we'll dive right into the deep end and take a peek under the hood to understand how every Android developer's favorite tool works.

Intended AudienceAnyone who has had PR reviews.
In this talk, we plan to speak about how a 私の近くのカリフォルニアのカジノの結婚式 can make a collaborative code review, especially on Android app development.
Android app development requires the reviewer to take into account various considerations; while there are some useful tips for the reviewer to find out potential bugs or improvements in the code.
First, we define what a good code review is and explain the typical steps of a good code review.
We think a typical process of a good code review is as follows: 1.
Understand the goal and the background of the change 2.
Run the app and verify the behaviour 3.
Read the code and the layout XML carefully 4.
Add any comments you come up with in your mind 5.
Take back and think if there might be a better way 6.
Have a conversation with the reviewee Then we will dive into each step and show some key tips for the review of Android development with an example from our real experience.
For example, we believe running the app on a device is crucial to the review of the Android app code, so we will give an example and explain why it is important.
Instead of talking about important yet too general things around code review, such as wordings of the comments, whether or not pointing out a format, etc.
But, what if there are no plugins for what you need?
What if you just need something simple?
What if you want a build flavor without actually click here yet another build flavor?
In this talk we will explore just how programmable we can make our builds without needing to create any plugins, we will look how you can add build parameters, how you build can dynamically reconfigure its self-depending on flavor, the environment it's running in, and just how easy it is to automate anything with just a few Gradle scripts アイアンマンゲームを無料でダウンロード some tasks.

Just like the financial startup and the largest chat service collaborated in Japan, the boundary between financial institutions and others are no longer distinctive.
We all know universally interconnected financial data is a good UX for users because users regained a choice to control the data.
To protect such innovation, OpenID Foundation has been working out to define global standard called Financial API FAPI including security profile for Android.
The problem of FAPI is its complication.
OAuth and OpenID Connect themselves are already complicated standard, but FAPI is the extension of them.
So at this point, Android developers involving in Fintech services need to implement by themselves with the clear understanding of requirements in FAPI.
Through AppAuth, we will lean requirements in Here, implementation of FAPI in context of OAuth2.
Outline May change later 1.
Review of OAuth 2.
Understanding the implementation of OAuth2.

Safetynet Attestation vs Key Attestation 3.
In this talk, we will take a look at Flutter's reactive framework and a few reactive architectures which take advantage of Dart's async library.
From TensorFlow's earliest mobile app demo to TensorFlow Lite and Android Neural Networks API, we are witnessing how latest research e.
This year, with the beta release of ML Kit, we now have another powerful toolbox to leverage machine learning in the mobile application development.
This talk features a side project Magritte, an educational application that helps people learn foreign languages.
It's sort of like Duolingo but with eyes, the application recognizes daily objects using custom machine learning models embedded on device and speaks the vocabulary out loud with the chosen language.
By presenting the Magritte app, the talk will reveal how the models for TensorFlow mobile were initially trained and optimized, how the performance was improved with TensorFlow Lite and MobileNet models, and eventually the migration to ML Kit.
Intended AudienceAndroid developers who are interested in getting to know how to leverage machine learning power in their applications by running the inference with model on-device.
Our apps can run on smartphones, Chromebooks, TVs, cars, watches.
Where is my bottleneck?
You send it to the internal testing, your managers.
And they say it is slow!
We ran into the exact same situation and dug into the tools that may be used to make your Android app work on 60 frames per second.
This presentation is intended for the people who haven't dived into the UI performance yet.
You will see some examples of easy and fast ways to check if your app works well and if it is not, how to find the potential problem.
Developers who ran into the low-fps app problem who does not know how to start and what to measure.
Mainly, Android apps can be divided into two categories: Activity-based or a Single Activity and some variations, as usual.
What unites them - need for navigation from screen to screen.
In this talk, I would like present you a lightweight solution of the complicated problem.
In this talk, we will discuss: The problem of screen navigation in Android Common solutions and their drawbacks Ready frameworks Conductor, Flow, Architecture Components Navigation and why they don't fit any project Qualities we want to achieve and how Cicerone fulfills them Decisions that were made while designing the library How to use it Common examples of building the navigation in case of using Drawer Menu or Bottom Navigation Panel.
Intended AudiencePeople who are tired from the complexities of the in-app and deep link in Android and are looking for a testable and maintainable solution for navigation problems.
Intended AudienceWorking in a startup environment requires to respond and adapt to market and user needs quickly.
Users usually do not know what they want and the market provides many hidden opportunities.
The issue is only to discover them and apply.
Moreover, it is not that easy: how would you know if users want that fancy feature, which you have been developing for the last month?
How would we answer the question if the feature is valuable and everybody just stays in queue shouting, "take my money"?
Lean startup approach suggests testing everything.
It is a well-known methodology and is heavily used nowadays for many digital products.
We will go through the couple of successful tests we did and share some results.
Thread is an IPv6 based low-power mesh networking technology for IoT products, intended to be secure and future proof.
Thread is running over 6LoWPAN, which is natively supported by Android Things.
This talk will be an introduction to LoWPAN APIs and the Thread network protocol, and it is especially targetted for the curious who have never heard about those technologies yet, but wish to know more about those through easy-to-understand explanations and demos.
I would like to share how unidirectional data flow can be achieved in Android.
In this session I will try to explain: What is unidirectional data flow and the core concepts behind it.
The concepts of Action read article State: - Actions: Immutable payload that describe updates to State.
Using ViewModel to: - Receives Action from View.
Benefit of using Unidirectional data flow - Testability - Predictability - Traceability - Debugging and Replay - etc Intended AudienceAndroid developers with prior knowledge of: - Android Architecture Components, ViewModel and LiveData.
You can: - Implement clear and concise data flow, and - Adapt the pattern to your use case.
Flutter's getting to attract mobile developers' attention, especially Android Developers, and some already have released applications.
When you consider if you can use キャッシュフローボードゲーム無料apk in production, there should be many things to check.
I'll talk about what I can give for your technical decisions.
Topics are supposed to be the following.
Answer: All of these components owe key functionality to the Android Transform API.
It is a centerpiece of the Android Gradle Plugin's internal architecutre, as it is responsible for processing intermediary build artifacts, and before the introduction of D8, it was even tasked with the bytecode transformation of Java 8 code for Android as well.
To third-party developers, it offers a hook into the creation of an APK through a centralized concept, the Transform, which can inspect and modify classes or resources.
Little documentation and a lack of accessibility to the topic have rendered the Transform API a "hidden gem" in the Android plugin infrastructure.
This talk will explore the Transform API, and introduce the required steps to register a custom transformation for a given scope to the audience, in a live coding session.
Intended AudienceAttendees are expected to be familiar with the concept of a Gradle plugin, however they do not need to have prior experience writing a plugin themselves.
With the advent of its release in 2016, a powerful model for writing test extensions was introduced, allowing for the augmentation of tests with new functionality.
What used to be RunWith and Rule, has now matured into a much more versatile tool for developers.
This talk will demonstrate and explore the capabilities of the JUnit 5 Extension Model.
Listeners will learn to appreciate the ExtensionPoint API based on concrete examples, including: - Hooking into the test lifecycle; - Providing test method arguments through a ParameterResolver; - Test instance post processing Intended AudienceAs this is not an introductory talk to testing, listeners are expected to be familiar with the core concepts of unit testing in general.
However, prior knowledge of JUnit 5 in particular is not required, since the relevant API is introduced as it becomes necessary throughout the talk.
However, in team development, it is difficult to follow along because the master branch frequently changes.
If you add the new feature as it is to existing screen without testing, it will be easy to degrade.
In this talk, I will explain how to キャッシュフローボードゲーム無料apk the code under development to master at any time so as not to affect the existing function by using the feature flag.
Also, I will explain how to make the new code a testable and switchable by separating it from the existing code.
But what about the middle size team with 10 to 20 engineers?
Intended AudienceDid you ask yourself how to keep a good pace reviewing pull requests and getting click to see more merged quickly?
How not to have many conflicts with each other?
How to have a good test coverage with instrumentation tests and run them fast?
How to have app releases constantly and not spending hours on it?
I can assume that at least one question popped up once in a while.
I this talk I would like to share our experience with CI and CD and how we have effectively adapted it to our needs.
The topic will include proper setup of CI for assembling builds and running tests, speed up integration tests using 3rd party tools and automated merging process.
An additional interesting subject would be how we have achieved releasing an app update every week just in 2 clicks.
So, キャッシュフローボードゲーム無料apk the end developers are focused most of the time on product needs and have all routine automated.
This talk will be useful for engineers who are planning to scale their teams and improve development and release setup.
Join my talk if you want to reach a new level of performance of your team.
It is a well known language with very good tooling, but it also has a lot of pitfalls.
For one, it is a very complex language.
It also makes it really easy to accidentally introduce memory leaks or segmentation faults; especially if you're used to automatic memory management via a GC Kotlin or Arc Swift.
It also looks quite different from modern language like Swift or Kotlin.
Now that we iOS developers got mostly rid of Objective-C, and Android Developers got mostly スターゲーム送料 of Java, it feels archaic having to go back to a language with an archaic Syntax like C++.
Rust looks and feels a lot like Kotlin or Swift, and it offers the same easy ways of sharing code as C++.
In addition to that, Rust has a very safe memory management model, high performance, a way to do fearless concurrency, and a very rich package ecosystem.
As a bonus, it compiles to WebAssembly, so the shared code could also be used in any HTML5 app.
This talk showcases how one can share very performant cross platform code between iOS, Android and others by using Rust.
Intended AudiencePeople interested in sharing code cross platform.
People interested in Rust, people that don't want to use C++.
I'll talk about the security-aware implementation of Android app in Kyash where I'm working for.
Ex The way to detect the falsification of the app, the important points for API network call.
I'm using DataBinding a lot in Kyash Inc where I'm working for.
I know DataBinding has both pros and cons, you may not like it because of some cons.
I'll talk about its pros and cons, why I love it, how it changes our development style, and the useful Custom Binding Adapters which I'm using in Kyash Inc.
Even after you have written them, they can take too long to run.
As deadlines approach, we often skip testing in order to write code faster.
How can we make our tests better?
What if UI tests were easier to write?
What if they actually helped us develop faster?
At Simple we've architected our application and UI tests so that it's easy to do most development even while offline.
This also lets us start new features before the backend services are finished.
It's the new kid in the block and offers you a native cross-platform development environment.
We'll explore the market of these late adopters of Android smartphones and the conditions that differentiates them from most of our current target audience Data affordability, Device affordability and Linguistic barriers.
We'll review the different steps taken by Google in click at this page down the barriers including the introduction of Android Go.
We'll discuss what Android Go is, why it was made, what changes it brings and its intended impact.
We'll also cover the differences between Android Oreo Go and Android One and the impact of Android One so far since it's launch.
I'd also like to share a few experiences of mine while building Gramseva: Kisan, an app for farmers to inform them of the latest agricultural commodity prices, help them decide whether to stock or sell their produce, help them bargain with vendors and offer them an easy way to share and access this information at all times.
I also had a chance to interview a few farmers from a village in Kalchinna, Uttar Pradesh, India and hope to share my experiences with them.
Then we'll look into a few steps we can take in building apps that are conscious of battery, memory, connectivity, localization and performance.
The many considerations that developers need to take care while building apps for these smartphones and how the little things can make a difference.
We'll explore tools we can use to profile our apps, simulate bad network connections and eventually optimize our apps.
Alongside that, we'll also explore how to build Android Go compliant apps.
Intended AudienceDevelopers, Entrepreneurs and the like looking to build applications for farmers or late adopters of Android smartphones due to barriers in network connectivity, device affordability and linguistic barriers.
Today, you'll seldom find an app without AppCompat, Retrofit, or RecyclerView.
But how do these libraries actually work?
This ジミーは世界の大きなカジノカバーを食べる will focus on some of the interesting internals that make some of our favorite libraries work.
Intended AudiencePrerequisite knowledge: how to write Android apps.
Challenges the session aims to resolve: an explanation and understanding of how these libraries we all use actually work under the hood.
Not only because of the huge eco-system many device resolutions and hardware variantsbut also the nature of Media playback itself: codec, media standard, drm, performance, etc.
ExoPlayer made by Google is an elegant solution for many years.
I address this request as the main concern of this talk, as well as discuss about related problems one may faces while solving them.
The talk will be tentatively organized as follow: - Quick intro about how Media playback is, in 2018.
Intended AudiencePeople who are interested in Media playback in Android, or RecyclerView, or both.
This talk will cover a plethora of command line tips and tricks along with real world examples of how mastering the command line can save us valuable time as developers.
Intended AudienceAll Android developers.
Commonly known as internationalisation i18na lot of people underestimate the impact that getting it wrong can have for your users as well as your systems.
Drawn from experiences with working on a global network of backend systems, websites and mobile apps in more than 30 locales for the last 10 years, this talk will start with an introduction to the concepts behind timezones and locales.
Technical topics covered are: - How does the JVM deal with timezones and locales and in which way is this is handled differently on Android devices?
We have to support daylight-savings-time?
Or you might think about a subscription model to create an ongoing cashflow by selling a service.
Depending on your actual type of projects in the Android-ecosystem you might never had the need to look into monetisation of an app.
Well, at least until Google starts their next round of product consolidation and renaming anyway.
Part of this will be understanding what the differences between purchases and subscriptions are and how to specifically cater for subscription events such as cancellations, recurring billings and trial periods using a server-to-server API provided by Google.
We will also have a look at source libraries, such as billingx or Register and see how they might be able to make your lives easier.
Another big topic is managing your in-app products in Google Play.
Approaching this setup from the wrong end might lead to a massive chain of follow-on work with regards to managing international pricing and product descriptions across a plethora of languages.
An easy way to measure your success is provided by Firebase Analytics.
Intended AudienceIntermediate-level, developers with 2-3 years+ experience.
Learn how it is build under the hood and how you can use it to improve and scale your testing infrastructure in a cost effective way.
Description: Flutter is an open-source mobile application development SDK created by Google.
It is used to develop applications for Android and iOS by coding just once in Dart and deploying to both of these platforms.
The app it produces is a treat for the eyes as everything is drawn right on the screen, pixel perfect!
I got that covered in this talk for you along with the following takeaways: Why coding twice is not productive anymore?
In this talk, you'll learn about AGP internals and answer questions like: -What's D8 and R8?
You'll come away with a better understanding of the toolchain which will make you a better equipped Android developer!
Intended AudienceAndroid users who use Gradle as their build system.
We will show how common code is run, do it can access native platform APIs, and how to configure the project to be compatible.
If you have answered yes to at least one of the questions above, I have a solution for you.
Join this talk and fall again in love with unit testing.
