In our previous post, we explored how to leverage Firebase AI Logic to build cloud-hosted and hybrid AI features. Traditional mobile UIs excel at focused, hands-on tasks, and the Android intelligence system is introducing complementary features to make complex, multi-step actions even easier. By supplementing traditional user interfaces, AppFunctions provide a powerful new entry point: A privileged agent on the device can access app features in the background. This can be particularly helpful when users are driving, walking or otherwise multitasking. In this article, we'll show you how we designed and integrated these capabilities into our travel planning app, JetPacker, using Android AppFunctions. We'll explore the rationale behind our feature choices, discuss the specialized tooling we used to accelerate development, and dive into the code that makes it all work. Designing AI-ready features: making choices that matter for your users To select which features to provide to the intelligence system, we looked for tasks where a voice or text command is objectively faster than tapping through screens. In this side-by-side screen recording you can see this contrast perfectly: on the left, a user tapping through multiple screens to log an expense; on the right, the same task completed instantly in the background via a privileged agent. Our first choice was expense tracking. Logging a coffee expense during a trip usually takes quite a few taps--unlocking the phone, opening the app, finding the active trip, navigating to the expenses tab, tapping the add button, taking a picture of the receipt, and checking the result. By providing the addExpense and getExpenses features as AppFunctions, the system agent handles th ## On-Device Debugging And JUnit 5 DevFeed: [On-Device Debugging And JUnit 5]() Original publisher: [Read original article]() Author: Shai Almog Published: 2026-05-30T00:00:00Z Content type: tutorial Language: en Sources: [CodeName One]() Topics: [debugging](), [IntelliJ IDEA](), [Android](), [iOS](), [ide](), [simulator](), [Tooling](), [Code](), [Emulator](), [SDK](), [Visual Studio Code]() Tags: [android](), [android-apps](), [android-studio](), [apk](), [app](), [breakpoint](), [build](), [code](), [debugging](), [developer](), [emulator](), [ide](), [intellij](), [intellij-idea](), [ios](), [java](), [junit](), [linux](), [on-device](), [simulator]() ### AI overview This tutorial describes Codename One's new JDWP-based on-device debugging for ParparVM iOS and Android apps.

This includes the start of Android 16's rollout, with details for both developers and users, a Developer Preview for enhanced Android desktop experiences with connected displays, and updates for Android users across Google apps and more, plus the June Pixel Drop. We're also recapping all the Google I/O updates for Android developers focused on building excellent, adaptive Android apps. With new form factors emerging continually, the Android ecosystem is more dynamic than ever. From phones and foldables to tablets, Chromebooks, TVs, cars, Wear and XR, Android users expect their apps to run seamlessly across an increasingly diverse range of form factors. Yet, many Android apps fall short of these expectations as they are built with UI constraints such as being locked to a single orientation or restricted in resizability. With this in mind, Android 16 introduced API changes for apps targeting SDK level 36 to ignore orientation and resizability restrictions starting with large screen devices, shifting toward a unified model where adaptive apps are the norm. This is the moment to move ahead. Adaptive apps aren't just the future of Android, they're the expectation for your app to stand out across Android form factors. Why you should prioritize adaptive nowSource: internal Google data Prioritizing optimizations to make your app adaptive isn't just about keeping up with the orientation and resizability API changes in Android 16 for apps targeting SDK 36. Adaptive apps unlock tangible benefits across user experience, development efficiency, and market reach. Mobile apps can now reach users on over 500 million active large screen devices: Mobile apps run on foldables, tablets, Chromebooks, and even compatible cars, with minimal changes. Android 16 will introduce significant advancements i ## Understanding Dispatchers: Main and Main.immediate DevFeed: [Understanding Dispatchers: Main and Main.immediate]() Original publisher: [Read original article]() Author: Shreyas Patil Published: 2025-04-02T12:22:06Z Content type: tutorial Language: en Sources: [Shreyas Patil's Blog]() Topics: [Coroutines](), [kotlin-coroutines](), [Kotlin](), [Android](), [Programming]() Tags: [android](), [android-app-development](), [android-apps](), [android-studio](), [coroutine](), [coroutines](), [coroutines-flow](), [kotlin](), [kotlin-beginner](), [kotlin-coroutines](), [kotlin-multiplatform](), [main-thread](), [multithreading](), [reactive-programming](), [threadpools](), [threads]() ### AI overview A deep dive into Kotlin coroutine dispatchers on Android, explaining the difference between Dispatchers.Main and Dispatchers.Main.immediate.

It explains how Android UI development evolved from findViewById and Butter Knife to Kotlin synthetics, ViewBinding, and DataBinding, and frames Compose as a response to increasing UI complexity and UX requirements. ### Source excerpt The development of Android mobile apps is nothing new. We have been doing it since 2009, when the Android SDK was published. In the meantime, many APIs used for developing Android mobile apps were updated, but the general idea of app development remained. Looking at something as basic as accessing the UI elements and modifying them, we can see the constant need for improvement and change. We've started with findViewById, then we transferred to Butter Knife library. After we switched from Java to Kotlin, we were introduced to Kotlin synthetics, then it went deprecated soon enough, and it was replaced by ViewBinding. In the meantime, we also received a new support library, DataBinding, that enabled us to bind our UI components to data sources from our app. As we can see, even though the final goal was the same (accessing UI elements defined inside XML and modifying their values), the APIs for reaching our goal were changed quite drastically and quite often. Why so many changes? The constant need for polishing the UX of ours apps introduced a lot more complexity in our mobile app projects. Designers demand more and more from their developers, and developers constantly strive for making their code as flexible and reusable as possible. This is something that gets harder and harder to accomplish when your base is not particularly designed for handling new types of designers requirements. Motivation To better learn something new, we need to understand the differences between what we know (Android View System) and the new things that are introduced by the new system (Jetpack Compose). Sometimes this feels overwhelming, because at the beginning, most of it looks like magic as we don't know anything about it. By familiarizing ourselves with Jetpack Compose way of working, we are putting ourselves in a better position to utilize this new tool. Android View System The base for developing Android apps most of us are currently using is Android View System. It is here since 2009 a ## How OkCredit Android App boosted Network Performance by 30% DevFeed: [How OkCredit Android App boosted Network Performance by 30%]() Original publisher: [Read original article]() Author: Shrey Garg Published: 2022-07-07T11:29:22Z Content type: tutorial Language: en Sources: [OkCredit - Medium]() Topics: [Mobile](), [Android](), [android-apps](), [Instrumentation](), [Network](), [Latency](), [HTTP](), [TLS handshake]() Tags: [android](), [android-app-development](), [android-apps](), [engineering](), [http](), [instrumentation](), [latency](), [mobile-app-development](), [network](), [okcredit](), [performance](), [tls-handshake](), [user-experience]() ### AI overview This tutorial explains how to analyze and optimize each stage of network calls in Android apps, including call start, DNS resolution, TLS connection setup, request and response transfer, connection reuse, and call completion. It describes using OkHttp connection pooling and the EventListener class to instrument HTTP-call metrics such as quantity, size, and duration. ### Source excerpt Fast and reliable network communication is crucial for OkCredit mobile apps. Since the majority of our users belong to Tier-2/3 cities in India, flaky and unreliable network connection is one of the biggest challenges for us. In order to deliver a good user experience, our mobile apps need to have reliable and low-latency network connectivity. While most resources we found describe how we can improve the overall time (start-end) of a network call, this article attempts to take a deep dive and talk about each step and how we can instrument and optimise each step of a network call in android apps. Steps involved in a network callFig. Steps of a Network call. Ref -- https://square.github.io/okhttp/features/events1. Call start Called as soon as a call is enqueued or executed by a client. Ideally, this step should not consume any time unless there are any custom Interceptors added. 2. DNS Involves the DNS Resolver translating the domain name into the corresponding identifier (the IP address). 3. Connection Start Tries to acquire a secure connection (TLS handshake) between the client and the server. 4. Connection End / Acquired Invoked after a connection has been acquired for the call. After this, the communication of request and response payloads is started. 5. Request / Response / Headers This is the step in which the actual communication of data happens. The HTTP method, size of request / response payload, server latency / response time, etc. can greatly impact the time taken by this step. 6. Connection released Invoked after a connection has been released for the call. 7. Call end Invoked immediately after a call has completely ended. Pooled connection OkHttp has the capability to pool connections with which it can skip various steps of a network call mentioned above, which in turn can greatly improve the application's network performance, as existing connections can be reused. Fig. Steps of a Network call with pooled connectionInstrumentation of each step To determine ## Coroutines on Android DevFeed: [Coroutines on Android]() Original publisher: [Read original article]() Author: Stevan Milovanovic Published: 2022-05-20T12:36:23Z Content type: tutorial Language: en Sources: [Homegate Engineering Blog - Medium]() Topics: [Coroutines](), [Android](), [async](), [Concurrent Programming](), [context]() Tags: [android](), [android-app-development](), [android-apps](), [article](), [async](), [asynchronous](), [cancellation](), [coroutine](), [coroutine-testing](), [coroutines](), [dispatcher](), [kotlin-coroutines](), [lifecycle](), [programming](), [thread](), [threads]() ### AI overview This tutorial explains why Kotlin coroutines can be preferable to threads for asynchronous and background processing on Android. It introduces coroutine scopes, contexts, suspending functions, jobs, and dispatchers, and describes using coroutines for networking and background processing. ### Source excerpt Coroutines on Android In this article I'll try to explain why coroutines are useful and why would you want to use them in your project. After we go through the most important concepts of coroutines, I'll show you how I used coroutines to implement networking and background processing in the example project. First of all, you might ask yourself, why we want to use coroutines over threads? Main problem with threads is that they are resource intensive, meaning it takes a lot of resources to start a thread, stop a thread. Meanwhile, coroutines are lightweight threads, since they use thread pools. Another benefit of coroutines is that they greatly simplify asynchronous code. Callbacks and synchronisation are very easy to use. In fact, they make parallel programming look very much like sequential programming. Coroutines can be paused and resumed at any time, on a number of threads. And lastly, since coroutines are based on a few fairly easy to grasp concepts, their syntax is simple and easy to use. Here are the main concepts we need to explain about coroutines: Scope Coroutine scope, as its name says, defines a scope for new coroutines. Every coroutine builder (like launch and async) is an extension on CoroutineScope and inherits its coroutineContext to automatically propagate all its elements and cancellation. Context Coroutine context represents the context of its scope. Context is encapsulated by the scope and used for implementation of coroutine builders that are extensions on the scope. Scope provides a context in which the coroutine runs (state of the coroutine which provides variables, functionality of the coroutine etc.). Suspending functions Suspending functions are functions that can be run in a coroutine. They make callbacks seamless.
