The article explains that AI agents can now handle enough implementation, translation, testing, and review work to reduce the cost of maintaining separate platforms. It also notes the planned relocation or archival of Shopify's React Native libraries. ### Source excerpt Native is now the future of mobile at Shopify Shopify are moving from React Native back to separate Swift and Kotlin codebases for their native apps, for the exact reason you would expect: We decided to switch from native to React Native in 2020 for three reasons: Stop building the same features twice Allow developers to work across the stack Spend less time chasing feature parity and more time shipping value [...] Native still means building and maintaining software on two platforms, that cost has not disappeared. What changed is that agents can now do enough of the implementation, translation, testing, and review work that it's no longer the deciding factor it was in 2020. It's a well-written post, which gives full credit to React Native as a great platform for the six years they were using it. Shopify are the maintainers of three significant React Native libraries: react-native-skia, flash-list, and restyle. The first two are finding new homes; the third "has a smaller user base than our other libraries" and will be archived at the end of 2026.

On a Pixel 6 running Android 14, the changes made decoding a fixed blur hash into a 384x384 image up to 4.35 times faster; one optimization using direct character access and a lookup table improved performance by roughly 5%. ### Source excerpt BlurHash is a compact representation of placeholders for images. A blur hash is encoded as a short string that can be rendered to a bitmap at runtime to display a "blurry" version of the source image. The way it works remind me of how spherical harmonics are used in 3D rendering engines to efficiently encode irradiance. I recently remembered that I had been meaning to look at the Kotlin implementation of BlurHash to see if there was a way to make it faster. I looked up the KMP port and after a few changes, I was able to make decoding a blur hash up to 4.35x faster on a Pixel 6 running Android 14. For all the measurements mentioned in this article, I decoded a fixed blur hash to a 384x384 image. The original code took 24.4 ms to do this when running at full speed, and 41.5 ms when locking the CPU clocks. This is way too long considering the low resolution of the image. ## What's new in Android 14 for developers DevFeed: [What's new in Android 14 for developers]() Original publisher: [Read original article]() Author: Kirill Rozov Published: 2023-10-04T18:06:41Z Content type: article Language: en Sources: [Stories by Kirill Rozov on Medium]() Topics: [Android](), [navigation](), [Jetpack](), [Library]() Tags: [android](), [android-14](), [android-app-development](), [androiddev](), [deprecated](), [developers](), [jetpack](), [navigation](), [new-features](), [permissions](), [pixel8](), [sdk](), [vulnerabilities]() ### AI overview This article reviews Android 14 changes affecting application developers, including background execution and foreground service restrictions, Intent and BroadcastReceiver changes, Predictive Back Gesture animations, and restrictions on installing applications targeting SDK versions below 23. ### Source excerpt Android 14 is already here, so I took the documentation, experts' reviews, and other available resources to sort out all the important changes that will affect most application developers. Let's examine new restrictions on background mode, changes in Foreground Service, new restrictions on the work of Intent and BroadcastReceiver. In this release, we have many restrictions, but we've also got new features. Thanks for Mishaal Rahman for his articles about Android 14. I based the articles on them.Predictive Back Gesture in actionDemonstration of animation of using back navigation. Source Already in Android 13, we were warned that in the next version of Android, we should expect updates of the Back Gesture and Predictive Back Gesture with animation in the form of a preview screen where we will move. Animation for that preview is still not working. If you want it to work, you should activate it in the developer's settings. Demonstration of animation of using back navigation An example of your personal animation when doing the Back gesture Also, the ability to create personal transition animations inside the application was added. For that, a method handleOnBackProgressed() was added in OnBackPressedCallback. This method is called with the progress of the Back Gesture, as well as the handleOnBackPressed() and handleOnBackCancelled() methods, which are called at the end of the Back Gesture's animation and its cancellation, respectively. On the screen, you can see an example of implementing your custom animation using the Jetpack AppCompat 1.8.0 library. class MainActivity : AppCompatActivity() { override fun onCreate(savedInstanceState: Bundle?) { ... val box = findViewById(R.id.box) val screenWidth = Resources.getSystem().displayMetrics.widthPixels val maxXShift = (screenWidth / 20) val callback = object : OnBackPressedCallback( enabled = true ) { override fun handleOnBackProgressed( backEvent: BackEvent ) { when (backEvent.swipeEdge) { BackEvent.EDGE_LEFT -> box.t ## Android 14 blocks modification of system certificates, even as root DevFeed: [Android 14 blocks modification of system certificates, even as root]() Original publisher: [Read original article]() Author: HTTP Toolkit; Tim Perry Published: 2023-09-05T14:00:00Z Content type: article Language: en Sources: [HTTP Toolkit]() Topics: [Android](), [Security](), [TLS (Transport Layer Security)](), [API]() Tags: [android](), [android-14](), [api](), [certificates](), [interception](), [root](), [security](), [tls]() ### AI overview The article examines Android 14's tighter restrictions on modifying trusted certificate authorities, including on rooted devices, and the resulting challenges for developers, testers, and researchers. An update notes that multiple workarounds now allow certificate injection. ### Source excerpt Update: This post sparked a lot of excellent discussion and debate on workarounds, and there are now multiple working solutions to allow certificate injection on Android 14, despite the restrictions discussed here. See the update post for more details. When Android was initially announced in 2007 by the Open Handset Alliance (headed by Google) their flagship project was billed as an "open platform", "providing developers a new level of openness", and giving them "complete access to handset capabilities and tools". We've come a long way since then, steadily retreating from openness & user control of devices, and shifting towards a far more locked-down vendor-controlled world. The next step of Android's evolution is Android 14 (API v34, codename Upside-Down Cake) and it takes more steps down that path. In this new release, the restrictions around certificate authority (CA) certificates become significantly tighter, and appear to make it impossible to modify the set of trusted certificates at all, even on fully rooted devices. If you're an Android developer, tester, reverse engineer, or anybody else interested in directly controlling who your device trusts, this is going to create some new challenges. Before we get into the finer details, first I want to talk a little about the context around Android CA management and how we got here, but if you want to jump to the latest details you can go straight to the Enter Android 14 section below. "Open Software, Open Device, Open Ecosystem" While the initial principles of Android were very much focused on open software, controllable by users and developers, over more recent years Android has increasingly limited the control of users, developers & researchers over their own devices. The key turning point in this process was Android 7 (Nougat, released in 2016) in which the certificate authorities (CAs) on the device that were previously fully modifiable by the owner of the phone were split in two: one fixed list of CAs provided ## Regional Preferences in Android 14 DevFeed: [Regional Preferences in Android 14]() Original publisher: [Read original article]() Author: Alex Zhukovich Published: 2023-05-26T17:32:20Z Content type: tutorial Language: en Sources: [Alex Zhuk - Android development and testing]() Topics: [Android](), [API](), [data](), [App]() Tags: [android](), [android-14](), [api](), [app](), [article](), [data](), [how-to]() ### AI overview This tutorial explains how Android 14's Regional Preferences settings expose regional values such as temperature unit, first day of the week, hour cycle, and calendar type through an API. ### Source excerpt This article explains how to get access to values from a "Regional Preferences" settings screen in Android 14.
