In a recent blog post, Google unwrapped some exciting achievements of the Android Runtime (ART) compiler. It detailed every bit of the ART journey, and how it improved the Android performance since the launch of Android 12. The developers shared some insights about the present system and even shared some glimpses of the future possibilities with ART 14.

Must See: Google to turn ART into Mainline module with Android 12 for quicker system updates

Android Runtime improves the updates and enhances the ability of manufacturers and Google developers to publish new compiler optimization through Google Play System updates rather than the OTA updates. Further, it improves the ability to push out upstream OpenJDL fixes more swiftly. It even helps to deliver faster updates to OpenJDK core language and fixes runtime and compiler security issues rapidly.

Apart from the above developer-based improvements, the ART results in faster app startup times, execution, and improved memory usage. In statistics, the app startup time is improved by up to 30% on some devices.

The ART Apex module further magnifies the ART benefits. “The ART APEX module is a complex piece of software with an order of magnitude more APIs than any other APEX module. It also backs a quarter of the developer APIs available in the Android SDK. In addition, ART has a compiler that aims to make the most of the underlying hardware by generating chipset-specific instructions, such as Arm SVE.”

It offers quite a strict testing process, that involves “compiling over 18 million APKs and running app compatibility tests, and startup, performance, and memory benchmarks on a variety of Android devices that replicate the diversity of our ecosystem as closely as possible.”

Following such a success with the ART 13 compiler, Google is inching towards the launch of ART 14 which is expected to carry some big improvements. It will bring “new compiler and runtime optimizations that improve performance while reducing code size,” and will support OpenJDK 17.

Some other changes are also making debut with the Android 14. “Recently, for Android 14, we refactored the interface between the Package Manager, the service that determines how to install and update apps, and ART. This moves the OS boundary from the ART dex2oat command line to a well-defined interface that enables future optimizations, such as finer-grained control over the compilation mode.“

Such large scale changes will definately further enhance the performance and stability of the system and the apps on Android.

Google has been secretly working on its next-generation operating system called ‘Fuchsia OS’ since quite some time now but there has not been any official announcement from the company. While some reports indicate that it could replace Android, some reports suggest that it will be entirely different.

Earlier, it was rumored that the Fuchsia OS will be capable of running Android applications and now we have a confirmation for the same from Google. Spotted by 9to5Google, a new change in the Android Open Source Project confirms that Fuchsia will be capable of running Android apps using the Android Runtime.

Last month, two repositories related to the Fuchsia OS were added to the Android Open Source Project (AOSP) manifest. The first — “platform/prebuilts/fuchsia_sdk” contains a pre-built copy of the Fuchsia SDK, which would be used to create applications. The second — “device/google/fuchsia” appeared like a device that could be used by the Android Emulator to run Fuchsia.

This week, there was a change that was posted to Android’s Gerrit source code management system. The README.md file helps explain what the “device/google/fuchsia” repository is intended for. It says that Fuchsia will use a specially designed version of the Android Runtime (“ART” above) to run Android applications. This version of ART will be installable on any Fuchsia device using a .far file which is Fuchsia’s equivalent of Android’s APK.

Fuchsia OS is being created from the scratch to overcome certain limitations that Android presents. It should be able to work across a range of products including phones, laptops, and smart devices. It looks like the OS is being built to be more secure, better capable to understand voice interactions and look the same across devices.

A couple of months ago, it was reported that an Android smartphone from Huawei is being used for testing Fuchsia. The Chinese company has been working on making the upcoming OS run on Kirin 970-powered devices, starting with Honor Play.

Huawei has also become the first company outside of Google to make a major contribution to the upcoming open source OS project. However, this is not surprising given that Google and Huawei have worked together in the past.

The strategy of Google of making information available early and giving developers and users time to warm up to the change seems smart as it makes the transition process easier for users as well as developers. While it will be many more months before we see Fuchsia in the wild, we are expecting Google to official acknowledge Fuchsia OS sometime this year.
