Google reveals: ART independent update to speed up Android app startup

News on August 23, Google recently introduced in detail the latest advantages of the Android Runtime (ART) and the innovative capabilities of independent updates in its latest blog post. As the engine that drives the Android system, ART is responsible for the important task of compiling Java and Kotlin into bytecode and executing it. The most striking thing is that ART now has the ability to be updated independently of the operating system, which means that users will experience application performance improvements more quickly without waiting for the release of the complete operating system.

According to Google reports, with Android With the release of 13, ART has achieved up to 30% improvement in application launch speed on some devices. This is a significant leap forward in improving user experience. This performance improvement is due to ART becoming an Android A modular component within the 12 operating system, this allows ART to be independently updated through the Google Play Store without having to wait for the entire operating system release cycle.

At the same time, Google’s version control of ART has also attracted attention. With the release of Android 14, ART will usher in its corresponding "ART 14" version. This time, ART 14 isn't just limited to Android 14, most of the improvements will be pushed to older versions of the OS as well, meaning users won't need to upgrade to Android 14 can also benefit from ART's new features and performance improvements.

According to the editor’s understanding, the changes in ART in Android 13 are also worthy of attention. Google details ART 13 improvements, including improvements in native code switching speed and JNI calling speed. ART 13 Performing more bytecode verification during app installation, thereby reducing the burden of runtime verification, has resulted in a 30% reduction in app startup time on some devices.

In the future, updates to ART 14 will introduce more exciting changes. Google plans to upgrade Android from OpenJDK 11 to OpenJDK 17, which will also introduce new compiler and runtime optimizations to improve performance and reduce application code size. These initiatives will further promote the development of the Android ecosystem and bring users a faster and smoother application experience.
