ART stands for Android Runtime, which is the runtime environment used for running Android applications on Android devices. It was introduced in Android 4.4 (KitKat) as a replacement for the previous Dalvik runtime[1][2].
The key differences between ART and Dalvik are:
ART uses ahead-of-time (AOT) compilation, where apps are compiled when installed, while Dalvik used just-in-time (JIT) compilation[2].
AOT compilation makes apps launch faster and run more efficiently compared to JIT[2].
ART also performs additional optimizations to further improve performance[2].
ART requires more storage space on the device compared to Dalvik, as it stores the compiled native code[2].
