What is the role of Android Runtime in the operation of Android devices?

Android Runtime (ART) is the environment for running applications on Android, responsible for launching and managing the application's lifecycle. ART replaced Dalvik starting from Android 5.0 and provides more efficient code execution.

Main functions of ART:

• Compiling Java bytecode into machine code (Ahead-Of-Time compilation) during app installation, which speeds up startup and performance.
• Memory management through garbage collection.
• Ensuring security and isolation of applications.

Thus, ART plays a key role in the performance and stability of Android devices, ensuring efficient application execution.
