What is the main function of the Dalvik virtual machine in Android devices?

The Dalvik virtual machine on Android devices is used to run applications written in Java, but with features optimized for mobile devices. It converts Java bytecode into its own format (DEX) and executes it, ensuring efficient use of memory and CPU resources on resource-constrained devices. The main function of Dalvik is to provide isolation and manage application execution, as well as optimize performance and energy consumption.
