Android 2.0 relies on the Dalvik Virtual Machine. Unlike the host JVM, Dalvik uses a register-based architecture. Within the emulator, the DVM runs as a guest process. The emulator does not emulate the DVM itself (which is software); rather, it emulates the underlying Linux kernel and hardware upon which the DVM relies.
The Android 2.0 emulator came with several notable features that made it a popular choice among developers: android 2.0 emulator

Pressing the Menu button in your app wasn't an option; it was the primary way users discovered functionality.
