The emulator starts up fine. But when you long-press the power button (or F7) and choose "Power off", it displays a "Shutting down" message which remains on-screen forever and the emulator won't actually shut down.
I can close the emulator window or kill its process. But I'm wondering if this is the correct way to shut down an Android emulator.
According to the documentation I found at google, simply closing the emulator window is the correct way to shut the emulator down.
To stop an emulator instance, just close the emulator's window.
