This page about the Android Emulator, gives you a lot of tips on how to do different things in you emulator, like rotate the screen of your AVD device.
Heres some of the things I find quite useful when working on my apps:
From the Controlling the Emulator section:
| Emulated Device Key | Keyboard Key |
| Switch to previous layout orientation (for example, portrait, landscape) | Ctrl-F11 |
| Switch to next layout orientation (for example, portrait, landscape) | Ctrl-F12 |
| Home | HOME |
| Toggle cell networking on/off | F8 |
Theres also a Chapter on Networking that will help you if you are developing any apps that use network.
- You can for example use you localhost to test different things.
- You can also set delay and speed settings for your device, to simulate slow networks.
- You can simulate the use of GPS, send SMS and more.
