- “Ctrl+F11” change the orientation of the emulator
- “F8” Turns networks on/off ]
The native GPU of the Computer can be used by the graphics of the emulator. This will make the rendering in the emulator very fast to enable this add the GPU Emulation property to the device configuration and set it to true.
You can also get the “Enabled” flag for the snapshot. This will save the state of the emulator and will let it start much faster. And native GPU rendering and snapshots do not work together currently.
Android 4.0 introduces devices that do not have hardware any more if you want to create such AVD add the Hardware “Back/Home keys” Property to the device configuration and set it to ‘false’.
