Android Emulator Keyboard not displaying
This is how to make emulator to show soft keyboard:
Device settings > Language and Input > Default > Hardware (Physical Keyboard) > set to Off
.
Press CTRL+F11 or num pad 7 to enable an onscreen keyboard within the OS. I don't think the 3.0 emulator has an equivalent keyboard interface the way the others do.
You can also issue a command from the keyboard. http://developer.android.com/guide/developing/tools/emulator.html
e.g.
Android == PC Keyboard
Back Key == ESC
Menu == Page-up
