thank swarup for the insight

i was able to look at the events from emulator, the keycode i different than
defined in frameworks/base/core/java/android/view/KeyEvent.java

all i can say is keycode for emulator and real device maybe different.

and i am using SDK version: android-sdk-windows-1.1_r1

here is how to use: sendevent

command format: sendevent device type code value

[command] [device] [type] [code] [value]
sendevent /dev/input/event0 1 229 1

/dev/input/event0 is the device to send it to

[type] 1 is unknow for me ( maybe code for physical button on device )

[code] 229 is the MENU button of the emulator

[value] 1 is keydown or press down ( for keyup or up use 0 )

i wrote a batch file for sending the event to the device like below:

adb -s emulator-5554 shell sendevent /dev/input/event0 1 229 1
adb -s emulator-5554 shell sendevent /dev/input/event0 1 229 0

have to use the follow command to simulate a pressing of button ( aka
pressing down then let go )

Key Name CODE
MENU 229
HOME 102
BACK (back button) 158
CALL (call button) 231
END (end call button) 107

now keyboard shown on the emulator
