Hi
       You can use key codes directly like
    adb shell input keyevent 7    # for key '0'
    adb shell input keyevent 8    # for key '1'
    adb shell input keyevent 29    # for key 'A'
    adb shell input keyevent 54    # for key 'B'
we can also send string as a text, like
    adb shell input text "ANDROID"

The below text is the whole list of all keyevent names with their
respective codes numbers...
