By the way  if you are trying to find a way to send double quotes to the device  try the following      adb shell input text        I m not sure why there s no event code for quotes  but this workaround does the job  Also  if you re using MonkeyDevice  or ChimpChat  you should test each caracter before invoking monkeyDevice type  otherwise you get nothing when you try to send

One other difference     adb shell input  is calling the input jar to process and send the keycode from the Java layer of the android framework   adb sendevent  is actually c code  part of toolbox utility   that sends the input code directly into the  dev input     of Linux input subsystem    More detail code trace into inside AOSP Framework can be found here   http   www srcmap org sd share 4 aba57bc6 AOSP adb shell input Code Trace html RefId 7c8f5285

Also  if you want to send embedded spaces with the input command  use  s adb shell input text  this sis san sexample      will yield  this is an example  being input    itself does not need escaping - only the special  s pair is treated specially  This leads of course to the obvious question of how to enter the literal string  s  which you would have to do with two separate commands
