How can i get Input Keyevent return value?
<p>How can i know if <strong>input key-event command</strong> succeeded or not?</p>

<p>Like if i run <code>adb shell input keyevent 3</code> how can i know that it succeed?
I tried to write this command and look in <strong>dmesg</strong> and <strong>logcat</strong> logs but there no indication about it.</p>
