cannot kill adb.exe manually
<p>After android studio running several hrs,suddenly the connected device shows as offline.And what's annoying is that it always show an offline device no matter connecting or not by usb.</p>

<p>As what we always do, I try to call <code>adb kill-server</code> or <code>adb start-server</code>.From the process list, it shows an new <code>adb.exe</code> was created while the former one wont disappear even  i try to stop it from the list.</p>

<p>So far my only solution is restart pc, i mean, FORCE restart.Normal stop or restart will keep my pc in the stopping screen.</p>

<p>Hope someone facing the same issues can support a better solution.Thanks anyway.</p>
