title: How do I clear notifications using ADB shell
body: <p>I know I can unlock the screen, pull down the notifications, and press the clear notifications button, but there's got to be a way to clear the notifications through <code>ADB</code>, right? I'm guessing it's some <code>Intent</code> sent through the 'am' command, or maybe something even simpler, but I can't seem to find anything on the net. All I'm getting is <code>Java</code> code for use with an <code>apk</code>.</p>
  
  <p>Edit: I should probably mention that I'm running on 4.3, sometimes commands may vary between versions.</p>
