title: How can I adb install an apk to multiple connected devices?
body: <p>I have 7 devices plugged into my development machine.</p>
  
  <p>Normally I do <code>adb install &lt;path to apk&gt;</code> and can install to just a single device.</p>
  
  <p>Now I would like to install my apk on all of my 7 connected devices. How can I do this in a single command? I'd like to run a script perhaps.</p>
