title: Appcelerator: There are no Android devices connected
body: <p><strong>In short:</strong> On Appcelerator I'm getting the message "<em>There are no Android devices connected</em>" and I'm not quite sure whether it's a bug or whether I neglected some step in the procedure. I've read everything I can find on the Web and in the Appcelerator help.</p>
  
  <p><strong>How I got here</strong>: I'm using Windows 8.1, and I'm a self-taught front-end guy who knows a bit of javascript-jquery-html-css-CMS-php.
  I was excited to hear about Appcelerator: I was promised that just by using Javascript you can create apps that match the ones written with native SDKs. </p>
  
  <p><strong>What's the problem:</strong></p>
  
  <ul>
  <li>I opened Hello World, got it to run on html, super.</li>
  <li>I downloaded the Android SDK here: <a href="http://docs.appcelerator.com/platform/latest/#!/guide/Installing_the_Android_SDK" rel="nofollow">http://docs.appcelerator.com/platform/latest/#!/guide/Installing_the_Android_SDK</a> and installed it. </li>
  <li>I have an Android Studio app in my Windows Start menu.</li>
  <li>I connected the Android environment, I have the  Android robot turned green with a check, great.</li>
  </ul>
  
  <p>When I launch Run on Android, I get the message "There are no Android devices connected"</p>
  
  <p><strong>What I did:</strong></p>
  
  <p>I went here: <a href="https://archive.appcelerator.com/question/160727/there-are-no-android-devices-connected" rel="nofollow">https://archive.appcelerator.com/question/160727/there-are-no-android-devices-connected</a> and did as suggested:</p>
  
  <ul>
  <li>adb kill-server</li>
  <li>adb start-server </li>
  </ul>
  
  <p>Got a message saying server started, but problem persists.</p>
  
  <p>I found something in the help about the Python Windows Installer<br>
  I installed python (<a href="https://www.python.org/downloads/windows/" rel="nofollow">https://www.python.org/downloads/windows/</a>) and launched the environment; but could not make out how this related to the problem at hand
  In the help (here: <a href="http://docs.appcelerator.com/platform/latest/#!/guide/Deploying_to_Android_devices" rel="nofollow">http://docs.appcelerator.com/platform/latest/#!/guide/Deploying_to_Android_devices</a>) I found a topic called "Deploying to Android devices" but it looks like theire talking about deploying to real Android devices ()For 2.x and 3.x Devices - For 4.x Devices).</p>
  
  <p>I read some people advising to change emulators or to check JRE versions, not sure whether this is relevant.</p>
