title: How to send a push notification from one Worklight-based Hybrid app to another Worklight-based Hybrid app
body: <p>I run Push Notification Sample code on Worklight server and its working. 
  Now i want to send notification from one device to another device so what are the required changes in the adapter?</p>
  
  <p>The adapter XML:</p>
  
  <pre><code>&lt;displayName&gt;PushAdapter&lt;/displayName&gt;
  &lt;description&gt;PushAdapter&lt;/description&gt;
  &lt;connectivity&gt;
      &lt;connectionPolicy xsi:type="http:HTTPConnectionPolicyType"&gt;
          &lt;protocol&gt;http&lt;/protocol&gt;
          &lt;domain&gt;https://android.apis.google.com&lt;/domain&gt;
          &lt;port&gt;8080&lt;/port&gt;           
      &lt;/connectionPolicy&gt;
      &lt;loadConstraints maxConcurrentConnectionsPerNode="2"/&gt;
  &lt;/connectivity&gt;
  </code></pre>
  
  <p>Should i change domain and port and i have to upload the app first on google play so that i can able to recive or send notifications. And should i create a key for android device on GCM </p>
