title: Sending notifications to a android phone via a web service
body: <p>I have an android application which collect accelerometer and microphone data. If those data satisfy a predefined condition, they should sends to a web service. Then all other android phones which a connected with this web service(phones which have the same application) can be received a notification automatically. But I have no idea about this notification sending part. What is the way to send notification to connected phones automatically.
  Thank you....!</p>
