title: Notify when user is in my location in Android
body: <p>I am looking for an easy way to check if a user is at my location (50m) radius if notify me.</p>
  
  <p>Right now I have a service running every two minutes getting position of each user comparing it and then notifying if user in same location.</p>
  
  <p>Can this be done using promixityalert: <a href="http://goo.gl/9I857T" rel="nofollow">http://goo.gl/9I857T</a>?</p>
  
  <p>Thanks!</p>
