title: Android & IOS - Send notification between devices
body: <p>I've got a new requirement from the client that he would like to receive and send notifications between two applications and platform.</p>
  
  <p>For example let's say we are similar to the Uber application and I've got two different apps, one for the customer and the other one for the driver.</p>
  
  <p>If the customer sends a request to the nearest driver, the driver will receive a new notification that describes the pickup time and more info. The same thing will happen to the customer. </p>
  
  <p>When the driver picks up the request or declines it, the customer will receive a notification showing the status of the request.</p>
  
  <p>Another thing that I would like to add, is a broadcast notification for all users. Since we have an admin for the system, the admin would like to send a broadcast message for all users, something like an announcement for new updates, offers and so on.</p>
  
  <p>What is the best approach for doing that, even if I should implement another server using Java, NodeJs.</p>
  
  <p>But I need a good solution, plus good tutorials if available.</p>
  
  <p>Thanks</p>
