title: Background service for android (Xamarin)
body: <p>I am currently using Xamarin to develop an android application.
  What is the best way to add an background service to my application. It must always run if the app is open or closed. And  it must interact with the application database without opening it. </p>
  
  <p>For example the application must check every 5 mins if it must send a notification this check is based on the data saved in the application itself  </p>
