title: Android findViewById in service
body: <p>I am doing something like when a service get started, a custom toast notification shows up.</p>
  
  <p>The custom toast view is defined in a xml file, the problem is that <code>findViewById</code> is not available in Service class.</p>
  
  <p>Since it's a bad idea to start an activity in a service. So, how can i solve this problem ? </p>
