title: Event listener in a broadcast receiver?
body: <p>So, this is probably a very basic design question, but Im just not sure how to go about it.</p>
  
  <p>Normally, when I use event listeners, I define it in whatever class, then I override the necessary methods in my Activity and instantiate the class and the listener as needed. </p>
  
  <p>However, in this case, I have my MainActivity class (that also implements the listener), a class (called testClass) that implements the listener, and a broadcast receiver class. The broadcast receiver class instantiates the calls  the testClass. Now, what I am trying to do is to update a TextView in MainActivity when a given function is called in the  testClass. </p>
  
  <p>Not sure how to go about this. </p>
  
  <p>Hope this wobbly issue description makes sense. </p>
