title: Call an activity method from a BroadcastReceiver class
body: <p>I know I can do an inner receiver class to call any method from my receiver </p>
  
  <p>But my main activity is too damn big and does a lot of things. 
  So I will need a class that extends broadcast receiver but who isn't an inner class. And can call one method from my main activity. I don't know if it's possible but my activity is a Home activity and a "singleInstance" activity so maybe with this detail someone has a way to access to my activity.</p>
  
  <p>If it's impossible any way to split some java code in multiple files my main have more than 600 lines. (and for information I have already 19 java files for an alpha version of my apps so I have try to split it)</p>
