title: Android Communication between Broadcast Receiver and MainActivity (Send data to activity)
body: <p>I've a simple Main Activity which has to stop till an SMS is received... How can I launch a method from the <code>MainActivity</code> within the <code>BroadcastReceiver</code>'s <code>onReceive()</code> Method?</p>
  
  <p>Is there away with Signal and Wait? Can I pass something with a pending <code>Intent</code>, or how can I implement this communication?</p>
