title: How to Identify the Default App that Accepts Incoming Phone Calls in Android?
body: <p>I'm simply trying to find out which app is the default app to handle phone calls on my Android test device. Right now, I'm using the following code, this SHOULD work, but always returns null:</p>
  
  <pre><code>Intent phoneApp = new Intent(Intent.ACTION_ANSWER);
  
  ResolveInfo app = mPM.resolveActivity(phoneApp, PackageManager.MATCH_DEFAULT_ONLY);
  </code></pre>
  
  <p>Any ideas? It seems there is no documentation on this for some reason!</p>
