title: change android dialer by intent
body: <p>Want to implement own <code>dialer</code> <code>activity</code>, but don't know how to show <code>chooser</code>, where user can choose my app as <code>dialer</code>. Found billions link how to catch calls or open <code>chooser</code> like this: <a href="https://stackoverflow.com/questions/23211795/make-call-in-android-application-using-default-call-application">link</a></p>
  
  <p>But this not fits to me. Need only to show chooser dialer dialog without make call after choose. Just only choose default dialer. Is it real? Will be glad any link or proposals. </p>
