title: How can I hide/cancel the default incoming screen
body: <p>I am currently intercepting a call and forwarding it to my customized "oncallscreen" activity. However, before getting to my screen it will flash to the default "oncallscreen". How can I hide/cancel this screen so when receiving call I get only my customized screen.</p>
  
  <pre><code>@Override
  public void onReceive(Context context, Intent intent) {
      Bundle extras = intent.getExtras();
      if (extras != null) {
          String state = extras.getString(TelephonyManager.EXTRA_STATE);
          Log.w("DEBUG", state);
          if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
              String phoneNumber = extras
                      .getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
  </code></pre>
