title: Pass mobile number to Facebook AccountKitActivity
body: <p>I am using <a href="https://developers.facebook.com/docs/accountkit/android/" rel="nofollow noreferrer">Facebook account kit</a> to verify user mobile number. I have used below code,</p>
  
  <pre><code>final Intent intent = new Intent(MainActivity.this, AccountKitActivity.class);
      AccountKitConfiguration.AccountKitConfigurationBuilder configurationBuilder =
              new AccountKitConfiguration.AccountKitConfigurationBuilder(
                      LoginType.PHONE,
                      AccountKitActivity.ResponseType.TOKEN); // or .ResponseType.TOKEN
      // ... perform additional configuration ...
      intent.putExtra(
              AccountKitActivity.ACCOUNT_KIT_ACTIVITY_CONFIGURATION,
              configurationBuilder.build());
      startActivityForResult(intent, APP_REQUEST_CODE);
  </code></pre>
  
  <p>All is doing well. I want to pass user mobile number to AccountKit activity. Is it possible to make it work? How?
  Actually I want to prevent duplicate mobile verification using Account Kit, is there any other way?</p>
