  <pre><code>public class ContactsPickerActivity extends AppCompatActivity implements OnContactSelectedListener {
  public static final String SELECTED_CONTACT_ID  = "contact_id";
  public static final String KEY_PHONE_NUMBER     = "phone_number";
  public static final String KEY_CONTACT_NAME     = "contact_name";
  
  
  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_contacts);
  
      FragmentManager         fragmentManager     = this.getSupportFragmentManager();
      FragmentTransaction     fragmentTransaction = fragmentManager.beginTransaction();
      ContactsListFragment fragment           = new ContactsListFragment();
  
      fragmentTransaction.replace(R.id.fragment_container, fragment);
      fragmentTransaction.commit();
  
      ActionBar actionBar = getSupportActionBar();
      if (actionBar != null) {
          actionBar.setDisplayHomeAsUpEnabled(true);
          actionBar.setTitle("Select contact");
      }
  }
  
  
  @Override
  public void onContactNameSelected(long contactId) {
      /* Now that we know which Contact was selected we can go to the details fragment */
  
      Fragment    detailsFragment = new ContactDetailsFragment();
      Bundle      args            = new Bundle();
      args.putLong(ContactsPickerActivity.SELECTED_CONTACT_ID, contactId);
      detailsFragment.setArguments(args);
      FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
  
      transaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
      // Replace whatever is in the fragment_container view with this fragment,
      // and add the transaction to the back stack
      transaction.replace(R.id.fragment_container, detailsFragment);
  
      transaction.addToBackStack(null);
      // Commit the transaction
      transaction.commit();
  }
  
  /**
   * Callback when the contact number is selected from the contact details view 
   * Sets the activity result with the contact information and finishes
   */
  @Override
  public void onContactNumberSelected(String contactNumber, String contactName) {
      Intent intent = new Intent();
      intent.putExtra(KEY_PHONE_NUMBER, contactNumber);
      intent.putExtra(KEY_CONTACT_NAME, contactName);
  
      setResult(RESULT_OK, intent);
      finish();
  }
