Delphi x Android Intents

I need help with my app. This app run in Sunmi Device and I would like a payment integration (another app).

My code for send intent its ok. But I need to receive an intent response.

Manifest:

<intent-filter>
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" />
    <data
        android:host="pay-response"
        android:scheme="scheme_return" />
</intent-filter>

Send intent:

uri :='payment-app://pay?return_scheme=scheme_return&amount=' + valorTotal + '&transaction_type=debit';

  Intent := TJIntent.JavaClass.init(TJIntent.JavaClass.ACTION_VIEW, TJnet_Uri.JavaClass.parse(StringToJString(TIdURI.URLEncode(uri))));
  SharedActivity.startActivity(Intent);

In my "uri" I have a return_scheme parameter. If the value of the parameter is the same as the manifest android:scheme="scheme_return", the payment is finished in the payment app, when my app return, the app is crashed (frozen).
If I change return_scheme parameter of any other value, when finished payment, my app open correctly.

I think the app is waiting on an intent response.
But how to get this answer?

--------EDIT---------

My code for receive intent:

    procedure TForm1.FormCreate(Sender: TObject);
var
  AppEventService: IFMXApplicationEventService;
begin
  if TPlatformServices.Current.SupportsPlatformService(IFMXApplicationEventService, AppEventService) then
    AppEventService.SetApplicationEventHandler(HandleAppEvent);

  MainActivity.registerIntentAction(TJIntent.JavaClass.ACTION_VIEW);
  TMessageManager.DefaultManager.SubscribeToMessage(TMessageReceivedNotification, HandleActivityMessage);
end;

procedure TForm1.HandleActivityMessage(const Sender: TObject; const M: TMessage);
begin
  if M is TMessageReceivedNotification then
    HandleIntentAction(TMessageReceivedNotification(M).Value);
end;

function TForm1.HandleAppEvent(AAppEvent: TApplicationEvent; AContext: TObject): Boolean;
var
  StartupIntent: JIntent;
begin
  Result := False;
  if AAppEvent = TApplicationEvent.BecameActive then
  begin
    StartupIntent := MainActivity.getIntent;
    if StartupIntent <> nil then
      HandleIntentAction(StartupIntent);
  end;
end;

function TForm1.HandleIntentAction(const Data: JIntent): Boolean;
var
  Extras: JBundle;
begin
  Result := False;
  if Data <> nil then
  begin
    Memo1.ClearContent;
    Extras := Data.getExtras;
    if Extras <> nil then
      Memo1.Text := JStringToString(Extras.getString(TJIntent.JavaClass.EXTRA_TEXT));
    Invalidate;
  end;
end;

After payment is finished, i received intent in HandleIntentAction, but always is nil.

First of all, take into consideration the following steps:

1. When you start the payment activity, use startActivityForResult instead of startActivity:

int PAYMENT_REQUEST_CODE = 123;
String uri = "payment-app://pay?return_scheme=scheme_return&amount=" + valorTotal + "&transaction_type=debit";
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
startActivityForResult(intent, PAYMENT_REQUEST_CODE); <--- Aqui

2. If possible, make sure that the payment app sends back the result correctly. It should set the result using setResult and call finish to close its activity:

// In the payment app's activity that handles the payment logic
Intent resultIntent = new Intent();
resultIntent.putExtra("status", "success"); // You can add any extra data if needed
setResult(RESULT_OK, resultIntent);
finish();

By using startActivityForResult and implementing onActivityResult, your app will be able to handle the response from the payment app appropriately.
I hope this helps.
