billing library 5.2.0 D11, Play billing Library 5.2.0

[toufik 2]

hello everyone a few days ago i did tried to implement a one time purchase (make a paid android app )
there is no error showing except the message that i will show you next 
thing i did consider: 
Make sure the product ID in your code matches the ID of the product you created in the Google Play Console.
Make sure that the product is published and active in the Google Play Console.
Make sure that the account you are using to test the app is not the same account you used to create the product in the Google Play Console.
i don't know what I'm missing i keep thinking that the new library is the problem (because its come with new change to how to implement purchase) 
i did publish the app in Internal testing. 

i did multiply approach and multiply attempt to fix this with no luck yet with the help of chat gpt .
ps : following this topic.

      const Products: TIAPProductList; const InvalidProductIDs: TStrings);
    procedure InAppPurchasePurchaseCompleted(Sender: TObject;
      const ProductID: string; NewTransaction: Boolean);

private 
  function Purchase(const ProductId: string): Boolean;

const
  NoAdsId = 'barcoderpro';
 var
  FProductIsValid: Boolean;
  fisPurchased :Boolean;

procedure TFormMain.FormCreate(Sender: TObject);
{$IFDEF ANDROID}

  InAppPurchase1.ApplicationLicenseKey := 'key part 1'+ 'key part 2';
   InAppPurchase1.ProductIDs.Add(NoAdsId);
   InAppPurchase1.OnSetupComplete := InAppPurchaseSetupComplete;
   InAppPurchase1.OnProductsRequestResponse := InAppPurchaseProductsRequestResponse;
   InAppPurchase1.OnPurchaseCompleted := InAppPurchasePurchaseCompleted;

 {$ENDIF}
 end;

 procedure TFormMain.InAppPurchaseSetupComplete(Sender: TObject);
begin
  FIsPurchased := False;
  try
    InAppPurchase1.QueryProducts;
  except
    on E: Exception do
      ShowMessage(e.Message);
  end;
end;

  const Products: TIAPProductList; const InvalidProductIDs: TStrings);
var
  Product: TProduct;
begin
  FIsPurchased := False;
  for Product in Products do
  begin
    if NoAdsId = Product.ProductID then
    begin
      FProductIsValid := True;
      if InAppPurchase1.IsProductPurchased(NoAdsId) then
      begin
        FIsPurchased := True;  // PURCHASED!
        ShowMessage('La version professionnelle est déjà activée');
      end;
    end;
  end;
end;


procedure TFormMain.InAppPurchasePurchaseCompleted(Sender: TObject;
  const ProductID: string; NewTransaction: Boolean);
begin
  if NewTransaction then

  else
    ShowMessage('L''achat a été annulé');
end;

function TFormMain.Purchase(const ProductId: string): Boolean;
begin
  Result := False;

  {$IFDEF ANDROID}
  if InAppPurchase1.IsSetupComplete and InAppPurchase1.CanMakeInAppPurchases then
  begin
    InAppPurchase1.PurchaseProduct(ProductId);
    Result := True;
  end
  else
    ShowMessage('L''achat n''est pas possible pour le moment. Essayez plus tard.');

  {$ENDIF}

It's supposed to be backward compatible. You should use the OnError event of InAppPurchase1 to find out what the failure is.

after i add the code below no error nothing just like the first submit any idea ?
 

 types
 procedure InAppPurchase1Error(Sender: TObject; ErrorKind: TFailureKind;
      const ErrorMessage: string);


procedure TFormMain.FormCreate(Sender: TObject);
begin
// the code before then ....this 
     InAppPurchase1.OnError := InAppPurchase1Error;
     end;
     

 procedure TFormMain.InAppPurchase1Error(Sender: TObject;
  ErrorKind: TFailureKind; const ErrorMessage: string);
begin
 ShowMessage('Une erreur est survenue pendant l''achat : ' + ErrorMessage);
end;

Just noticed your code does not call SetupInAppPurchase, so it's no wonder it does not even fire OnError.
