Android Question B4A application integration with 3rd party apps

[Pantelis Loizou]

hi to everyone

i am trying to integrate my b4a app with a 3rd party POS Payment application. unfortunately the provider didn't provides me any .jar or .aar files and i am wondering if is possible to achieve this goal with a pure b4a coding or i am wasting my time. This is the link: https://github.com/wallee-payment/android-till-sdk

You can use JavaObject to call inline Java code.

Anything is possible, it is too diffcult to achieve this goal with a pure b4a coding. but it is easy to compile the sdk to aar using AS.
The aar is attached.
It should work, this is the screenshot of the sample app

The sample is from https://github.com/wallee-payment/android-till-sample-app, it was built with the aar on the AS.
How to use aar? as aeric said at post#2, you can refer to the https://www.b4x.com/android/forum/t...onaljar-and-javaobject-picasso.40904/#content.

Spoiler: AuthorizeTransactionActivity

   protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.authorize_transaction_activity);

        final EditText amountField = findViewById(R.id.editTextAmount);
        final EditText currencyField = findViewById(R.id.editTextCurrency);
        final CheckBox shouldReserve = findViewById(R.id.shouldReserve);

        findViewById(R.id.authorizeButton).setOnClickListener(view -> {
            String amountString = amountField.getText().toString();
            String currencyString = currencyField.getText().toString();

            List<LineItem> lineItems = new LineItem.ListBuilder("foo", new BigDecimal(amountString))
                    .getCurrent()
                    .setName("bar")
                    .getListBuilder()
                    .build();

            Transaction transaction = new Transaction.Builder(lineItems)
                    .setCurrency(Currency.getInstance(currencyString))
                    .setInvoiceReference("1")
                    .setMerchantReference("MREF-123")
                    .setTransactionProcessingBehavior(
                            shouldReserve.isChecked() ? TransactionProcessingBehavior.RESERVE : TransactionProcessingBehavior.COMPLETE_IMMEDIATELY
                    )
                    .build();

            try {
                client.authorizeTransaction(transaction);
            } catch (Exception e) {
                e.printStackTrace();
            }
        });

        findViewById(R.id.returnButton).setOnClickListener(view -> finish());

        client = new ApiClient(new MockResponseHandler(this));
        client.bind(this);
    }

The code is simple, you just need to translate it into javaobject of the b4a.
The key job is you need to understand how wallee payment works

Ask ChatGPT to translate the code.
