Android Question Activity parameter to Java method from B4A

    Hi Erel,

    I'm trying to interface with a 3rd party Android credit card app from B4A. It will start the app, but locks up. I suspect the 1st parameter to initiatePayment is wrong. It locks up when I call it with the B4A Activity.

    Note that TransactionRequest is a structure which is created by another method in the same jar. It seems to work OK, so I'm assuming the problem is the 1st parameter.

    public void Stage3(Activity BA) {

    // create a currency object with specified locale

    try {

    String orderId = "456789";

    PaylevenApi.initiatePayment(BA, orderId, request);

    }
    catch (NumberFormatException e) {
    Toast.makeText(getApplicationContext(), "invalid_amount", Toast.LENGTH_LONG).show();
    }
    }


    Supplied documentation is as follows:

    "Issues a TransactionRequest to the app. You need to override onActivityResult of your Activity to receive the response"
    Parameters:
    activity - the activity that will receive the result
    orderId - a unique id that identifies the payment.

    I think it should be something like this;
    Code:
    public void Stage3(BA ba) {

    // create a currency object with specified locale

    try {

    String orderId = "456789";

    PaylevenApi.initiatePayment(ba.Activity, orderId, request);

    }
    catch (NumberFormatException e) {
    Toast.makeText(ba.context, "invalid_amount", Toast.LENGTH_LONG).show();
    }
    }
    i'm not familiar with your library, but this should work.

    Good luck!

    ba.Activity will be null unless:

    The java class is marked with the @BA.ActivtyObject annotation.

    And

    The Stage3 method is callled from an Activty (not a Service or Code module).
