Android Question How to receive events from the INLINE Java code

[EduardoElias]

Hi there!

I have a class in Java written to wrap a complex payment java library

I have instantiated the class and now everything fine, however I have some events happening and I need to comunicate with the B4A code to take action:

    @Override
    public void onPrinterError(String s) {
    }
   
    @Override
    public void onConfig() {
        BA.Log("Transaction.onConfig");
    }

    @Override
    public void onBegin() {
        BA.Log("Transaction.onBegin");
    }

    @Override
    public void onProgress(String progressMessage) {
        BA.Log("Transaction.onProgress "+progressMessage);
    }

where is this BA.Log I need to call the B4A code eventually passing some param and receiving some information back.

How It can be done?


my full code above:

#Region  Project Attributes
    #ApplicationLabel: yNexu
    #VersionCode: 1
    #VersionName: 1.1
    'SupportedOrientations possible values: unspecified, landscape or portrait.
    #SupportedOrientations: unspecified
    #CanInstallToExternalStorage: False
    #AdditionalJar: NexuPayment-release-114.aar
#End Region

#Region  Activity Attributes
    #FullScreen: False
    #IncludeTitle: True
#End Region

Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'These variables can be accessed from all modules.
    Dim nexu, nexupayment As JavaObject
End Sub

Sub Globals
    'These global variables will be redeclared each time the activity is created.
End Sub

Sub GetContext As JavaObject
    Return GetBA.GetField("context")
End Sub

Sub GetBA As JavaObject
    Dim jo As JavaObject
    Dim cls As String = Me
    cls = cls.SubString("class ".Length)
    jo.InitializeStatic(cls)
    Return jo.GetFieldJO("processBA")
End Sub

Sub Activity_Create(FirstTime As Boolean)
    
    If FirstTime Then
        nexu.InitializeContext
    End If
    
    Activity.LoadLayout("layout")
