    i creat jar lib by java,how to call a sub from java code to b4a sub?
    like this
    i creat a java file ""

    package com.example;
    import anywheresoftware.b4a.BA;
    import anywheresoftware.b4a.BA.ShortName;
    import anywheresoftware.b4a.BA.Version;
    //import anywheresoftware.b4a.BA.*;
    //@DependsOn(values={"some java library "})
    public class FirstLib {
    public int add(int x, int y) {
    return x + y;
    public int add2(int x, int y) {
    return x + y;

    if i change this
    public int add2(int x, int y) {
    int c=0;
    return c;

    in b4a ,have a sub
    sub sub1(x as int ,y as int)
    return x+y
    end sub

    c=b4a.main.sub1(x,y);i think it's wrong,how can i write the code?
