Android Question How to get the return value of getBA().raiseEventFromUI

[BOHANG]

I want to know how to get the return value from a function called B4X from inline JAVA.

Private Sub Button1_Click
Me.As(JavaObject).RunMethod("sum", Array(1,2))
End Sub

Sub getsum(a As Int,b As Int) As String
Return a+b
End Sub

#if java
public void sum(Int a,Int b){
    getBA().raiseEventFromUI(this, "getsum",a,b);
    BA.Log(???); //How to get the return value=3
}
#End If

The first question has not been answered yet, and now there is also a new question. How to call Resumable subs that return values from inline JAVA

Sub a()As ResumableSub
dim i as int
for i = 1 to 10
    log(i)
    sleep(10)
next
return true
End Sub

#if java
public void test(){
   // How to use functions like Wait for to call a here
    BA.Log("finish");
}
#End If

raiseEventFromUI cannot return a value as the event isn't raised immediately. You need to use raiseEvent instead. This adds some other complexities.

Impossible.

Tip: don't waste your time with Java. Write B4X code.
