How I can close an activity from another activity?

If activity B is runing then the only one you can finish is activity B. That´s how android works.

What you can do is:

Asuming you have activity MAIN and B AND C.
in main when starting B

StartActivity(B)

in B then when starting C

Activity.finish
StartActivity(C)

When you then finish C youll get back to MAIN; not to B cause you finished it

in B then when starting C

Hello,
I am used to order it differently. Is it a problem ? Thanks

StartActivity(C)
Activity.Finish

But if I do not finish the activity B and from C back to main, how can I close it?

Is it a problem ?

Probably no cause BOTH commands are executed after the sub finishes.

But if I do not finish the activity B and from C back to main, how can I close it?

You can NOT close activity B from C! ONLY B can. Or the system when it kills your process.
You can do in C

activity.finish
startactivity(main)

But B stays till the task is killed or reopened again.

If I finish an activity, global variables can then use them in another activity?

Activity A
Sub Process_Globals

Dim Client As String

End Sub

Activity B

a.client

 

[DonManfred]

honestly i dont know. Try it!

But i i should guess or give an answer i would say:

Yes, as long as the process is running.

Yes, as long as the process is running.

And if some data have to be preserved, you can use a code module and refer to it (perhaps simpler to manage in my opinion)
