Android Question Does B4A have: Do Loop

RB Smissaert · Jan 1, 2019

It looks B4A doesn't have this loop construction:

Do

Loop

It is not a problem as I can do:

Do While 0 = 0

Loop

Just want to make sure I am not missing anything.

What are you trying to archieve? You cannot hold the mainthread. Android will kill your app after a short time with an ANR Error.

What are the semantics of Do...Loop ?

B4X:

Do While True
 If x = 34 Then Exit
Loop

?

This particular code can never cause an endless loop.
There is user input and there are Returns.

Thanks, Do While True is a bit neater indeed.
