The steps required are: 1. Add As ResumableSub to the resumable sub signature. 2. Call Return with the value you like to return. 3. In the calling sub, call the resumable sub with Wait For (<sub here>) Complete (Result As <matching type>) Notes & Tips - If you don't need to return a value but sti

The "index pattern" is a pattern that you can see in many examples and libraries where resumable subs are used. It is a simple solution to avoid race conditions and unexpected states. The resumable subs code like all other standard B4X code, is executed by the main thread. Still, with resumable sub

New video tutorial: 255570732 Resumable subs is a new feature added in B4J v5.50 / B4i v4.00 / B4A v7.00. It dramatically simplifies the handling of asynchronous tasks. (This feature is a variant of stackless coroutines.) The special feature of resumable subs is that they can be paused, without p

Typically you might use the value of global variables to decide what needs to be done after the next event and call an appropriate Sub when an event occurs. The Resumable Sub mechanism allows this "do, wait, then finish" to be conveniently expressed in a single Sub as sections of code separated by

Not correct. Resumable subs is a very complicated compiler feature. It is not just an event handler. It allows your sub to resume at a specific point in the exact state it was before. See the resumable subs video tutorial for more information.

The Handle sub cannot be a resumable sub itself. Why? - Wait For / Sleep must be called before the call to StartMessageLoop or they will never be executed. - Wait For / Sleep code flow is equivalent to Return so if they appear before StartMessageLoop then the message loop will never be created and

Nope. It has nothing to do with Android. The resumable subs feature is a 100% B4X compiler feature.

You cannot call Sleep or Wait For from inline code. Resumable subs is a compiler feature. The compiler converts the resumable subs code to a state machine. You can raise regular events from the inline Java code (with ba.raiseEventFromUI) and use Wait For in your B4J code.
