Android Question Reload a MsgBox after an Activity Pause

[rbirago]

If I want to warn the user that I'll do an action simply I can use a MsgboxAsync with a Wait For MsgboxResult and after all the operations I want to add.
In this way the user is warned, he clicks on ok and the operations are performed....
But if the user waits so long and the activity goes in Pause when the user refreshes the device to continue the msgbox doesn't appear (the form appears)! How to manage this?
Thanks

I don't know if this will work depending on your program flow, but...

Before you display the MsgBox, set a Boolean flag in a variable, and then clear the flag if the user clicks OK.

Then in the Activity_Resume check to see if this flag is still set, and if so redisplay the MsgBox.

It should be a good solution if in the activity there is only one situation of this kind...but if I have more than one similar case this way is very tricky. Is it possible that there is not a straight way to manage a msgbox answer after a Pause/Resume? It is not a so strange situation...

So then set a numerical value to the flag so it will remember which "state" it was last in:

So when Flag=1 then display Msgbox("Do backup?")
or if Flag = 2 then MsgBox("Restore Data?"), etc.

The variable then acts like a "state machine".

Yes, shurely it works. Don't you think that is really strange that there is not a straight way to manage it? If you think about this case could occur in all circumstances. So every time you want to have an acknowledge of a user you have to build this mechanism.
Anyway: thank you for the suggestion. If none has a simpler way I'll follow this way.

Yeah, I would think that the msgbox should stay visible on the activity even if the activity was hidden and then made visible.

 

[rbirago]

Exatly, I want to believe that there is a way to achieve this.
Also because in the previous example I cannot resolve the trick by a pointer: if I have different subs that have to wait for an acknowledge of the user the problem is not to show different messages, but to continue the different operations of each specific sub!

Use B4XDialog instead of Msgbox. It will not be discarded when the activity is paused.

 

[rbirago]

That's the solution, thanks!
but...at this point...it is a fact that Msgbox and MsgboxAsync have this important limit: don't you think that should both be considered deprecated? B4xDialog is the only all-purposes answer!

Msgbox is deprecated. MsgboxAsync is not deprecated. This is how Msgbox(Async) always behaved. It was removed when the activity is paused.

ok, thanks
