Android Question B4XPages.GlobalContext

[PhilipBrown]

Does this have any practical use? Should it be documented?

It is shortly explained here: https://www.b4x.com/android/forum/t...framework-for-managing-multiple-pages.118901/
It is a simple placeholder. You can store whatever you like there.

The use case is with cross platform apps that can start in the background. For example after they receive a push notification. In that case B4XPages will not be initialized but B4XPages.GlobalContext will still be available (if assigned properly when the app starts, in the starter service in B4A).

Sub Message_Received
 Starter.SQL.DoSomething 'not cross platform
 Dim sql As SQL = B4XPages.GlobalContext 'cross platform
 sql.DoSomething

Many thanks.
The page https://www.b4x.com/android/forum/t...framework-for-managing-multiple-pages.118901/ does not actually mention GlobalContext so is not found in a search of the Forum.

does not actually mention GlobalContext

The last paragraph of post#1 of that link makes mention of it.

In fact that page talks about B4XPages.B4XGlobalContext not B4XPages.GlobalContext.
I note also it talks about initializing it in Service_Create of the starter service, but in fact B4XPages.GlobalContext can hold standard variables with being initialized.

Fixed.

That's true. It can hold whatever you like. It does make sense to initialize that object in Service_Create of the starter service. This way it will be available in all cases.
