Android Question Converting an old app to use B4X pages

GuyBooth · Dec 30, 2022

I have a an app that has been developed in B4A over many years. It uses a starter service, and consists of:
6 Activities
6 Services
11 classes
2 code modules
I want to be able to programmatically change an icon in the main menu bar in just one of the activities, and to do this I understand I need to be using B4XPages, which I have not worked with.
Would this require a big change, lot of work? Or is there something I can do with a minimum amount of change to the existing code?

If you are using B4XPages, you "normally" use only one Activity, that is Main. Of course you can add another activity but the usual way is you use "Pages" instead. You need to add navigation bar in all pages.

It is better to move Public variables in Starter to Main.

I think that you are mistaken. This statement implies that, before B4Xpages was developed, it was impossible to change an icon in a menu bar, which is clearly not true.

B4A still supports Activity based apps. Generally speaking, if you have a reasonably large app already developed (and twelve activities/services seems reasonably large to me) then the work required to convert to B4XPages is not going to be rewarded. You should plan to change the existing code.

Perhaps I should have said "Title Bar". Posts that I have read indicate this can only be changed when using b4xPages - unless you know another way?
I have an Icon which I needs to be changed when clicked.
