Android Question B4xPages memory usage

I also was wondering this too because if you keep adding new panels with new views on them, then won't all these views be loaded at the same time and take up memory?

I was also wondering instead of using different panels with one activity, what about simply using different "layouts" and one activity, this way only the views in the current layout get loaded into memory, and when a new layout is loaded, all the views on the old layout are unloaded from memory - or am I misunderstanding this?

Yes. It will not save anything that any user will ever notice.

B4XPages memory usage is similar to the memory usage of activities and can be actually lower in some cases. Activities are also not destroyed when they are on the stack.

99% of memory issues are related to bitmaps and canvases. A single bitmap will take more memory than hundreds of panels.
If you encountered memory issues then you held too many images in memory. If you have many pages with many images then it makes sense to remove images as the page disappears and load them again when a page appears.
