Activity2 does not load any layout ... yet you declare the B4XGifView1 here , and in Activity_Create is this...

B4XGifView1.SetGif(File.DirAssets, "candldeon.gif")

B4XMainPage loads "MainPage" layout which contains the B4XGifView ...

Declare the View and call the the above in B4XMainPage Class and the problem is solved.
Or load a layout in Activity2 than contains a B4XGifView.

You need to add it with the designer.

If you need many: [B4X] I need 100 <custom view here>s. How to add programmatically?
