Android Question Fireworks Animation

[Pete_S]

Has anyone developed any visual effects similar to the attached gifs? The attached gifs have solid backgrounds, I would be interested in having transparent backgrounds instead.

So far I see this only:

I think this kind of animation would be useful for highlighting certain parts of the screen in a fun way. Maybe to notify the user of an interface change for example.

If this hasn't already been created, what method could I use to create it myself? Would I use an ImageView with an animated gif with transparent background for example? Or would I use an animation library?

Or would I use an animation library?

No.

Would I use an ImageView with an animated gif with transparent background for example?

Probably no.

If this hasn't already been created, what method could I use to create it myself?

B4XCanvas with a loop and a call to Sleep inside the loop.
