Welcome to the Fitbit Community, @sarika30.
I appreciate your participation in the Forums and sharing your concern on how you can use animation as your clock face background. I am glad to hear a basic clock face you've created is working fine. I recommend checking this help article with useful information: How do I develop new apps for the Fitbit App Gallery?
If this doesn't respond your question, please let me know and I will be glad to investigate further.
I'll be around.
