Change the default animation for a tablet with a different animation

Question

My question is, what animation format does the Pepper tablet support by default (I want to change it using bubbles with some other animation). What should I put in value MainActivityas the ( image, opengl, videoor something else).

Also what is the default animation format - one that has bubbles?

Reading this Change the default pepper screen I was able to change the default animation to some image. But when I try to use animation .gif, one of the following problems occurs:

• If MainActivitythere is image: it .gifis static - it acts like an image - I did not expect anything.

• If MainActivity- opengl: it plays the default animation, not a new one .gif.

• If MainActivity- video: A warning appears on your tablet saying that "this video cannot be played."

Here is the link from .gifI experimented: link .
