This article describe what a bootanimation is and where it is used.

A bootanimation is the animation that plays when a device powers on—usually right after the logo screen and before the home screen or login.

In Detail:

• Where it's used: Android devices, embedded Linux systems, custom ROMs, kiosks, and some specialized hardware like AIOs (All-In-One systems).

• What it is: A zip file (bootanimation.zip) that contains:

  • A series of PNG images

  • A desc.txt file that defines resolution, frame rate, and sequence

Purpose:

• Visual feedback that the device is starting

• Branding (e.g., Elo, Samsung, Pixel use custom bootanimations)

• Can be customized to reflect a theme or organization

Example Contents of bootanimation.zip:

Typical Location:

• /system/media/bootanimation.zip (default)

• /data/local/bootanimation.zip (custom override)

Bottom Line:

A bootanimation is a simple image-based splash sequence shown during device startup. It's optional but often used for a polished or branded startup experience.
