5.13.2. How to custom an Android boot
animation?
1. Overview
The Android boot animation is used script to
load PNG files when the device boots. It is
contained within an uncompressed zip file called
bootanimation.zip.
2. Inside the bootanimation.zip file
The bootanimation.zip as follow:
• The image folder (Contains PNG images named
in incremental numbers)
• The desc.txt file
(1) The image folder
These contain PNG images named in numbers,
starting from something like 0000.png or 0001.
png and proceeding with increments of 1. There
has to be at least one folder and there is no
known upper limit to the number of folders.
(2) The desc.txt file
This file defines how the images in the folder(s)
are displayed during the boot animation, in the
following format:
- Width Height Frame-rate
-
mode Loop delay-time Folder1
-
mode Loop delay-time Folder2
An example of a desc.txt file is:
-
1920 1080 30
-
p 1 0 part0
- p 0 0 part1
a. The first line
1920 and 1080 define the width and height of
the screen resolution.
30 is the frame rate in fps (frames per
second) i.e. number of images to display per
second.
b. The second and third lines have a same
format.
The first ‘p’ defines play mode is immediately
stop playing when boot complete.
The number after ‘p’ defines repeat mode
- specifying 0 would make the part loop
indefinitely till the device has boot
complete.
- specifying 1 would make the part
playback once.
The next number defines the delay time(ms).
For example, if set 10, when all image files has
been playback, system will delay 10ms.
The part0 and part1 are image folder name.
The above example, the boot animation will play at
a resolution of 1920 by 1080 pixels, at a frame rate
