Android Customizing BootAnimation

VAR-SOM-MX6 - N7.1.1 - Logo and Boot Animation customization

Changing Android Linux Penguin Logo

1. Create your logo in a .png format (logo.png), and run the following commands to convert it to a 224 colors PPM formatted image file named logo_linux_clut224.ppm:
Install the following packages on the host machine and create a ppm file from png

$ sudo apt-get install netpbm
$ pngtopnm logo.png | ppmquant 224 | pnmnoraw > logo_linux_clut224.ppm

2. Replace the default logo file in the Linux source

Note: If the Android uses GKI, the Linux kernel boot logo won't be visible.

3. Using the Linux source code directly
Follow the "Build Linux from source code" guide to get the Linux kernel source tree.
Copy your logo_linux_clut224.ppm file to drivers/video/logo/logo_linux_clut224.ppm overwriting the original logo.
Configure your kernel and enable the default logo instead of the Variscite logo: Device Drivers -> Graphics support -> Bootup logo -> Standard 224-color Linux logo (Symbol: LOGO_LINUX_CLUT224)
If you want to create a different configuration for your own logo rather than overwriting the default one, you can look at this commit which adds the Variscite Linux logo to our kernel, and make a similar patch of your own.

4. Build the android image following
Customizing the Linux kernel

Changing Android Boot Animation

1. To change boot animation you need to create a custom animation.zip file,

2. To create and obtain new bootanimation.zip follow https://android.googlesource.com/platform/frameworks/base/+/master/cmds/bootanimation/FORMAT.md and replace the newly created .zip in the build,

3. To customize your boot animation you need to create bootanimation-var1280.zip and replace it in android_build/device/variscite/common/bootanimation-var1280.zip and replace it with the existing file.

• Please note:
  

You must create the zip file in Linux as there are few dependencies and utilities, which only work correctly under Linux.
