How to create / change Android boot animation – This is a zip after extracting, it contains following things

  • desc.txt – The first line from desc.txt indicates as, “Width” “Height” “Framerate”
  • android – folder with 00.png to 30.png images of 681300 px which are shown once during boot
  • loading – folder which has 31.png to 79.png of 681300 px which are shown repeatedly till device is booted completely.

Note: Bootanimation png files are png with 681*300 px and black background ( not transparent png )

$ vim 
[bash] #!/bin/bash #run this script as bash filename.png rm -rf bootanimation #delete if previosuly created any BOOTANIMATION_DIR=$PWD/bootanimation mkdir $BOOTANIMATION_DIR STATIC_FILENAME=$PWD/$1 mkdir $BOOTANIMATION_DIR/android mkdir $BOOTANIMATION_DIR/loading echo "681 300 20" > $BOOTANIMATION_DIR/desc.txt echo "p 1 0 android" >> $BOOTANIMATION_DIR/desc.txt echo "p 0 10 loading" >> $BOOTANIMATION_DIR/desc.txt cd $BOOTANIMATION_DIR/android for i in {0..30} do cp $STATIC_FILENAME $i.png done cd $BOOTANIMATION_DIR/loading for i in {31..79} do cp $STATIC_FILENAME $i.png done echo "bootanimation folder created at $BOOTANIMATION_DIR" [/bash]

In above script, we are passing single image as STATIC_FILENAME which is used to create bootanimation but if you want to create real animation, you will need to generate multiple images of this animation and copy those to android and loading directory by modifying above script.

Now, copy this bootanimation folder to windows,

On Windows

select everything inside the bootanimation folder and zip them into a new compressed zip archive using 7-zip:
– Select everything inside the bootanimation folder.
– Right-click on any of the selected files/folders and from the 7-zip menu, select ‘Add to archive’.
– Use ‘zip’ as the archive format and ‘Store’ as the compression level, and click OK.

Note, here remember to select compression level to “Store” otherwise this bootanimation zip may not work. This will create a file called in the same folder.

Copy this to your android source and recompile to generate updated images which contains newly created bootanimation

OR, if you have root access, you can directly push this to android as,

$ adb push /sdcard/
$ adb shell
$ su
$ mount -o remount,rw /system
$ cd /system/media
$ mv /sdcard/ .
$ chmod 644
$ chgrp root
$ reboot

You should see a new bootanimation. 🙂
