Android 开机动画

1.原始的android的开机动画，貌似是android的字体然后晃动晃动。

其实这不是动画，只是两张图片。一张mask在上面，下面一张图片在不停的动。

他们在如下目录下 

./frameworks/base/core/res/assets/images/android-logo-mask.png

./frameworks/base/core/res/assets/images/android-logo-shine.png。

2.

I suggest that we should use bootanimation.zip instead of default image android-logo-mask.png
in the subsequent product.

I will introduce the bootanimation.zip below, and you can find the two examples in the attachment.
All of you need to do is just to execute a command:
  adb push ./bootanimation.zip /data/local/bootanimation.zip

2.1. location of bootanimation.zip

   1) /data/local/bootanimation.zip, or
   2) /system/media/bootanimation.zip

 While power on, handset will retrieve the bootanimation.zip from the location one by one;
 If it can not get any of the bootanimation.zip,  it will read
   android-logo-mask.png,
   android-logo-shine.png

2.2. content of bootanimation.zip
   It includes two directory and a file.
    -rw-r--r-- 1 fengwang act     38 2010-08-10 16:55 desc.txt
  drwxr-xr-x 2 fengwang act   2048 2010-08-10 16:57 part0
  drwxr-xr-x 2 fengwang act   2048 2010-08-10 16:57 part1

  The png images is placed in the directory "part0", "part1".
 
  format of desc.txt, for example
   480 800 15
    p 1 0 part0
    p 0 0 part1

  480--width of the image, 800--height of the image, 15--frames of second
  p 1, display one time
  p 0, display recycling till handset power on finished

  The images can be larger than the screen, and the handset will scale them automatically

2.3. how to create the bootanimation.zip
   cd ./bootanimation
   zip -r -0 bootanimation.zip part0 part1 desc.txt
   adb push ./bootanimation.zip /data/local/bootanimation.zip

   The -0 parameter is mandotary. It means zip with "store only" mode.

2.4. reboot the handset, you will see the new animation images .
