title: How to create a custom boot screen in android before building the source?
body: <p>How can i change the default boot image in android in OS level. I am making a customized android build(I use source of froyo) . I want to replace the existing image with my custom image. I have read somewhere that we have to make some changes to frameworks/base/libs/surfaceflinger/BootAnimation.cpp. But that file seems missing. </p>
  
  <p>Can someone give some links to tutorials on how to do this.</p>
