Okay so some of you have probably figured this out but since it took me so long and I finally ended up pulling apart the Jager .zip install file to figure it out, here's now you do it. Go look at any tutorial you want for making a boot animation, I'm not going into those speciffics here. Instead of putting your first animation pictures in the folder part0, put it in the folder 'android' In desc.txt you need to change the second line from 'p 1 0 part0' to 'p 1 0 android' substituting your loop number and frame delay appropriately of course. Now just make sure you push bootanimation.zip and android_audio.mp3 to /data/local (this is NOT on the SD card but you can push to it without superuser) To check to make sure it's working, do adb shell and use the bootanimation command. You can get out of it with a control-c (the audio will play but the screen will probbaly still timeout so if it goes blank just hit the power button).
