Android Tips #2

1. How to change file ownership

ex) adb  shell chown 0.2000 /system/bin/bluetoothd

2. android_filesystem_config.h contains predefined User and Group IDs

3. What you must check when kernel panic happens:

And read all the other "Kernel panic" threads for all the other 
suggestions. 

Again (as a summary): 

1. You need a double buffering frame-buffer driver. 
2. You need MMAP() support on the /data file system. 
3. You need all the Android specific kernel code enabled in your 
kernel. 
4. You need enough RAM to run all the Android code (start with 
192meg). 
5. You need various other features of the Linux kernel enabled and 
running (see a config file from a running Android build). 
6. You may need specific support for your board (drivers and/or 
binding subsystems to drivers). 
7. You may need specific support for your processor architecture (and 
don't assume all architectures are equal). 
8. You need a working fake (if not real) power management driver. 

You also need to be able to use logcat to see the userland log 
messages to see where the system is really dieing.
