How to build Android from the source against HTC Desire

[Guest markov00]

Hello everybody,

I'm quite new to Android, but I have some good skill in programming. I saw that Android have some limitation on bluetooth applications.

For example it have a discovery timeout of about 120 seconds(300 seconds max) and after that the application need the user help to extend the discovery time.

Another limitation is that there isn't the possibility to create bluetooth connection between two unpaired device, this limit force users to know each other and limit the possibility to build great proximity application.

So I looked into the Android source code and I found some good point to change to bypass and change these limitation.

These changes are inside some framework java classes

Now I want to know how to build a ROM from the my modified source for my Desire.

There is the need to build all the kernel and framework? or can I just to put a modified framework.jar inside the actual system?

Can I use the just released HTC Desire kernel source and put my framework inside?

I really cannot find any useful guide on how to build from the source android against Desire or modify partially the android framework.

Thanks in advance, any help are very appreciated
