Create local_manifest.xml and follow the instructions under Johan's Getting the Source: Repo configuration changes for Android Dev Phone article.

That includes the kernel directory in the repo sync.

Alternatively, you can download it yourself by creating the directory and getting it via git.

I made a build with cupcake-release and kernel 2.6.27 for my ADP1(dream) yesterday, but the Camcorder App is not working, always asked me to force cloase, the error msg is "Activity Camcorder (in application Camera) is not responding.".

I also flashed the offical HTC Dream ROM in my ADP1, the Camcorder App is OK.

Can you give me any ideas?

Thanks,

Some one asked for localization. Just add to #Overrides in vendor/htc/dream-open/htc_dream.mk a PRODUCT_LOCALES

For example for us, de, zh and ru locale you have to add:

PRODUCT_LOCALES := \
en_US \
de_DE \
zh_CN \
ru_RU \

Also, it would be great to get some more info about the .config file. As I said, I get a lot of config questions and I want to get the kernel as lean and clean as possible so is there a possibility to optimize the kernel at build time? (I read something about a -O2 argument) Are there some .config settings to optimize the kernel further for the G1?
I made a post here: http://forum.xda-developers.com/showthread.php?p=4220511#post4220511 but sadly no one answered yet

Your guide is really awesome and I hope you'll adjust it to donut (especially all the Google Apps including build script) after it's release. Maybe a whole post about optimizing the android and kernel build would be something to add to these posts.

Even after following the steps as it is, the crash at boot time is happening.

I am following the 'yaffs' method to get the Proprietary binaries as mentioned on http://www.johandekoning.nl/index.php/2009/06/07/building-android-15-getting-the-source/.I could not get signed-dream_devphone_userdebug-img-148830.zip on http://www.htc.com/www/support/android/adp.html, I have used signed-dream_devphone_userdebug-img-150275.zip instead of that.

The complete build is successful, however at boot time the below message gets printed; and phone boots in a repetitive manner.

Any Guess...
