To get started with Bianca Project, you'll need to get familiar with Repo and Version Control with Git.
To initialize your local repository using the Bianca Project trees, use a command like this:
repo init -u https://github.com/BiancaProject/android.git -b 13
Then to sync up:
repo sync --force-sync --no-tags --no-clone-bundle
To build, use command:
source build/envsetup.sh
lunch $device-userdebug
m dudu
To build signed, use command:
source build/envsetup.sh
keygen
lunch $device-user
m dudu-sign
After creating the keys with keygen, you won't need to do it again. Just make sure to backup directory called certs inside the rom root directory.
