Ubuntu 16.04 编译Android 8

安装依赖：

copy
sudo apt-get install openjdk-8-jdk git ccache automake lzop bison gperf build-essential zip curl zlib1g-dev zlib1g-dev:i386 g++-multilib python-networkx libxml2-utils bzip2 libbz2-dev libbz2-1.0 libghc-bzlib-dev squashfs-tools pngcrush schedtool dpkg-dev liblz4-tool make optipng maven

1.将repo中goole的连接
REPO_URL = 'https://gerrit.googlesource.com/git-repo'
修改为清华的连接
REPO_URL = 'https://aosp.tuna.tsinghua.edu.cn/android/git-repo'
2.初始化

copy
repo init -u https://aosp.tuna.tsinghua.edu.cn/platform/manifest -b android-7.1.1_r22

manifest见 https://android.googlesource.com/platform/manifest

可加上--depth参数：（--depth=DEPTH       create a shallow clone with given depth; see git clone）

copy
repo init --depth=1 -u https://aosp.tuna.tsinghua.edu.cn/platform/manifest -b android-9.0.0_r48

3.下载

copy
repo sync

或者

copy
repo sync -c --no-clone-bundle --no-tags -j$(nproc)

• -c, --current-branch  fetch only current branch from server
• --no-clone-bundle   disable use of /clone.bundle on HTTP/HTTPS
• --no-tags           don't fetch tags in the manifest

通过在init及sync时添加额外参数可明显减小代码量，以android-9.0.0_r48为例，不添加额外参数，.repo目录大小为31G，而使用额外参数后大小仅为14G。
