$ repo init -u https://android.googlesource.com/platform/manifest -b android-4.4.2_r1
$ repo sync
使用repo sync同步下载代码时因为网络原因可能会经常断线，可以使用下面的脚本来做个脚本文件，让它中断后，又自动下载
创建脚本download.sh
#!/bin/bash
echo "=========start repo sync=============="
./repo sync
while [ $? == 1 ]; do
echo "======sync failed, re-sync again======"
sleep 3
./repo sync
done
错误笔记：
git config --global user.email "you@example.com"
git config --global user.name "Your Name"
to set your account's default identity.
Omit --global to set the identity only in this repository.
fatal: unable to auto-detect email address (got 'lhy@Ubuntu.(none)')
