[Android环境搭建错误解决二]下载Android源码时，repo出现错误解决方法

具体下载源码到方法请详见：http://source.android.com/source/downloading.html#troubleshooting-network-issues

今天用repo获取android源码：

../bin/repo init -u git://android.git.kernel.org/platform/manifest.git
出现问题：
问题一：
Traceback (most recent call last):
File "./repo", line 590, in
    main(sys.argv[1:])
File "./repo", line 557, in main
    _Init(args)
File "./repo", line 176, in _Init
    _CheckGitVersion()
File "./repo", line 205, in _CheckGitVersion
    proc = subprocess.Popen(cmd, stdout=subprocess.PIPE)
File "/usr/lib/python2.5/subprocess.py", line 594, in __init__
    errread, errwrite)
File "/usr/lib/python2.5/subprocess.py", line 1147, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory

原因：没有装git，faint
解决：
sudo apt-get install git
sudo apt-get install git-core

问题二：
装好了git，再次运行：
Traceback (most recent call last):
  File "/home/calvin/Android/Android2.0/source/.repo/repo/main.py", line 235, in
    _Main(sys.argv[1:])
  File "/home/calvin/Android/Android2.0/source/.repo/repo/main.py", line 217, in _Main
    repo._Run(argv)
  File "/home/calvin/Android/Android2.0/source/.repo/repo/main.py", line 123, in _Run
    cmd.Execute(copts, cargs)
  File "/home/calvin/Android/Android2.0/source/.repo/repo/subcmds/init.py", line 223, in Execute
    self._ConfigureUser()
  File "/home/calvin/Android/Android2.0/source/.repo/repo/subcmds/init.py", line 165, in _ConfigureUser
    name  = self._Prompt('Your Name', mp.UserName)
  File "/home/calvin/Android/Android2.0/source/.repo/repo/project.py", line 306, in UserName
    self._LoadUserIdentity()
  File "/home/calvin/Android/Android2.0/source/.repo/repo/project.py", line 319, in _LoadUserIdentity
    u = self.bare_git.var('GIT_COMMITTER_IDENT')
  File "/home/calvin/Android/Android2.0/source/.repo/repo/project.py", line 1324, in runner
    p.stderr))
error.GitError: manifests var:
*** Please tell me who you are.

Run

  git config --global user.email "[email protected]"
  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: empty ident  not allowed

解决：
看来的告知自己的身份才行。
运行：
[calvin@lihao-desktop ~/Android/Android2.0/source 18:44:28]$ git config --global user.email "[email protected]"
[calvin@lihao-desktop ~/Android/Android2.0/source 18:44:28]$ git config --global user.name "Cavin Lee"
再运行repo：
[calvin@lihao-desktop ~/Android/Android2.0/source 18:45:00]$ ../bin/repo init -u git://android.git.kernel.org/platform/manifest.git

Your Name  [Cavin Lee]:
Your Email [[email protected]]:

Your identity is: Cavin Lee
is this correct [y/n]? y

Testing colorized output (for 'repo diff', 'repo status'):
  black    red      green    yellow   blue     magenta   cyan     white
  bold     dim      ul       reverse
Enable color display in this user account (y/n)? y

repo initialized in /home/calvin/Android/Android2.0/source（出现这个提示说明成功了）

接下来同步代码：
[calvin@lihao-desktop ~/Android/Android2.0/source 18:54:50]$ ../bin/repo sync

问题三：
同步代码时不断出现诸如 “remote end hung up unexpectedly“错误：
Fetching projects:   1% (2/158)  
Initializing project platform/bootable/bootloader/legacy ...
fatal: The remote end hung up unexpectedly
error: Cannot fetch platform/bootable/bootloader/legacy
看样子是server的问题。
解决：
参考： http://android.amberfog.com/?p=230
http://code.google.com/p/android/issues/detail?id=4488

sudo gedit  .repo/repo/subcmds/sync.py
修改_Fetch函数为：

   def  _Fetch(self, projects):
    fetched  =  set()
    pm  =  Progress( ' Fetching projects ' , len(projects))
     for  project  in  projects:
      pm.update()
       while  True:
        if  project.Sync_NetworkHalf():
        fetched.add(project.gitdir)
         break
        else :
         print   >> sys.stderr,  ' error: Cannot fetch %s '   %  project.name
    pm.end()
     return  fetched

注意代码缩进问题，相应的代码段缩进要完全一样。
