===========solution:==========================
[plain] 
（http://source.android.com/source/downloading.html）有段說明，如果認真執行就可解決。 
1. 瀏覽器登入https://android.googlesource.com/new-password，並用gmail帳號登入； 
2. 點擊網頁上的“允許訪問”，得到類似： 
[plain] 
1. machine android.googlesource.com login git-<userName>.gmail.com password <password>  
2. machine android-review.googlesource.com login git-<userName>.gmail.com password <password>  
  
的資訊。 
3. 把上面那段資訊（<userName>和<password>用自己得到的真實資訊）追加到~/.netrc檔案結尾； 
4. 的URI更改為https://android.googlesource.com/a/platform/manifest（中間加上了“/a”）。 
然後按照官網描述的正常步驟操作，即可拉下Android源碼。 
官方的說法是：因為訪問基本是匿名的，為了防止串連過多，對同一IP地址的串連數做了一定的限制。看來是用gmail帳號進行認證。 www.2cto.com
這樣的話，在公司網路內或者用虛擬機器下載的話，會經常遇到這問題。
