Android Sync 同步 源碼問題解決方案

 一直很忙，忙的不可開交，以前我說有時間就來寫點東西，然後最近一直很忙，連論文，加新項目，事情挺多的，android源碼還是很久以前下載的，今天sync發現突然不行了，報錯：

多次嘗試無果，google之，發現google group上有這個問題，很多人問，不過都是不了了之，以前吧，百度過這個問題，在這個神奇的過度，人人都學會了CC和CV，然後就是，說是刪除.repo目錄，總之有點扯淡，刪除了repo跟重新下載有什麼區別呢？扯淡啊。可惡的bug。

 建立了目錄重新下載，最近狗日的寬頻通吃屎，速度老慢。我可不想在假期下載一天源碼。

 

 折騰了一個上午，發現瞭解決方案。其實很簡單，android源碼實際上還是用git下載的。至於repo是什麼東東，自己查唄，不浪費資源了。

其本來有圖，無奈windows發不了圖。

我就說說基本解決方案：

  除了repo .repo其餘的都刪除，cts之類的什麼刪除就行了，不需要心疼，前提是你的網路通，至於出現bad object，原因不曉得，感覺是東西太老的，無法替換掉，刪除了這些，sync會重新沖repo目錄拷貝解析出來。如果刪除了repo，後果就是你要重新下載 了。應該很長時間的。至於repo下面的東西沒什麼影響，但是不要刪除了，不然更新就蛋疼了

  最近遇到了一個大麻煩，發現以上的辦法不管用了，最近換了房子，沒網，要答辯了，把本子帶公司，打算收拾下，順便更新代碼出錯了，不記錄了，沒法重現了。

提供一個終極方案：

  比如原來捏到源碼目錄是mydroid，現在建立一個droid

$ curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo$ chmod a+x ~/bin/repo

 repo init -u https://android.googlesource.com/platform/manifest

稍等，這個目錄下面會有一個隱藏目錄 repo，把這個目錄全部複製mydroid覆蓋就行，然後droid就沒用了，然後再更新，這樣是最省事的，網速牛逼的非要把repo刪除也沒辦法，對於ip的並發google做了限制的。不能下載的

repo init -u https://android.googlesource.com/a/platform/manifest

只能這樣下載了http://source.android.com/source/downloading.html 仔細閱讀這個就好了。至於repo的各種問題可以說是bug吧。

同步出錯就是某些檔案校正失敗，最簡單的方法就是建立一個目錄初始設定檔案覆蓋舊的，語文不及格，表的的不是很明白，將就看吧
