Android Sync 同步 源码问题解决方案

 一直很忙，忙的不可开交，以前我说有时间就来写点东西，然后最近一直很忙，连论文，加新项目，事情挺多的，android源码还是很久以前下载的，今天sync发现突然不行了，报错：

多次尝试无果，google之，发现google group上有这个问题，很多人问，不过都是不了了之，以前吧，百度过这个问题，在这个神奇的过度，人人都学会了CC和CV，然后就是，说是删除.repo目录，总之有点扯淡，删除了repo跟重新下载有什么区别呢？扯淡啊。可恶的bug。

 新建了目录重新下载，最近狗日的宽带通吃屎，速度老慢。我可不想在假期下载一天源码。

 

 折腾了一个上午，发现了解决方案。其实很简单，android源码实际上还是用git下载的。至于repo是什么东东，自己查呗，不浪费资源了。

其本来有图，无奈windows发不了图。

我就说说基本解决方法：

  除了repo .repo其余的都删除，cts之类的什么删除就行了，不需要心疼，前提是你的网络通，至于出现bad object，原因不晓得，感觉是东西太老的，无法替换掉，删除了这些，sync会重新冲repo目录拷贝解析出来。如果删除了repo，后果就是你要重新下载 了。应该很长时间的。至于repo下面的东西没什么影响，但是不要删除了，不然更新就蛋疼了

  最近遇到了一个大麻烦，发现以上的办法不管用了，最近换了房子，没网，要答辩了，把本子带公司，打算收拾下，顺便更新代码出错了，不记录了，没法重现了。

提供一个终极方案：

  比如原来捏到源码目录是mydroid，现在新建一个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，这个目录下面会有一个隐藏目录 repo，把这个目录全部复制mydroid覆盖就行，然后droid就没用了，然后再更新，这样是最省事的，网速牛逼的非要把repo删除也没办法，对于ip的并发google做了限制的。不能下载的

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

只能这样下载了http://source.android.com/source/downloading.html 仔细阅读这个就好了。至于repo的各种问题可以说是bug吧。

同步出错就是某些文件校验失败，最简单的方法就是新建一个目录初始化文件覆盖旧的，语文不及格，表的的不是很明白，将就看吧
