Eclipse开发android报错The connection to adb is down

报错如下：

The connection to adb is down, and a severe error has occured.
[2010-03-11 09:36:56 - HelloOPone] You must restart adb and Eclipse.
[2010-03-11 09:36:56 - HelloOPone] Please ensure that adb is correctly located at 'E:\Android\android-sdk\platform-tools\adb.exe' and can be executed.
解决：
方法1.cmd中adb kill-server，然后adb -startserver
方法2.方法1不管用，那么在任务管理器中杀死adb.exe，然后重启Eclipse。
方法3.方法1和2都不管用，那么查看最后一句报错中：platform-tools中是否有adb.exe（我的错误就是在相关路径下面没有platform-tools文件夹，所以我选择新建一个文件夹，并且把tools中的文件全部复制到platform-tools中）

4.前面是别人总结的方法，我自己碰到的一种情况是“豌豆荚”或“手机助手”类的软件占用了adb，在任务管理器中停止“豌豆荚”及adb后重启adb或eclipse即可。

5.直接重启电脑，然后运行SDK下面的SDK Manager.exe，选择Virtual devices,启动一个模拟器即可。

6.

To restart adb by command line:

adb kill-server
adb start-server

To restart adb in Eclipse:

1. Window > Show View > Other... > Android/Devices
2. When the view is showing: View Menu of "Devices" > Reset adb
