The connection to adb is down, and a severe error has occured. 解决方法

1.报错：

BUILD FAILED

D:\workspace\ganji\build.xml:144: The following error occurred while executing this line:

D:\workspace\ganji\build.xml:271: Unable to delete file D:\workspace\ganji\tmp\proguard\tmp.jar

解决：

已经开了一个模拟器了，无法重新编译，必须关闭一个。

 

 

2.报错：

The connection to adb is down, and a severe error has occured.

解决：

cmd跳到sdk tools文件路径下

adb kill-server

然后再adb start-server

或者：右键项目——>Android Tools ——>Fix Project Properties，再run。

 

3.报错：

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 'D:\OPhoneSDK_1.5

\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（或者在相关路径下面有没有platform-tools文件夹

，如果没有，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）
