android开发入门常见错误（1）-adb报错

运行android项目时，报一下错误：

[2012-10-19 17:49:14 - AndroidTest] ------------------------------
[2012-10-19 17:49:14 - AndroidTest] Android Launch!
[2012-10-19 17:49:14 - AndroidTest] The connection to adb is down, and a severe error has occured.
[2012-10-19 17:49:14 - AndroidTest] You must restart adb and Eclipse.
[2012-10-19 17:49:14 - AndroidTest] Please ensure that adb is correctly located at 'C:\Program Files\Android\android-sdk\platform-tools\adb.exe' and can be executed.

解决办法：

Try below steps:
Close the Eclipse if running
Go to the Android SDK platform-tools directory in Command Prompt
type 

adb
kill-server

 (Eclipse should be closed before issuing these commands)
then type adb
start-server
No error message is thrown while starting ADB server, then adb is started successfully.
Now you can start Eclipse again.

it worked for me this way.

Restart your phone as well!
