打開eclipse提示：「Failed to initialize Monitor Threa...

今天突然遇到這個問題，很奇怪，上週五還好好的，週末沒有打開過eclipse。

百度了一下，答案都千篇一概，提示關掉防火牆，重啓adb，可是我試了，對我都沒有效果。
後來在http://stackoverflow.com上面找到了這個問題，按照建議作，果真好了。

疑問：
雖然暫時沒有問題了，可是我仍是不明白爲何會這樣，期待有經驗的的高手們路過的時候給點參考。

下面是http://stackoverflow.com上的問題和解決方法，可能不必定能解決全部的該類問題，可是貼出來，但願有點幫助。

問題：

I have a problem, when I want to start developing applications for android, I did everything like in manualhere but after installing ADT Plugin in Eclipse I am still getting this error :

[2011-12-29 14:34:56 - ddms] Failed to initialize Monitor Thread: Unable to establish loopback connection

then, if I try to run an application this appear :

[2011-12-29 14:41:42 - TestApp] ------------------------------ [2011-12-29 14:41:42 - TestApp] Android Launch! [2011-12-29 14:41:42 - TestApp] Connection with adb was interrupted. [2011-12-29 14:41:42 - TestApp] 0 attempts have been made to reconnect. [2011-12-29 14:41:42 - TestApp] You may want to manually restart adb from the Devices view.

解決方法：

No need to turn off tredo interface: simply add -Djava.net.preferIPv4Stack=true ineclipse.ini:

 openFile -vmargs -Djava.net.preferIPv4Stack=true
