關於android：The connection to adb is down, and a severe error

點擊項目run，報了這樣的錯，前幾天都好好的： [2013-09-14 15:27:13 - QualityPicture_Client1.3.1.9.7.1] ------------------------------ [2013-09-14 15:27:13 - QualityPicture_Client1.3.1.9.7.1] Android Launch![2013-09-14 15:27:13 - QualityPicture_Client1.3.1.9.7.1] The connection to adb is down, and a severe error has occured.[2013-09-14 15:27:13 - QualityPicture_Client1.3.1.9.7.1] You must restart adb and Eclipse.[2013-09-14 15:27:13 - QualityPicture_Client1.3.1.9.7.1] Please ensure that adb is correctly located at 'D:\adt-bundle-windows-x86\sdk\platform-tools\adb.exe' and can be executed.   其實很簡單，你要改一下系統的環境變數path，由'D:\adt-bundle-windows-x86\sdk\tools改成了'D:\adt-bundle-windows-x86\sdk\platform-tools 你查看\tools目錄發現多了一個adb_has_moved.txt檔案，裡面明確告訴了原因：The adb tool has moved to platform-tools。原來從SDK R8以後，SDK需要有一個新的組件支援，這個組件叫做Platform-tools，adb已經遷移到這個目錄下去了。並且 adb_has_moved.txt檔案也說明需要在PATH環境變數中增加\platform-tools路徑，以便能夠從任何地方啟動adb.exe。  然後重啟電腦，啟動eclipse，點擊run，又報如下錯誤：[2013-09-14 15:27:13 - QualityPicture_Client1.3.1.9.7.1]  ADB server didn't ACK [2013-09-14 15:27:13 - QualityPicture_Client1.3.1.9.7.1] * failed to start daemon *   於是我就百度，參考了該篇文章(http://www.cnblogs.com/longqi293/archive/2012/06/19/2554801.html點擊開啟連結)。可是我沒有出現那樣的情況。但我還是照著上面的操作，殺死服務，然後啟動服務。然後我就重啟一下，就可以了。   還有人說按如片的方法：
