本文主要解決adb connection error的問題——reset adb.

環境為真機測試，偶爾會報如下錯誤

之前都是重啟eclipse解決，但偶爾還解決不了。對於真機需要拔掉資料線，關閉eclipse重啟，重新連線手機解決。 

但由於eclipse實在過於笨重，關閉重啟時間過長。找到另外一種解決方法：

eclipse中檢視模式選擇DDMS(還有常見的java和debug檢視)， 顯示Devices視窗，若無可通過選擇window->show view->Devices顯示，再選擇下拉箭頭中的reset adb。

此時eclipse會再自動重試一次，輸入Connection attempts：1即表示成功啦
