第一個：[2012-11-09 13:15:14 - Tesa] Android Launch![2012-11-09 13:15:14 - Tesa] The connection to adb is down, and a severe error has occured.[2012-11-09 13:15:14 - Tesa] You must restart adb and Eclipse.[2012-11-09 13:15:14 - Tesa] Please ensure that adb is correctly located at 'D:\學習\android-sdk-windows\platform-tools\adb.exe' and can be executed.這個解決方案有多種：1.進程中強制結束adb.exe，再重啟Eclipse。2.如果上面方法不行，看一下有沒有類似91手機小幫手等工具正在開啟，佔用了該進程，有的話就關掉。3.我遇到的問題的解決方案：把tools檔案夾中的adb.exe複製到platform-tools檔案夾中，是從網上看到的方法，我用的2.3AVD。
