好吧，現在我真的陷入了這裏。我不知道該做什麼，去哪裏或任何事情！Dex Loader無法執行多個dex文件定義
我一直在試圖卸載，重新安裝SDK和Eclipse版本，試圖谷歌這一點，但Nu-呃...沒有！
我可以運行我的模擬器的應用程序，但我不能將其導出...

您是否嘗試過使用ant直接構建它，而不是通過eclipse來構建它？ ？如果是這樣，你可以發佈完整的構建日誌嗎？另外，你是否在項目中包含任何庫項目或jar文件？ – JesusFreke
不，我沒有。不，我沒有其他的圖書館項目或.jars，我只使用Android 2.3.3，我有一個存儲在資產文件夾中的數據庫。這一直在工作之前，但自更新ADT和Eclipse以來，這已失敗。我還沒有試過螞蟻，現在我沒有時間去做：/ – DreamHawk
@ user889771相同，我更新了adt，問題開始發生 – Rob
