我對j2me波蘭語有疑問。我使用Eclipse的IDE。以下是我的J2ME文件：幫我解決j2me波蘭語 - 藍牙問題

以上的是J2ME的我的藍牙應用程序中的兩個Java文件。當我部署在移動和執行它工作正常（顯示設備地址和名稱被發現）。
但我創建了一個新的j2me波蘭項目。將這兩個java文件複製到j2me波蘭項目的源代碼目錄中。我還通過右鍵單擊在構建路徑中添加了「\ J2ME-Polish \ import \ btapi.jar」然後選擇properties-> java build path，然後選擇選項卡庫，然後添加btapi.jar。
然後我在Eclipse中運行與Wirless的工具包J2ME應用拋光的simulaotr.then以下錯誤arised
錯誤：

爲什麼downvote？似乎他正確設置引用時遇到問題，這似乎是合法的。 –
