java.lang.IllegalAccessError class ref在預先驗證的類中已解析爲意外的實現

Question

當我按下一個啓動MainActivity中的方法的按鈕時，出現「java.lang.IllegalAccessError class ref in preverified class resolved to unexpected implementation」錯誤應該開始一個新的活動。我能做些什麼來解決這個問題？這是我第一次嘗試做一個Android應用程序，所以生病需要一步一步的指示:)

此外，我還沒有能夠測試它是否工作，但如果您發現我的AugiActivity服務實施或本地任何錯誤廣播實施隨時讓我知道。

謝謝！

FYI：MainActivity開始導航活動，啓動服務AugiActivity

AUGI活動發送本地廣播消息導航

Answer 1

我解決它。似乎在libs文件夾中包含maps.jar文件是個不錯的主意。刪除它糾正了這個問題。謝謝大家。

Answer 2

在我的情況下，我改變了Intelij Idea的項目設置。轉到模塊 - >依賴項，然後將lib的範圍設置爲'已提供'。

在打開模塊設置 -

Answer 3

>依賴性

設定範圍爲線

{包括= [*。罐子]，DIR =庫}

到提供
