所以我問了另一個問題，我的電子郵件每次嘗試發送時都會導致錯誤。原來，簡單的解決方案是沒有聲明特定導入的類定義。所以，我確定我在我的類路徑中有jar，並將其添加爲庫文件並導入代碼。但是，只要我停止輸入進口聲明，它刪除了自己。從技術上講，它很快變成灰色，然後被刪除。我試圖通過使用不同的API來輸入導入，然後在java studio中打開它，但它會使它變灰，並在compliling時刪除。我現在不在使用android studio的電腦上，但我不知道爲什麼它不工作。其他人能夠告訴我我需要導入該類，但他們不知道爲什麼它會自動刪除。我感謝任何幫助。導入鍵入後刪除（Android studio，Java）
