我已經創建了登錄應用程序，這是我原生應用程序構建過程的一部分。有幾個端點使用登錄會話。我獲得登錄終結點的成功結果，但它不會將其會話轉發到下一個活動。例如：如果用戶登錄成功，他可以在其他活動中訪問其他功能。但是，當我試圖切換活動時，我得到「用戶需要登錄」。如何在客戶端更改活動時創建自動處理的http連接

所以根據你我必須解析成功登錄感興趣的課程權利。但是端點的其餘部分不會將這些憑據作爲參數。我怎麼能夠把這個成功的消息發送給感興趣的班級呢？請你用一些示例代碼來解釋。 @Gabe Sechan – Arun
調查BroadcastReceivers。或者一個活動巴士。或者RxJava可觀察的。或者只是一個帶有自己的回調系統的綁定服務。有幾十種方式來提醒服務的活動，做一些研究。 –
Ohh好的..謝謝@Gabe Sechan – Arun
