這裏的場景是我連接到一個wifi和我的應用程序正在計算路線。它應該仍然有效，因爲它支持離線導航。應該有一種方法來強制SDK脫機工作，即使它在線。謝謝！這裏的SDK離線導航不起作用
這是我得到的日誌。

似乎您的設備無法連接到路由服務器？仔細檢查您的設備是否具有連接性？你在防火牆後面嗎？也許也是一個暫時的問題？一般來說，如果所有必要數據都可以脫機使用，那麼Mobile SDK Premium會離線執行路由計算。所以，當你在開始路由計算之前下載地圖數據（例如通過MapLoader）時，這應該起作用。如果您請求交通感知路由，當然也需要連接到交通服務器。 – Marco
感謝@Marco的迴應。我已經下載了我正在工作的地區的地圖。我測試過瀏覽該地區，我可以看到地圖區域。該設備已連接到代理服務器，並且之前正在運行。如果代理不允許繼續進行請求。應該有一種方法，SDK將離線重新計算路由。 – neilQ5
