，所以我做了一個網站，該網站可以簡單地通過使用網頁流量變成移動應用程序。當我第一次安裝apk時，它工作得很好，但問題在於，網絡只是靜態的，或者它不再被加載。我怎麼刷新一個webview？
它只是打開了像我第一次安裝它相同的內容，即使我已經改變了整個網站。我不知道問題是與webview還是與android。
我已經嘗試在php中自動刷新/自動重載功能，但它只能在移動瀏覽器中工作，並沒有在我的應用程序中工作... 任何人都知道任何解決方案？
，因爲我是在android系統的深化發展是新手我會把我的主要活動的整個代碼

確實刪除了緩存也破壞會話？因爲我的網絡具有登錄功能，並且我想要它持續很長時間，所以用戶在下次打開應用程序時不需要再次登錄 – wildape
您是否嘗試過代碼？我不確定你是否可以在這種情況下維持會議。 – fightingCoder
