權限訪問WIFI在Android 6

我是新來的android工作室，我以前在Android版本5.1爲我的應用程序工作，它工作正常，但現在在6我不能獲得許可或我不知道如果我的方法是錯誤的。我正在製作一個應用程序，該應用程序使用可用於我的手機的接入點列表。但即使我被授予許可，我的應用程序不會顯示我的wifi列表，但相同的代碼適用於早期版本。權限訪問WIFI在Android 6

你嘗試加入 <使用許可權的android：name = 「android.permission.INTERNET對」/>和<使用許可權的android：NAME = 「android.permission.ACCESS_NETWORK_STATE」/> 您清單除了指定的權限？ – vidulaJ

它也不工作，我的編譯器甚至沒有輸入我的獲取權限方法 –
