Android：プログラムでWiFiホットスポットをオン/オフにするAndroid Marshmallow（6.0）

Question

私はこのスレッドに遭遇しました（ Android：プログラムでWifiまたはインターネット接続を有効/無効にする方法 ）。これは、私が尋ねたかったことに非常に似ています。 Ashish Sahu（ https://stackoverflow.com/users/1780737/ashish-sah ）が投稿した回答が提供する解決策を試してみましたが、他のAndroid Marshmallow（6.0）以外のバージョン。

Android MarshmallowでWiFiホットスポットを切り替えて設定する方法はありますか？私はmHotspot（ http://www.mhotspot.com/ ）を使用してみましたAndroidマシュマロの仕事ですが、それを実装する方法がわかりません。

前もって感謝します。

        }

        new wifiControllerTask(this, v2, false, context).execute(new Void[0]);
    }
}

また、メインアクティビティでは、次のように呼び出す必要があります。

    WifiAPController wifiAPController  = new WifiAPController();
    wifiAPController.wifiToggle("mHotspot", "12345678", wifiManager, context);

Marshmallow（6.0）を搭載したNexus 6でこれをテストしました

Answer 2

誰かこれを試してみませんか？

http://www.ibtimes.co.uk/how-enable-tethering-Android-6-0-Marshmallow-update-1524792

基本的にはadb Shellを実行してこれを行うと言っています：

設定はグローバルtether_dun_required 0を置きます

これは明らかにアプリで実行できることではありませんが、Androidプログラムでプログラム的にスマートフォンのテザリングをオン/オフにしたいので、それが機能する場合は、しかし、それはキャリアの制御を削除するだけのように聞こえますが、マシュマロ自体が不幸な開発者に与えた新しい制限を回避することはできません。
