イーサネット (WiFi) 経由で KNX バスに接続するために、Android 用の Java でこの単純なコードを作成しました。残念ながら機能していません

このコードは私の Android 携帯電話では実行できません。私がそれを実行すると、Android携帯電話で「アプリケーションが機能しなくなりました....」というメッセージが表示されてプログラムが失敗しました。しかし、PC では同様のコード ( doInBackground() の内容) がうまく機能します。正常に動作しているということは、別のコンピューターで KNX 接続 UDP パケットを受信できることを意味します。
Android デバイスでは、wifi 経由で単純な UDP パケットを送信できます。これは、wifi 接続と Android Java の基本コードが機能していることを意味します。
経験豊富な人が私のコードを調べて、どこに問題があるかアドバイスをくれますか? calimero API を使用したコードの一部は正しいですか? それは私にとって非常に役に立ちました。Calimero API は Android OS で動作しますか? 誰もそれを経験したことがありますか（ここのフォーラムの投稿によると、私はそう思います）。
