ASPで作成し、現在実行中の Web サービスにアプリを接続しようとしていlocalhostます。Coordonateアプリは、3 つの整数を受け取るメソッドにアクセスしようとしています。

コードとLogCatを提供しました。私は Web サービスに不慣れであることを言及する必要があります。

どんな助けでも大歓迎です！乾杯！

Try replacing localhost with IP address of your system in following line.

private static final String URL = "http://localhost:49934/Service1.asmx";

This might help you.

As even if you are testing it on emulator running on same system then also both asp.net and android have different IP for localhost maybe 10.0.2.2 in some cases.

以前も同様の問題がありました。Android アプリケーションからローカル .NET Web サービスを呼び出す方法 をご覧ください。

それが役に立てば幸い
