Web サービスに接続するはずの Android クライアントがクラッシュします。メインスレッドで HTTP に接続していることはわかっていますが、問題を解決する 2 行を (一時的に) 追加しました。AsyncTask は後で追加します。

主な活動：

protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();

        StrictMode.setThreadPolicy(policy);

これらの例外が何によって引き起こされているのか本当にわかりません...

アプリケーション マニフェストに Internet のアクセス許可を追加していただければ幸いです。

<manifest xlmns:android...>
 ...
 <uses-permission android:name="android.permission.INTERNET"></uses-permission>
</manifest>

編集:localhost:8080サービスをホストしているシステムのアドレスとして 指定して、Web サービスに接続しようとしています。Android エミュレーターは、仮想マシン (QEMU) 内で実行されます。したがって、システムのループバックアドレスではなくlocalhost:8080、エミュレーター自身のループバックアドレスになります。

そのため、Windows の CommandPrompt に移動してシステムの IP アドレスを取得するかhttp://10.0.2.2:8080/...、localhost.
