基本的にポート 8080 ですべてのリクエストをリッスンし、それらをコンソールに書き込む、非常に単純な Java サーバーを実装しました。

私のコードは一度、正常に動作します。ただし、サーバーを再起動するたびに、要求は 1 つしかかかりません。

サーバーコード:

public class RunServer {

    public static void main(String[] args) {
        final int port = 8080;
        final String path = "/android";
        try {
            HttpServer server = HttpServer.create(new InetSocketAddress(port), 0);     //Create the server to listen for incoming requests on the specified port
            server.createContext(path, new HttpHandler() { //Set a handler for     incoming requests to the specific path
                @Override
                public void handle(HttpExchange arg0) throws IOException {     //This method is called when new requests are incoming
                            InputStreamReader isr = new     InputStreamReader(arg0.getRequestBody(),"utf-8");
                            BufferedReader br = new BufferedReader(isr);
                            String query = br.readLine();

                            System.out.print(query);
                } });           
            server.setExecutor(null); //Default executor. Other executors may be     used to e.g. use a threadpool for handling concurrent incoming requests.
            server.start(); //Start the server.
        } catch (Exception e) {
            e.printStackTrace();
        }       
    }
}

このクライアントを使用してサーバーに投稿しています:

public class MyAsyncTask extends AsyncTask<String, String, Void>{
    HttpClient httpClient = new DefaultHttpClient();
    HttpPost httpPost = new HttpPost("http://192.168.1.5:8080/android");
    String s;
    @Override
    protected Void doInBackground(String... params) {
        // Building post parameters
        // key and value pair
        List<NameValuePair> nameValuePair = new ArrayList<NameValuePair>(2);
        nameValuePair.add(new BasicNameValuePair("email", "user@gmail.com"));
        nameValuePair.add(new BasicNameValuePair("message",
                "Hi, trying Android HTTP post!"));

        // Url Encoding the POST parameters
        try {
            httpPost.setEntity(new UrlEncodedFormEntity(nameValuePair));
        } catch (UnsupportedEncodingException e) {
            // writing error to Log
            e.printStackTrace();
        }

        // Making HTTP Request
        try {
            HttpResponse response = httpClient.execute(httpPost);

            // writing response to log
            Log.d("Http Response:", response.toString());
        } catch (ClientProtocolException e) {
            // writing exception to log
            e.printStackTrace();
        } catch (IOException e) {
            // writing exception to log
            e.printStackTrace();

        }
        return null;
    }

}
