targetはAndroid2.3.4、API 10向けにビルドして試した。

リクエストができているかの確認は、EM::HttpServerで見た
gem install eventmachine_httpserver


#!/usr/bin/env ruby

require 'rubygems'

require 'eventmachine'

require 'evma_httpserver'



class Handler  < EM::Connection

  include EM::HttpServer

 

  def process_http_request

    res = EM::DelegatedHttpResponse.new(self)

    puts "request_method : #{@http_request_method}"

    puts "path_info : #{@http_path_info}"

    puts "query_str : #{@http_query_string}"

    puts "post_content : #{@http_post_content}"

    res.status = 200

    res.content = "こんにちは"

    res.send_response

  end

end



EM::run do

  EM::start_server("0.0.0.0", 8080, Handler)

  puts "http server start, prot 8080"

end
