Android 开发常见问题总结

问题：Android之NetworkOnMainThreadException异常
解决方式 ，使用多线程，异步加载的方式加载数据：

    /**     * 异步的Post请求     * @param urlStr     * @param params     * @param callBack     * @throws Exception     */    public static void doPostAsyn(final String urlStr, final String params                                  ) throws Exception    {        new Thread()        {            public void run()            {                try                {                    String result = doPost(urlStr, params);                   // if (callBack != null)                   // {                  //      callBack.onRequestComplete(result);                   // }                } catch (Exception e)                {                    e.printStackTrace();                }            };        }.start();    }

问题：Android真机（手机）访问本机的tomcat导致，
java.net.ConnectException: failed to connect to localhost/127.0.0.1 (port 8080)
问题原因：Android真机（手机）和本机的tomcat不在同一个网段。

解决方式：在本机用（360免费wifi）分享一个无线网，Android真机（手机）连接分享的无线网。
