Android：模拟器无法解析本地工作站的主机名

Question

I'm trying to connect to a web app running my computer from the android emulator using the apache httpClient .

HttpPost post = new HttpPost("http://dev.example.com:8443/gatekeeper/rs/authenticate/login");
post.setHeader("Content-type","application/x-www-form-urlencoded");
post.setEntity(new UrlEncodedFormEntity(formparams));
HttpClient client=new DefaultHttpClient();
response = client.execute(post);

I do have the required android manifest configuration as below

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

I did check I can access the internet from the browser on the emulator. I can not access the app URL from the browser as well. My application also fails with an error

java.net.UnknownHostException: Unable to resolve host "dev.example.com": No address associated with hostname

My application works fine when used with IP address of my computer. I also have entry in my hosts file

192.168.1.8 dev.example.com

What can I be missing here? It looks like android emulator can't look in to my hosts file to resolve the host name!

Please check the Connectivity programitically before calling for response

or If there is no response the also this exception is thrown
