HttpUrlConnection.connect() Query - httpurlconnection

Question

After hours of trawling the internet and trying to make sense of the documentation I seem unable to find a resolution to this problem.
I have an application which is using an ASyncTask to connect to a server I have 3 addresses to "test" the connection.
Now the problem is when I use the Myconnection.connect() the background task just hangs if there is either no known address or a dead link.
How can I test this connection when with a dead link or dead server it hangs and does not receive any response
The errors in the Logcat are
07-02 12:47:13.101 13850-20562/nodomain.myapplication D/URL ERRORhttp://10.0.0.2/testdb/connection.php
07-02 12:47:13.339 13850-20562/nodomain.myapplication I/URL IS OK: [ 07-02 12:47:13.339 13850:20562 I/ ]Status : 200
07-02 12:47:13.344 13850-20562/nodomain.myapplication D/URL ERRORhttp://localhost/myPage.php
As you can see the only URL I get a response from is www.google.com
My code is below:
package nodomain.myapplication;
import android.os.AsyncTask;
import android.util.Log;
import org.w3c.dom.Text;
import java.io.BufferedWriter;
import java.io.IOException;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.io.UnsupportedEncodingException;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.URLEncoder;

public class bgWorker extends AsyncTask<Void, Integer, Void> {
#Override
protected Void doInBackground(Void... params)
{
String db_Username = "root";
String db_Password = "";
String db_Name = "testdb";
String url1 = "http://10.0.0.2/testdb/connection.php"; //DEAD? (NO RESPONSE)
(Program Hang until exception is called)
String url2 = "http://www.google.com"; //OK RESPONSE 200
String url3 = "http://localhost/myPage.php"; //NO RESPONSE
try {
getResponseCodes(url1);
getResponseCodes(url2);
getResponseCodes(url3);
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
#Override
protected void onProgressUpdate(Integer... values) {
}
private String encodeURLString(String value) {
String encodedString = "";
try {
encodedString = URLEncoder.encode(value, "UTF-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
return encodedString;
}
public static int getResponseCodes(String TheURL) throws MalformedURLException,IOException
{
URL oUrl = new URL(TheURL);
HttpURLConnection oHuC = (HttpURLConnection) oUrl.openConnection();
oHuC.setRequestMethod("HEAD");
int response = 0;
try{
oHuC.connect();
response = oHuC.getResponseCode();
if(response == 200)
{
Log.i("URL IS OK","");
}else{
Log.i("URL IS NOT OK","");
}
Log.i("", "Status : " + response);
}catch(IOException e){
Log.d("URL ERROR" + oUrl, "D");
}
return response;
}
}
Even with the IF statement testing the response for a 200 OK it only manages to interpret one response from the 3 URL due to the URL IS OK output.
