Hi All,
I need to send asynchronous calls to the server. During network
connection this works fine. How ever if i disable my LAN from Network
connections android will through a socket exception after the
specified timeout for that particular call. Now the issue that i face
is the time out happens in a synchronous manner. Though both the calls
has been started in a thread the timeout is not happening at the same
time. If i keep the timeout as 20sec i am getting a socket exception
for the first call after 20 sec and after the next 20 sec i get the
timeout for the next call. Why is this happening..? I am not opening
two connections asynchronously in this case. I am attaching a sample
code that can replicate the above scenario
package and.httptest;
import java.net.HttpURLConnection;
import java.net.URL;
import android.app.Activity;
import android.os.Bundle;
public class htptest extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Thread th=new Thread(httpconn2);
th.start();
Thread th2=new Thread(httpconn1);
th2.start();
}
static Runnable httpconn1=new Runnable() {
@Override
public void run() {
// TODO Auto-generated method stub
try{
HttpURLConnection httpCon=null;
URL url_ContentList = new URL("http://www.google.com";);
httpCon=(HttpURLConnection)url_ContentList.openConnection
();
System.out.println("Before connecting to
server !!!!!!!!!!!!!!!!! ");
httpCon.setRequestMethod("GET");
httpCon.setConnectTimeout(20000);
httpCon.setReadTimeout(10000 /* milliseconds */);
System.out.println("time out is"+httpCon. getConnectTimeout
());
httpCon.connect();
System.out.println("Response code is
resp1"+httpCon.getResponseCode());
}
catch(Exception e)
{System.out.println("exp is"+e);}
}
};
static Runnable httpconn2=new Runnable() {
@Override
public void run() {
// TODO Auto-generated method stub
try{
HttpURLConnection httpCon=null;
URL url_ContentList = new URL("http://www.bing.com";);
httpCon=(HttpURLConnection)url_ContentList.openConnection
();
System.out.println("Before connecting to
server !!!!!!!!!!!!!!!!! ");
httpCon.setRequestMethod("GET");
httpCon.setConnectTimeout(20000);
httpCon.setReadTimeout(10000 /* milliseconds */);
System.out.println("time out is"+httpCon. getConnectTimeout
());
httpCon.connect();
System.out.println("Response code is
resp2"+httpCon.getResponseCode());
}
catch(Exception e)
{System.out.println("exp is"+e);}
}
};
}
Please correct me if i am wrong
