Handling interrupted exception of AsyncTask in Android?

Question

Hi,

I am using AsyncTask in my application.

The problem is that when server is down the AsyncTask throws an Interrupted exception. How to track that whether server is down or not.

`

HttpGet httpget = new HttpGet(urls[i]);

ResponseHandler<String> responseHandler = new BasicResponseHandler();

content = httpClient.execute(httpget, responseHandler);

`

This same problem also occurs when the handset is kept idle for some time then keyguard gets lock and I suppose that WI-FI also gets disabled. So, when I enable the keyguard and if my application is in foreground then it gives the same exception.

Can someone please let me know what should I do in order to remove this exception? Is there in solution to this.

Please let me know what can be done.

Regards

Sunil

Basically, before every url connexion, you could test the network availability by doing something like that :

if (connectivityManager.getActiveNetworkInfo() != null && connectivityManager.getActiveNetworkInfo().isAvailable()) {
//do your stuff
}

And you could also ping the server with a short timeout to check if the server is available.
