I am having a problem executing an url via httpget in android.

try 
    {   
        DefaultHttpClient client = new DefaultHttpClient();
        HttpGet getURL = new HttpGet("http://www.example.com/index.php?text=x");
        client.execute(getURL);
        Toast.makeText(this.getBaseContext(), "I'm here", Toast.LENGTH_LONG).show();
    } catch (Exception e) {
        Toast.makeText(this.getBaseContext(), "Code Failed:" + e.getLocalizedMessage(), Toast.LENGTH_LONG).show();
        }

For some Reason my app wil show a Toeast with the message: “Code Failed: Null”.
I just want to execute an URL. When the URL is called my php file will update a record in the database. I just want to update/insert databases in my mysql database. So parsing json/xml/other response is not necessary.

If I show my exceptions in the logcat, this is what I see:

you should make network call on main UI thread. following is the definition of the exception:

The exception that is thrown when an application attempts to perform a
networking operation on its main thread.

This is only thrown for applications targeting the Honeycomb SDK or
higher. Applications targeting earlier SDK versions are allowed to do
networking on their main event loop threads, but it’s heavily
discouraged.
