This is my code:
public void onClick(View arg0) {
try{
   new DownloadFilesTask().execute("url3");//url3 is not used in Connect()
        }catch(Exception e){
            e.toString();// I can't catch an exception!
        }
    }
   };//on click;
private class DownloadFilesTask extends AsyncTask<String, Integer, Long&gt; {
    protected Long doInBackground(String... urls) {
     Connect();
     long i = 10;
     return i;
    }
 
}
Target OS is Android 2.2. Aplication crashing and I can't catch an exception. Please help.

- what is happening in DownloadFilesTask.execute(String) ?
- can you catch something there?

I think you want to display something in the doInBackground method.
The UI runs in another thread then your AsyncTask.
Try to do all UI work in the onPostExecute method.

...or bring the UI-Part back to the UI-Thread.
