Showing Progressdialog in asyncTask

Question

I have an async task for getting result from web services. I my class I've tried to show and hide a progress dialog. but in the middle of getting the result from web services some error occur as you can see in log cat. I think the problem is that I'm trying to get the result in async mode and then finishing current activity. since my async task is getting my activity in the constructor and using that for showing ProgressDialog, after finishing the activity and trying to show another progress dialog in async task this problem occurred. What should I do?

public class AsyncCallWs extends AsyncTask<String, Void, String> {

    private ProgressDialog dialog;
    public String methodName="";
    private WebService ws;
    private ArrayList<ServiceParam> paramsList;
    private boolean hasParams; 
    private Activity activity;
    private OnTaskCompleted listener;

    public AsyncCallWs(Activity activity,OnTaskCompleted listener,String methodName) {
        xLog.position();
        try {
            this.methodName = methodName;
            this.activity = activity;
            hasParams = false;
            this.listener = listener;
        } catch (Exception e) {
            xLog.error(e.getMessage());
        }
    }

    public AsyncCallWs(Activity activity,OnTaskCompleted listener,String methodName,ArrayList<ServiceParam> params) {
        xLog.position();
        try {
            this.methodName = methodName;
            this.activity = activity;
            this.paramsList = params;
            hasParams = true;
            this.listener = listener;
        } catch (Exception e) {
            xLog.error(e.getMessage());
        }
    }

    @Override
    protected void onPreExecute() {
        this.dialog = new ProgressDialog(activity);
        this.dialog.setMessage("Loading...");
        this.dialog.show();
    }

    @Override
    protected String doInBackground(String... params) {
        //Do something...
    }

    @Override
    protected void onPostExecute(String result) {
        xLog.position();

        if (this.dialog.isShowing()) {
            this.dialog.dismiss();
        }
        listener.onTaskCompleted(result,methodName);
        xLog.info("Output of current AsyncTask is:"+ result);

    }
}

You need to call this.dialog.dismiss(); before you finish your Activity

The dialog is not in my activity, It's in async task class and this.dialog is not recognized. – ehsan shirzadi Dec 11 '13 at 08:16
Then create a method that dismisses the `ProgressDialog` in `AsyncCallWs` and call it in your `Activity` before finishing it – Apoorv Dec 11 '13 at 08:18

You could use a headless fragment and do your async processing inside that instead of inside the activity.

There is a tutorial here: http://techbandhu.wordpress.com/2013/07/02/android-headless-fragment/
