Answer 1

In AsyncTask you have to notified in onPostExecute method:

So use this:

@Override
    protected void onPostExecute(String result) {
        // TODO Auto-generated method stub
        super.onPostExecute(result);
        Toast toast = Toast.makeText(YourActivity.this, "Message Here", duration).show();
        pDialog.dismiss();

    }

It also depends on your Response that which type of message do you want to display.

If you are not using AsyncTask then you can also use Handler.

Answer 2

You can show the toast message in the onPostExecute() method of your async task.

Answer 3

You can simply display a toast in onPostExecute

 @Override
        protected void onPostExecute(String result) {
            // TODO Auto-generated method stub

            super.onPostExecute(result);
            Toast toast = Toast.makeText(context, text, duration);
             toast.show();
            pDialog.dismiss();

        }

Answer 4

on the your asynctask

@Override
protected void onPostExecute() {



    Toast toast = Toast.makeText(getApplicationContextt, "File Uploaded", Toast.LENGTH_LONG).show();

}

public class MainTest extends AsyncTask<Void, Void, Boolean> {

        @Override
        protected void onPreExecute() {
            pDialog = new ProgressDialog(DataAcceptActivity.this);
            pDialog.setMessage("Loading..");
            pDialog.setIndeterminate(true);
            pDialog.setCancelable(false);
            pDialog.show();
        }

        @Override
        protected Boolean doInBackground(Void... params) {

            postImageData();

            return true;
        }

        @Override
        protected void onPostExecute(Boolean result) {
            // TODO Auto-generated method stub

            super.onPostExecute(result);
            // data=jobj.toString();
             if(result)
         {
          Toast.makeText(_context , "Image uploaded.." , Toast.LENGTH_LONG).show();
     }
    /* else
     {
        Toast.makeText(_context , "Image is not uploaded.." , Toast.LENGTH_LONG).show();
     }*/
        if(pDialog.isShowing())pDialog.dismiss();
       }

    }

In your code addding some changes in onPostExecuteMethod

 public class MainTest extends AsyncTask<String, Integer, String> {
    @Override
    protected void onPreExecute() {
        pDialog = new ProgressDialog(DataAcceptActivity.this);
        pDialog.setMessage("Loading..");
        pDialog.setIndeterminate(true);
        pDialog.setCancelable(false);
        pDialog.show();
    }

    @Override
    protected String doInBackground(String... params) {

        postImageData();

        return null;
    }

    @Override
    protected void onPostExecute(String result) {
        // TODO Auto-generated method stub
        super.onPostExecute(result);
       if(pDialog.isShowing()){
        // data=jobj.toString();
         pDialog.dismiss();
     }
       Toast toast = Toast.makeText(context, text, duration);
         toast.show();
    }

}
