Back to previous activity having a dialog box in android

Issue

I have an android application with 2 screens. And I set a dialogue box while going from first screen to second screen. My code is:

@Override
        protected void onPreExecute() {
            super.onPreExecute();
            pDialog = new ProgressDialog(MainActivity.this);
            pDialog.setTitle("Please wait");
            pDialog.setMessage("Authenticating User");
            pDialog.setIndeterminate(false);
            pDialog.setCancelable(true);
            pDialog.setCanceledOnTouchOutside(false);
            pDialog.show();

            Intent it = new Intent(MainActivity.this, SecondActivity.class);
            it.putExtra("invoiceid", invc);
            it.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK); 
            startActivity(it);
            //finish();

        }

When running code, On clicking the back button it shows the dialogue box and goes to the first screen. Now I want to show the first screen directly on clicking the back button without showing the dialogue box.How is it possible?

And how to clear the first screen if there is a text box in it ?

Solution

Try pDialog.dismiss() before startActivity(it);
If you want to clear any data in any TextBox in the first Activity set text to that EditText "" before shifting any activity it will clear the data at EditText.
