Answer 1

Pass in and use the context from LoginPage. Also, use the 101010 button to format your code as code in your posts.

hi, you can go up by using try catch mechanism where in your catch place your toast message and u can do it also by asynchronous task, here simple code

private class Task_News_ArticleView extends AsyncTask<Void, Void, Void> {
        private final ProgressDialog dialog = new ProgressDialog(
                Bru_Sports_View.this);

        // can use UI thread here
        protected void onPreExecute() {
            this.dialog.setMessage("Loading...");
            this.dialog.setCancelable(false);
            this.dialog.show();

        }

        @Override
        protected Void doInBackground(Void... params) {
            try {
                //here the condition to check login details

                }
            } catch (Exception e) {

            }
            return null;

        }

        protected void onPostExecute(Void result) {

            if (this.dialog.isShowing()) {
                this.dialog.dismiss();

            }
        }
    }

and u can also use try,catch in catch block you can place your toast message with finsih() method
