Remove toast from Void doInBackground(Void... mApi) \
You cannot show toast on doInBackground() method here because there is dialog already running, you have need to remove toast from here and add on onPostExecute( ). \

```
  @Override		protected void onPostExecute(Void result) {			super.onPostExecute(result);			pDialog.cancel();			Toast.makeText(MainActivity.this, "Email send", Toast.LENGTH_LONG)					.show();		}
```
