I have an application of conversion, it uses navigation drawer but when you don't type the amount it throws an error with the method "setError()" for the EditText that is not filled, however there is a but,
when I open the Navigation Drawer the message of the error remains on the screen on the navigation drawer and I don't know how to dismiss the error when the drawer is opened.
Whenever navigation drawer is opened Just call
editText.setError(null);
