Answer 1

public void clear(){

String text = (yourEditText.getText().toString);
if(!(text.equals("")))
yourEditText.setText(text.subString(0,text.length-2));
}

a better one could be

Editable editableText = yourEditText.getEditableText();
            int length = editableText.length();
            if (length > 0) {
                editableText.delete(length - 1, length);
            }
