Textwatcher - Different Last Char Situations

Long story short I am facing this problem: I am attaching a textwatcher to an edittext. As soon as "1" is the last char written on it, that should be replaced with the letter "a". But here is the problem: I'd like as soon as "a" is also the last char written on the edittext (user pressed "a"), EXCEPT THROUGH THE PREVIOUS METHOD, some things to be done. But as I test it and type "1", that is converted to "a" normally and the things I mention are also done. I can't seem to find a way to overpass this, can any suggestions be given? Thanks a lot. I use:

public void afterTextChanged(Editable s) {
    //TODO Auto-generated method stub
    if (s.length() > 0 && s.toString().charAt(s.length() - 1) == '1') {
        current_string = s.toString().substring(0, (s.length() - 1));
        et.setText(current_string + "a");
        length = s.length();
        et.setSelection(length);
    }
    else if (s.length() > 0 && s.toString().charAt(s.length() - 1) == 'a') {
        //do some things
    }

Do you mean.

1)when user enters the 1 in end it should replace by 'a'. 2)when user enters 'a' separately (not converted by the step 1) it should do something else

amount1.addTextChangedListener(new TextWatcher() {

            int flagg;

            public void onTextChanged(CharSequence s, int start, int before,
                    int count) {

                System.out.println("flagg"+s+"#"+flagg );
                if (s.length() > 0  && s.toString().charAt(s.length() - 1) == '1' )
                {   System.out.println("Converting and doing NOthing");
                    flagg=1;
                    String current_string = s.toString().substring(0,(s.length() - 1));
                    amount1.setText(current_string + "a");
                    int length = s.length();
                    amount1.setSelection(length);

                } 
                else if (s.length() > 0     && ( s.toString().charAt(s.length() - 1) == 'a') && flagg == 0 )  {
                    System.out.println("Staying same and doing Something");

                    amount2.setText(amount2.getText().toString() + "Z");
                    // do some things
                }

            }

            @Override
            public void beforeTextChanged(CharSequence s, int start, int count,
                    int after) {

                if (start != 0) {

                    if ((s.toString()).substring(s.length() - 1).equals("a")) {
                        flagg = 1;
                    }
                    if ((s.toString()).substring(s.length() - 1).equals("1")) {
                        flagg = 0;
                    } else {
                        flagg = 0;
                    }

                }

            }

            @Override
            public void afterTextChanged(Editable arg0) {

            }
        });

//new flagg is set in if condition

try this

public void afterTextChanged(Editable s) {

if (s.length() > 0 && s.toString().charAt(s.length() - 1) == 'a') {
       //do some things
}
if (s.length() > 0 && s.toString().charAt(s.length() - 1) == '1') {
    current_string = s.toString().substring(0, (s.length() - 1));
    et.setText(current_string + "a");
    length = s.length();
     et.setSelection(length);

}
