Question

I’ve this part of code:

public void onClickHandler(View a) {
    String pressed = null;
    String actual_text = null;
    String new_text = null;
    char last_char; //or char last_char = (Character) null; - the same problem
    int bla;

    pressed=((Button)a).getText().toString(); 

    EditText lifeView = (EditText) findViewById(R.id.edittext);
    actual_text = lifeView.getText().toString();

    bla=actual_text.length()-1;
    last_char = actual_text.charAt(bla);
}

And I’m solving the problem, that after pressed button I will get the error “The application has stopped unexpectedly. Please try it again.”

The problem is on the line “char last_char” — but I don’t know why, Eclipse does not report a fault too…

Answer 1

You need to initialize the char last_char;

Ex:

char last_char=' ';

or similar but not null.
