public class SignUpActivity extends Activity {
public static final String TAG = SignUpActivity.class.getSimpleName();
protected SignUpCallback mSignUpCallback = new SignUpCallback() {
@Override
public void done(ParseException e) {
}
};
// onCreate() and other code has been omitted
protected void signUp(String username, String password) {
ParseUser newUser=new ParseUser();
newUser.setUsername(username);
newUser.setPassword(password);
newUser.signUpInBackground(mSignUpCallback);
}
}
}

Can you post the link to the challenge or let me know what the error is you are getting (and the question you're having a problem with).
Thanks,
Steve.

4,418 PointsHi Steve
Inside the done() method of the callback, add an if statement to check if the ParseException e is null. If it is not null, log the message "ERROR" using the Log.e() method. Don’t forget to use TAG as the first parameter!

57,712 PointsLooking at your error there, in particular this bit: ParseException cannot be converted to boolean if(e = null)
You're trying to assign null to e. Not test if e equals null. Try starting with if (e == null) - the double equals sign checks for equality, a single equals sign tries to assign values to variables.
Make sense?
Steve.

57,712 PointsIsn't your 'if' statement in there?
MUZ140772 Thomas Mushayi
4,418 PointsThis is my full code
thanks
public void done(ParseException e)
{
if (e == null){
//success
}
else{
Log.e(TAG , "ERROR");
}
}
});
}

57,712 PointsI can't see anything wrong with that. I can't check all the closing brackets, though.
What error is it giving you?
