In my activity class I am unable to open a request or set active session using 'this'. My activity is a child of another activity and that seems to be the only difference between it and the login sample given by facebook. When I use 'this' I get this error:

I have tried using getParent() in its place however the page redirects to the parent and does not call the callback. Is there a reason I cannot use this and a way to fix it?
EDIT: code
This is what gets called once the button is clicked to login to facebook:
public void getEmail() {
StatusCallback callback = new StatusCallback() {
public void call(Session session, SessionState state, Exception exception) {
if (session.isOpened()) {
sendRequests();
} else if (exception != null) {
AlertDialog alertDialog;
alertDialog = new AlertDialog.Builder(getParent()).create();
alertDialog.setTitle(getParent().getString(R.string.login_fail));
alertDialog.setMessage(exception.getMessage());
alertDialog.show();
mSession = createSession();
}
}
};
Session session = Session.getActiveSession();
if (session == null) {
session = new Session(this);
if (session.getState().equals(SessionState.CREATED_TOKEN_LOADED) || session.getState().equals(SessionState.CREATED)) {
session.addCallback(callback);
session.openForRead(new OpenRequest(this));
Session.setActiveSession(session);
}
} else {
Session.openActiveSession(this, true, callback);
}
}
