Estou criando o objeto Rastreador do Google Analytics a partir de uma atividade. O problema é que estou recebendo um erro na operação de conversão feita em this.getApplication (). Informe-me como criar um objeto rastreador a partir de uma atividade.

public void sengToGoogleAnalytics() {
    Tracker t = ((AnalyticsSampleApp) this.getApplication()).getTracker(TrackerName.APP_TRACKER);
    t.setScreenName(getString(R.string.memoryhome));
    t.send(new HitBuilders.AppViewBuilder().build());
}
