java – (Android Studio) Error while running TapTargetSequence

Hello

I'm trying to do TapTargetSequence in Android Studio however this does not work and has an error.
In theory, it was running in the cardView2 and later on cardView3 but it does not work either.

My code

new TapTargetSequence (this)
.targets (
TapTarget.forView (findViewById (R.id.cardView3), "That's okay"),

TapTarget.forView (findViewById (R.id.cardView2), "You", "Up")
.dimColor (android.R.color.darker_gray)
.outerCircleColor (R.color.colorAccent)
.targetCircleColor (R.color.color_subtetli)
.textColor (android.R.color.holo_blue_dark)
)
.listener (new TapTargetSequence.Listener () {
// This listener will tell us when interesting events (tm) occur with respect to
// to the sequence
@Override
public void onSequenceFinish () {
// Yes
(TextView) findViewById (R.id.textView2)) setText (" n" + "Congratulations, you're educated now!");
}

@Override
public void onSequenceStep (TapTarget lastTarget, boolean targetClicked) {

}

@Override
public void onSequenceStep (TapTarget lastTarget) {
// performance action for the current target
}

@Override
public void onSequenceCanceled (TapTarget lastTarget) {
// boo
}
});

Error message – Even if I delete the @Override still does not work.

The compilation failed. see the compiler error output for more details.
