Unable to resolve error in Qualtrics Initialization

Question

I'm a newbie in Android development. I'm getting an error when I'm trying to initialize an instance of Qualtrics. I have created the intercept ID and Creative ID for the Qualtrics survey that I'm using here. Here's the code for MainActivity.java:

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        Qualtrics.instance().initialize("abc", "ZN_51hH0BfnHQUZF", "SI_d50cthAy2SEFO",this);

        FloatingActionButton fab = (FloatingActionButton)findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
            Qualtrics.instance().evaluateTargetingLogic(new MyCallBack());
            }
        });
    }

This is the error I keep getting in the logcat:

Does anyone have any idea why this error is occurring?
