"The code below has been modified to add a "relaunch" button. In the onClick() method for this button, finish this current Activity so that the previous Activity is resumed."

So it's asking you to go into onClick() and add the code that will stop/remove the current activity. It should just be one line of code.

Hi Josh,

You want your code to look like this:

       mRelaunchButton = (Button)findViewById(R.id.relaunchButton);
        mRelaunchButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                finish();

Spoiler Alert:

import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class LandingActivity extends AppCompatActivity {

    public Button relaunchButton;

    // Some previous code omitted for brevity

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_landing);

        // Some previous code omitted for brevity

        relaunchButton = (Button)findViewById(R.id.relaunchButton);
        relaunchButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
              finish();  
            }
        });
    }
}
