i run the code.

The first error is ..illegal start on an expression on all import package statement.

RandomTest.java 
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import java.util.Random;

public class RandomTest extends AppCompatActivity {

  private TextView mFactTextView;
  private Button mShowFactButton;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.Layout.activity_fun_facts);

    mFactTextView   = (TextView) findViewById(R.id.factTextView);
    mShowFactButton = (Button) findViewById(R.id.showFactButton);  

    View.OnClickListner Listener = new View.OnClickListener() {
      @override
      public void onClick(View v) {
        String[] facts = { "example",
                           "example",
                           "example",
                           "example",
                           "example",
                           "example",
                           "example",
                           "example"} 

        String fact = "";

Random randomGenerator = new Random();
int randomNumber = randomGenerator.nextInt(facts.Length);
fact = randomNumber + "";        

        mFactTextView.setText(fact);

      }        
    }

You don't need to create an Activity for the challenge. Just start with the following two lines and then add on to them for tasks 3 and 4:

Random randomGenerator = new Random();
int randomNumber = randomGenerator.nextInt();

Thank you Raeen..it worked. I am just wondering why the program i wrote is giving an error on import statement as an illegal start of an expression.
