i can't pass this challenge

Bummer! The first parameter for the Intent constructor must be the current context (you can use 'LaunchActivity.this')

LaunchActivity.java 
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class LaunchActivity extends Activity {

  public Button mLaunchButton;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_launch);

    mLaunchButton = (Button)findViewById(R.id.launchButton);
    mLaunchButton.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {
        Intent intent = new Intent(this, LaunchActivity.class);


        // Add your code in here!

      }
    });
  }
}

Hi, it's asking you to updated the onClick method for mLaunchButton.

Once clicked, it will launch FlightActivity. The first part of the task asks you to write the intent while the second asks you to start it.

You are getting the error because you have supplied 'this' to the new intent constructor. That would be fine but because you are in an anonymous method (new View.Clicklistener() {it's anonymous in here}. So the message tells you that you have to specify that the context you are supplying it is specifically the LaunchActivity.this.

Solution:

Intent flightIntent = new Intent(LaunchActivity.this, FlightActivity.class);
startActivity(flightIntent);

Hope that helps.
