We previously added a FUEL_LEVEL to our spacecraft. Now in FlightActivity,

We previously added a FUEL_LEVEL to our spacecraft. Now in FlightActivity, we want to get the value that we put in the Intent. Start by declaring an Intent variable and getting the Intent used to start this Activity.

FlightActivity.java 
import android.os.Bundle;

public class FlightActivity extends Activity {

  public int mFuelLevel = 0;

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

    // Add your code below!
    Intent intent = getIntent();
    intent.getStringExtra("FUEL_LEVEL");


  }
}

Step one:

Intent intent = getIntent();

Step two: Change the String to an int and add a defaultValue -1

int name = intent.getIntExtra("FUEL_LEVEL", -1);

Hope this helps! :)

It looks like you're on the 2nd step, getting the fuel level from the intent. You should note that the getExtra methods all use 2 argument, the 2nd being a default value. Also there are different getExtra methods that each return a different type and you should use the one that matches the type of data you're retrieving. Here it's an int.
