Not sure how to get it right. I used int mFuelLevel = intent.getIntExtra("FUEL_LEVEL") but its showing error.

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();
    int mFuelLevel = intent.getIntExtra("FUEL_LEVEL");

      if(mFuelLevel == 0){
        mFuelLevel = -1;
      }


  }
}

Hi Priyanka,

getIntExtra takes a second argument which is the default value. So you should pass in -1 as the 2nd argument and take out the if statement that you're doing below that.

Also, you don't have to declare mFuelLevel as an int. It's a field on the class and has already been declared an int.
