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!

  }
}

They are asking you to do two things:

  1. Declare an Intent

  2. Assign it the value, of the intent used to start the activity.

Which one of those are you unsure about, and did you watch the video before the quiz?

the second one ??!!

the first one is Intent intent = getIntent();

in fact this is the what they asked >>>?

Now set mFuelLevel the the value from the Intent. Check the Intent documentation if you need help finding the correct method to use. Use "FUEL_LEVEL" as the key and -1 as the default value.

There is a method called. Intent.putExtra(). Which takes a string for the key, and an int for a value. Use that, with the information you just referenced. Make sure to use your "intent" .

Sorry, you want to use 'getExtra'. Not put. The int is already there. You just have to get it out by key.

I changed to

mFuelLevel = intent.getExtra("FUEL_LEVEL",1);

but it said that there is a different method to get an int extra ?!!

It may require you to specify a default value. Add another integer into the parameters, you can use 0 or 1. Or whatever you want.
