Courses Plus Student 1,070 PointsI'd like to use the getIntExtra method but am unsure how to use it.
I haven't used this method before. Just not sure how to code it.
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();
String mFuelLevel = intent.getIntExtra(FUEL_LEVEL, int defaultValue);
}
}

According to the code challenge it should be "FUEL_LEVEL" with the quotemarks. The second argument is an int number or variable for the default value, which the challenge states should be -1. So the code should look like:
mFuelLevel = intent.getIntExtra("FUEL_LEVEL", -1);

16,570 PointsThanks for this answer, but I have a question.... In the video. the value type String was used in the name variable(String name =....) Why didnt you do?: int mFuelLevel = intent.getIntExtra("FUEL_LEVEL", -1);
Was because mFuelLevel is already mentioned or what?

56,413 PointsThe variable begins with an 'm' prefix which means it's a member variable that's declared further up in the code near the start. It's already declared as type int. In this challenge the extra is passing a number value, not a string value like in the prior video.
