I don't understand this question. What is the default value and what is the "name"?

s

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");
  }
}

HI there,

You're pretty much there with your code. However, you've called getStringExtra, where you want to pull an integer through from the other activity. The "FUEL_LEVEL" string is a key to obtaining the integer. So, use getIntExtra instead. Pass in the key, as you have done, but also provide a default value, in case the retrieval fails, so you need to give a second parameter, which is an integer. Use -1, perhaps. Set mFuelLevel to the retrieved value.

This looks like:

    Intent intent = getIntent();
    mFuelLevel = intent.getIntExtra("FUEL_LEVEL", -1);

I hope that helps.

Steve.
