Android Build an Interactive Story App (Retired) Intents and Multiple Activities Getting Data from an Intent

Intents and Multiple Activities -> Getting Data from an Intent challenge. Can't figure out the code.

So here's my code. The challenge says:

"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");
  }
}

All you need for the first task in the code challenge is to get the intent, which you have correct. Just remove intent.getStringExtra("FUEL_LEVEL");

Jack's correct, but if you're continuing to the next part of that code challenge and do need that line, you'll have a couple of issues. What you really want is:

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

Notice you need to assign it to a variable (mFuelLevel), you need to use getIntExtra instead of getStringExtra (because the value is an integer), and you have to pass in a -1 parameter too, which is the default value. Hope that helps!

Thanks ! But how do we suppose to know that we have to use that -1? I think the vídeo should have mentioned that.

Thank you for helping us with the answer. However, what does the -1 mean?
