We've updated our LaunchActivity to include a fuel level (fuelLevel) for the spacecraft. This value needs to be passed to the FlightActivity. Add the code to pass this value along via the Intent. Use the key "FUEL_LEVEL"
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class LaunchActivity extends AppCompatActivity {
public Button launchButton;
public int fuelLevel;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_launch);
// fuelLevel is set elsewhere.
// Code ommitted for brevity!
launchButton = (Button)findViewById(R.id.launchButton);
launchButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// Add your code in here!
Intent intent = new Intent(LaunchActivity.this, FlightActivity.class);
startActivity(intent);
}
});
}
}

Happy coding!!

2,743 PointsI don't understand this at all. Where does the "FUEL_LEVEL" all of a sudden come from? I know the challenge told me to write that, but doesn't it need to reference something in the code for it to work? Or can I just make up words and it's all fine and dandy?
I don't think I really understand the concept of passing a value through intent yet, but the answer seems really odd to me and (with my current understanding, or lack thereof) makes more sense if it was:
intent.putExtra("fuelLevel", FlightActivity); instead of intent.putExtra("FUEL_LEVEL", fuelLevel);
So passing "fuelLevel" -> FlightActivity as explained in the challenge ("This value needs to be passed to the FlightActivity.") I've watched the video multiple times and googled it, yet I keep falling back to the same conclusion. What key point am I missing?
