Hi Arjun! The goal in the challenge is to set the int member variable: mFuelLevel.

Your problem seems to lie in this line of code:

 String name = intent.getStringExtra("-1");

Here you are attempting to set a string variable with a string value, when you really should be setting the int (mFuelLevel) by retrieving the int from the intent with intent.getIntExtra().

Try this:

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

Let me know if that helped!
