Now set mFuelLevel the the value from the Intent. Check the Intent documentation if you need help finding the correct me

I couldn't find a way to do that.

Help please

FlightActivity.java 
import android.os.Bundle;

public class FlightActivity extends Activity {

  public int mFuelLevel = -1;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_flight);

    Intent intent = getIntent();

    String mFuelLevel = intent.getStringExtra("FUEL_LEVEL", mFuelLevel);

  }
}

Hi,

mFuelLevel is an Int type

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.getIntExtra("FUEL_LEVEL", -1);

  }
}

Two things:

  1. mFuelLevl is already declared as an int, so you can't declare a String with that name. 
mFuelLevel = intent.getStringExtra(String [KEY NAME], defaultValue);
  1. You are using .getStringExtra, but the value you are trying to get is an int. Instead, use .getIntExtra().
mFuelLevel = intent.getIntExtra(String [KEY NAME], defaultValue);

All should be fine after that ^^

Thanks Mikael,

Your answer was pretty good. Instead of giving me the fish you showed me how to fish.

:) Happy Coding

There seems to be a slight bug in the challenge though, in that you can pass the challenge without assigning the return value of intent.getIntExtra("FUEL_LEVEL", -1) to mFuelLevel.

The full correct answer is: 

import android.os.Bundle;

public class FlightActivity extends Activity {

  public int mFuelLevel = -1;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_flight);

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


  }
}
