How do I do this? What are they asking me to do?

Hey Farouk,

This is the code we were given:

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!

  }
}

I'll try to make the instructions a bit easier to understand. Let's look back at the actual project we were building. We had a main activity and we linked it to another activity through the use of intents. Remember that? And we could pass data through activities by using putExtra() and receiving the string data by using getStringExtra().

In this challenge, basically it's saying that we already have a main activity and the code that we currently are on is the second activity. We want to receive the data we passed through our intent in the main activity.

In the onCreate() method, we simply create a new intent and then get the intent.

Intent intent = getIntent();

Does this look familiar?

For the second part of the challenge, we are now going to receive the intent we passed. However this time it is an int and NOT a string. Ben linked you to the intent documentation so you can see what parameters need to be passed in. We use the getIntExtra() method and pass it 2 values. The first is the key string which is "FUEL_LEVEL" as written in the instructions. The second is a default int value if no value is receive from our getIntExtra() method. The value we have to write is written in the instructions. We then store this int value in the mFuelLevel variable which is already initialized.

I attached the answer for your reference and in case you are still stumped:

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);

  }
}

Hope that helped and happy coding,

Kevin
