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

How to receive int as in intent?

I'm confused in bringing back an int as an intent.

import android.os.Bundle;

public class FlightActivity extends Activity {

  public int mFuelLevel = 0;

  protected void onCreate(Bundle savedInstanceState) {

    // Add your code below!
    Intent intent = getIntent();
    mFuelLevel = putExtra(FUEL_LEVEL, -1);

Hi Shiv,

You're very close with that.

You've declared a new Intent and are trying to extract the extra from it. You've not selected the correct method, though. We're getting (an integer), not putting. And the FUEL_LEVEL isn't a variable name, it is a key in a key/value pair, so it is a string; you'll need to surround it with double-quotes.

So, your code should end up with something like:

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

I hope that helps.


Thank you so much Steve. I have been stuck at the same place for about a day I guess. On point explanation which cleared all my doubts. Thanks again :)

Hey, no problem! Don't struggle for a whole day! Just shout in here, we'll come and help. If you get no joy, remember you can @ mention me directly.

Yes, I was actually trying and trying and trying to do it on my own, tried all the methods I could see on the official website of android which said int. Then I saw that I can look for help here too, so I immediately asked. Thanks for the support.
