Introducing Stormy
2:46We are going to build a simple and fun weather app called Stormy that gets the current weather conditions from a free service provided by Dark Sky.

Hi, I'm Ken.
0:09
I've an exciting project for
us to work on for this course.
0:11
One of my most used
apps is my weather app.
0:14
Now, I've tried several different ones,
on a number of different devices.
0:17
And while I've liked some,
none have been exactly what I've wanted.
0:21
Or maybe they've worked well,
but they don't look so good.
0:25
This is a great opportunity
to build our own.
0:29
As luck would have it,
getting weather data from the Internet,
0:32
and displaying it in an application
is a great learning experience.
0:35
These days most apps have some online
component, which requires us to get
0:40
familiar with sending and receiving
data over device's network connection.
0:44
I'm going to assume that you're
comfortable with the concepts covered in
0:50
our previous Android courses.
0:53
If you haven't taken our other courses,
check the prerequisites
0:55
list in Teacher's Notes, and complete
those courses prior to starting this one.
0:58
Let's get started.
1:03
Our user interface will
be relatively simple.
1:04
Once again, we have some great design
mock-ups to work from, thanks for
1:08
our amazing designers here at Treehouse.
1:11
We'll call this app Stormy,
1:14
and it will simply display current weather
conditions for a hard coded location.
1:15
Stormy will load fresh data
each time we run the app, and
1:20
we'll also add a refresh button.
1:23
We'll use the Dark Sky service for
our stormy app.
1:26
This service provides weather data for
developers, is fairly easy to use, and
1:29
powers some popular weather applications.
1:34
If we scroll down here and click on
the Dark Sky API link down in the footer,
1:36
and scroll down here on
their page a little bit,
1:41
We can find a list of some of
the organizations that rely on their data.
1:49
This service is pretty reliable, and
1:52
as we see at the top of this page,
It's free to get started.
1:54
Thanks, Dark Sky.

A typical weather app will
detect your location and
2:02
provide location-specific
weather automatically.
2:05
However, the focus of this course
is to learn about networking.
2:08
As such, Stormy will not
automatically detect our location.
2:13
We'll just use a specific location and
hard code it into the application.
2:17
Hard coding simply means we'll
type the location coordinates
2:21
directly into the app.
2:25
Adding location detection functionality
to the app would be an easy feature
2:27
enhancement to do later on.
2:31
And I encourage you to try
it once the app is finished.
2:33
Before we dive into Stormy, I'm going
to ask you to warm your brain and
2:36
fingers with a quick code challenge.
2:39
Once you're finished, meet me in
the next video and we'll get started.
