We can't make an app without any resources! In this video we'll move the solitaire code into our Android project, and then we'll find some great card resources!

We've just covered a ton about Anko.
0:04
And Kotlin too for that matter.
0:07
I know this stuff can seem challenging,
but you're doing a great job at it.
0:09
And once you see your
finished solitaire app,
0:13
I'm sure you'll agree that
it was worth the challenge.
0:15
Anywho, let's get back
to our solitaire app.
0:17
First let's start fresh by closing
everything other than main activity.
0:21
And then deleting everything
in the onCreate function
0:28
except the call to super.
0:31
Next, before we can do anything involving
solitaire we'll need to get the code for
0:35
solitaire into our app.
0:39
To keep things simple let's just copy and
0:42
paste the code into a new package
inside our current package.
0:44
So right click on your package and
pick new Package and
0:49
for the name,
I'm going to pick no_Android.
0:55
But you can use whatever name you'd like.
1:01
I like this one because it reminds me
not to add any Android code to it.
1:04
Once we've got our new package,
all we need to do is copy and
1:08
paste all the code files for
our solitaire project Into this package.
1:11
If you don't already have the code files,
you can download a zipped folder of them
1:17
from the GitHub project linked
in the teacher's notes below.
1:20
So let's copy those files and then
paste them into our no_Android package.
1:24
And actually, we don't need the app.kt
file anymore, so let's delete it.
1:33
Next, to make our solitaire code
work with our Android code,
1:43
we'll need to add a package
directive to each of these files.
1:46
So starting with Card.kt,
let's add a couple lines at the top and
1:49
then add your package directive.
1:55
For me,
that's com.teamtreehouse.solitaire.
1:58
And notice that I didn't
add dot no android.
2:04
For this app, It's just a bit simpler
if everything is in the same package.
2:08
Now that does give us a warning,
2:13
that package directive
doesn't match file location.
2:15
But while the package directive and
the file location
2:19
are usually the same they're actually
two completely separate things.
2:22
So we don't need to worry
about this warning.
2:27
Now let's copy our package statement and
2:29
then go about adding it to
the rest of our solitaire files.
2:32
Finally let's right click on one
of the files tabs up here and
2:59
choose close all to clean up our windows.
3:03
Now that we've got our solitaire
code ready to use, before
3:08
we can get back to main activity, we'll
need to add in resources for our cards.
3:11
Luckily, I know where we can find some
excellent assets for our game and
3:16
not only do they look great but
they're also free.
3:20
They're from a game studio in
the Netherlands named Kenney and
3:23
they've got tons of great assets that
they share freely with the community.
3:25
If you're looking to make a game
sometime definitely check them out.
3:30
Anyway, follow the link in
the teacher's notes below
3:34
to get to the download page for
the board game pack.
3:37
Then we just need to download it,
Unzip it,
3:41
Then we can go into the PNG folder and
then the cards folder.
3:48
And there's the cards we need.
3:53
But before we add these to our project,
we need to make a small change.
3:55
Remember an Android resource files
aren't allowed to have capital letters.
4:00
So, we'll need to change these file
names to not have any capital letters.
4:06
To do this we just need to run
a simple script that can be found in
4:11
the teacher's notes below.
4:14
If you're on Windows,
copy the Windows version of the script and
4:16
then shift plus right click
inside the cards folder and
4:20
choose open command window here then
paste in the script and hit enter.
4:24
On the other hand, if you're on a Mac like
I am, then let's go to System Preferences
4:29
and then keyboard, then hit the shortcuts
tab and pick services on the left
4:37
and then check the box for
new terminal folder.
4:45
Now let's go back to our cards folder and
go up a level to the P and G folder.
4:51
Then let's right-click on the cards
folder and choose New Terminal at Folder.
4:58
Finally let's paste in the MAC
command from the teachers notes,
5:06
Hit enter and there we go.
5:13
If we go into our cards folder
now they're all lowercase.
5:17
Last but not least,
let's copy all of these cards and
5:21
paste them into our apps drawable folder.
5:24
We're not going to worry about
DPI differences for this app.
5:31
Great work.
5:36
We've got our code and
we've got our resources.
5:38
All that's left,
is putting it all together to make an app.
5:41
In the next video,
we'll finally start creating the UI.
