4:31That's going to take awhile so it's the perfect opportunity
4:34to take a break, make a cup of tea,
4:36and think about things like how to monetize your app.
4:39[VIDEO PLAYBACK]
4:40-What do you think we should do about monetization?
4:41Because I feel like in-app billing
4:42would be great for all the extra skills and defenses
4:45but subscription would be so consistent.
4:47-Maybe we could try A/B testing both of them.
4:49See which one turns out to be more effective.
4:51-That's true.
4:51That's a good idea.
4:53-Hey.
4:54Should we worry about performance this early?
4:55I mean if you're being chased by a zombie,
4:57it seems like we'd want to be responsive.
4:59Right?
4:59-Right.
5:00So, clearly, we can't use any eNoms in our app.
5:02-I don't know.
5:03Is that risking premature optimization?
5:05-Hey now, listen here, we've talked--
5:06-All right.
5:07[RECORD SCRATCHING]
5:08-Download's done.
5:09[MUSIC PLAYING]
5:11
5:17[END PLAYBACK]
5:18MALE SPEAKER: OK.
5:19The download is complete.
5:20So hit Finish and your installation is done.
5:23Now you're ready to start coding.
5:25We'll start by creating a new Hello World project
5:27that you can build from.
5:29Now, keep in mind that Android Studio is constantly
5:31being updated and improved.
5:33As a result, the process for your particular version
5:35may look a little different to what I'm showing on screen.
5:39Don't be alarmed.
5:40The options presented in the general flow
5:42should still be very similar.
5:44Start by choosing to start a new Android Studio project.
5:47Give it a name and enter a domain.
5:50These two will be used together to form your app's package
5:52name.
5:53Package names must be unique.
5:54So, ideally, you'll own a domain and you can use it here.
5:58Even if you don't, try and select
5:59something that's unlikely to collide with another developer.
6:03I happen to own a domain so I'll enter that here.
6:06I'm happy to use the default project location.
6:08So let's hit Next to continue.
6:12Now we can select the devices we plan to target with our app.
6:15Eventually we'll want to make our app
6:16available on all possible form factors.
6:19But for our first ever application,
6:21let's keep it simple and target only phones and tablets.
6:24Next we can choose the minimum SDK we plan to support.
6:27Selecting a min SDK lets you choose your app's level
6:30of backwards compatibility.
6:32A lower value will make your app available to a larger
6:34number of devices.
6:35But in turn, will require you to do more work
6:38to ensure compatibility with devices
6:40that may not support all the features added in newer Android
6:43releases.
6:44You can check to see what proportion of Android devices
6:47are running on each platform release
6:49by clicking this help me choose link.
6:52When we filmed this video in October of 2015,
6:55supporting back to Android 4.0 or Ice Cream Sandwich,
6:58let us reach around 90% of devices.
7:00
7:03Now you're prompted to select a new activity or user interface
7:06screen type to add to your project.
7:08To get started, we'll choose a blank activity.
7:11Give it a name and a title.
7:13The other files, layout, and menu resources
7:15will be automatically generated for you.
7:17And you can keep the default names.
7:20Then hit Finish.
7:22Read some tips and wait for your new project to be created.
7:25This may take a little while the very first time you run it.
7:27So here's one we prepared earlier.
7:31Your Hello World app is now ready to run.
7:34You can see it running on the emulator
7:35by hitting the green Run button like this
7:38and selecting the emulator.
7:39
7:42But it's much more fun to run it on a real Android device.
7:45
7:48Enable USB debugging by navigating to the Settings
7:51and going down to About Phone.
7:53Then scroll down and press the build number seven times.
7:56This will enable developer options.
7:58Navigate back.
7:59Select Developer options and enable US
8:01bugging from within there.
8:04If you're running Windows, you'll
8:05also need to download a driver for your phone.
8:07You can find drivers and installation instructions
8:10for them here on the Android developer site
8:12at developer.androi d.com/tools/extra/oem-usb.
8:17Now plug your phone into your computer and if prompted,
8:19choose to allow USB debugging.
8:21Hit the Run button in Android Studio but this time,
8:24select your real device.
8:26Congratulations.
8:27You are running your first app on a real phone.
8:30With that, you're ready to start building a real app.
8:33Unlike this example, you need to spend
8:35a lot of time working on a delightful, responsive, and
8:38intuitive user experience.
8:40Speaking of which, let's see how our start-up is getting on.
8:43[VIDEO PLAYBACK]
8:45-So I've got the app running but,
8:47how do I know if it's working?
8:49-It's not working.
8:51-Have you enabled real time location in the settings?
8:53-Wait, is that the brain icon
