How to Build Your First App for Android Automotive OS – Grape Up


Android Automotive OS is receiving a lot more recognition as automotive businesses are looking to deliver their customers with a much more customized encounter. Listed here we share our manual to building the very first app for AAOS.

Just before you start out, browse our initial article about AAOS and get to know our critique to be conscious of what to assume. Let’s try out making a uncomplicated Howdy Environment app for android automotive. To get an IDE, go to Android Studio Preview | Android Builders and get a canary develop:

AAOS Hello World: How to Build Your First App for Android Automotive OS

In the subsequent action, put together SDK, check and download the Automotive method image in SDK manager. You can get any from api32, Android 9, or Android 10, but I do not suggest the most recent 1 as it is really laggy and crashes a whole lot appropriate now. There are also Volvo and Polestar images.

For these you need to have to include links to SDK Update Internet sites:

Start out a new task, go to File> New Venture and opt for automotive with no activity

Android Automotive OS

A awesome and clean up venture need to be made, without the need of any classes: Go to make.gradle and incorporate the automobile application library into dependencies, refresh the task to make it get

AAOS Hello World

our new dependency:

implementation "androidx.automobile.application:application-automotive:1.2.-rc01"

Let’s publish some code, very first our monitor class. Identify it as you want and make it prolong Display course from android.motor vehicle.application package and make it employ expected approaches:

general public class GrapeAppScreen extends Display 

   community GrapeAppScreen(@NonNull CarContext carContext) 

   public Template onGetTemplate() 
       Row row = new Row.Builder()
.setTitle("Thats our Grape App!").build()

       return new PaneTemplate.Builder(
               new Pane.Builder()

That ought to make a basic screen with our icon and title, now produce a different course extending CarAppService from the same offer and as perfectly make it put into practice the needed approaches. From createHostValidator() approach return a static 1 that permits all hostnames for the intent of this tutorial and return model new session with our monitor in onCreateSession(), go CarContext employing Session course getCarContext() technique:

public course GrapeAppService extends CarAppService 

   community GrapeAppService() 

   public HostValidator createHostValidator() 
       return HostValidator.Allow_ALL_HOSTS_VALIDATOR

community Session onCreateSession() 
   return new Session() 
       general public Screen onCreateScreen(@Nullable Intent intent) 
           return new GrapeAppScreen(getCarContext())

Subsequent, shift to AndroidManifest and insert a variety of functions within the main manifest tag:

Inside the Application tag increase our support and exercise, never ignore minCarApiLevel as absence of this will toss an exception on app start:




Now we can upload our software to the product, confirm that you have an automotive emulator designed, use automotive configuration, and hit operate. The app is run in Google Automotive App Host, so if it is your initially application on this gadget, it may involve you to get to the enjoy retail outlet and get it.

That’s how it appears to be like:

The past detail, we’ll increase a navigation button that will pop a Toast. Modify onGetTemplate() in Monitor class, insert Motion and ActionStrip:

Motion action = new Motion.Builder()
               () -> CarToast.makeText(getCarContext(), "Hi!", CarToast.Size_Brief).clearly show())
       .setTitle("Say hi!")

ActionStrip actionStrip = new 

Increase it to PaneTemplate:

return new PaneTemplate.Builder(
       new Pane.Builder()
)       .setActionStrip(actionStrip)

That’s our HelloWorld application:

Now you have the HelloWorld instance application up and functioning applying Car or truck Application Library. It normally takes care of displaying and arranging everything on the monitor for us. The only obligation is to insert screens and actions we would like to have(and a bit of configuration). Check the Car application library to explore additional of what can be carried out with it, participate in all over with creating your app, and surely verify our website soon for a lot more AAOS application creation content material.
