To find out how users will access your app settings, visit [Sign-in, settings \\& search](/cars/design/automotive-os/apps/media/interaction-model/signin-settings-search).\n| **Note:** To implement a settings function in your app, you need to declare a Settings activity in your app's manifest file. For details, consult [Add a Settings activity](https://developer.android.com/training/cars/media/automotive-os#settings-activity).\n\nAs you design your settings flow, keep in mind the requirements and guidelines below.\n\n*** ** * ** ***\n\nLayout requirements\n-------------------\n\nCurrently, you need to design versions of your settings screens for both portrait and landscape layouts:\n\n- A portrait-mode layout for the screen size used in the Volvo Polestar 2 (1068 x 1425dp; 1152 x 153px)\n- A landscape-mode layout for the screen size used in Google's reference Automotive implementation (1075 x 806dp; 1024 x 768px)\n\nYou can use the emulator in Android Studio to see how your [layouts](/cars/design/automotive-os/design-system/layout) look in these two implementations. You can also consult Layout for reference information about how car makers' layouts are adapted to various screen sizes (keeping in mind that details such as margins and padding values may be changed by the car maker). \n[Test your app for Android Automotive OS\nHow to run the emulator in Android Studio](https://developer.android.com/training/cars/testing#test-automotive-os)\n\n*** ** * ** ***\n\nSettings example \\& guidelines\n------------------------------\n\nThe app bar in the media app template includes an option for a Settings control, which users can select to bring up an overlay with your app settings screen.\nA typical settings screen includes the types of elements shown here, in accordance with the guidelines that follow.\n\n*** ** * ** ***\n\nSettings guidelines\n-------------------\n\nIn addition to these guidelines, be sure to consult the general style guidelines in [Guidelines for custom screens](/cars/design/automotive-os/apps/media/guidelines-custom-screens).\n\n| Requirement level | Guidelines |\n|-------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| **SHOULD** | App developers should: - Keep settings simple and easy to navigate - Include only settings that are necessary for app use (such as account info, app preferences, and sign-in/sign-out) or relevant to listening to media in the car (for example, turning off explicit content) - Make all settings accessible from a single screen, if possible - Avoid use of dialogs beyond simple confirmation |\n\n**Rationale:**\n\n- **Design for cars:** Keep in-car settings to the minimum required for that environment, and make them easy to find and use."]]
