# Partner roles for apps

<br />

Multiple partners contribute to the app experience in Android for Cars: app
developers, Google, and (for AAOS-based vehicles) vehicle OEMs.

The design role that each partner plays in creating the app experience depends
partly on the type of app. Apps created with the Android for Cars App Library
templates have a different partnership model than those with a more fixed UI
(such as media apps) or those meant for parked and passenger use cases (such as
video apps).

For details about some of these partnership models, see the resources linked
below.
