All Android OEM’s that opt to use Google Mobile Services (GMS) must adhere to a _________ and successfully pass ____________.

Android OEMs using Google Mobile Services (GMS) must adhere to the Compatibility Definition Document (CDD) and successfully pass the Compatibility Test Suite (CTS). The CDD outlines the requirements for Android devices to be compatible with the Android ecosystem, ensuring a consistent experience across different hardware. The CTS is a set of tests that verify a device's compliance with the CDD. Without meeting these two criteria, an OEM cannot ship devices with GMS applications like the Google Play Store. "Android Test Suite (ATS)" and "Android Device Test (ADT)" are not standard, official terms for the required compliance testing. "Enterprise Recommended Document (ERD)" is not a mandatory document for all GMS-enabled devices; it's a program for devices meeting specific enterprise-grade requirements.
