Introduction This document enumerates the requirements that must be met in order for devices to be compatible with Android 10.

7 The use of MUST , MUST NOT , REQUIRED , SHALL , SHALL NOT , SHOULD , SHOULD NOT , RECOMMENDED , MAY , and OPTIONAL is per the IETF standard defined in RFC2119 . As used in this document, a device implementer or implementer is a person or organization developing a hardware/software solution running Android 10. A device implementation or implementation" is the hardware/software solution so developed. To be considered compatible with Android 10, device implementations MUST meet the requirements presented in this Compatibility Definition , including any documents incorporated via reference. Where this Definition or the software tests described in section 10 is silent, ambiguous, or incomplete, it is the responsibility of the device implementer to ensure Compatibility with existing implementations.

8 For this reason, the Android Open Source Project is both the reference and preferred implementation of Android . Device implementers are STRONGLY RECOMMENDED to base their implementations to the greatest extent possible on the upstream source code available from the Android Open Source Project. While some components can hypothetically be replaced with alternate implementations, it is STRONGLY RECOMMENDED to not follow this practice, as passing the software tests will become substantially more difficult. It is the implementer's responsibility to ensure full behavioral Compatibility with the standard Android implementation, including and beyond the Compatibility Test Suite.

9 Finally, note that certain component substitutions and modifications are explicitly forbidden by this document. Many of the resources linked to in this document are derived directly or indirectly from the Android SDK and will be functionally identical to the information in that SDK's documentation. In any cases where this Compatibility Definition or the Compatibility Test Suite disagrees with the SDK. documentation, the SDK documentation is considered authoritative. Any technical details provided in the linked resources throughout this document are considered by inclusion to be part of this Compatibility Definition . Document Structure Requirements by Device Type Section 2 contains all of the requirements that apply to a specific device type.

10 Each subsection of Section 2 is dedicated to a specific device type. All the other requirements, that universally apply to any Android device implementations, are listed in the sections after Section 2 . These requirements are referenced as "Core Requirements" in this document. Requirement ID. Requirement ID is assigned for MUST requirements. The ID is assigned for MUST requirements only. STRONGLY RECOMMENDED requirements are marked as [SR] but ID is not assigned. The ID consists of : Device Type ID - Condition ID - Requirement ID ( C-0-1). Each ID is defined as below: Device Type ID (see more in 2. Device Types ). C: Core (Requirements that are applied to any Android device implementations).
