| ## 1.1 Document Structure |
| |
| ### 1.1.1\. Requirements by Device Type |
| |
| [Section 2](#2_device_types) contains all of the requirements that apply to a |
| specific device type. Each subsection of [Section 2](#2_device_types) 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](#2_device_types). |
| These requirements are referenced as "Core Requirements" in this document. |
| |
| ### 1.1.2\. 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 |
| (e.g. C-0-1). |
| |
| Each ID is defined as below: |
| |
| * Device Type ID (see more in [2. Device Types](#2_device_types)) |
| * C: Core (Requirements that are applied to any Android device implementations) |
| * H: Android Handheld device |
| * T: Android Television device |
| * A: Android Automotive implementation |
| * W: Android Watch implementation |
| * Tab: Android Tablet implementation |
| * Condition ID |
| * When the requirement is unconditional, this ID is set as 0. |
| * When the requirement is conditional, 1 is assigned for the 1st |
| condition and the number increments by 1 within the same section and |
| the same device type. |
| * Requirement ID |
| * This ID starts from 1 and increments by 1 within the same section and |
| the same condition. |
| |
| ### 1.1.3\. Requirement ID in Section 2 |
| |
| The Requirement ID in [Section 2](#2_device_types) starts with the corresponding |
| section ID that is followed by the Requirement ID described above. |
| |
| * The ID in [Section 2](#2_device_types) consists of : |
| Section ID / Device Type ID - Condition ID - Requirement ID (e.g. 7.4.3/A-0-1). |
