This identifier points to an automatically created resource overlay package specifically designed for a product. Its purpose is to customize a system image based on the specific product it will be installed on. For example, a device manufacturer might use this mechanism to change default settings, branding elements, or application configurations to align with the product’s target market or hardware capabilities.
Its significance lies in enabling product-specific customization without directly modifying the core Android system image. This approach simplifies maintenance and updates, as customizations are isolated within the overlay package. Historically, this method represents a refinement in Android’s approach to device-specific adaptations, shifting from direct system image alterations towards modular, overlay-based implementations. This improves stability and reduces the risk of conflicts during system updates.
