Merge "Add document for GSI specific packages" am: 0170eba510 am: 31f94b5321 am: af74d9fd19 Original change: https://android-review.googlesource.com/c/device/generic/common/+/2266746 Change-Id: I2b0f88d3a32153ca07274508a4606e8fdfef3e7d Signed-off-by: Automerger Merge Worker <android-build-automerger-merge-worker@system.gserviceaccount.com>
This document introduces special GSI settings for facilitating xTS-on-GSI with a single image.
Some devices access the private android framework resource by @*android: while overlaying their SystemUI setting status_bar_header_height_keyguard. However, referencing private framework resource IDs from RRO packages in the vendor partition crashes on these devices when GSI is used. This is because private framework resource don't have a stable ID, and these vendor RRO packages would be referencing to dangling resource references after GSI is used (b/245806899).
In order to prevent SystemUI crash, GSI adds a runtime resource overlay in the system_ext partition, which have higher overlay precedence than RROs on vendor partition, so the problematic vendor RROs would be overridden.
