Fix SdkExtensions e2e test on R - Introduce use of isAtLeastS() to change expectations based on the platform version of the device running the test. In order to re-use the existing impl of isAtLeastS(), this needs to be routed into the test app and communicated back. Because it's somewhat costly/slow, we cache the value. - Add two more "apps-with-reqs", and rename the existing ones. We now have apps with R-ext requirements and apps with R+S-ext requirements. - Refactor the asserts around versions a little bit to make it easier to reuse logic around isAtLeastS() etc. Test: atest --test-mapping packages/modules/SdkExtensions Change-Id: I88311631466a341169efa055731cb22d3eea0e58
SdkExtensions is a module that decides the extension SDK level of the device, and provides APIs for applications to query the extension SDK level.
The module is packaged in an apex, com.android.sdkext
, and has two components:
bin/derive_sdk
: Native binary that runs early in the device boot process and reads metadata of other modules, to set system properties relating to the extension SDK (for instance build.version.extensions.r
).javalib/framework-sdkextension.jar
: This is a jar on the bootclasspath that exposes APIs to applications to query the extension SDK level.derive_sdk
is a program that reads metadata stored in other apex modules, in the form of binary protobuf files in subpath etc/sdkinfo.binarypb
inside each apex. The structure of this protobuf can be seen here. The exact steps for converting a set of metadata files to actual extension versions is likely to change over time, and should not be depended upon.
The module exposes a java class SdkExtensions
in the package android.os.ext
. The method getExtensionVersion(int)
can be used to read the version of a particular sdk extension, e.g. getExtensionVersion(Build.VERSION_CODES.R)
.
For every new Android SDK level a new extension version should be defined. These are the steps necessary to do that:
derive_sdk.cpp
by:GetSdkLevel
with the new enum setderive_sdk_test.cpp
verifying the new extensions worksSdkExtensions.getExtensionVersion
API support the new extensions.RollbackManagerServiceImpl#getExtensionVersions
to account for the new extension version.
