Add asserts for the S extension level in tests Guard these by checking the device SDK level first and adjusting the expectations accordingly. Note that the implementation is about to change, I'm just adding the assert logic first so the actual impl changes are clearer in the follow-up CL. Bug: 173188089 Test: derive_sdk_test Change-Id: Ic0fa1c06d2761c0390571900174810164b04e2cf
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:
SdkExtensions.getExtensionVersion
API support the new extensions.RollbackManagerServiceImpl#getExtensionVersions
to account for the new extension version.TODO(b/173188089): expand this section when derive_sdk is reimplemented
