Move CtsSdkExtensions into SdkExtension repository am: f0e73550a1 am: b67e5b4032 Original change: https://android-review.googlesource.com/c/platform/packages/modules/SdkExtensions/+/1508718 Change-Id: I9927193d5c02f0f7767d755a4afa4052362341e7
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)
.
