Since the O SDK roll, running "build/android/play_services/update.py sdk" (which in turn runs "third_party/android_tools/sdk/tools/android update sdk") now prints:

"""
*************************************************************************
The "android" command is deprecated.
For manual SDK, AVD, and project management, please use Android Studio.
For command-line tools, use tools/bin/sdkmanager and tools/bin/avdmanager
*************************************************************************
"android" SDK commands can be translated to sdkmanager commands on a best-effort basis.
Continue? (This prompt can be suppressed with the --use-sdk-wrapper command-line argument
or by setting the USE_SDK_WRAPPER environment variable) [y/N]:
