service and ready for service requests.

available camera services from the System UI.

(cherry picked from commit 953c0fc975a4a4e50f6f81821c6d700cabf1fe18)
Native (C++) code format is required to be compatible with .clang-format file. Run
git clang-format --style=file --extension='h,cpp,cc' HEAD~
Note that clang-format is not desirable for Android java files. Therefore the command line above is limited to specific extensions.
