* *****************************************************************************
* Below are all of the individual atoms that are logged by Android via statsd.
*
* RULES:
* - The field ids for each atom must start at 1, and count upwards by 1.
* Skipping field ids is not allowed.
* - These form an API, so renaming, renumbering or removing fields is
* not allowed between android releases. (This is not currently enforced,
* but there will be a tool to enforce this restriction).
* - The types must be built-in protocol buffer types, namely, no sub-messages
* are allowed (yet). The bytes type is also not allowed.
* - The CamelCase name of the message type should match the
* underscore_separated name as defined in Atom.
* - If an atom represents work that can be attributed to an app, there can
* be exactly one AttributionChain field. It must be field number 1.
* - A field that is a uid should be a string field, tagged with the [xxx]
* annotation. The generated code on android will be represented by UIDs,
* and those UIDs will be translated in xxx to those strings.
*
* CONVENTIONS:
* - Events are past tense. e.g. ScreenStateChanged, not ScreenStateChange.
* - If there is a UID, it goes first. Think in an object-oriented fashion.
