Information sent by the device in a "checkin" request.

Used in: AndroidCheckinRequest

• optional int64 last_checkin_msec = 2

  Miliseconds since the Unix epoch of the device's last successful checkin.

• optional string cell_operator = 6

  The current MCC+MNC of the mobile device's current cell.

• optional string sim_operator = 7

  The MCC+MNC of the SIM card (different from operator if the device is roaming, for instance).

• optional string roaming = 8

  The device's current roaming state (reported starting in eclair builds). Currently one of "{,not}mobile-{,not}roaming", if it is present at all.

• optional int32 user_number = 9

  For devices supporting multiple user profiles (which may be supported starting in jellybean), the ordinal number of the profile that is checking in. This is 0 for the primary profile (which can't be changed without wiping the device), and 1,2,3,... for additional profiles (which can be added and deleted freely).

• optional DeviceType type = 12

  Class of device. Indicates the type of build proto (IosBuildProto/ChromeBuildProto/AndroidBuildProto) That is included in this proto

• optional ChromeBuildProto chrome_build = 13

  For devices running MCS on Chrome, build-specific characteristics of the browser. There are no hardware aspects (except for ChromeOS). This will only be populated for Chrome builds/ChromeOS devices

Devices send this every few hours to tell us how they're doing.

• optional string imei = 1

  IMEI (used by GSM phones) is sent and stored as 15 decimal digits; the 15th is a check digit.

  IMEI, reported but not logged.

• optional string meid = 10

  MEID (used by CDMA phones) is sent and stored as 14 hexadecimal digits (no check digit).

  MEID, reported but not logged.

• repeated string mac_addr = 9

  MAC address (used by non-phone devices). 12 hexadecimal digits; no separators (eg "0016E6513AC2", not "00:16:E6:51:3A:C2").

  MAC address, reported but not logged.

• repeated string mac_addr_type = 19

  An array parallel to mac_addr, describing the type of interface. Currently accepted values: "wifi", "ethernet", "bluetooth". If not present, "wifi" is assumed.

• optional string serial_number = 16

  Serial number (a manufacturer-defined unique hardware identifier). Alphanumeric, case-insensitive.

• optional string esn = 17

  Older CDMA networks use an ESN (8 hex digits) instead of an MEID.

  ESN, reported but not logged

• optional int64 id = 2

  Android device ID, not logged

• optional int64 logging_id = 7

  Pseudonymous logging ID for Sawmill

• optional string digest = 3

  Digest of device provisioning, not logged.

• optional string locale = 6

  Current locale in standard (xx_XX) format

• required AndroidCheckinProto checkin = 4

• optional string desired_build = 5

  DEPRECATED, see AndroidCheckinProto.requested_group

• optional string market_checkin = 8

  Blob of data from the Market app to be passed to Market API server

• repeated string account_cookie = 11

  SID cookies of any google accounts stored on the phone. Not logged.

• optional string time_zone = 12

  Time zone. Not currently logged.

• optional fixed64 security_token = 13

  Security token used to validate the checkin request. Required for android IDs issued to Froyo+ devices, not for legacy IDs.

• optional int32 version = 14

  Version of checkin protocol. There are currently two versions: - version field missing: android IDs are assigned based on hardware identifiers. unsecured in the sense that you can "unregister" someone's phone by sending a registration request with their IMEI/MEID/MAC. - version=2: android IDs are assigned randomly. The device is sent a security token that must be included in all future checkins for that android id. - version=3: same as version 2, but the 'fragment' field is provided, and the device understands incremental updates to the gservices table (ie, only returning the keys whose values have changed.) (version=1 was skipped to avoid confusion with the "missing" version field that is effectively version 1.)

• repeated string ota_cert = 15

  OTA certs accepted by device (base-64 SHA-1 of cert files). Not logged.

• optional int32 fragment = 20

  A single CheckinTask on the device may lead to multiple checkin requests if there is too much log data to upload in a single request. For version 3 and up, this field will be filled in with the number of the request, starting with 0.

• optional string user_name = 21

  For devices supporting multiple users, the name of the current profile (they all check in independently, just as if they were multiple physical devices). This may not be set, even if the device is using multiuser. (checkin.user_number should be set to the ordinal of the user.)

• optional int32 user_serial_number = 22

  For devices supporting multiple user profiles, the serial number for the user checking in. Not logged. May not be set, even if the device supportes multiuser. checkin.user_number is the ordinal of the user (0, 1, 2, ...), which may be reused if users are deleted and re-created. user_serial_number is never reused (unless the device is wiped).

The response to the device.

• required bool stats_ok = 1

  Whether statistics were recorded properly.

• optional int64 time_msec = 3

  Time of day from server (Java epoch).

• optional string digest = 4

  Provisioning is sent if the request included an obsolete digest. For version <= 2, 'digest' contains the digest that should be sent back to the server on the next checkin, and 'setting' contains the entire gservices table (which replaces the entire current table on the device). for version >= 3, 'digest' will be absent. If 'settings_diff' is false, then 'setting' contains the entire table, as in version 2. If 'settings_diff' is true, then 'delete_setting' contains the keys to delete, and 'setting' contains only keys to be added or for which the value has changed. All other keys in the current table should be left untouched. If 'settings_diff' is absent, don't touch the existing gservices table.

• optional bool settings_diff = 9

• repeated string delete_setting = 10

• repeated GservicesSetting setting = 5

• optional bool market_ok = 6

  If Market got the market_checkin data OK.

• optional fixed64 android_id = 7

  From the request, or newly assigned

• optional fixed64 security_token = 8

  The associated security token

• optional string version_info = 11
