Suggestions from the telephony or location origin. Stops if the primaryĪs shown in Figure 1, the time_zone_detector services receives time zone Permanent failure, or times out during initialization. Secondary LTZP Runs if the primary LTZP reports that the time zone is uncertain, reports a Primary and a secondary LTZP as defined here: Primary LTZP Runs at all times when the user has allowed the location time zone detectionįeature to run. The AOSP location time zone detection implementation allows up to two LTZPs, a This also depends on the implementations of the LTZPs One is needed) when the current user changes to avoid sharing locationĪs a result of these choices, it usually takes a few seconds after switching theĬurrent origin to location, or after switching the current user, before the time Obtaining the device's location is privacy sensitive.Īlso, the location_time_zone_manager service makes an uncertain suggestion (if.

Location settings are user scoped and Android must respect the current.Normal telephony operations, location can be actively requested fromĪndroid location providers and could consume additional power. Unlike telephony signals that are received passively as part of.
Reasons for this behavior include the following: The device's location unless they are explicitly required to. Means that the location time zone detection system doesn't ask LTZPs to track When location time zone detection isn't needed, the LTZPs aren't started. It's responsible for managing the lifecycle of one or two plug-ins called The location_time_zone_manager service doesn't contain any time zone detection Location_time_zone_manager service runs in the system server process. Suggestions for the location origin of time_zone_detector. The location_time_zone_manager service is responsible for generating Time zone based on suggestions it receives from detection origins. The time_zone_detector service determines when to change the device's current LTZP implementations can use time zone map data heldĮntirely on the Android device, leverage servers, or use a hybrid
Location time zone detection is an alternative mechanism to telephony time zoneįeature doesn't require telephony, this feature can be supported on devices of Or higher, is an optional automatic time zone detection feature that allowsĭevices to use their location and time zone map data to determine the time zone.
