Version 6.0.0
We are very excited to announce version 6.0.0 of the Android tracker.
Enhancements
Screen time and engagement metrics
The Android tracker can now track screen engagement information, including the screen time and metrics for the amount of content viewed on the screen! Visit this demo to see it in action! This works nicely together with the Snowplow Unified dbt package 0.2.0.
- Add screen engagement tracking of time spent and list items scrolled on a screen (#654)
- Enable lifecycle autotracking by default (#651)
Local event store automatic cleanup
The trackers can now automatically remove old events from the event store in situations when requests are blocked due to ad blockers or in case of longer offline usage.
- Add configurable limit for the maximum age and number of events in the event store and remove old events before sending (#660)
Tackling duplicate events
We have improved the trackers to avoid sending duplicate events to the Collector by making requests serially and adjusting request timeouts.
- Change default emit timeout from 5 seconds to 30 seconds (#658)
- Make network requests serially in network connection (#646)
Batching improvements
The event batching algorithm has been improved to make it possible to make requests to the collector after a certain number of events accumulate in the event store (defaults to 1, but configurable to 10 or 25).
- Change default buffer option to single (#649)
- Flush events only when the buffer is full (#648), thanks to @danigutierrezayuso
Cross-navigation tracking
There is a new API to decorate outgoing links to other Web or mobile apps with user and session information.
- Add API to decorate link with user/session info (#639)
Set custom values in the platform context entity
Provide callbacks for any of the platform context entity properties.
- Add an option to override platform context properties (#667)

- Fix demo crash when using R8 full mode (#652)

Under the hood
- Update copyright notices (#669)
- Tidy AbstractEvent internal properties (#666)

- Remove optional types in event store interface (#661)
- Set default thread count in Executor to match the default thread pool size in the Emitter (#659)

- Update Emitter constructor to accept namespace and event store and make them immutable (#659)
