Feature Information

Performance is very important for AniTrend and we would like to monitoring UI dropped frames to monitor and optimise for various device configurations.

Solution Information

See: jankstats documentation for implementation and usage details

Additional Context

• Potentially use Timber.w to log dropped frames which will internally use the appropriate implementation of ISupportAnalytics based on the build flavour, which has already been implemented.

We haven't chosen an alternative to Firebase for our f-droid build yet, so currently all logging lives on the users device
