Description
Followed this guide to implement RTU KPI metric on our app.
https://community.amazondeveloper.com/t/how-to-implement-reportfullydrawn-marker-for-webview-apps/9267
Using this doc to test the KPI integration:
https://developer.amazon.com/docs/kepler-tv/ks-measure-app-kpis.html#measure-kpis-in-vs-code
App was installed on the device, and tried both debug and release builds.
- Testing from CLI - https://developer.amazon.com/docs/kepler-tv/ks-measure-app-kpis.html#measure-kpis-with-cli-commands
The suggested command is showing invalid:
perf doctor --app-name=in.startv.hotstar
perf <command> [options] [parameters]
: error: argument : invalid choice: 'doctor' (choose from 'activity-monitor', 'record', 'kpi-visualizer')
Then I tried : perf kpi-visualizer --app-name=in.startv.hotstar
This worked but gave an error after rebooting completes.
