Upgrade your Android applications to the new Splunk RUM agent.

The session replay feature has been redesigned and now supports mobile user sessions. This feature consists of two components:

  • The new sessionReplay module is an SDK that contains all of the logic for recording user sessions on browser and mobile applications. You can download this module from a Git repository and add calls to its methods to your application code to start and stop recordings, control the recording quality, and redact sensitive data. See Set up iOS session replay or Set up Android session replay.

  • The redesigned playback widget on the Splunk RUM user interface displays the data captured by the sessionReplay module. The playback widget simulates browser tabs, displays JavaScript errors and crashes on the session timeline, and allows you to skip inactive periods in the session.
