Observability into mobile native applications presents unique challenges, from capturing real user interactions to dealing with network constraints and battery efficiency. In this episode of OpenObservability Talks, we explore the special characteristics of client-side telemetry, and how OpenTelemetry helps generate mobile client telemetry for real user monitoring (RUM), enabling deeper insights into performance and user experience. 

We host Hanson Ho, Android architect at Embrace and an approver on the OpenTelemetry Android SDK. Hanson brings a wealth of experience from Twitter, Salesforce and SAP. He will share his expertise on instrumenting mobile apps, the evolution of OpenTelemetry for Android, and best practices for collecting and analyzing mobile telemetry. Tune in to learn how to bring OpenTelemetry-powered observability to your mobile applications!
