Mobile runtime environments are hostile! Networks come and go, batteries run out of juice, and connections disappear. The flow of data becomes unreliable. Observability solutions on mobile devices need to take these perils into consideration.

OpenTelemetry Android now contains an exciting feature that helps to make the delivery of observability data more robust. This session will provide an overview of the technical challenges imposed by the mobile runtime and the resulting design considerations. You will explore the implementation of the Android disk-buffering library and how it can be used to temporarily store OpenTelemetry data on the device for eventual egress. Lastly, you will learn how to wire up and configure disk buffering in a real Android application.
