Build-Time Auto-Instrumentation in Android
Talkat Observability Day North America 2024 · on Tuesday, 2024-11-12· at 14:40· Salt Palace | Level 2 | 255 B·
summary
Shows how OpenTelemetry build-time weaving uses the Byte Buddy Gradle plugin to inject instrumentation into Android APKs (demo adds one build line and a dependency) and wires four interceptors into OkHttp’s constructor so client traces link to a Jaeger backend. Build-time bytecode weaving operates on dex files and reliably produces linked client+server traces in the demo. Caveats: SDK initialization still requires manual setup, AGP compatibility gaps exist, and Compose / withSpan support is incomplete.
