How advertising SDKs work

An advertising SDK connects an application to request, rendering and measurement interfaces. Receiving a response does not automatically mean an impression occurred.
Separate transport, renderer and measurement
A request component exchanges data with an advertising service. A renderer displays the response in the application. Measurement records documented events from that renderer. An SDK may provide some or all of those pieces; the package name alone does not tell you which.
Before installation, identify the package version, supported runtime, renderer requirements, credentials, consent handling and no-fill behavior. Treat these as separate acceptance items.
Write a placement state model
A simple model can use idle, requesting, empty, ready, displaying, failed and disposed states. These are suggested application states, not ADX method names. The model makes it possible to test what happens when the user navigates away before a request completes.
In an empty state, keep the application usable. In a disposed state, ignore stale callbacks and remove listeners. If the placement reserves space, choose its empty-state behavior deliberately; collapsing an already visible slot can move surrounding content.
| Scenario | Expected application behavior |
|---|---|
| No eligible ad | Show an intentional empty state without a false impression |
| Request times out | Bound the wait and preserve app interaction |
| Component unmounts | Clean up resources and ignore stale work |
| Renderer fails | Record a renderer error separately from request success |
| Repeated callback | Avoid reporting the same event twice |
Put permission checks before data transfer
A privacy interface should influence what is sent and when the request starts. The exact requirements depend on the integration and applicable policies; do not assume that disabling personalized ads removes every consent obligation. Obtain the required product and privacy review.
Keep debugging data minimal. Logging an entire request or user URL can expose information unrelated to resolving the integration fault. Prefer bounded event types and correlation identifiers where the contract permits them.
Test a real runtime, not just a successful import
A useful acceptance record includes a clean installation, no-fill path, supported rendering, event ordering, cleanup and privacy behavior on the target platform. A compiler result cannot substitute for every device test.
Use ADX’s documented local no-fill quickstart to explore the lifecycle without contacting production auctions. This guide introduces the boundaries; it does not promote an experimental runtime to general availability.
