Summary

  • Adds androidNetworkingOptions to Auth0Options, exposing Auth0.Android's DefaultClient.Builder (connect/read/write/call timeouts, default headers, debug-only request logging) for every native request the SDK makes (web auth, credential renewal, MFA, passkeys, My Account API).
  • Android only — accepted and ignored on iOS for API compatibility. enableLogging is intentionally debug-only since Auth0.Android logs full request/response bodies (including tokens) at that level.
  • Threaded through the core config signature (so the option triggers native re-init when changed), the TurboModule spec, the native bridge manager, and the native adapter.

Test plan

  • yarn typecheck — clean
  • yarn test — 36/36 suites, 712/712 tests pass (new coverage in configSignature.spec.ts, NativeAuth0Client.spec.ts, NativeBridgeManager.spec.ts)
  • yarn lint — clean on all changed files
  • Android unit tests (./gradlew :react-native-auth0:testDebugUnitTest) — new A0Auth0ModuleNetworkingOptionsTest (2/2) verifies readTimeout and defaultHeaders are genuinely applied to the built DefaultClient against a real MockWebServer
  • EXAMPLES.md updated with a new "Android Networking Configuration" section

Review Change Stack

📝 Walkthrough

Walkthrough

The change adds Android networking options for timeouts, default headers, and debug logging. It propagates these options through native initialization, applies them to DefaultClient, updates configuration signatures, preserves iOS behavior, and adds tests and documentation.

Changes

Android networking options

Layer / File(s) Summary
Networking configuration contract
src/types/common.ts, src/specs/NativeA0Auth0.ts, src/core/utils/configSignature.ts, src/platforms/native/bridge/*
Adds the public NetworkingOptions interface and optional initialization parameter. Configuration signatures include networking options. DPoPHeadersParameters replaces the former name while retaining a deprecated alias.
Native initialization propagation
src/platforms/native/adapters/*, src/platforms/native/bridge/*, ios/A0Auth0.mm
Forwards networking options through the native bridge and ignores them on iOS. Tests cover supplied and omitted arguments across initialization and re-synchronization paths.
Android client configuration and validation
android/src/main/java/com/auth0/react/A0Auth0Module.kt, android/src/test/java/com/auth0/react/A0Auth0ModuleNetworkingOptionsTest.kt, android/build.gradle, .github/workflows/main.yml, EXAMPLES.md
Builds a configured DefaultClient with timeout, header, and debug-only logging settings. Tests validate timeout, headers, logging suppression, and default-client restoration. Documentation covers networking options and error handling examples.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 83cb0

This PR exposes Android networking controls across native authentication requests. It is not merge-ready yet because logging may expose tokens in release builds, reused clients may retain stale networking settings, and invalid timeout values may prevent client construction.

explicitly reset to DefaultClient() when options are absent, while retaining

the client is restored to the default.

Nice change, and good call verifying the timeouts against a real MockWebServer rather than just asserting the builder was called. Couple of things inline, plus I've replied on the two existing threads.

Comment thread src/platforms/native/bridge/NativeBridge.ts
Adds `androidNetworkingOptions` to `Auth0Options`, letting apps tune the
OkHttp-based `DefaultClient` (connect/read/write/call timeouts, default
headers, and debug logging) that Auth0.Android uses for every native
request. Android only; accepted and ignored on iOS for API compatibility.

Ref: SDK-10614
…ild.gradle

Verified the new A0Auth0ModuleNetworkingOptionsTest suite passes identically
with or without this option — nothing in buildNetworkingClient()'s path
touches an unstubbed Android framework API, so the fallback is dead config.
…ng config across clients

DefaultClient.Builder.enableLogging logs full request/response bodies, including
tokens, at the token endpoint. Forwarding androidNetworkingOptions.enableLogging
unconditionally meant a release build could log tokens if a consumer set it to
true. It's now only honored when the host app is debuggable.

Auth0.getInstance(clientId, domain) returns a shared singleton, so a client that
omits androidNetworkingOptions could silently inherit another client's timeouts
and defaultHeaders (via re-init or a sibling client with the same clientId).
networkingClient is now always set explicitly, defaulting to DefaultClient()
when no options are given.
…hConfiguration

auth0!! could theoretically crash if a caller raced this method against a
concurrent reset. Capturing Auth0.getInstance()'s result in a local val
before assigning the auth0 field lets Kotlin's type system guarantee
non-null for the rest of this method without asserting it.
Every other platform-specific option on Auth0Options (maxRetries,
credentialsManagerStorageKey) documents its platform restriction via
@remarks rather than baking the platform name into the identifier.
androidNetworkingOptions was the one exception. Since v6 hasn't shipped
yet, rename it now while it's free, ahead of adding iOS networking
config under its own umbrella later.

Add coverage for every networkingOptions field. getConfigSignature includes networkingOptions and sorts its keys, so changes trigger native reinitialization. The tests cover only connectTimeout and key-order stability. Add tests for each timeout field, defaultHeaders, and enableLogging.
