📜 Description

Create the new sentry-android-navigation3 module and wire it into the build.

This keeps the first step of the stack focused on the module boundary itself: Gradle registration,
module layout, and Android library scaffolding, without introducing implementation code yet.

💡 Motivation and Context

Before we can add any Nav3 behavior, we need a clean module home for it. Splitting that setup out
first makes the rest of the stack easier to review and reason about.

addresses: JAVA-274

💚 How did you test it?

Built it + verified the config works correctly with the remaining PRs in this stack.

📝 Checklist

• I added GH Issue ID & Linear ID
• I added tests to verify the changes.
• No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled.
• I updated the docs if needed.
• I updated the wizard if needed.
• Review from the native team if needed.
• No breaking change or entry added to the changelog.
• No breaking change for hybrid SDKs or communicated to hybrid SDKs.
• Public API changes reviewed by another Mobile SDK team member or implemented according to the develop docs spec.

🔮 Next steps

Layer route modeling on top of the module scaffold.

LGTM! just some nits

Looking good! Not sure (yet) if it's covered by a follow up PR, but we probably need to add the module to the following too:

• .craft.yml
• AGENTS.md
• .aar config

  sentry-java/buildSrc/src/main/java/Config.kt

  Lines 95 to 102 in 113f678

  	object BuildScript {
  	val androidLibs = setOf(
  	"sentry-android-core",
  	"sentry-android-ndk",
  	"sentry-android-fragment",
  	"sentry-android-navigation",
  	"sentry-android-timber",
  	"sentry-compose-android",

Good callouts!

I'm leaving craft.yml out for now because don't want to publish until we actually release the feature. (Should've mentioned that in a comment – sorry! It's on my todo list for the release PR).

Updated AGENTS.md and the bug report template (and already added to .aar config) 👍
