📝 Walkthrough

Walkthrough

Documentation updates across multiple SDK and ad-network guides adding Meta Install Referrer and Google Play Install Referrer guidance for Android device-level attribution. New sections describe setup, comparison, and decryption key notes; several insertions were duplicated within the same files.

Changes

Cohort / File(s)	Summary
Ad Network Docs ad-networks/meta-ads.mdx	Added "Getting Device-Level Data for Android Installs" describing Google Play Install Referrer API and Meta Install Referrer, setup/decryption key notes; content appears duplicated in two places.
Android SDK Docs sdk/android.mdx	Inserted "Adding Store Referrer Libraries" → "Meta Install Referrer" subsection (two insertions: near signing params and after init code) linking to Meta Install Referrer docs; only doc additions.
Expo SDK Docs sdk/expo.mdx	Added "Adding Store Referrer Libraries" with "Meta Install Referrer" guidance for Android attribution; duplicated insertion within file.
Flutter SDK Docs sdk/flutter.mdx	Added "Adding Store Referrer Libraries" / "Meta Install Referrer" content after Android config sections and near iOS config; documentation-only changes.
React Native SDK Docs sdk/react-native.mdx	Added "Adding Store Referrer Libraries" and "Meta Install Referrer" guidance (inserted adjacent to Expo support and Android backup sections); duplicated notices present.

Poem

🐰 I found a referrer in the night,

decrypts and keys all shining bright,
installs now trace with clearer cheer,
docs hop forward, bold and near,
a tiny rabbit celebrates the sight.

In @sdk/expo.mdx:
- Around line 78-84: Remove the duplicated standalone sentence "For improved
Android attribution tracking with Meta ads, see the [Meta Install Referrer
documentation](/features/meta-install-referrer)." and keep the reference only
within the "Adding Store Referrer Libraries" section (the "Meta Install
Referrer" subsection), so the documentation only references the Meta Install
Referrer doc once and the dedicated section remains as the discoverable
placement.

In @sdk/react-native.mdx:
- Around line 55-65: Remove the duplicate Meta Install Referrer note that
appears under the "Expo Support" subsection (the standalone sentence pointing to
the Meta Install Referrer documentation) and keep the dedicated "Adding Store
Referrer Libraries" section intact; specifically, delete the redundant line that
references the Meta Install Referrer documentation beneath the "Expo Support"
heading so the guidance is only present in the "Adding Store Referrer Libraries"
/ "Meta Install Referrer" section.

108-129: Remove duplicate Meta Install Referrer references.

Line 108 and lines 125-129 both reference the Meta Install Referrer documentation. The dedicated "Adding Store Referrer Libraries" section (lines 125-129) provides better structure and discoverability. Remove the standalone note at line 108 to eliminate redundancy.

sdk/android.mdx (2)

190-194: LGTM - Setup section well-placed.

The dedicated "Adding Store Referrer Libraries" section is appropriately positioned after SDK initialization parameters, providing clear setup guidance for developers.

---

244-244: LGTM - Contextual reminder is helpful.

The reminder about Meta Install Referrer within the "Getting Attribution Data" section provides helpful context at the point where developers retrieve attribution information. This complements the earlier setup section without being redundant.

ad-networks/meta-ads.mdx (1)

236-249: LGTM - Valuable comparison and guidance.

This section provides excellent context by comparing Google Play Install Referrer API with Meta Install Referrer, clearly explaining the advantages of the latter (broader data capture including impressions, multi-session support). The placement before troubleshooting is logical and helps users understand their attribution options.
