PostHog integration for Android

This skill helps you add PostHog analytics to Android applications.

Workflow

Follow these steps in order to complete the integration:

basic-integration-1.0-begin.md - PostHog Setup - Begin ← Start here
basic-integration-1.1-edit.md - PostHog Setup - Edit
basic-integration-1.2-revise.md - PostHog Setup - Revise
basic-integration-1.3-conclude.md - PostHog Setup - Conclusion

Reference files

references/EXAMPLE.md - Android example project code
references/android.md - Android - docs
references/identify-users.md - Identify users - docs
references/basic-integration-1.0-begin.md - PostHog setup - begin

The example project shows the target implementation pattern. Consult the documentation for API details.

Key principles

Environment variables: Always use environment variables for PostHog keys. Never hardcode them.
Minimal changes: Add PostHog code alongside existing integrations. Don't replace or restructure existing code.
Match the example: Your implementation should follow the example project's patterns as closely as possible.

Framework guidelines

Adapt dependency configuration to the appropriate build.gradle(.kts) file according to the project gradle version
Call PostHogAndroid.setup() only once in the Application class's onCreate() method, so it's initialized as early as possible and only once.
Initialize PostHog in the Application class's onCreate() method
Ensure every activity has a android:label to accurately track screen views.

Identifying users

Identify users during login and signup events. Refer to the example code and documentation for the correct identify pattern for this framework. If both frontend and backend code exist, pass the client-side session and distinct ID using X-POSTHOG-DISTINCT-ID and X-POSTHOG-SESSION-ID headers to maintain correlation.

Error tracking

Add PostHog error tracking to relevant files, particularly around critical user flows and API boundaries.
