This guide is specifically for Android developers who:

The Mental Model:
Cold Start Deep Link Flow: ┌──────────────┐ │ Dashboard │ ← startDestination…
Really useful breakdown! Deep links often get treated as an afterthought, but they’re critical for modular navigation and cross-app integrations. I’ve found that combining them with navigation graph deep link support makes dynamic feature flows much…
