Use ConnectivityManager and NetworkCapabilities as signals, not promises, and design Android networking around validated state, retries, and real request outcomes.
How to Handle Partial Success in Android ViewModels
A practical pattern for Android mutations that succeed before a follow-up refresh fails, without lying to the user or turning Compose callbacks into orchestration code.
Google Sheets as an Android Backend: A Practical Architecture
Use Google Sheets as a lightweight backend for an internal Android app without turning spreadsheet access, row updates, and credentials into production liabilities.

Kotlin val vs var in Android: Write State That Is Easier to Reason About
A practical guide to choosing val or var, designing function boundaries, and keeping Android state ownership explicit instead of spreading mutation across the UI.
How to Get the Date 30 Days Ago in Kotlin for Android
