Stop Passing Class in Kotlin: Mastering Reified Type Parameters 🚀

 Master Reified Type Parameters to Write Cleaner, Type-Safe, and Idiomatic Code. If you’ve migrated from Java to Kotlin, you’ve likely felt the “Boilerplate Tax” — passing class types manually just to satisfy the runtime. val user = gson.fromJson(jsonString, User::class.java) In idiomatic Kotlin, we eliminate this using  Inline Functions  and  Reified Type Parameters . But for senior developers, the real question isn’t just  how  to use them, but  how  the compiler manipulates your bytecode to make it happen. 🔍 The Technical Root: JVM Type Erasure To understand Reified types, you must first understand what they defeat. On the JVM, generics are a compile-time safety net. At runtime, a  List<String>  and a  List<Int>  are identical—both are just a raw  List . Because the runtime “erases” the type  T , you’ve traditionally been forced to pass  Class<T>  as a manual "witness."  Reified ty...

Android Location Best Practices: The Definitive Guide to Fused Location & Battery Optimization

Image
 Why raw GPS is obsolete and how to implement battery-efficient, sensor-fused location updates in modern Android. Master modern Android location development. This definitive guide covers Fused Location Provider, background execution limits, battery optimization, callbackFlow architecture, and permission handling. In the early days of Android development, getting a device’s location felt like a gamble between precision and battery life. Developers manually toggled  GPS_PROVIDER  or  NETWORK_PROVIDER  via the old  LocationManager , often leading to "battery shaming" notifications and inconsistent user experiences. In the modern Android ecosystem, manual provider management is no longer just “legacy” — it is a liability. High-performance development requires a shift toward the  Fused Location Provider (FLP) . In a privacy-first, battery-conscious world, intelligent location architecture is a competitive advantage. 1. Why LocationManager is Obsolete (mostl...
