Android XML Views Standards

Priority: P1

Implementation Guidelines

ViewBinding

• Standard: Use ViewBinding for all XML layouts.
• Synthetics: kotlin-android-extensions is Dead. Remove it.
• KAPT: Avoid DataBinding unless strictly necessary (impacts build speed).

RecyclerView

• Adapter: Always inherit ListAdapter (wraps AsyncListDiffer).
• Updates: Provide a proper DiffUtil.ItemCallback. NEVER call notifyDataSetChanged().

Layouts

• ConstraintLayout: Use for complex flat hierarchies.
• Performance: Avoid deep nesting (LinearLayout inside LinearLayout).

Anti-Patterns

• No findViewById: Deprecated. Use ViewBinding for all XML layouts.
• No kotlin-android-extensions: Deprecated. Remove all import kotlinx.android.synthetic.*.
