Summary

Rewrites the contact creation screen (ACTION_INSERT) from legacy Java ContactEditorFragment to Kotlin + Jetpack Compose with Material 3 Expressive theming. The new screen provides full field-type parity with the original editor while following modern Android architecture patterns (MVI, Hilt, Coil, coroutines).

Tech stack: Kotlin, Jetpack Compose (BOM 2026.03.01), Material 3 + MotionScheme.expressive(), Hilt DI, Coil 3 for photo loading, Robolectric + Compose UI Test for testing.

Architecture

  • State-down, Events-up MVIContactCreationEditorScreen(uiState, accounts, onAction) with sealed ContactCreationAction / ContactCreationEffect
  • @HiltViewModel with SavedStateHandle for process-death persistence, Channel<Effect> for one-shot side effects
  • RawContactDeltaMapper bridges Compose UI state → legacy RawContactDelta / ValuesDelta for ContactSaveService
  • Column + verticalScroll (not LazyColumn) — form has ~25 fixed composables; Column avoids lazy-composition edge cases with AnimatedVisibility, IME focus, and SavedStateHandle
  • No ContactFieldsDelegate — ViewModel handles all field CRUD directly via copy(), keeping the architecture simpler

Key Decisions

Decision Rationale
Column over LazyColumn Form is bounded (~25 items), AnimatedVisibility works naturally, no recycling needed
TopAppBar (not LargeTopAppBar) Contact creation is a quick-entry form, collapsing title adds no value
Spring-based animations (DampingRatioLowBouncy + StiffnessMediumLow) M3 Expressive convention, consistent across all animated sections
AnimatedVisibility per chip in FlowRow with expandHorizontally/shrinkHorizontally Smooth reflow when chips are removed; animateContentSize on parent handles height
isReduceMotionEnabled() gating on all animations Accessibility — EnterTransition.None / ExitTransition.None / snap() when reduce motion enabled
Intent extras limited to NAME, PHONE, EMAIL GrapheneOS security — Insert.DATA (arbitrary ContentValues) explicitly rejected, all extras sanitized with max-length caps
Photo temp files in getCacheDir()/contact_photos/ Cleaned up in ViewModel.onCleared(), no PII leak on discard
Account selector as ModalBottomSheet (not chip) Cleaner UX for multi-account selection, proper radio-button semantics

Field Types (13 — full parity)

StructuredName, Phone, Email, StructuredPostal (Address), Organization, Nickname, SIP, IM, Website, Event, Relation, Note, Groups — each with type selector, custom label support, and add/remove.

Test Coverage

184 tests total across 15 test files:

Category Files Tests Framework
Mapper (all 13 field types) 1 ~90 JUnit (pure)
ViewModel (actions, effects, process death) 1 ~35 Robolectric + Turbine
Integration (VM + real mapper → delta verification) 1 9 Robolectric
Screen (rendering, actions, discard dialog, chips) 1 18 Compose UI Test
E2E flows (basic save, all fields, cancel, prefill, zero-account) 1 5 Compose UI Test
Component sections (Phone, Email, Address, Name, Org, Group, CustomLabel, FieldType) 8 ~42 Compose UI Test
Shared (TestFactory) 2
  • Zero onNodeWithText — all tests use testTag() with stable IDs from TestTags.kt
  • Lambda capture pattern for action assertions (onAction = { capturedActions.add(it) }) — no MockK in UI tests

What's Not In Scope

This PR covers contact creation only (ACTION_INSERT). The following are intentionally excluded:

  • Edit existing contacts (ACTION_EDIT)
  • Contact joining/linking/splitting/deletion
  • User profile editing
  • Aggregation suggestions

…r spacing

Major visual overhaul following M3 form guidelines + Google Contacts patterns.

Layout:
- Flat TopAppBar with Close (X) + "Save" text (was LargeTopAppBar + back + check)
- Column(verticalScroll) + imePadding (was LazyColumn)
- 120dp photo circle with surfaceContainerLow strip (was 96dp plain)
- SectionHeader (titleSmall, primary) before every field group
- HorizontalDivider between photo/account/content areas
- 24dp section spacing, 8dp field spacing (was 0dp)

Components:
- FieldRow: 40dp icon column, first-field-only icon, CenterVertically
- SectionHeader: titleSmall, primary color, 56dp start padding
- AddFieldButton: 56dp start, primary, Add icon + labelLarge

Sections:
- All sections converted from LazyListScope to @composable
- Nickname/Note/SIP wrapped in FieldRow with proper icons
- AOSP field order: Name→Phone→Email→Address→(More: Nickname→Org→SIP→IM→Website→Event→Relation→Note)→Groups
- ~296 LOC dead LazyListScope code removed

Review fixes: all P1/P2/P3 addressed, second review 14/14 pass.

R8 optimization could null-out the captured `type` variable from
forEach lambda in DropdownMenuItem onClick/text closures. Switch to
indexed for-loop with explicit types[i] access to avoid closure capture issues.

Fixes: FATAL EXCEPTION PhoneFieldRow$lambda$4$0$0 parameter it null

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
…n non-composable scope

Root cause: PhoneType.label() used stringResource() (@composable) but was
called inside List.map{} (non-composable lambda). The Compose compiler
didn't error at compile time, but at runtime the composable context was
missing, causing the receiver to be null.

Fix: Change label() from @composable to plain function taking Context
parameter. Pre-compute labels via context.getString() instead of
stringResource(). Also change FieldTypeSelector API from @composable
typeLabel lambda to pre-computed labels List<String>.

Note: stale SavedStateHandle data from previous builds can also cause
this crash — clear app data after schema-changing updates.

…e chips, tappable text buttons

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Remove section icons, headers; tighten margins (8dp same-type, 16dp between types)
- Replace circle remove buttons with text-based Add/Remove row pattern
- Fix FieldTypeSelector NPE: dispatch by index to avoid Popup composition null
- Add "Add more info" tonal buttons in 2-column grid with vertical spacing
- Implement account selector: footer "Saving to..." becomes tappable when >1 account,
  opens ModalBottomSheet with account list, validates selection against writable accounts
- Fix save callback: implement ContactSaveService.Listener for proper save→finish flow
- Delete unused AccountChip, remove LaunchAccountPicker effect

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Remove save button pulse animation (Animatable, LaunchedEffect,
graphicsLayer). Rewrite AddMoreInfoSection chip grid: replace buildList
+ MutableTransitionState with explicit AnimatedVisibility per chip,
expandHorizontally/shrinkHorizontally + fadeIn/fadeOut exit/enter
transitions with DampingRatioLowBouncy springs. Extract hardcoded
strings to resources. Gate animateContentSize on reduceMotion. Remove
outer AnimatedVisibility wrapper to avoid double animation on last chip.

…thods

- AddMoreInfoSection: extract AnimatedChipSlot, ChipButton, spring builders
- EmailSection/PhoneSection: extract type selector into helper composable
- OtherFieldsBottomSheet: data-driven list of entries instead of 6 branches
- PhotoSection: extract CameraBadge composable
- ContactCreationViewModel.onAction: split into handleSelectAccount +
  handleSectionToggleOrFieldUpdate to reduce cyclomatic complexity

Also: AddressSection gets animateContentSize + AnimatedVisibility for
consistency with Phone/Email sections.
