Walkthrough

This PR removes multiple configuration files, navigation infrastructure, state management, theme resources, and Firebase integration from the Mifos Android application. Deletions include the root navigation graph, AndroidClientViewModel, UI theme extensions, adaptive icon resources, theme definitions, and Google services configuration.

Changes

Cohort / File(s)	Summary
Configuration & Build Metadata mifosng-android/google-services.json, mifosng-android/lint-baseline.xml, mifosng-android/prod/release/output-metadata.json	Removed Google Firebase services configuration, lint baseline rules for AGP 8.5.0, and release artifact metadata including version info (2025.3.2-beta.0.4) and baseline profiles.
Navigation & State Management mifosng-android/src/main/java/com/mifos/mifosxdroid/navigation/RootNavGraph.kt, mifosng-android/src/main/java/com/mifos/mifosxdroid/AndroidClientViewModel.kt	Deleted root navigation setup (NavHost, sub-graphs for auth, server config, passcode, and home) and ViewModel managing UI state, theme preferences, authentication, app restart logic, and countdown toast utilities.
UI Utilities mifosng-android/src/main/java/com/mifos/mifosxdroid/utils/UiExtensions.kt	Removed extension property Configuration.isSystemInDarkTheme and extension function ComponentActivity.isSystemInDarkTheme(): Flow<Boolean> for system dark theme detection with configuration change listeners.
Launcher Icon Resources mifosng-android/src/main/res/mipmap-anydpi-v26/ic_launcher.xml, mifosng-android/src/main/res/mipmap-anydpi-v26/ic_launcher_round.xml	Removed adaptive icon resource definitions for API 26+ referencing launcher background and foreground drawables.
Theme Resources mifosng-android/src/main/res/values-night/themes.xml	Deleted night theme style declarations including NightAdjusted.Theme.Mifos and NightAdjusted.Theme.Splash with status bar and navigation bar light appearance settings.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

• Note: While deletions span multiple file types (config, navigation, theming, resources), the changes follow a consistent removal pattern with minimal logic density. Primary review focus should verify:
  • No remaining code references the removed ViewModel, navigation graph, or UI extension functions
  • Downstream dependencies on MainState sealed interface and AndroidClientViewModel have been migrated or refactored elsewhere

Poem

🐰 Files deleted, configs gone,
Navigation paths withdrawn,
Themes and icons fade away,
Cleaner code will save the day! ✨
Firebase bids its last goodbye,
As tech debts wave and say goodbye. 👋
