🚀 Brainwallet Android — Release Notes

v4.9.0

✨ New Features

📋 Copy Transaction Details to Clipboard

Transaction details can now be copied directly to the clipboard from the transaction detail view. A new BRClipboardManager.putDetailsClipboard() method handles the copy action with full analytics tracking, making it easy to share or reference transaction information outside the app.

📊 Analytics Tracking for Key Interactions

Firebase analytics events are now fired for core user interactions — fiat/LTC toggle, balance visibility toggle, and transaction detail copy — giving the team better insight into how users engage with the wallet's main screens.

🎨 UI / Design System

🧱 Unified bentoSurface Design System

A new bentoSurface() modifier in BentoModifiers.kt consolidates gradient and border styling across the entire bento UI. Previously hardcoded values like 1.dp borders are now driven by shared constants (bentoBorderWidth, bentoCornerRadius, bentoCornerRadius, bentoSpacer, transactionActionHt, transactionDetailHt), making the visual system consistent and easy to maintain going forward.

🃏 Bento Section Refactors

• GameHub — migrated from Card to Box with bentoSurface(), with a clickable modifier added
• Favourites — refactored to bentoSurface() with improved Spacer layout
• LTC Picker — label repositioned to top, spacing and item heights adjusted
• Transactions — TransactionFilter, TransactionsBentoScreen, ConfirmationStatus, CopyTransactionWidget, ExportTransactionsWidget, NoTxRow, TransactionDetail, TransactionFilterWidget, TransactionRow all updated to unified styling
• Tutorials & Bottom Nav Bar — updated to use unified theme system

v4.8.3

✨ New UI — Favourites & Tutorials Bento Sections

PR #191 The main screen now features two new purpose-built bento panels replacing the generic placeholder container. The Favourites panel displays a set of coloured circular indicators using the app's design theme colours (affirm, info, warn, error) with full dark/light mode support. The Tutorials panel shows a "Coming Soon" placeholder consistent with the broader bento design language. The old HomeBentoContainer has been removed. String resources for both sections have been translated across 19 locales including Arabic, Chinese (Traditional & Simplified), French, German, Farsi, Hindi, Indonesian, Italian, Japanese, Korean, Polish, Punjabi, Brazilian Portuguese, Russian, Spanish, Swedish, Turkish, and Ukrainian.

🔧 Send Screen Overhaul & Financial Precision

PR #182 The send transaction flow has been fully redesigned as a multi-step paged screen (Pre-send → Confirm → Authenticate). All monetary values have been migrated from Float to BigDecimal with explicit rounding modes, eliminating floating-point precision issues in fiat/LTC conversions. Transaction fees are now calculated dynamically using getFeePerKb() rather than a static default. The pre-send composable has been broken into focused sub-components (PreSendAddressRow, PreSendAmountRow, PreSendMemoRow), and passcode UI components have been extracted into a dedicated package. QR code scanning is now wired into the send flow via an EventBus event. A BWSender class handles transaction preparation with proper error handling and activity context management.

🧪 Test Coverage Expanded to 309 Tests

PR #182

Unit test coverage has been significantly expanded alongside the send screen work, bringing the total suite to 309 tests. New test classes include AppModuleTest, SendStateTest, and BrainwalletAppTest, covering the Koin DI module wiring, send state logic, and core app initialisation paths.
