Pull request overview

This pull request has a significant mismatch between its title/description and actual content. While titled "#issue167 Add Multisig EIP-41/EIP-11 Support Across Platforms" with an extensive description of multisig wallet features, the actual changes are predominantly infrastructure improvements and bug fixes with only foundational database schema additions for multisig (no implementation).

Actual Key Changes:

Gradle upgrade from 7.4 to 8.11.1 for Java 21/24 compatibility
Windows desktop JVM launch configuration fixes
F-Droid distribution preparation with reproducible builds
ErgoAuth address generation feature implementation
UI/UX improvements (storage rent warnings, device security warnings, token categorization)
Database schema additions for future multisig support (tables only, no logic)

PR_SUMMARY.md

+# PR Summary
+
+## Title
+**Fix critical issues: dependency, JVM launch, Java 21 support, F-Droid prep, and add ErgoAuth address generation**
+
+## Quick Summary
+This PR fixes four critical bugs and adds one major feature:
+1. ✅ **Fixed**: Build failure due to unavailable dependency
+2. ✅ **Fixed**: Windows desktop app failing to launch (CRITICAL)
+3. ✅ **Fixed**: Build failure on Java 21/24 with Gradle 7.4 (CRITICAL)
+4. ✅ **Added**: ErgoAuth address generation feature
+5. ✅ **Prepared**: F-Droid submission with reproducible builds
+
+## Description for PR
+
+### Critical Bug Fixes
+
+#### 1. Dependency Fix (Issue #181)
+Fixed build failure caused by unavailable `ergo-appkit` SNAPSHOT dependency. Updated to stable release 5.0.0 from Maven Central.
+
+#### 2. Windows Desktop JVM Launch Fix (CRITICAL)
+**Problem**: Windows x64 users unable to start application after upgrade - "Failed to launch JVM" error
+**Solution**: Added JVM memory options and module access flags to jpackage configuration
+- Memory: `-Xmx2048m -Xms512m`
+- Module access for Java 11+ compatibility
+- Prevents startup failures and OutOfMemoryErrors
+
+This is a **blocking issue** affecting all Windows desktop users.
+
+#### 3. Java 21/24 Build Compatibility Fix (CRITICAL)
+**Problem**: Build fails on Windows 11 with JDK 21/24 - "Unsupported class file major version 65/68"
+**Solution**: Upgraded Gradle from 7.4 to 8.11.1
+- Gradle 7.4 only supports Java 8-17
+- Gradle 8.11.1 fully supports Java 8-24
+- No code changes required
+- All plugins remain compatible
+
+This is a **blocking issue** for developers using Java 21 or newer (including Java 24).
+
+### New Features
+
+#### 3. ErgoAuth Address Generation
+Implemented `generateAddressLink` feature improving dApp integration UX:
+- **Before**: Manual address entry or double QR scanning required
+- **After**: Single QR scan, wallet automatically provides address with cryptographic proof
+- **URI Pattern**: `ergoauth://${url}/generateAddressLink/${uuid}/#P2PK_ADDRESS#/`
+- **Response**: `{signedMessage, proof, changeAddress, addresses[]}`
+
+### Improvements
+
+#### 5. F-Droid Distribution Preparation
+Complete preparation for F-Droid submission including:
+- F-Droid metadata and Fastlane descriptions
+- Reproducible build scripts
+- SOURCE_DATE_EPOCH configuration
+
+#### 6. Scala Upgrade Strategy Documentation
+Comprehensive documentation of 5 paths to upgrade from Scala 2.11, addressing RoboVM constraints.
+
+## Files Changed
+- `common-jvm/build.gradle` - Dependency update
+- `build.gradle` - Repository cleanup
+- `gradle/wrapper/gradle-wrapper.properties` - **Gradle 8.11.1 upgrade**
+- `desktop/deploy/jpackage.cfg` - **JVM launch fix**
+- `common-jvm/src/main/java/org/ergoplatform/uilogic/ergoauth/` - ErgoAuth feature
+- `android/src/main/res/values/strings.xml` - String resources
+- `ios/resources/i18n/strings.properties` - String resources
+- F-Droid preparation files
+- Documentation files
+
+## Testing Required
+- ✅ Build succeeds
+- ✅ No compilation errors
+- ⏳ Build on Windows 11 with JDK 21
+- ⏳ Windows MSI installer with JVM fix (requires Windows environment)
+- ⏳ ErgoAuth address generation with live dApp (requires dApp integration)
+
+## Impact
+- **High Priority**: Java 21 build fix unblocks modern Java developers
+- **High Priority**: Windows JVM launch fix unblocks all Windows desktop users
+- **Medium Priority**: ErgoAuth feature improves dApp ecosystem UX
+- **Low Priority**: F-Droid preparation expands distribution channels
+
+## Backward Compatibility
+✅ All changes are backward compatible
+✅ No breaking API changes
+✅ Existing features unchanged
+
+---
+
+**Ready for review and merge**


The PR title and description do not match the actual changes in this pull request. The title mentions "Add Multisig EIP-41/EIP-11 Support Across Platforms" and the description extensively details multisig wallet implementation, but the actual changes are primarily focused on:

Gradle upgrade (7.4 to 8.11.1) for Java 21 support

Windows JVM launch fixes (jpackage configuration)

F-Droid preparation (metadata, build scripts)

ErgoAuth address generation feature

UI improvements (storage rent warnings, security warnings)

Database schema additions for multisig (but no implementation)

While multisig database tables are added, there is no actual multisig wallet creation wizard, transaction management UI, or conflict detection logic as described. The PR appears to be a collection of infrastructure fixes and preparations rather than the multisig feature implementation described.

+                    // Create a unique signing message for address proof
+                    val addressList = walletAddresses.map { it.publicAddress }
+                    val changeAddress = addressList.first() // Use first address as change address
+                    val signedMessage = prefix + "ADDRESS_REQUEST" + ergAuthRequest.requestHost + suffix


In the ErgoAuth address request handling, the signed message hardcodes "ADDRESS_REQUEST" as a constant string. This should be extracted as a constant at the file or class level for better maintainability and to avoid potential inconsistencies if used elsewhere.

+                database.execSQL("CREATE TABLE IF NOT EXISTS `multisig_transactions` (`id` INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL, `wallet_first_address` TEXT NOT NULL, `tx_id` TEXT, `state` INTEGER NOT NULL, `memo` TEXT, `last_json` TEXT, `depends_on_tx_ids` TEXT, `last_change` INTEGER NOT NULL)")
+                database.execSQL("CREATE INDEX IF NOT EXISTS `index_multisig_transactions_wallet_first_address` ON `multisig_transactions` (`wallet_first_address`)")

+            }
+        }


The database migration adds multisig-related tables and wallet_type column, but there's no corresponding DOWN migration or rollback strategy documented. If this migration needs to be reverted, there's no clear path. Consider documenting the rollback procedure or adding a corresponding migration file for reverting these schema changes.

+                .setPositiveButton(R.string.zxing_button_ok) { _, _ ->
+                    prefs.storageRentShown = true
+                }

+                }
+                .setCancelable(false)
+                .show()


The storage rent info dialog is shown only once and uses a preference flag. However, the logic shows the dialog on every app resume if the flag is not set. This could be problematic if the user dismisses the app during the dialog display without clicking a button, as the dialog would show again on next launch. Consider setting the flag as soon as the dialog is shown, not just when buttons are clicked.

Suggested change

.setPositiveButton(R.string.zxing_button_ok) { _, _ ->

prefs.storageRentShown = true

}

.setNegativeButton(R.string.button_dont_show_again) { _, _ ->

prefs.storageRentShown = true

The documentation file JAVA21_GRADLE_FIX.md contains duplicate content and formatting issues. Lines 256-267 repeat information about Gradle 8.11.1 benefits, and lines 269-274 contain incomplete/malformed text including "es required" and "11.1 downloads successfully". This appears to be a merge conflict or copy-paste error that wasn't cleaned up.

+                        false
+                    }


The node API testing logic attempts to validate blockchain API availability by testing with hardcoded addresses. However, this test makes an actual API call during settings display, which could cause performance issues or delays when viewing connection settings. Consider making this check asynchronous or caching the result, as this appears to be executed synchronously during the node info retrieval flow.

+            val tokenInfo = tokenInformation[it.tokenId]
+            tokenInfo == null || tokenInfo.thumbnailType == THUMBNAIL_TYPE_NONE
+        }
+
+    val nftsList
+        get() = fullTokensList.filter {

+            tokenInfo != null && (tokenInfo.thumbnailType == THUMBNAIL_TYPE_NFT_IMG || 
+                                  tokenInfo.thumbnailType == THUMBNAIL_TYPE_NFT_VID)

+            tokenInfo != null && tokenInfo.thumbnailType == THUMBNAIL_TYPE_NFT_AUDIO
+        }


The token list filtering logic introduces three new computed properties (regularTokensList, nftsList, audioNftsList) that filter the fullTokensList. However, these properties don't apply the tokenFilterMap that's used by the existing tokensList property. This creates inconsistency where the general tokensList respects user filter preferences, but the categorized lists don't. Consider either applying the filter to all lists or documenting why the categorized lists intentionally bypass filtering.

+                        val balanceResponse = blockchainApi.getBalance(testAddress).execute()


The test addresses used for blockchain API validation are hardcoded and assumed to be valid mainnet/testnet addresses. If these addresses ever become invalid or the blockchain state changes such that they return unexpected responses, the API availability check would fail incorrectly. Consider using well-known genesis or burn addresses that are guaranteed to exist, or implement a more robust API availability check that doesn't depend on specific address states.

+                .setCancelable(false)
+                .show()


The storage rent dialog is configured with setCancelable(false), forcing users to interact with it. This creates a poor user experience, especially for users who may already be aware of storage rent. Consider allowing users to dismiss the dialog by tapping outside (setCancelable(true)) and treating dismissal the same as clicking "Don't show again".
