Release Date: 2025-11-14

Summary #

This release fixes two critical crashes affecting SMS functionality on Android devices and introduces comprehensive dual SIM support. All three issues (#12, #14, #16) have been resolved with proper testing and documentation.

Bug Fixes #

CRITICAL: Permission Handling Crash #14

Issue: IllegalStateException: Reply already submitted crash when multiple plugins request permissions.

Root Cause: The permission callback logic used AND operator (&&) which incorrectly processed permission results from other plugins, causing double-reply attempts on the method channel.

Fix:

• Separated request code validation from action initialization check
• Added early return when request code doesn't match
• Prevents cross-plugin permission callback interference

Technical Details:

• Modified: SmsMethodCallHandler.kt:368-381
• Changed from: if (requestCode != this.requestCode && !this::action.isInitialized)
• Changed to: Two separate if statements with early returns

CRITICAL: SmsManager Initialization Failure #12

Issue: PlatformException(failed_to_fetch_sms, Flutter Telephony: Error getting SmsManager) on Android 11 and below.

Root Cause: Code used getSystemService(context, SmsManager::class.java) which only works on Android 12+ (API 31+), returning null on older versions.

Fix:

• Added API level check for SmsManager initialization
• Android 12+ (API 31+): Use getSystemService(context, SmsManager::class.java)
• Android < 12: Use deprecated SmsManager.getDefault()
• Added graceful fallback with logging when subscription-specific manager creation fails

Technical Details:

• Modified: SmsController.kt:142-179
• Based on solution from PR shounakmulay/Telephony#153

New Features #

Dual SIM Support #16

Complete implementation of dual SIM functionality for devices with multiple SIM cards.

New API Methods:

// Get all active SIM subscriptions
Future<List<SubscriptionInfo>> getSubscriptionList()

New Data Classes:

• SubscriptionInfo - Represents a SIM card with properties:
  • subscriptionId (int?) - Unique ID for sending SMS
  • simSlotIndex (int?) - Physical slot (0, 1, etc.)
  • carrierName (String?) - Operator name (e.g., "Verizon")
  • displayName (String?) - User-assigned name
  • countryIso (String?) - Country code (e.g., "us")
  • phoneNumber (String?) - Phone number (if available)

Enhanced Methods:

• sendSms() now accepts optional subscriptionId parameter
• Default behavior unchanged (uses default SIM)

Requirements:

• Android API 22+ (Lollipop MR1)
• READ_PHONE_STATE permission in AndroidManifest.xml

Technical Implementation:

• Android: SmsController.kt:270-298 - Native implementation using SubscriptionManager
• Dart: telephony.dart:562-579 - Dart API and data model
• Constants: GET_SUBSCRIPTION_LIST method added
• Enum: SmsAction.GET_SUBSCRIPTION_LIST added to action types

Improvements #

Code Quality

• Removed 2 completed TODO comments from build.gradle
• Clarified that debug signing in example app is intentional
• Added inline documentation for complex logic
• Improved error messages with context

Documentation

• README.md: Added comprehensive "Dual SIM Support" section with examples
• CHANGELOG.md: Detailed release notes with technical details
• Example App: Complete UI demonstrating dual SIM functionality
• All new APIs have full dartdoc comments

Testing

Added 3 new unit tests for dual SIM functionality:

1. subscription list for dual SIM - Tests with 2 SIM cards
2. subscription list returns empty list when no SIMs - Edge case testing
3. subscription list handles null response - Null safety testing

Test Coverage: All SubscriptionInfo properties validated

Example Application

Enhanced example/lib/main.dart with:

• SIM cards list display with all properties
• Per-SIM "Send SMS" buttons
• Refresh subscription list button
• Card-based UI layout for better UX
• Error handling with user feedback

Breaking Changes #

None - This release is fully backward compatible.

Migration Guide #

For Dual SIM Support

If you want to use the new dual SIM features:

1. Add permission to AndroidManifest.xml:

<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

2. Request permission at runtime:

await telephony.requestPhonePermissions;

3. Get subscriptions and send SMS:

final subs = await telephony.getSubscriptionList();
if (subs.isNotEmpty) {
  await telephony.sendSms(
    to: "1234567890",
    message: "Hello",
    subscriptionId: subs[0].subscriptionId!,
  );
}
