## 🔍 Key Technical Decisions
|
|
|
|
### **1. Timestamp Handling**
|
|
- **Decision**: Separate `fetchedAt` (immutable) and `scheduledAt` (mutable)
|
|
- **Rationale**: Prevents TTL violations and ensures data integrity
|
|
- **Implementation**: Custom JsonDeserializer for Gson compatibility
|
|
|
|
### **2. Recovery Mechanisms**
|
|
- **Decision**: Dual recovery (BootReceiver + App Startup)
|
|
- **Rationale**: Maximum reliability across Android versions and OEMs
|
|
- **Implementation**: BootReceiver for ideal case, app startup as fallback
|
|
|
|
### **3. Storage Safety**
|
|
- **Decision**: `ensureStorageInitialized()` helper method
|
|
- **Rationale**: Prevents null pointer exceptions
|
|
- **Implementation**: Called at start of all plugin methods
|
|
|
|
### **4. Permission Management**
|
|
- **Decision**: Handle exact alarm permissions for Android 12+
|
|
- **Rationale**: Required for reliable notification scheduling
|
|
- **Implementation**: Settings deep-link with proper intent handling
|
|
|
