🔄 MAINTENANCE & UPDATE GUIDE

📋 Overview

Panduan untuk developer yang ingin membuat update, bug fix, atau enhancement di masa depan.

🐛 Bug Fix Procedure

Step 1: Identify the Bug

Which screen?     → LoginScreen, MenuScreen, AttendanceScreen, SuccessScreen
What's wrong?     → Visual, Logic, Navigation, Data, Other
Severity?         → Critical, High, Medium, Low
Reproducible?     → Always, Sometimes, Rarely, Never

Step 2: Find Relevant Documentation

Check QUICK_REFERENCE_UI.md - quick overview
Check specific screen docs in UI_IMPLEMENTATION_SUMMARY.md
Check TESTING_GUIDE.md - expected behavior
Check MOCKUP_IMPLEMENTATION.md - design specs

Step 3: Locate Code File

LoginScreen issues     → app/src/main/java/.../presentation/screens/LoginScreen.kt
MenuScreen issues      → app/src/main/java/.../presentation/screens/MenuScreen.kt
AttendanceScreen issues → app/src/main/java/.../presentation/screens/AttendanceScreen.kt
SuccessScreen issues   → app/src/main/java/.../presentation/screens/SuccessScreen.kt
Navigation issues      → app/src/main/java/.../MainActivity.kt
Mata kuliah issues     → AttendanceScreen.kt + MainActivity.kt

Step 4: Make Changes

// Before making changes:
1. Read the complete function/composable
2. Understand the current flow
3. Identify root cause
4. Make minimal changes only

// Example bug fix structure:
@Composable
fun ScreenName() {
    // ... existing code ...
    
    // BUG FIX: Description of bug and fix
    // Old: if (isLoading) { ... }
    // New: if (isLoading && photo != null) { ... }
    
    // ... rest of code ...
}

Step 5: Test the Fix

1. Follow relevant test cases from TESTING_GUIDE.md
2. Test the specific feature that was fixed
3. Test surrounding features (regression)
4. Test navigation related to the bug
5. Document test results

Step 6: Update Documentation (if needed)

If behavior changed:
  → Update TESTING_GUIDE.md
  → Update relevant doc file
  → Update QUICK_REFERENCE_UI.md

If visual changed:
  → Update MOCKUP_IMPLEMENTATION.md
  → Update UI_IMPLEMENTATION_SUMMARY.md

✨ Feature Addition Procedure

Step 1: Plan the Feature

Feature name:     _________________
Affects screens:  _________________
New files needed: _________________
Related features: _________________
Database changes: _________________

Step 2: Study Existing Patterns

Pattern 1: Input Field (Like Mata Kuliah)

// Location: AttendanceScreen.kt, line ~340

Card(
    modifier = Modifier.fillMaxWidth(),
    colors = CardDefaults.cardColors(
        containerColor = Color(0xFF2E7D32).copy(alpha = 0.1f)
    ),
    shape = RoundedCornerShape(8.dp)
) {
    Column(modifier = Modifier.padding(12.dp)) {
        // Icon + Title
        Row(
            modifier = Modifier.fillMaxWidth(),
            verticalAlignment = Alignment.CenterVertically,
            horizontalArrangement = Arrangement.spacedBy(8.dp)
        ) {
            Icon(Icons.Default.Info, ...)
            Text("Field Name", style = MaterialTheme.typography.labelMedium)
        }
        Spacer(modifier = Modifier.height(8.dp))
        
        // Input
        OutlinedTextField(
            value = fieldValue,
            onValueChange = { fieldValue = it },
            modifier = Modifier.fillMaxWidth().height(40.dp),
            placeholder = { Text("Placeholder", fontSize = 12.sp) },
            singleLine = true,
            enabled = !isLoading
        )
    }
}

Pattern 2: Action Button

Button(
    onClick = { /* action */ },
    modifier = Modifier
        .fillMaxWidth()
        .height(44.dp),
    enabled = !isLoading && condition,
    colors = ButtonDefaults.buttonColors(
        containerColor = Color(0xFF2E7D32),
        contentColor = Color.White
    ),
    shape = RoundedCornerShape(8.dp)
) {
    if (isLoading) {
        CircularProgressIndicator(modifier = Modifier.size(18.dp), ...)
    } else {
        Icon(Icons.Default.Something, ..., modifier = Modifier.size(16.dp), ...)
        Spacer(modifier = Modifier.width(8.dp))
        Text("BUTTON TEXT", fontSize = 14.sp, fontWeight = FontWeight.Bold)
    }
}

Pattern 3: Status Card

Card(
    modifier = Modifier.fillMaxWidth(),
    colors = CardDefaults.cardColors(
        containerColor = Color(0xFF2E7D32).copy(alpha = 0.1f)
    ),
    shape = RoundedCornerShape(8.dp)
) {
    Column(modifier = Modifier.padding(12.dp)) {
        Row(
            modifier = Modifier.fillMaxWidth(),
            verticalAlignment = Alignment.CenterVertically,
            horizontalArrangement = Arrangement.spacedBy(8.dp)
        ) {
            Icon(
                Icons.Default.CheckCircle,
                tint = if (isValid) Color(0xFF4CAF50) else Color(0xFFf44336),
                modifier = Modifier.size(20.dp)
            )
            Text(
                text = if (isValid) "Status: Valid" else "Status: Invalid",
                style = MaterialTheme.typography.labelMedium,
                color = if (isValid) Color(0xFF4CAF50) else Color(0xFFf44336)
            )
        }
    }
}

Step 3: Implement Feature

1. Create input field or button following pattern
2. Add state variable (var feature by remember { mutableStateOf(...) })
3. Add validation logic
4. Add event handler
5. Update submit validation if needed
6. Test with existing flows

// In MainActivity.kt

composable("new_screen") {
    if (currentNpm != null && currentNama != null) {
        NewScreen(
            npm = currentNpm!!,
            nama = currentNama!!,
            onNavigateBack = {
                navController.navigateUp()
            }
        )
    }
}

// Add route from existing screen:
onNewFeature = {
    navController.navigate("new_screen")
}

Step 5: Test Feature

1. Unit test (if applicable)
2. Integration test with existing screens
3. Navigation test
4. Data persistence test
5. Error handling test

Step 6: Document Feature

Create/Update:
  1. QUICK_REFERENCE_UI.md - add to feature list
  2. New feature doc (like MATA_KULIAH_FEATURE.md)
  3. TESTING_GUIDE.md - add test cases
  4. IMPLEMENTATION_CHECKLIST.md - update status
  5. MOCKUP_IMPLEMENTATION.md - if visual change

🎨 UI/Design Update Procedure

Step 1: Identify What Changed

What needs to change?
  [ ] Colors (#2E7D32, #FFFFFF, #4CAF50, #f44336)
  [ ] Spacing (12dp, 16dp, 24dp)
  [ ] Font sizes
  [ ] Border radius
  [ ] Icons
  [ ] Layout structure

Step 2: Update Colors Globally

// If primary color needs change:
// Search for: Color(0xFF2E7D32)
// Replace with: Color(0xFFNEWCOLOR)

// Files to check:
// - All screen files
// - MainActivity.kt
// - Any theme files

Step 3: Update Typography

// If font size needs change:
// Example: fontSize = 14.sp → fontSize = 16.sp

// Common sizes used:
// Button text: 14sp (bold)
// Labels: 12-14sp
// Titles: 20-28sp
// Body: 14-16sp

Step 4: Update Spacing

// If padding needs change:
// Example: padding = 16.dp → padding = 20.dp

// Common spacing:
// Inside cards: 12dp
// Between items: 12-16dp
// Page margins: 24dp
// Border radius: 8-12dp

Step 5: Verify Consistency

After changes, check:
[ ] All screens have same primary color
[ ] All buttons same size and style
[ ] All cards same padding and radius
[ ] Text hierarchy consistent
[ ] Icons same size throughout
[ ] Colors match design system

Step 6: Update Documentation

Update these files:
  1. MOCKUP_IMPLEMENTATION.md - design specs
  2. UI_IMPLEMENTATION_SUMMARY.md - color section
  3. QUICK_REFERENCE_UI.md - visual changes
  4. TESTING_GUIDE.md - visual test cases

📦 Database/Backend Changes

If Mata Kuliah Storage Changes

// File: Attendance.kt
data class Attendance(
    val npm: String,
    val nama: String,
    val latitude: Double,
    val longitude: Double,
    val timestamp: Long,
    val fotoBase64: String,
    val mataPelajaran: String,  // Already exists!
    val status: String
)

// No changes needed if field already exists

If New Field Added

// 1. Update Attendance model
data class Attendance(
    // ... existing fields ...
    val mataPelajaran: String,
    val newField: String  // ← Add new field
)

// 2. Update Room DAO
// 3. Update AttendanceRepository
// 4. Update N8N webhook format
// 5. Update database migration (if needed)
// 6. Update TESTING_GUIDE.md

If N8N Integration Changes

1. Update repository.sendToN8n() in AttendanceRepository.kt
2. Update JSON structure in N8N_WEBHOOK_GUIDE.md
3. Test with actual N8N endpoint
4. Verify data arrives correctly
5. Update documentation
