# ✅ FIX: Menu Riwayat Absensi - Close App Issue
|
|
|
|
## 🔍 Problem Identified
|
|
**Issue**: Ketika mengklik "Riwayat Absensi" di MenuScreen, aplikasi close/crash
|
|
|
|
## 🔴 Root Causes
|
|
|
|
### 1. **Insufficient Error Handling di History Route**
|
|
```kotlin
|
|
// ❌ Before: Minimal error handling
|
|
composable("history") {
|
|
val npmForHistory = currentNpm ?: ""
|
|
if (!hasValidNpm) {
|
|
Box { Text("NPM tidak ditemukan...") }
|
|
} else {
|
|
val attendanceList by repository.getAttendanceByNpm(npmForHistory)
|
|
.collectAsState(initial = emptyList())
|
|
HistoryScreen(...)
|
|
}
|
|
}
|
|
```
|
|
**Problem**:
|
|
- Simple error message tidak user-friendly
|
|
- Tidak ada retry mechanism
|
|
- No visual feedback untuk error states
|
|
|
|
### 2. **Missing UI Feedback**
|
|
- Tidak ada loading state
|
|
- Tidak ada visual distinction untuk error vs empty
|
|
- Button "Kembali" tidak tersedia di error state
|
|
|
|
### 3. **Incomplete Error Handling**
|
|
- Only checks for empty npm
|
|
- Doesn't handle database access errors
|
|
- No try-catch wrapper untuk unexpected exceptions
|
|
|

|
|
## ✅ Solutions Applied
|
|
|
|
### 1. **Enhanced Error States UI**
|
|
```kotlin
|
|
composable("history") {
|
|
if (!hasValidNpm) {
|
|
// Beautiful error UI dengan icon & button
|
|
Box {
|
|
Column {
|
|
Text("⚠️ NPM tidak ditemukan")
|
|
Text("Silakan login ulang...")
|
|
Button("Kembali ke Menu")
|
|
}
|
|
}
|
|
} else {
|
|
try {
|
|
val attendanceList by repository.getAttendanceByNpm(npmForHistory)
|
|
.collectAsState(initial = emptyList())
|
|
HistoryScreen(...)
|
|
} catch (e: Exception) {
|
|
// Error UI untuk database access errors
|
|
Box {
|
|
Column {
|
|
Text("❌ Terjadi Kesalahan")
|
|
Text("${e.message}")
|
|
Button("Kembali ke Menu")
|
|
}
|
|
}
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
### 2. **Added Defensive Styling**
|
|
```kotlin
|
|
Box(
|
|
modifier = Modifier
|
|
.fillMaxSize()
|
|
.background(MaterialTheme.colorScheme.background),
|
|
contentAlignment = Alignment.Center
|
|
)
|
|
```
|
|
|
|
### 3. **Better User Feedback**
|
|
- ✅ Clear error messages
|
|
- ✅ Helpful instructions
|
|
- ✅ Back button untuk recovery
|
|
- ✅ Emoji icons untuk visual clarity
|
|
|
|
### 4. **Added Required Imports**
|
|
```kotlin
|
|
import androidx.compose.foundation.background
|
|
import androidx.compose.foundation.layout.Column
|
|
import androidx.compose.foundation.layout.Spacer
|
|
import androidx.compose.foundation.layout.height
|
|
import androidx.compose.foundation.layout.padding

## 💡 Technical Details
|
|
|
|
### Error Handling Flow
|
|
```
|
|
Click "Riwayat Absensi" (from MenuScreen)
|
|
↓
|
|
Check currentNpm validity
|
|
├─ If empty → Show npm warning + back button
|
|
└─ If valid → Try to fetch data
|
|
├─ Success → HistoryScreen
|
|
└─ Error → Show error message + back button
|
|
```
|
|
|
|
### State Management
|
|
- `currentNpm` and `currentNama` from preferences
|
|
- `attendanceList` from collectAsState
|
|
- Error states handled via try-catch
|
|
