## 📋 APA YANG SUDAH DIPERBAIKI?
|
|
|
|
### ✅ Masalah 1: Tidak Ada Error Handling
|
|
```
|
|
❌ SEBELUM: Aplikasi crash saat NPM duplikat
|
|
✅ SESUDAH: Ditangani dengan graceful, user dapat feedback yang jelas
|
|
```
|
|
|
|
### ✅ Masalah 2: Validasi Input Minimal
|
|
```
|
|
❌ SEBELUM: NPM "ABC" atau password "123" bisa diterima
|
|
✅ SESUDAH: Ditolak dengan pesan spesifik:
|
|
- NPM harus 8+ digit angka
|
|
- Password minimal 6 karakter
|
|
```
|
|
|
|
### ✅ Masalah 3: Tidak Ada Logging
|
|
```
|
|
❌ SEBELUM: Sulit debug, tidak tahu apa yang salah
|
|
✅ SESUDAH: Semua error di-log, bisa buka Logcat untuk lihat detail
|
|
```
|
|
|
|
### ✅ Masalah 4: Resource Leak
|
|
```
|
|
❌ SEBELUM: Cursor tidak dijamin ditutup
|
|

## 🎓 BELAJAR DARI PERBAIKAN INI
|
|
|
|
### Error Handling Pattern
|
|
```kotlin
|
|
fun functionName(): Boolean {
|
|
return try {
|
|
// Main logic
|
|
result
|
|
} catch (e: Exception) {
|
|
android.util.Log.e("TAG", "Error: ${e.message}")
|
|
false // Safe return
|
|
}
|
|
}
|
|
```
|
|
|
|
### Validation Pattern
|
|
```kotlin
|
|
when {
|
|
field1.isEmpty() -> showError("Field 1 kosong")
|
|
field2.isInvalid() -> showError("Field 2 invalid")
|
|
field3.exists() -> showError("Field 3 sudah ada")
|
|
else -> proceed()
|
|
}
|
|
```
|
|
|
|
### Resource Management
|
|
```kotlin
|
|
try {
|
|
val cursor = db.query(...)
|
|
// Use cursor
|
|
cursor.close() // Guaranteed to close
|
|
} catch (e: Exception) {
|
|
// Handle error
|
|
}
|
|
```
