## 🎯 PROBLEMS FIXED
|
|
|
|
### **Before** ❌
|
|
```
|
|
❌ No error handling → Application crashes on errors
|
|
❌ Minimal validation → Invalid data accepted
|
|
❌ No logging → Hard to debug
|
|
❌ Resource leaks → Database/cursor not properly closed
|
|
❌ Generic error messages → User doesn't know what's wrong
|
|
❌ No documentation → Cannot learn from code
|
|
```
|
|
|
|
### **After** ✅
|
|
```
|
|
✅ Comprehensive error handling → Graceful error recovery
|
|
✅ 7 validation rules → Invalid data rejected upfront
|
|
✅ Full logging system → Easy debugging via Logcat
|
|
✅ Proper resource management → Safe database access
|
|
✅ Specific error messages → Clear user feedback
|
|
✅ Complete documentation → Easy to understand & maintain
|
|

## 🔍 IF SOMETHING GOES WRONG
|
|
|
|
### **Scenario 1: Registrasi Gagal**
|
|
```
|
|
1. Buka Logcat (View → Tool Windows → Logcat)
|
|
2. Filter: "DatabaseHelper"
|
|
3. Lihat ERROR message
|
|
4. Baca REGISTRATION_TROUBLESHOOTING.md
|
|
5. Follow solution
|
|
```
|
|
|
|
### **Scenario 2: App Crash**
|
|
```
|
|
1. Baca error di Logcat
|
|
2. Check BEFORE_AFTER_COMPARISON.md untuk context
|
|
3. Lihat METHOD yang related
|
|
4. Share error message jika masih stuck
|
|
```
|
|
|
|
### **Scenario 3: Validation Tidak Bekerja**
|
|
```
|
|
1. Verify inputs sesuai rules di VALIDATION RULES section

## 💡 KEY LEARNINGS
|
|
|
|
### **What Changed in Code**
|
|
|
|
#### DatabaseHelper.kt
|
|
```kotlin
|
|
// ❌ BEFORE: No error handling
|
|
fun addUser(...) {
|
|
val result = db.insert(...)
|
|
return result != -1L // CRASH jika ada exception
|
|
}
|
|
|
|
// ✅ AFTER: Full error handling
|
|
fun addUser(...) {
|
|
return try {
|
|
val result = db.insert(...)
|
|
result != -1L
|
|
} catch (e: Exception) {
|
|
android.util.Log.e("DatabaseHelper", "Error: ${e.message}")
|
|
false // Safe fallback
|
|
}
|
|
}
|
|
```
|
|
|
|
#### MainActivity.kt (RegisterScreen)
|
|
```kotlin
|
|
// ❌ BEFORE: Nested if-else, minimal validation
|
|
if (username.isNotEmpty() && npm.isNotEmpty() && ...) {
|
|
if (password.length < 6) { ... }
|
|
else if (db.userExists(npm)) { ... }
|
|
else { ... }
|
|
}
|
|
|
|
// ✅ AFTER: Clean when expression, comprehensive validation
|
|
when {
|
|
username.isBlank() -> Toast.makeText(..., "Nama tidak boleh kosong", ...)
|
|
npm.length < 8 -> Toast.makeText(..., "NPM harus minimal 8 karakter", ...)
|
|
!npm.all { it.isDigit() } -> Toast.makeText(..., "NPM hanya angka", ...)
|
|
password.length < 6 -> Toast.makeText(..., "Password minimal 6 karakter", ...)
|
|
db.userExists(npm) -> Toast.makeText(..., "NPM sudah terdaftar", ...)
|
|
else -> { /* proceed */ }
|
|
}
|
|
```
