Status Saat Ini

• ❌ Device fisik NOT detected di ADB
• ✅ Android SDK sudah terinstall
• 📱 HP Anda punya hotspot & sudah enabled

---

Solusi Step-by-Step

Step 1: Enable USB Debugging di HP Android

1. Buka Settings → About Phone
2. Tap Build Number sebanyak 7 kali sampai muncul "You are now a developer"
3. Kembali ke Settings → Developer Options (muncul di bawah)
4. Cari USB Debugging dan nyalakan (toggle ON)
5. Jika muncul popup security, tap Allow

Step 2: Hubungkan Device via USB

1. Cabut kabel USB dari HP (jika sudah terhubung)
2. Tunggu 5 detik
3. Hubungkan kembali ke desktop dengan mode MTP atau File Transfer
   • Jika ada popup di HP, pilih "File Transfer" atau "MTP"
4. Desktop akan mendeteksi HP sebagai storage device

Step 3: Izinkan USB Debugging

1. Di HP, jika ada popup "Allow USB debugging from this computer?"
   • Centang ✓ "Always allow from this computer"
   • Tap Allow
2. Jika tidak ada popup, Anda mungkin perlu:
   • Cabut USB lagi
   • Buka DevTools di HP
   • Hubungkan ulang USB
   • Popup akan muncul

Step 4: Verify Device terdeteksi

Buka PowerShell dan jalankan:

& "C:\Users\MICKO\AppData\Local\Android\sdk\platform-tools\adb.exe" devices

Expected output: Device ID Anda akan muncul:

List of devices attached
R58M80DLXXX      device

Step 5: Jalankan Flutter App di Device

cd C:\laragon\www\TA\spk_mobile
flutter devices        # Verify device terdeteksi
flutter run -d <device-id>

🚨 Jika Masih Tidak Terdeteksi

Cek USB Driver

1. Buka Device Manager (Win + X → Device Manager)
2. Cari device HP Anda (mungkin di "Other devices" atau "Portable Devices")
3. Jika ada ⚠️ warning icon:
   • Right-click → Update driver
   • Pilih "Browse my computer for drivers"
   • Navigasi ke: C:\Users\MICKO\AppData\Local\Android\sdk\usb_driver
   • Klik Next dan install

Reset ADB Connection

& "C:\Users\MICKO\AppData\Local\Android\sdk\platform-tools\adb.exe" kill-server
& "C:\Users\MICKO\AppData\Local\Android\sdk\platform-tools\adb.exe" start-server
& "C:\Users\MICKO\AppData\Local\Android\sdk\platform-tools\adb.exe" devices

Coba Port USB Lain

• Lepas USB dari port yang digunakan
• Coba port USB lain di desktop (preferably USB 3.0)
• Ulangi deteksi

Wireless ADB (Jika USB tidak bisa)

Setelah device pernah terdeteksi via USB sekali:

# Set device ke wireless mode (ganti XXX dengan device ID)
& "C:\Users\MICKO\AppData\Local\Android\sdk\platform-tools\adb.exe" tcpip 5555

# Disconnect USB

# Connect via IP (ganti 192.168.x.x dengan IP device di hotspot)
& "C:\Users\MICKO\AppData\Local\Android\sdk\platform-tools\adb.exe" connect 192.168.x.x:5555

---

Hotspot Setup

• ✅ Device hotspot ON
• ✅ Desktop terkoneksi ke hotspot device
• ✅ Firewall tidak block port 5555 (untuk wireless ADB)

📞 Common Issues & Fixes

Masalah	Solusi
Popup "Allow USB debugging" tidak muncul	Cabut USB, tunggu 10s, pasang ulang + buka Developer Options di HP dulu
USB Driver error	Install dari C:\Users\MICKO\AppData\Local\Android\sdk\usb_driver
Device sudah terdeteksi tapi app crash	Update Flutter: flutter upgrade & flutter pub get di spk_mobile folder
Koneksi timeout saat flutter run	Device & desktop harus di network sama, cek IP: ipconfig
