PENJELASAN PERMISSIONS:
1. ACCESS_FINE_LOCATION & ACCESS_COARSE_LOCATION
- Untuk mendapatkan koordinat GPS
- FINE = Akurasi tinggi (GPS)
- COARSE = Akurasi rendah (Network)
2. CAMERA
- Untuk mengambil foto selfie
3. INTERNET & ACCESS_NETWORK_STATE
- Untuk kirim data ke webhook
- Cek status koneksi
4. WRITE/READ_EXTERNAL_STORAGE
- Optional, untuk simpan foto ke storage
- Hanya untuk Android < 10
5. usesCleartextTraffic="true"
- Mengizinkan HTTP (bukan HTTPS)
- Diperlukan jika webhook menggunakan HTTP
- Untuk production, sebaiknya gunakan HTTPS
6. screenOrientation="portrait"
- Mengunci orientasi portrait
- Bisa dihapus jika mau support landscape
CATATAN PENTING:
- Semua permission di atas sudah di-request secara runtime di code
- User harus approve permission saat pertama kali buka aplikasi
- Jika permission ditolak, fitur terkait tidak akan berfungsi

* 3. Untuk production, bisa dikembangkan dengan:
* - Ambil data dari API/Database
* - Filtering berdasarkan hari
* - Notifikasi jadwal kuliah hari ini
* - Link ke Google Calendar
*
* 4. Bisa juga ditambahkan fitur:
* - Absensi langsung dari jadwal
* - Informasi tugas/quiz
* - Materi kuliah
