Praktik Terbaik

1. Izin: Minta izin lokasi sebelum memindai jaringan
2. Penanganan Kesalahan: Selalu gabungkan operasi WiFi dalam blok coba-tangkap
3. Umpan Balik Pengguna: Menampilkan indikator pemuatan selama operasi jaringan
4. Keamanan: Jangan pernah menyimpan kata sandi WiFi dalam teks biasa
5. Pengujian: Uji pada perangkat nyata karena API WiFi mungkin tidak berfungsi di emulator

Perbedaan Platform

iOS

• Membutuhkan izin lokasi untuk memindai jaringan
• Tidak dapat terprogram terhubung ke jaringan (akan membuka Pengaturan)
• Akses terbatas ke detail jaringan

Android

• Kontrol WiFi terprogram penuh
• Membutuhkan izin lokasi untuk pemindaian jaringan
• Dapat menghubungkan/memutuskan sambungan secara terprogram

Pemecahan masalah

Masalah Umum

Pemindaian kembali kosong: Periksa apakah izin lokasi diberikan Tidak dapat terhubung ke jaringan: Pastikan kata sandi benar dan jaringan berada dalam jangkauan getWifiInfo gagal: Pastikan perangkat terhubung ke jaringan WiFi Izin ditolak: Tambahkan izin yang diperlukan ke file konfigurasi platform
