Release Notes v23.9 (2026040401)

Tanggal: 4 April 2026

Focus: Fix False-Positive Violation Detection saat Pindah Soal

Masalah yang Diperbaiki

HP siswa terdeteksi pelanggaran (violation) saat pindah soal, padahal tidak melakukan kecurangan. Terutama terjadi pada HP dengan spesifikasi rendah (RAM 2-3 GB) dan koneksi internet lambat.

Perubahan

Plugin Moodle (`proguard.js`)

1. Debounce pada Visibility Change

Sebelum: visibilitychange ke hidden langsung trigger violation

Sesudah: Ditambahkan delay 2 detik. Jika halaman kembali visible sebelum 2 detik (misal karena sedang loading soal baru), violation dibatalkan

Alasan: WebView yang sedang load halaman bisa memicu visibilitychange secara internal

2. Debounce pada Focus Polling

Sebelum: Pengecekan document.hasFocus() setiap 1.5 detik langsung trigger violation

Sesudah: Butuh 3x berturut-turut unfocused (total 4.5 detik) sebelum trigger violation

Alasan: HP lambat bisa kehilangan focus sesaat saat transisi halaman

3. Selector Click Handler Diperluas

Sebelum: Hanya a, button, input[type="submit"], .qnbutton, label

Sesudah: Ditambahkan [role="button"], .mod_quiz-next-nav, .submitbtns, .btn, [data-action], .nav-link, .page-link

Alasan: Beberapa element navigasi Moodle (terutama Moodle 4.x) tidak menggunakan tag standar, sehingga grace period panjang (120 detik) tidak aktif

Aplikasi Android (`ExamActivity.kt`)

4. Debounce pada onPause() Violation

Sebelum: onPause() langsung trigger APP_SWITCHING violation

Sesudah: Violation di-delay 3 detik via Handler.postDelayed(). Jika onResume() terpanggil sebelum 3 detik (artinya bukan benar-benar keluar app), violation otomatis dibatalkan

Alasan: Beberapa HP Android (Xiaomi, Samsung low-end, Realme) memicu onPause() saat system dialog muncul atau WebView sedang memproses navigasi berat
