DOKUMENTASI TUGAS

PENDAHULUAN

Pada pertemuan ke 6, penulis diajarkan materi mengenai "Studi Kasus - Membuat Halaman Login". Halaman login digunakan untuk tujuan otentikasi dalam aplikasi. Penulis membutuhkan halaman login pertama di mana pengguna akan dapat masuk lebih lanjut menggunakan nama pengguna dan kata sandi. Dalam tugas ini, penulis telah membuat halaman login sederhana di studio android di mana tujuan otentikasi statis, yang berarti nama pengguna dan kata sandi sudah akan ditetapkan dalam kode. 
Setelah diajarkan materi penulis diberikan tugas untuk membuat aplikasi LoginPage/LoginForm sederhana. Untuk implementasi tugas ada di bawah ini.
