Andriw Nuliskuy: UAS Mobile Programing

Deskripsi Project :

Membuat aplikasi dengan listview :
- Masukan username dan password klik login untuk masuk ke form listview, klik form toko untuk masuk ke form toko, pilih salah satu produk otomatis akan keluar price masukan qty klik hitung untuk total, Untuk volume bola masukan angka jari jari lalu klik hasil. Dan di form konversi decimal to octal, masukan jumlah decimal dan klik convert otomatis dikolom octal akan terisi.

Terdapat beberapa form, yaitu :
A. Form Login
B. Menu ListView
C. Form Toko
D. Volume Bola
E. Konversi Decimal To Octal

Tugas UAS mata kuliah Mobile Programing, yaitu membuat sebuah program Android dengan menggunakan Aplikasi Android Studio. Untuk mengetes aplikasi disini saya menggunakan Handphone Android saya "Realme 3 PRO" tentunya dengan mengaktifkan USB Debugging pada Opsi Pengembang terlebih dahulu.
