Pada Pertemuan Kali Ini saya akan membuat aplikasi Client-Server Pemesanan Lapangan Futsal, Tapi pada blog kali ini saya hanya akan fokus pada Clientnya saja.
Ok, langsung saja ...
- langkah pertama yang harus kita lakukan adalah membuat project baru pada Aplikasi ADT atau sejenisnya .
dengan cara klik pada menu file -> new -> Android Application Project
kemudian kita beri nama disni nama project saya adalah "akta" dengan nama file xml "login".
dengan format project seperti pada gambar di bawah ini:
-login.xml
