Tutorial Membuat Aplikasi Arah Kiblat Sederhana | Tutorial Android
Bagaimana cara membuatnya? Silahkan ikuti step by step tutorialnya :
1. Buat projek baru dengan nama 'SimpleQiblaLocator' atau terserah teman-teman.
2. Buat kode program pada 'MainActivity.java' dan jangan lupa masukkan background di folder res -> Drawable : bg_kiblat3.png karena kebetulan pada projek ini background-nya saya namain seperti itu di kodingannya.
