Tutorial Membuat Aplikasi Arah Kiblat Sederhana | Tutorial Android

Untuk tutorial kali ini kita akan mencoba membuat aplikasi arah kiblat sederhana untuk android. Yang sebenarnya sudah saya gunakan dibeberapa aplikasi. Tapi untuk yang cuman aplikasi arah kiblat aja kebetulan barusan saya upload ke Google Play, linknya ada disini : Simple Qibla Locator.

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.
