What is Android?

Android is an open source and Linux-based Operating System for mobile devices such as smartphones and tablet computers. Android was developed by the Open Handset Alliance, led by Google, and other companies.

Android offers a unified approach to application development for mobile devices which means developers need only develop for Android, and their applications should be able to run on different devices powered by Android.

The first beta version of the Android Software Development Kit (SDK) was released by Google in 2007 where as the first commercial version, Android 1.0, was released in September 2008.

On June 27, 2012, at the Google I/O conference, Google announced the next Android version, 4.1 Jelly Bean. Jelly Bean is an incremental update, with the primary aim of improving the user interface, both in terms of functionality and performance.

The source code for Android is available under free and open source software licenses. Google publishes most of the code under the Apache License version 2.0 and the rest, Linux kernel changes, under the GNU General Public License version 2.

Android menawarkan pendekatan terpadu untuk pengembangan aplikasi untuk perangkat seluler yang berarti pengembang hanya perlu mengembangkan untuk Android, dan aplikasi mereka harus dapat berjalan di berbagai perangkat yang didukung oleh Android.

Versi beta pertama dari Android Software Development Kit (SDK) dirilis oleh Google pada tahun 2007 di mana sebagai versi komersial pertama, Android 1.0, dirilis pada bulan September 2008.

Pada tanggal 27 Juni 2012, pada konferensi Google I/O, Google mengumumkan versi Android berikutnya, 4.1 Jelly Bean. Jelly Bean adalah pembaruan tambahan, dengan tujuan utama untuk meningkatkan antarmuka pengguna, baik dari segi fungsionalitas maupun kinerja.

Kode sumber untuk Android tersedia di bawah lisensi perangkat lunak sumber terbuka dan gratis. Google menerbitkan sebagian besar kode di bawah Lisensi Apache versi 2.0 dan sisanya, kernel Linux berubah, di bawah GNU General Public License versi 2.

Android Applications

Android applications are usually developed in the Java language using the Android Software Development Kit.

Once developed, Android applications can be packaged easily and sold out either through a store such as Google Play, SlideME, Opera Mobile Store, Mobango, F-droid and the Amazon Appstore.

Android powers hundreds of millions of mobile devices in more than 190 countries around the world. It's the largest installed base of any mobile platform and growing fast. Every day more than 1 million new Android devices are activated worldwide.

This tutorial has been written with an aim to teach you how to develop and package Android application. We will start from environment setup for Android application programming and then drill down to look into various aspects of Android applications.


Aplikasi Android biasanya dikembangkan dalam bahasa Java menggunakan Android Software Development Kit.

Setelah dikembangkan, aplikasi Android dapat dikemas dengan mudah dan terjual habis baik melalui toko seperti Google Play, SlideME, Opera Mobile Store, Mobango, F-droid dan Amazon Appstore.

Android mendukung ratusan juta perangkat seluler di lebih dari 190 negara di seluruh dunia. Ini adalah basis terpasang terbesar dari semua platform seluler dan berkembang pesat. Setiap hari lebih dari 1 juta perangkat Android baru diaktifkan di seluruh dunia.
