Music is the gateway to a soul as well as spiritual and emotional singing. People lose many complexes when they sing aloud, and very often, this opens the barriers between hearts and minds. Even if a voice has no professional technique, singing is still a great experience. Karaoke has brought back to life an old great tradition of singing and therefore today we can not only sing, but also have a wonderful pastime.
Nowadays in Vietnam, a karaoke box is the most popular type of karaoke venue. A karaoke box is a small or medium-sized room containing karaoke equipment rented by the hour or half-hour, providing a more intimate atmosphere. Karaoke venues of this type are often dedicated businesses, some with multiple floors and a variety of amenities including food service, but hotels and business facilities sometimes provide karaoke boxes as well.
Android is a software stack for mobile devices that includes an operating system, middleware and key applications. Google Inc. purchased the initial developer of the software, Android Inc., in 2005. Android's mobile operating system is based on the Linux kernel. Google and other members of the Open Handset Alliance collaborated on Android's development and release. The Android Open Source Project (AOSP) is tasked with the maintenance and further development of Android. The Android operating system is the world's best-selling Smartphone platform. Android has a large community of developers writing applications ("apps") that extend the functionality of the devices. There are currently over 250,000 apps available for Android. Android Market is the online app store run by Google, though apps can be also downloaded from third-party sites. Developers write primarily in the Java language, controlling the device via Google-developed Java libraries. The unveiling of the Android distribution on 5 November 2007 was announced with the founding of the Open Handset Alliance, a consortium of 80 hardware, software, and telecom companies devoted to advancing open standards for mobile devices. Google released most of the Android code under the Apache License, a free software and open source license.
As above, what is the relative between Karaoke and Android? Our teams have seen the relative between them and had something to do with them. It is a software project for our capstone project, an application that named Karaoke Plus (KAPlus) run on mobile. Of course, it related with Karaoke and Android. In this report, we will present overview about our product: What is KAPlus? Why user need and use our application? Moreover, other overview information related with our project also presented.
