INTRODUCTION… This project is associated with any Android Media Player. The Project is as per the required curriculums of the B.Tech. Android Introduction… • Android is an operating system based on the Linux kernel, and designed primarily for touch screen mobile devices such as Smartphone’s and tablet computers. • Android allows users to customize their home screens with shortcuts to applications and widgets, which allow users to display live content, such as emails and weather information, directly on the home screen. Purpose… Explains the functional features, design… Scope… This application can run anonymously in any Android based Smart-phones, not less than version 2.3.5 Objectives… • Application will be written using Android SDK in Java and should run on all Android OS handsets. • The application will play audio files with format of MP3, AAC, 3GP, M4A, MIDI, RTX, OGG, and WAV. • The application will play video files with format of 3GP, MP4, WEBM. • Background playing options. • Notification on the home screen. • Android is open source and Google releases the code under the Apache License. • Android has a large community of developers writing applications ("apps") that extend the functionality of devices, written primarily in the Java programming language

Main Report

5

• Android is the world's most widely used smart phone platform,[overtaking Symbian in the fourth quarter of 2010. Android is popular with technology companies who require a ready-made, low-cost, customizable and lightweight operating system for high tech devices. • Despite being primarily designed for phones and tablets, it also has been used in televisions, games consoles, digital cameras and other electronics.

Interface of Android…

• The user interface of Android is based on direct manipulation, using touch inputs that loosely correspond to real-world actions, like swiping, tapping, pinching and reverse pinching to manipulate on-screen objects.

6

• Android home screens are typically made up of app icons and widgets; app icons launch the associated app, whereas widgets display live, auto updating content such as the weather forecast, the user's email inbox, or a news ticker directly on the home screen.

Media Player

Introduction…

Media Player is android application that can play various audio and video files. To make use of android OS with more public interest and make it more users friendly so all can use it.

Objectives… • Application will be written using Android SDK in Java and should run on all Android OS handsets. • The application will play audio files with format of MP3, AAC, 3GP, M4A, MIDI, RTX, OGG, and WAV. • The application will play video files with format of 3GP, MP4, WEBM. • Background playing options. • Notification on the home screen. Functional requirements… • Android operating system on the Smartphone. • The target device should be sound enabled. • Ability to play Audio file • Ability to play Video File • Welcome Screen • Main Screen • Player Screen Playlist menu… • Play • Stop • Pause • Songs list • Next • Previous
