Android now has more users, more phones and more tablets worldwide than any other mobile operating system. The Google Play app store has been growing at breakneck speed and with almost as many apps as the Apple app store. This, for entrepreneurs and developers, is the chance of a lifetime to make even more money and reach an even broader audience base. This paper gives a complete knowledge of how to start working on eclipse and develop an application and get it run on emulator. Index Terms- Android SDK, ADT plug-in, AVD manager, Eclipse-IDE, java/c++, Android Apps Development. I. INTRODUCTION ndroid is a Linux-based, open source mobile operating system developed by Open Handset Alliance led by Google to develop apps for Android devices. To start with we use a set of tools that are included in the Android SDK. Once we have downloaded and installed the SDK, we can access these tools right from our Eclipse IDE, through the ADT plug-in, or from the command line. Developing with Eclipse is the preferred method because it can directly invoke the tools that we need while developing applications.. The basic steps for developing applications are shown in Figure 1. The development steps encompass four development phases, which include:  Setup: During this phase we install and set up our development environment. We also create Android Virtual Devices (AVDs) and connect hardware devices, on which we can install our applications.  Development: During this phase we set up and develop our Android project, which contains all of the source code and resource files for our application.  Debugging and Testing: During this phase we build our project into a debug gable .apk package that we can install and run on the emulator.  Publishing: During this phase we configure and build our application for release and distribute our application to users.

ECLIPSE Eclipse is an integrated development environment (IDE). It contains a base workspace and an extensible plug-in system for customizing the environment. Written mostly in Java, Eclipse can be used to develop applications in Java. The initial codebase originated from IBM. The Eclipse software development kit (SDK), which includes the Java development A
