Developing Apps with Eclipse Lesson 7: Lesson 7 completes this course by teaching you how to use Eclipse to develop W2A. You can then learn how to create and run W2A in this environment.
In this part we will acquaint ourselves with the Eclipse software. We will learn more about Eclipse throughout the series, but in this tutorial we will explore the basic features of the Eclipse user interface so that you know your way around before we start developing.
At the time of writing this tutorial, Eclipse is the officially supported IDE for Android, but be aware that this is set to change with the new Android Studio program.
For the moment we just need to create a basic project so that we can use it to become familiar with the Eclipse interface. Also, keep in mind that there is a lot more to Eclipse than what we will cover here.
In this tutorial we will focus on what you need to know to get going in Android. Eclipse models each app you create as a project, with the coding and other resources related to the app stored and managed from within a directory for the project in your workspace.
Creating a new Android project involves a few steps, which we will gloss over at this stage just to get a project setup to show how the Eclipse workspace will look while you are working on an Android app.
Click the "New" button. In the wizard, expand the "Android" folder and select "Android Application Project". This is the process you will use whenever you create a new project for an Android app.
Step 2 In the "New Android Application" screen, you will see various fields you can set. When you click on the text-fields, Eclipse will display some informative text near the bottom of the window. This will automatically be populated in the Project Name field and a package name will also automatically populate.
You can alter these but for the moment leave them with their default contents. You can also leave the SDK options as they stand - these allow you to target particular API levels and to specify the minimum level you wish to support.
As you progress with your Android development skills, you will see that the types of functionality you include will sometimes have implications in terms of which platform levels your app will support.
Of course you want to aim to support as wide a range of devices as possible but this can sometimes be tricky. To continue, click "Next".
The next screen you will see lets you configure the project.
By default Eclipse selects certain settings. Check the options to create a launcher icon for your app, create an Activity for it this is a user interface screenand to create the project in your workspace.
Step 3 Next you will see the Launcher Icon screen. In general you will likely use this to specify a launcher icon image file and to set display properties, but for now just leave it as is and click "Next". In the next screen get Eclipse to generate an Activity for you.
This is likely what you will do for a majority of the apps you create at first. The Activity generated is a single user interface screen, which most apps need at the very least. In the last screen you will see an overview of the project Activity details before it is created.
You can alter the Activity and layout names, but leave them as they are for this tutorial. Click "Finish" to create your project.
Eclipse will create your project, opening the Activity file. But for the moment we will use this basic project to get used to Eclipse. Using Eclipse Views Step 1 Now that we have a project open we can see what Eclipse will look like while you develop your Android apps.
You will see various tabbed areas within the Eclipse window, all of which can be modified to suit your own preferences. These tabbed sections are referred to as views.Most apps are written in Java (you can drop down to using native C), and it’s typical for development to be done within the Eclipse IDE due to the tooling support provided by Google (although.
I want to create apps manually. Using eclipse is the easy way. Using just a text editor is the hard way, but ensure I will know exactly what I'm doing, which is how I like to work.
App for Android INTRODUCTION This tutorial is meant for anyone who has no experience in programming applications for the Android operating system, but would like to.
It is very basic, and installing the necessary programs is more complicated than writing the application itself.
Most apps are written in Java (you can drop down to using native C), and it’s typical for development to be done within the Eclipse IDE due to the tooling support provided by Google (although.
Lesson 7: Develop Apps with Eclipse. Although it’s not too demanding to develop simple Android apps (e.g., Lesson 3’s W2A app) at the command line, you will probably find it tedious to develop.
Mar 07, · I will show you how to setup a working environment using the Android SDK, Eclipse IDE, and ADT Plugin. This Instructable assumes you have knowledge of what Android is and have a basic understanding of programming, although programming is not required.
