How-To Develop Android Applications
54
by Chris Moor

Ok, so you’ve read the Android FAQ, successfully managed to install the Android SDK and get it up and running, so now you’re finally ready to get building some Android applications.

Below you’ll find anumber of links to sites that will be of great use to you as you get to grips with the Android SDK and begin to work on creating your own applications for the platform.

Android applications are written using the Java programming language, you’ll also use a custom virtual machine (Dalvik) to run and tst your creations. Dalvik is designed for embedded use which runs on top of the Linux kernal.

Below you’ll find a number of links to sites that will be of great use to you as you get to grips with the Android SDK and begin to work on creating your own applications for the platform. Information on how to develop applications, references,in-depth documentation and code snippets can all be found as you work your way through the various guides and tutorials.

An early look at the the Android SDK is also included showing you sample projects , source code, development tools, an emulator and all the libraries you’ll need to build your Android app.
Getting Started With Android

http://code.google.com/android/intro/index.html

This starter module will guide you through everything you need to know about making your first steps into developing for the platform. Talking you through the anatomy of the applications, development tools and getting you started on your first ‘Hello World’ project.
Developing Android Applications

http://code.google.com/android/devel/index.html

Android applications can be developed using the same tools used to develop Java applications. Android’s core libraries will provide you with the functions needed to build high quality rich mobile apps whilst providing you with development tools to make debugging, running and testing your applications much easier.

This module will guide you though the development proces, outlining the core philosphy behind the Android system and going over the key sections in good detail.
Developer Toolbox

http://code.google.com/android/toolbox/index.html

The developer toolbox module will walk you through how to write code that makes the most of the android systems features, allowing you to create custom components and really get to grips with the many API’s at your disposal.
Reference Information

http://code.google.com/android/reference/index.html

As you would imagine this module is made up of a good collection of reference material specificaly related to developing android applications. Details of the application framework and documentationfor the android core libraries are covered in full.
Sample Code

QR code is a great invention people made. I’m making mobile apps currently and find it really cool to implement QR codes into them. I’m amazed at QR code coupons Snappii app builder allows to create. They are really helpful for small businesses.

There are other ways to create apps for Android, better was as I see it. Seattle Clouds and other online services have all the tools one needs to design and fill an app with content without necessity to write a single line of code.

Android devlopment

hi friends,

today im starating my first blog and it is on android devlopment.

Application Fundamentals
Quickview
Android applications are composed of one or more application components (activities, services, content providers, and broadcast receivers)
Each component performs a different role in the overall application behavior, and each one can be activated individually (even by other applications)
The manifest file must declare all components in the application and should also declare all application requirements, such as the minimum version of Android required and any hardware configurations required
Non-code application resources (images, strings, layout files, etc.) should include alternatives for different device configurations (such as different strings for different languages and different layouts for different screen sizes)
In this document
Application Components

The Manifest File

Declaring application requirements
Application Resources

Android applications are written in the Java programming language. The Android SDK tools compile the code—along with any data and resource files—into an Android package, an archive file with an .apk suffix. All the code in a single .apk file is considered to be one application and is the file that Android-powered devices use to install the application.

Once installed on a device, each Android application lives in its own security sandbox:
The Android operating system is a multi-user Linux system in which each application is a different user.
By default, the system assigns each application a unique Linux user ID (the ID is used only by the system and is unknown to the application). The system sets permissions for all the files in an application so that only the user ID assigned to that application can access them.
Each process has its own virtual machine (VM), so an application’s code runs in isolation from other applications.
By default, every application runs in its own Linux process. Android starts the process when any of the application’s components need to be executed, then shuts down the process when it’s no longer needed or when the system must recover memory for other applications.
