The Android SDK gives you all the tools you need to create and test Android applications. It comes in two parts: the base tools, and version-specific SDKs and related add-ons.

The Anatomy of a Mobile Site : Site structure and concepts (part 2) - Entry Points and URLs

When you talk about entry points, you mean the page or URL through which your users enter your site for the first time. A regular desktop website obviously has its home page as the primary entry point, and this is universally located at the root of the domain.

The Anatomy of a Mobile Site : Site structure and concepts (part 1) - Information Architecture

The concept of a site having a "root" (that is, the home page), "child" sections of internally related content, and in turn "grandchildren" pages of individual documents should be familiar enough to most web users.

Using Visual Studio for Windows Phone Development (part 2)

With the Zune software running in the background on your PC, connect your device to the PC and ensure that it is recognized by Windows. Once everything is ready, choose to deploy your application to the device rather than the emulator.

Using Visual Studio for Windows Phone Development (part 1)

Windows Phone devices commonly use organic light emitting diode (OLED) screens for display; they provide a sharp image and are highly responsive to updates, but consume more power when they emit more light.

Windows Phone and .NET : Windows Phone Platform

The huge diversity of hardware could provide quite a barrier for entry for Windows Mobile. Devices all had different screen resolutions, different hardware buttons, and a fairly substantial range of other internal hardware.

Introducing the iPhone SDK (part 5) - Programming Paradigms

iPhone programming centers on two important paradigms: objected-oriented programming and the Model-View-Controller (MVC) design pattern.

Introducing the iPhone SDK (part 4) - iPhone Application Components

Compiled iPhone applications live in application bundles. Like their Macintosh cousins, these application bundles are just folders named with a .app extension.

Introducing the iPhone SDK (part 3) - Assembling iPhone Projects

iPhone Xcode projects contain varied standard and custom components. Project elements include source code, linked frameworks, and media such as image and audio files.

Introducing the iPhone SDK (part 2) - SDK Limitations & Using the Developer Portal

An iPhone development team consists of one or more members. The primary member of the team, called the “agent,” is the original person who enrolled into the iPhone developer program.

Introducing the iPhone SDK (part 1) - Understanding Model Differences & Platform Limitations

Each application is limited to a maximum size of 2GB. To the best of my knowledge, no application has ever come close to this size, and many users complain when applications exceed about 10MB.

iTunes and Your iPad (part 2) - Register Your iPad Without an Apple ID in iTunes & Set Up Your iPad

Your iPad does not have as much memory as your computer, so be careful selecting automatically sync when you have thousands of songs, photos, or many videos in your computer iTunes library.

iTunes and Your iPad (part 1) - Registering or Activating your iPad the First Time

Once you have iTunes installed or updated and running on your computer, you are ready to connect your iPad for the first time and get it registered or activated so you can start using it.

Java ME on Symbian OS : MIDP Graphical User Interfaces API (part 3) - Game API

As the name implies, the LayerManager manages a series of Layer objects. Sprite and TiledLayer both extend Layer. More specifically, a LayerManager controls the rendering of Layer objects.

Java ME on Symbian OS : MIDP Graphical User Interfaces API (part 2) - UIExampleMIDlet

The application also shows how to build a menu using Commands and how to create high- and low-level UI components and switch between them, emulating what we would have in a real-world application.

Java ME on Symbian OS : MIDP Graphical User Interfaces API (part 1)

The LCDUI toolkit is a set of features for the implementation of user interfaces especially for MIDP-based devices. LCDUI is a generic set of UI components split into two categories, high-level and low-level.

Java ME on Symbian OS : Introduction to MIDP & Using MIDlets

A MIDlet is an application that executes under the MIDP. Unlike a desktop Java application, a MIDlet does not have a main method; instead, every such application must extend the javax.microedition.midlet.MIDlet class and provide meaningful implementations for its lifecycle methods.

Developing BlackBerry Tablet Applications with Flex 4.5 : Application Layouts - Blank Application

When creating a Flex Mobile project, you have three choices for your layout: Blank Application, View-Based Application, and Tabbed Application . The selection you make when choosing a layout will determine which files Flash Builder 4.5 will auto-generate.

Developing BlackBerry Tablet Applications with Flex 4.5 : Debug a Flex Mobile Project

The workflow for debugging a Flex Mobile application is the same as debugging any other Adobe Flex or Adobe AIR application.

iPhone Application Development : Implementing File System Storage (part 4) - Implementing Object Archiving & Archiving in the Flash Cards

A running iPhone application has a vast number of objects in memory. These objects are interlinked to one another with references in such a way that if you were to visualize the relationships, they would appear like a tangled spider web.

iPhone Application Development : Implementing File System Storage (part 3) - Implementing the Application Logic

At this point, we’ve defined a flash card model and two complete views, one for creating flash cards and one for using them. All that remains to have a basic flash card application is to implement the two controllers.

iPhone Application Development : Implementing File System Storage (part 2) - Adding a Create Card View Controller

We now have the complete view for using the flash cards, but users also need to be able to create new cards. When users press the Add button in the top toolbar, we’ll show them another view to capture the question and answer for the new flash card.

iPhone Application Development : Implementing File System Storage (part 1)

The application shows the user one card at a time, initially hiding the answer, and then lets users indicate whether they got the answer right. It keeps track of how many times users answer each card right or wrong, and users can create new flash cards and delete existing flash cards.

iPhone Application Development : Understanding the iPhone File System Sandbox

In creating the iOS SDK, Apple introduced a wide range of restrictions designed to protect users from malicious applications harming their devices. The restrictions are collectively known as the application sandbox.

Enterprise Security on the Mobile OS (part 2) - Application Sandboxing, Signing, and Permissions

Mobile devices have become similar to PCs, where it’s almost less about the underlying operating system and more about the applications running on them.

Enterprise Security on the Mobile OS (part 1) - Device Security Options & Encryption

If direct push is enabled, the device will be wiped immediately. If direct push is not enabled, the device will be wiped the next time the mobile device attempts to sync with the Exchange server.

Mobile Geolocation : Geolocation Implementation & Risks of Geolocation Services

On the Symbian platform, signed applications can access the geolocation API without user interaction. For unsigned applications, users will be prompted upon install as to whether they want to grant the application this capability.

Windows Phone 7 : Spicing Up the User Interface with the Silverlight Toolkit (part 3)

The TiltEffect control is demonstrated in the TiltEffectSample.xaml file. Activating the tilt effect on a page is as easy as adding a PhoneApplicationPage attribute. Every control that responds to a tapping gesture will automatically provide the tilt effect animation.

Windows Phone 7 : Spicing Up the User Interface with the Silverlight Toolkit (part 2)

The LongListSelector control is shown in the LongListSelectorSample.xaml file. This page implements the Pivot control you saw in the previous recipe. In the first part of the LongListSelectorSample.xaml code, the resources used to populate the LongListSelector control are defined.

Windows Phone 7 : Spicing Up the User Interface with the Silverlight Toolkit (part 1)

The Microsoft.Phone.Controls.Toolkit.dll assembly that you download from the CodePlex site has 12 controls. Some are new controls, and others are enhanced versions of existing controls.
