Android Views (part 2) - Button and ImageButton
The AdapterView is a generic, list-oriented view of data. Any collection of data objects that can be ordered in some relatively stable way can be displayed through an AdapterView.
Android Views (part 1) - TextView and EditText
Example 1 shows how to use a TextView and an EditText with Buttons. It also shows the XML layout file (main.xml), which uses pretty standard and recommended layout parameters.
Java ME on Symbian OS : Networking and General Connection Framework (part 2) - Security Policy for Network Connections & NetworkDemo MIDlet
On the Nokia N95, for example, an untrusted MIDlet can access the Net Access function group with User permission (explicit confirmation required from the user).
Java ME on Symbian OS : Networking and General Connection Framework (part 1)
Symbian's MIDP implementation includes support for sending and receiving UDP datagrams. A datagram connection can be opened in client or server mode. Client mode is for sending datagrams to a remote device.
jQuery 1.3 : Effects - Basic hide and show
The basic .hide() and .show() methods, without any parameters, can be thought of as smart shorthand methods for .css('display','string'), where'string' is the appropriate display value.
jQuery 1.3 : Effects - Inline CSS modification
This method acts as both a getter and a setter. To get the value of a style property, we simply pass the name of the property as a string, like .css('backgroundColor'). Multi-word properties can be interpreted by jQuery when hyphenated, as they are in CSS notation, or camel-cased, as they are in DOM notation.
Mobile Web Apps : Events
The DOM click event comprises two separate steps: a mousedown, followed by a mouseup. Evidently, it’s an event designed for a mouse, where clicking takes just a fraction of a second, and is done after the user has moved the mouse into the correct position.
Mobile Web Apps : Setting up Shop
As a first pass for app-ifying our mobile website, we’ll set up our environment, hook up a couple of common DOM events, and use the native-like features gifted to us for some gratifying “quick wins.” These should help us get well on the way to creating a usable app that we can build on with more advanced features.
iPhone 3D Programming : Simplify with glDrawTexOES
Recall that updating the VBO at every frame and computing texture coordinates was a bit of a pain; it turns out the iPhone supports an easier way to render pixel rectangles when you’re using OpenGL ES 1.1.
iOS SDK : Adding a SQLite Database
Adding binary data using SQLite Manager in Firefox seems to be buggy. Sometimes it works, sometimes not. If after adding a record the photo column is blank, just edit the row and add the photo file’s content again.
The Anatomy of a Mobile Site : Navigation and menu systems (part 3) - Paving Mobile Pathways & Switcher Links
The process of modeling your site to suit user behavior is, naturally, a very inexact science, and one that you can do only with a deep understanding of the business or project priorities for the site and the likely behaviors of your target users
The Anatomy of a Mobile Site : Navigation and menu systems (part 2) - Breadcrumbs, Header and Footer Navigation
Breadcrumbs work well and are easiest to implement when a site is organized into a strict, single-dimensional hierarchy. A challenge arises if the page can be reached by multiple routes through the site, and the breadcrumb logic needs to decide which ancestral path through the hierarchy or hierarchies it should display.
The Anatomy of a Mobile Site : Navigation and menu systems (part 1) - Navigational Lists & Decorating Menus
If you are going to use full-width navigation elements, then there may be plenty of room to decorate the links themselves. Unless the text of the link is very long, there should be space both left and right of the link to help the user understand the behavior or purpose of the link.
iPad Troubleshooting : No Sound in Music or Video
There are few things more frustrating than hoping to listen to music or watch a video, only to find that no sound comes out of the iPad.
iPad Troubleshooting : How to Hard-Reset Your iPad & How to Soft-Reset Your iPad
Resetting your iPad is your last response to an unresponsive iPad. It is perfectly safe, and it usually fixes many problems.
iPad : 3G Cellular Data Connection
If you have a 3G iPad, you will also be able to connect to the cellular data network – the same network you connect to with an iPhone or other mobile phone.
Beginning Android 3 : Set Up the Device
With an emulator set up, you do not need an Android device to get started in Android application development.
Beginning Android 3 : Set Up the Emulator
The Android emulator can emulate one or several Android devices. Each configuration you want is stored in an Android Virtual Device (AVD).
Getting Started with XNA : Your First XNA Project (part 3) - Examining the Solution in More Detail
Something else that may have been unexpected when you created the XNA project is the presence of the Content project. This project, which is initially empty, has the sole purpose of containing all the external data files (graphics, sound files, 3D models and so on) that you wish to use within your game.
Getting Started with XNA : Your First XNA Project (part 2) - Moving the Graphic
When coordinates are written down, they are enclosed within parentheses inside which the two values are placed, separated by a comma. The first value is the x coordinate, and the second is the y coordinate.
Getting Started with XNA : Your First XNA Project (part 1)
With our graphic in place, we can now amend the code to display it on the screen. This is very simple and consists only of modifications to Game1.cs, so ensure that it is open in the code editor.
iPhone : Working with View Controllers - Building a Simple Two-Item Menu & Adding a Segmented Control
The following recipes introduce these core navigation controller features, from building menus to building a history stack. In these examples, you see how to use the UINavigationController class to create a variety of novel and useful interfaces.
iPhone : Working with View Controllers - Developing with Navigation Controllers & Utility Function
The following recipes introduce these core navigation controller features, from building menus to building a history stack. In these examples, you see how to use the UINavigationController class to create a variety of novel and useful interfaces.
Fundamentals of Java ME MIDP Programming : MIDP Security Model (part 3) - The Security Model in Practice
To sign a MIDlet suite, the supplier of the suite needs to obtain a public-private key pair either by generating a new key pair or importing an existing key pair.
Fundamentals of Java ME MIDP Programming : MIDP Security Model (part 2)
An MIDP device must support at least one protection domain, the untrusted domain, and may support several protection domains, although a given MIDlet suite can only be bound to one protection domain.
Fundamentals of Java ME MIDP Programming : MIDP Security Model (part 1) - The X.509 PKI & Certification Paths
An MIDP device must support at least one protection domain, the untrusted domain, and may support several protection domains, although a given MIDlet suite can only be bound to one protection domain.
Fundamentals of Java ME MIDP Programming : Non-GUI APIs in MIDP
MIDP provides a simple record-based persistent storage mechanism known as the Record Management System (RMS). It's a package that allows the MIDlet application to store persistent data within a controlled environment, while maintaining system security.
iPad : Advanced Wi-Fi Options (Hidden or Undiscoverable Networks)
The nice thing about the iPad is that when you return to an area with a Wi-Fi network you previously joined (whether it was an open or a secure, password-protected, network) your iPad will automatically join the network without asking you again.
iPad : Wi-Fi Connections
Every iPad comes with Wi-Fi capability built in. If you have a 3G model (you can tell it's 3G because there is a black plastic strip along the top edge), then you have both 3G and Wi-Fi
Beginning Android 3 : Install the ADT for Eclipse & Install Apache Ant
If you will not be using Eclipse for your Android development, you can skip to the next section. If you will be using Eclipse but have not yet installed it, you will need to do that first
