Location in iPhone Web Apps- One of the key limitations of developing Web applications for iPhone is that you are not allowed to access the hardware on the device via the Web browser. For example, you cannot access the camera on the iPhone; neither can you access the accelerometer. This seriously limits the kinds of applications you can develop on the iPhone. One notable exception, however, is the support for tracking the location of devices, through a combination of GPS, Wi-Fi, and cellular triangulation.

Programming Apple Push Notification Services- One of the key limitations of the iPhone is its constraint on running applications in the background. Because of this, applications cannot keep running in the background when the user switches to another application. So, applications that require a constant state of connectivity (such as social networking applications) will not be able to receive timely updates.

Sending SMS with SMPP, Kannel and Java- There are many technologies and protocols that can be used to send and receive SMS from an application. This article focuses on sending SMS via a Short Message Service Center (SMSC), with the help of the Kannel SMS gateway. In order for an application to send a SMS, it generally has to communicate with a Mobile Network Operator (MNO) over the Internet. To understand in more detail consider the following example. A Media service provider wants to send a program timetable as an SMS to its end customers. The application is running on a Linux based java application server.

A Guide to Mobile Emulators- In a previous article, I put forward a three-point plan for testing mobile Web sites. One of the points involved the use of emulators for first-pass device testing. This article concentrates on configuring emulators for mobile site testing (it also highlights emulators that can be used to test mobile applications too). It outlines the different types of emulator available, the best ones to use, and the various ways in which they can be used. For the uninitiated, an emulator is a software program that aims to replicate the functions of a specific piece of hardware or software.

Understanding User Interface in Android - Part 3: More Views- In the previous article, you saw the various basic views such as the TextView, EditText, Button, and how you can use them in your Android applications. In this article, we shall continue our exploration of another three categories of views - Picker views, List views, and Display views. The views discussed include: TimePicker view DatePicker view ListView view Spinner view Gallery view ImageView ImageSwitcher view GridView view

A minimal mobile-aware web app with Python & cloud-based device detection- In this article we'll look at a how to make a minimal device-aware web application. The point of this article is not to demonstrate a useful application but rather to show just how little code is required to make an app that is fully device aware, and that can change its presentation entirely depending on the nature of the device accessing it.

Build Web Apps for iPhone using Dashcode- So far, much mobile developer attention has been fixated on the iPhone SDK released by Apple to build native iPhone applications. This is understandable, since with the SDK you can write native iPhone apps that take full advantage of the capabilities provided by the device, such as accessing the accelerometer, the camera, as well as obtain geographical locations using Core Location.

Getting Started with Java ME- As the world gets connected, we see the emergence of a wide variety of sophisticated and personalized mobile devices. Although the number-crunching power of the higher-end devices is very respectable, there is still a need to build applications that use minimal resources, and that are portable. Java Platform, Micro Edition (Java ME), formerly known as J2ME, with Java’s inherent ‘Build once, run everywhere’ concept has been adapted to build resource constraint applications for these myriad devices.

Understanding User Interface in Android - Part 2: Views- In the previous article on Android UI you saw the components that make up the UI of an Android application. The basic unit of the Android UI is the View. A View represents a widget that has an appearance on the screen. In this article (and the next two), you will learn about the various common views that you would likely use in your journey of Android development. In particular, I have categorized the views in this series into the following group: Basic Views - commonly-used views such as TextView, EditText, and Button views
