Mobile application development
||This article may contain promotional material and other spam. (September 2012)|
iOS, Android, BlackBerry, webOS, Symbian OS, Tizen, Ubuntu Touch, and Windows Mobile support typical application binaries as found on personal computers with code which executes in the native machine format of the processor (the ARM architecture is a dominant design used on many current models). Windows Mobile and Ubuntu Touch can also be compiled to x86 executables for debugging on a PC without a processor emulator. Windows Mobile also supports the Portable Executable (PE) format associated with the .NET Framework. Windows Mobile, Android, HP webOS, iOS, Firefox OS and Ubuntu Touch offer free SDKs and integrated development environments to developers.
Platform development environment
Each of the platforms for mobile applications also has an integrated development environment, which provides tools to allow a developer to write, test and deploy applications into the target platform environment.

Criteria for selecting a development platform usually contains the target mobile platforms, existing infrastructure and development skills. When targeting more than one platform with cross-platform development it is also important to consider the impact of the tool on the user experience. Performance is another important criteria, as research on mobile applications indicates a strong correlation between application performance and user satisfaction.
Mobile application testing
Mobile applications are first tested within the development environment using emulators and later subjected to field testing. Emulators provide an inexpensive way to test applications on mobile phones to which developers may not have physical access. The following are examples of tools used for testing application across the most popular mobile operating systems.
- Google Android Emulator
It is Android Emulator which is patched to run on a Windows PC as a standalone app without having to download and install the complete and complex Android SDK. It can be installed and Android compatible apps can be tested on it.
- Official Android SDK Emulator
It includes a mobile device emulator which mimics all of the hardware and software features of a typical mobile device (without the calls).
- eggPlant for mobile testing:eggPlant delivers a robotic solution to mobile testing across all operating systems and devices.
MobiOne Developer is a mobile Web IDE for Windows that helps developers to code, test, debug, package and deploy mobile Web applications to devices such as iPhone, BlackBerry, Android, and the Palm Pre.
It gives a pixel-accurate web browsing environment and it is powered by Safari. It can be used while developing web sites for the iPhone. It is not an iPhone simulator but instead is designed for web developers who want to create 320 by 480 (or 480 by 320) websites for use with iPhone.iPhoney will only run on Mac OS X 10.4.7 or later.
- BlackBerry Simulator
There are a variety of official BlackBerry simulators available to emulate the functionality of actual BlackBerry products and test how the BlackBerry device software, screen, keyboard and trackwheel will work with application.
- ZAP-fiX for Mobile Application Testing:ZAP-fiX delivers a universal solution to mobile application testing across all operating systems and devices.
- SeeTest from Experitest supports all the major mobile platforms (iOS, Android and Blackberry). It enable element identification using Native / Image and Text recognition. And it comes with integration into platforms like QTP, MSTest, Java/JUnit, Python and Perl.
- Ranorex for Mobile App Test Automation supports object-based test automation of Android, iOS and Windows 8 Apps.
- AppgyverToolbelt: Tooling to develop and iterate apps for PhoneGap across the two major smartphone platforms – Android and iOS – with no requirement for Xcode.
- eggPlant: A GUI-based automated test tool for mobile application across all operating systems and devices.
- Sikuli: This is a visual technology to automate and test graphical user interfaces (GUI) using images.
- Ranorex: Test automation tools for mobile, web and desktop apps.
Several initiatives exist both from mobile vendor and mobile operators around the world. Application developers can propose and publish their applications on the stores, being rewarded by a revenue sharing of the selling price. An example is Apple's App Store, where only approved applications may be distributed and run on iOS devices (otherwise known as a walled garden). There are approximately 7,000,000 iOS Applications. Google's Android Market (now known as the "Play Store") has a large number of apps running on devices with Android OS. HP / Palm, Inc have also created the Palm App Catalog where HP / Palm, Inc webOS device users can download applications directly from the device or send a link to the application via a web distribution method. Mobile operators such as Telefonica Group and Telecom Italia have launched cross-platform application stores for their subscribers. Additionally, mobile phone manufacturers such as Nokia has launched Ovi app store for Nokia smartphones. Some independent companies, namely Amazon Appstore, Aptoide and GetJar, have created their own third-party platforms to reach more users in different locations. The Windows Phone Marketplace had more than 100,000+ apps available as of 7-11-2012 .
There are many patents applications pending for new mobile phone apps. Most of these are in the technological fields of Business methods, Database management, Data transfer and Operator interface.
On May 31, 2011, Lodsys asserted two of its four patents: U.S. Patent No. 7,620,565 ("the '565 patent") on a "customer-based design module" and U.S. Patent No. 7,222,078 ("the '078 patent") on "Methods and Systems for Gathering Information from Units of a Commodity Across a Network." against the following application developers:
