Mobile software is intended to run on handheld PC’s, personal digital assistants (PDAs), smartphones and mobilephones. Since 1980s, the popularity of these platforms has risen considerably. Recent model mobile phones have included the ability to run user-installed software.And as therefore there are so many platforms for mobile phones. Platform means the softwares on which the mobile device is working.

Main Mobile Platforms

Windows Mobile, Palm OS and Symbian OS  are the most common mobile platforms.Windows Mobile also supports the Portable Executable (PE) format associated with the .NET Framework. Both Windows Mobile and Palm OS offer free SDKs and Integrated Development Environments to developers. Machine language executables offer considerable performance advantages over Java. Also most of the mobiles can run java.

Java (in its incarnation as “J2ME” / “Java ME” / “Java 2 Micro Edition”) runs atop a Virtual Machine (called the KVM) which allows reasonable, but not complete, access to the functionality of the underlying phone. This extra layer of software provides a solid barrier of protection which seeks to limit damage from erroneous or malicious software. It also allows Java software to move freely between different types of phone (and other mobile device) containing radically diverse electronic components, without modification. The price that is paid is a modest decrease in the potential speed of the game and the inability to utilized the entire functionality of a phone (as Java software can only do what this middle-man layer supports.)Because of this extra security and compatibility, it is usually a quite simple process to write and distribute Java mobile applications (including games) to a wide series of phones.
