Java games on mobile phones

Every mobile phone that supports Java applications actually runs a virtual machine capable of interpreting compiled Java code. The major advantage of using this architecture is the portability of applications; they are not directly dependent on hardware architecture. The disadvantage is given by the hardware used, assuming virtual machine performs many calculations. Roots in key java virtual machine used on mobile platforms, especially on the phone are:
CLDC 1.x
MIDP 1.0
MIDP 2.x
CLDC 1.1
MIDP 3.0
For future they are preparing Mobile 3D Graphics API (M3G), which lets you run games with 3D graphics.

Java virtual machine access to the phone’s basic functions is the various extensions. Of these the most common are:

-File Connection and PIM
-Bluetooth
-Wireless Messaging API (WMA)
-Mobile Media APIÂ (MMAPI)
-Web Services
-Location API
-SIP API
-Mobile 3D Graphics
-Java Technology for the Wireless Industry (JTWI)
-Wireless Messaging 2.0 (WMA)
-Content Handler API
-SVG 1.0
-Payment API
-Advanced Multimedia Supplements
-Mobile Internationalization API
-Java Bindings for the OpenGL ES API
-Mobile Service Architecture
-Mobile Sensor API
-SVG 2.0
Your phone has some features (depending on model and manufacturer) with some of these extensions. Lack of extension makes use applications that can not run correctly. So every time you want to use a java application on your mobile phone make sure the required extensions are present on your device software.

Another key issue in mobile applications is the resolution that the application works. Because less powerful processors and the optimizations made to offer a user experience as good, some applications only work at certain resolutions. Therefore you are unable to start the application, or, in some cases to see only part of the interface. My recommendation is to check this before you decide you want to install a java application.

Device’s performances are also an important consideration for mobile games. The more processing power so there is greater possibility of holding more complex, thus resulting graphics games closer to reality. When choosing a cell phone, consider working and CPU frequency.
