Interlayer device used for J2ME(Java 2 Micro Edition) application program development, and application method thereof

Abstract

The invention provides an interlayer device used for J2ME(Java 2 Micro Edition) application program development, which is arranged between a J2ME application program and a J2ME running platform of a mobile telephone. The interlayer device comprises an interface control module, a logic setting module, a keystroke processing module and a screen processing module, wherein the interface control module is used for providing an interface control for drawing every interface required by the J2ME application program; the logic setting module is used for setting response logic of all kinds of keys for every interface; the keystroke processing module is used for selecting key assignments corresponding to the current mobile telephone when keystroke touch occurs, thereby triggering the response logic of every interface; and the screen processing module is used for selecting a screen size corresponding to the current mobile telephone, thereby displaying every interface when the J2ME program is run on the J2ME running platform. The invention also provides a method using the device. The interlayer device used for J2ME application program development and the application method thereof provided by the technical scheme of the invention can maximally compromise the differences between mobile telephone platforms and the edition difference between CLDC(Connected Limited Device Configuration) and MIDP(Mobile Information Device Profile), and can overcome the problems encountered in the development process of the J2ME application program in the prior art.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an intermediate layer device and an application method for J2ME (Java 2 Micro Edition, Java 2 Micro Edition) application program development. Background technique [0002] J2ME, also known as Kjava, is a programming language that can be used for handheld devices. It is usually used in embedded devices and consumer appliances, such as mobile phones, PDAs, smart cards, and TV set-top boxes. The mobile phones described in the present invention are all mobile phones supporting J2ME application programs. Compared with J2SE (Java 2 Standard Edition) and J2EE (Java 2 Enterprise Edition), J2ME has a more diverse operating environment and goals overall, but each product is more single-purpose and has stricter resource constraints. In order to meet the needs of different aspects while achieving standardization and compatibility, the architecture of J2ME is divided into Conf...

AI Technical Summary

Problems solved by technology

These platform differences need to be dealt with separately, which brings greater difficulty and more workload to the cross-platform transplantation of J2ME software.

[0010] 2. Version difference between CLDC and MIDP

[0014] To sum up, it can be seen that for the application programs developed on the current J2ME platform, the mobile phones in the prior art cannot run indiscriminately, but can only be limited by the mobile phone model when the application program is developed.
