Installation method of JAVA application program and terminal device

Abstract

The invention provides an installation method of a JAVA application program and a terminal device, wherein the installation method comprises the following steps: judging whether the JAVA application program is installed or not; if the JAVA application program is installed, copying the duplicate of the installation file of the JAVA application program and modifying the identification value of an application program in the duplicate of the installation file so as to enable the identification value of the application program to be different from the identification value corresponding to the installed JAVA application program; and installing the JAVA application program by utilizing the modified duplicate of the installation file. In the installation method of the JAVA application program provided by the invention, a new application program example can be installed and operated under the condition that the JAVA application program is installed on the terminal device, thereby realizing that multiple application program examples are installed and operated on the same terminal equipment and solving the problem that the multiple application program examples can not be installed or operated on the same equipment in the prior art.

Description

technical field [0001] The present invention relates to communication technology, in particular, to a method for installing a JAVA application program and a terminal device using the method. Background technique [0002] JAVA is a commonly used technology to implement cross-platform applications. It can be used on devices with different operating systems at a very low cost. Therefore, it is widely used in the field of mobile communications, such as mobile communication terminal equipment, such as Mobile phones, personal digital assistants (Personal Digital Assistant, PDA) and car navigation systems, etc. [0003] The JAVA platform is a JAVA language platform provided for terminal devices, and generally consists of a JAVA virtual machine (JAVA Virtual Machine) and a JAVA application programming interface (Application Programming Interface, API). Usually, after the JAVA platform is installed on the operating system of the terminal device, the JAVA application program can run ...

AI Technical Summary

Problems solved by technology

Since the multi-instance requirements of the application were not considered in the early days of the technology, the existing technology cannot install and run multiple application instances on the same device through an installer

[0005] However, with the popularization and application of JAVA technology in mobile terminal equipment, it has become a requirement to install and run multiple application program instances on the terminal equipment through an installation program. For example, in instant messaging service applications, users may wish to have Run and log in multiple accounts, but due to the limitation of the JAVA J2ME specification, the JAVA virtual machine of the prior art cannot realize the above requirements
