Application package installation method and system applied to resource-constrained device

The invention relates to an application package installation method and system applied to a resource-constrained device. The invention provides a technology for realizing an object-oriented virtual machine in a resource-constrained device, which is used for specially designing instructions of an instruction centralized access class, a static domain, a static method, an instance domain and a virtual method aiming at a resource-constrained hardware environment, and can be used for removing a constant pool index adopted by an existing instruction. Complex analysis processing is needed during class installation; the design of the static domain initial method can replace the existing static domain component technology, and the initialization operation of the static domain is simplified; through the optimization steps, the effects of reducing the file size of the installation package and improving the installation speed of the installation package are achieved. 本发明涉及一种应用于资源受限装置的应用包安装方法和系统。本发明提出一种在资源受限装置实现面向对象的虚拟机的技
