摘　　要：在面向对象系统中,一切都表现为对象。通过操作对象提供的方法,实现对象计算资源的引用,这就涉及到了对象数据和操作方法的组织。CAR是一种二进制构件技术,可以动态加载、运行。该文在基于Google的开源工程Dalvik的基础上,结合CAR和Java虚拟机技术,提出了一种Java和CAR混合编程的技术,通过改造Dalvik,使得对象可以是Java和CAR的复合对象,方法是Ja-va或C＋＋方法。通过本文的工作,Android应用的代码保护、运行速度等方面有明显的提升。In the Object-oriented system, all performance Objects. Through methods provided by operated objects, we can use objects compute resources, and it involves the organization of object data and methods. As a binary component technology, CAR can be loaded and reflected dynamically. This paper presents a technology called Java＆CAR mixed programming model, which is base on dalvik, the Google＇s open-source project. Through modifying dalvik, it can create Java and CAR compound objects, with Java or C＋＋ methods. Through this work, we can improve significantly Android application＇s code protection, operating speed and so on.
