A solution for application transplantation from J2ME to Android

Google´s open-source Android mobile platform has been a powerful competitor of mobile operating system and drawn the attention of the leading manufacturers of the industry and became a hot spot of research. As it adopts the virtual machine Dalvik which is different from SUN Java and its Java application developing framework and API are absolutely different from J2EE, a number of mature J2ME applications cannot be applied on Android platform. Thus the general resolution of transplanting J2ME applications onto Android platform not only protects the existing investment but also enriches the applications on Android platform. After analyzing the similarities and differences between Android and J2ME in aspects of virtual machine and UI, this paper discussed the basic approach of transplanting J2ME applications onto Android platform. Due to words limitation, the paper on takes the transplant of J2ME UI child system as example to illustrate an efficient resolution of transplanting J2ME applications.
