Google has JAVA is a very mature, very popular programming language, programming threshold is very low, it is easy to learn, to run the program will also very stable. But bringing the shortcomings of are obviously: Java applications written program is more eat memory, because be in the virtual machine operation, rather than run directly, so speed will slowly. The performance in the early days of the android system, particularly evident, especially running game, many in the apple iOS running on a good game, transplanted to android system simply run motionless, or very slowly.
Relatively speaking, apple's ios system using C is the department of Objective-C programming language mainly, the compiled application directly on the equipment operation, the efficiency is very high. But apple's cisco iOS architecture and disadvantages, programming is difficult, and application processing bad is easy to flash back, not virtual memory, many applications that didn't happen. And the problem of andros system, along with the development of hardware in a day, more
