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
and more is not the problem, such as the latest out of electricity A10 have 1 GHz main frequency, memory capacity, up to 1 GB, and apple iPad2 still only 512 MB memory, although iOS efficiency is higher, but through the simple add memory, electricity A10 such flat after iPad2 won't use experience, and at the same time or have stable operation, not easily andros program collapse advantages.From the test scores at with 1 GB of memory electricity in memory performance A10 is very leading, but this is just the test software test scores, in actual start, Internet, open applications, games and applications of the time, you can obviously feel 1 GB of memory electricity than the 512 MB of memory A10 similar flat to smooth a lot.
We know, using the apple iOS system iPad2 equipped with 512 MB memory, and operating system with the virtual machine andros + Java language structure, virtual confidential takes up part of the memory space, memory footprint is Java language than apple's C language is to high, and the real multitasking andros system memory requirement system to higher, so the same 512 MB memory android tablet operation efficiency and user experience sure can't and iPad2 ratio, but the 1 GB memory after, through the leading hardware, can be considerably reduced and iPad2 performance gap between experience, so I think 1 GB of memory android system, it is very should popularity of a configuration, and electricity in this respect in the A10 walk the front. Because of the low price memory, now one thousand yuan level andros flat, should at least equipped with 1 GB of DDR3 memory above, it is more reasonable configuration.
