Android system process management (basic principle: Manage and automatic release in exchange for low-priority process idle RAM)
When a program into the background, the system may save the data together and let the program sleep, or just run some services only upon receipt of the relevant application to restore the part of the process, end the process after processing while retaining the services - these are handled automatically, that is, if the user is running the software are designed in accordance with Android thoughts, then in addition there is a clear exit key part of the larger programs, other programs are running thrown into the background can no longer manage the , when a program needs more RAM, the system will automatically relieves some of the unimportant and not recently used programs; And when you open a program once opened, the system will first check in RAM is not there this program part of the process, and then be restored, so that it can be quickly opened.
Of course, if the smart phone itself is very small RAM and the CPU is not to force, the system will naturally terminate the process very frequently release memory, which makes many small memory mobile phones it feels a card a card up. So many forums have started to discuss how to make more free memory after all kill, how to disable the automatic start some process - results free RAM really big, but more cards with them - just switch a program (such as reading time came a telephone) system must be restarted almost all related processes, how can slow response.
Android by way of RAM with Windows, Windows Phone, Symbian are two different things. On Android inside, RAM is used full of a good thing. It means that you can quickly open the previously opened software , return to the previous position. So Android very effective use RAM, many users see their RAM is full, they think slow down their phones . In fact, exit and restart these programs really slow down the phone 's response. And these automated the process of killing the software itself is always active in the process, it has always remained active in the background, making the CPU is difficult to break, but increased power consumption.
I think this issue should ultimately blame the programmer. Many domestic Android programmers write programs will not be classified on the process, all processes are always trying to keep in memory (for example, a well-known mobile browser)! which makes these programs even into the background, and it also allowed the system to its release processes. WM, Sybiam system memory management is not so smart, so accustomed to this method is that the programmer and the user put the memory management and usage on Android uses. So here suggested that, for many domestic software , used up or click to exit it, and for the standardization of procedures, and the system comes with those programs (such as Google program basically no exit), after using up the background like.
PS:
1 to develop good software usage, not the exits (left menu to exit, or that the program close button, or will return to the desktop directly right, avoid the middle HOME button!)
