What if the background program of Android phone can't be closed?
The problem that the Android background can't be closed is actually entirely due to the broadcast mechanism of Android. Simply put, when a user installs a program, the system will record the functions of the program like an interviewer. When the user uses the mobile phone, the change of system state will produce various events. When these events need some programs to handle, the system will send a broadcast message, and these programs that can handle this matter will be enabled. Which program should I use to handle this event? This is the default program of the system or the program selected by the user.
For example, if you start a company, Android is your housekeeper, and those programs are the employees who come here to apply. The housekeeper will record the abilities of these employees, such as A taking a bath and B being very attentive. When you want to take a bath, the housekeeper will ask A to help you take a bath. When you want a big health care, the housekeeper will ask B to give you a big health care. Even if this program is dormant, it will be called. That is to say, no matter how you close these applications, it is just a screw when you need it, where you need it.
Of course, some programs you don't need have started themselves. This is because of interests. Many rogue software in China have changed the priority of their own programs, increased the authority to terminate other programs, and increased the function of the daemon. When it is detected that one of our own people has been killed, a resurrection will directly resurrect this program with blood blue. Other social software is to ensure that messages can be pushed in time and will make some priority changes.
If the running memory is large, is it unnecessary to turn it off?
In fact, the idea of Android system design is to dilute the user's management of the background, and the allocation of mobile phone resources can be completely handed over to the system. Android will set a threshold, and the default setting is very small, so the amount of memory we see will be very small, which will not actually affect the speed of the mobile phone. In addition, it has its own rules to retrieve these memories. When the memory usage reaches the critical value, opening another program system again will select some less important programs to close, making room for the operation of this program.
The reason why we feel that it will be slow to open a big program on a mobile phone is because when you open this program, this program will apply for memory from the system. Because the system will not shut down all processes, it will only shut down selectively, so it will mobilize a lot of system resources to run, which will naturally slow down the system. Changing the system threshold will improve a lot, but it may also bring some problems.
So the background program itself does not need to be closed. If you can manually close a large program, you can significantly improve the speed, and you don't need to care when you use it normally. As for the size of memory, unless your memory is large enough, the N+ app will reach this threshold sooner or later.
Close the background running program of the mobile phone.
Method 1: Exit the program on the application.
Now many software games will not continue to run in the background after they quit. For this kind of application, we only need to click the "Back button" twice on the application interface to exit, or click Exit at the application settings.
Method 2: Close the program in the phone settings.
If the mobile phone application will still run after closing the foreground, you can also close the application in the mobile phone settings.
1. Find "Application" in the phone "Settings" and find the application in the application list, as shown below.
2. Click the application icon to open the settings page, and then click "Force Stop".
Method 3: Close the program with third-party software.
Now many mobile phone management softwares have the function of closing programs, such as 360 Mobile Guardian, Tencent Mobile Manager and Advanced Task Manager. Here, take 360 mobile guards as an example to explain to you.
1. Open 360 Mobile Guard, find "Memory Cleanup" in "Mobile Acceleration" and click, as shown below.
2. Select the application process to clean up on the "Memory Cleaning" page. Some commonly used softwares such as Baidu input method can be cleaned without cleaning, and then select "one-click cleaning", as shown below.
3. In addition, after the installation of 360 Mobile Guardian, there will be a small icon on the screen of the mobile phone to show the percentage of memory, as shown in the following figure. Click to open a small window, and click one to close the application. You can also click "Clean with One Click" to close all foreground applications.
Some small software in the mobile phone takes up very little memory, so users don't need to close the background program if they use it frequently, which will speed up the time for you to start the software next time and increase the user experience. For software games that occupy a lot of memory, we can manually close them to ensure the progress of the system and save the power of the mobile phone.
