­obviously, this is not an advertisement!

­it simply doesn't make sense not to share such a good app with the tails, so I decided to write a brief introduction to "black domain" myself.

So before we talk about "black domain", let's talk about the embarrassment of domestic Android applications. Note that the following information is not necessarily accurate.

As we all know, Google services are interfered by XX in China, and many services of Android system will become incomplete without these support. For example, push service, Android and iOS have the same system-level push service, this service is called Google Cloud Messaging, now the new name is Firebase Cloud Messaging.

­due to the interference of this service, if domestic Android apps want to push messages to users, they usually choose third-party push services such as "Xiaomi push", "aurora push" and "one push". In order to ensure the reliability of the service, they have to keep the application running rather than completely clear it from the background task.

Then the problem arises.

In order to ensure the fluency and stability of mobile phones, the major domestic mobile phone manufacturers will choose to let the system kill those application processes that are resident in the background. As the system functions of different mobile phone manufacturers are completely different, the methods of killing processes are all different. For example, Android apps with Xiaomi push service can get the highest message delivery rate under MIUI, even if the app is cut to the background, it can still receive notifications under normal circumstances. But if it's on Flyme OS, when the app goes to the background, it's likely that its process will be killed, making it impossible for messages to be delivered properly.

Some domestic applications of ­▲ that people love and hate.

To this end, these Android applications have to take some measures to ensure that push notifications from their own applications can be delivered to users, so …... Thump, thump! Let's have a round of applause for the "whole family bucket"! And then.

­A push notification directly wakes up multiple applications at the same time, the power in the background drops, the fuselage is hot, and sliding stutters. Oh, my God, this is a disaster. If the mobile phone manufacturers do not deal with this situation, the final result can be imagined.

Of course, don't think that these domestic apps need to be resident in the background just for push, such as automatically downloading and installing packages, because the Google Play store does not enter China, and applications cannot be updated automatically. In order to ensure that users use the latest version of the application, resident backstage automatically download installation packages and so on, hehe.

This is the current situation of Android without Google service in China. It appears to have Chinese characteristics, but in essence, it is caused by a congenital defect. Yes, this defect cannot be changed by relying solely on science to surf the Internet.

­at this point, some non-Android users may feel that iOS is superior again. In fact, Google has realized this phenomenon, which is why from Android N to Android O, Google has begun to specifically address these phenomena. Not long ago, "Green Guardian" developer Oasis Feng also launched the "Android Green Application Convention", our "digital tail" client for Android will also join, please look forward to it!

­so, for those non-domestic mobile phones, or Android phones that do not specifically deal with this domestic phenomenon, how to treat the annoyance of the "family bucket"? I think most people have heard of the "green daemon" and the "stop running" of the Xpose framework. Of course, it's okay if you haven't heard of it, but now you know!

However, the "black domain" introduced this time is the successor of "blocking operation". Compared with its predecessor, the "black domain" no longer needs Root permission, as long as it is connected to the computer and run the ADB command to start the black domain, which is the best choice for non-Root phones to specialize in "family buckets"!

­according to the introduction of "black domain" in Google Play, we can get a general idea of how it works:

­after getting tired of constantly ROOT / unlocking, develop a black domain, standby (App Standby, Android 6.0 is introduced, but not every machine supports it) or forcibly stop the application to prevent the program from running continuously. Black domains do not require ROOT, nor do they need to change the system. At present, there is also a ROOT mode, but it is very experimental and can only solve the problem of no computer startup.

­the black domain uses event intelligence to determine whether you are using an application. When you open an application and exit (such as pressing "back"), the black domain will standby it; when the standby timeout occurs, or cross it off from the most recent list, the black domain will forcibly stop it. For any wake-up call that does not have an open interface, it will be forcibly stopped as long as you have not opened it. At the same time, you can also set "allow synchronization" for applications, which have irrevocable notifications or do not process it when there is a foreground service, or wait for it at most when there is a notification or when it is running in the background.

­Black domains support Android 5.0to O Beta, which does not require ROOT or unlock, but relies on "USB debugging" in developer options. I mainly use it on Google Pixel.

­it's amazing, so how do you use it?

­the method is simple, and there is no need to create a messy JDK environment. The detailed process is as follows:

­1. Prepare a Windows PC and click here to download the ADB tool

­2. Extract the ADB tool package and place it in a directory other than the Chinese path, preferably the root directory of the disk.

­3. Enter the developer option and open the phone USB for debugging.

­4. Connect the mobile phone to PC and switch to MTP transmission mode.

­5. Make sure that the phone and PC are connected properly, and open Command Prompt in the ADB folder.

­6. Enter the following command:

­adb-d shell sh / sdcard/Android/data/me.piebridge.brevent/brevent.sh

­▲ copy and paste command

­▲ command has been executed and finished.

­after completing the above command, you can enjoy the changes brought about by the "black field"! However, it should be noted that once the phone restarts the "black domain" effect will be invalid, so it is not recommended to restart the phone casually.

­more tutorials on the use of "black domain" will not be explained in depth in this article. The author of "black domain" has written a very detailed official tutorial, which can be viewed here if you are interested.
