Description

TECHNICAL FIELD

[0001] The application belongs to the field of data processing, and particularly relates to a multi-process foreground and background detection method based on an Android system. BACKGROUND

[0002] In the prior art, an ActivityManager is often used to obtain a running process list, and then it is judged whether a process package name is running in the foreground. This method cannot meet privacy compliance because it needs to scan all processes in the system, and it cannot perfectly detect the foreground and background when there are multiple processes, for example, when an application has multiple processes, the method can only detect whether the application is in the foreground, but cannot detect whether an individual process is in the foreground. SUMMARY

[0011] In a possible implementation, the page count of the process is initialized as 0;

[0012] When the display page count object onActivityStarted collects the cumulative value of the display page count of the process, the count value of the page count is added to the cumulative value of the display page count to obtain a first addition result, and the first addition result is taken as a new page count;

[0013] When the hidden page count object onActivityStopped collects the cumulative value of the hidden page count of the process, the count value of the page count is added to the cumulative value of the hidden page count to obtain a second addition result, and the second addition result is taken as a new page count.

[0014] In a possible implementation, when the process is created, the process is bound to the remote service Service, including:

[0015] When the process is created, the communication between the process and the remote service Service is established, and the corresponding display page count object onActivityStarted, the hidden page count object onActivityStopped and the page count of the process are created through the remote service Service, so as to complete the binding of the process to the remote service Service.

[0038] In order to make the purpose, technical solutions and advantages of the present application more clear and obvious, the present application will be further described in detail below in combination with the embodiments and drawings, and the exemplary embodiments of the present application and their descriptions are only used to explain the present application, and not as a limitation on the present application.

[0039] Embodiment 1

[0040] As shown in the Figure 1 application provides a multi-process foreground and background detection method based on an Android system, which is used for detecting the foreground and background of processes in the Android system, and includes:

[0041] S11, a remote service Service is created, and the remote service Service is used to collect the page count of a process.

[0042] The remote service Service is essentially a resident process that has been running, and the remote service Service is used to collect the page notification of the process or the sub-process corresponding to other APPs, so as to realize the collection of the page count of the process. For example, the display page count cumulative value and the hidden page count cumulative value of the process can be collected through the remote service Service, and then the page count is obtained according to the display page count cumulative value and the hidden page count cumulative value, so as to obtain the count data of the foreground and background detection.

[0043] S12, when the process is created, the process is bound to the remote service Service, and each process has a corresponding page count in the remote service Service.

[0044] The process can be bound to the remote service Service by establishing the communication between the remote service Service and the process, so that the remote service Service can collect the display page count cumulative value and the hidden page count cumulative value of the process. For example, the aidl file IForegroundDetectService.aidl of the foreground and background detection can be created, and the aidl file includes the display page count object onActivityStarted and the hidden page count object onActivityStopped.

[0045] The display page count object onActivityStarted can collect the display page count cumulative value of the current process without sending the notification, and the hidden page count object onActivityStopped can collect the hidden page count cumulative value of the current process without sending the notification.

[0046] S13, the display page count cumulative value and the hidden page count cumulative value of the process are synchronized to the page count of the remote service Service, and the foreground and background detection of each process is performed according to the page count, so as to complete the foreground and background detection of the multiple processes.

[0047] The multiple process foreground and background detection method based on the Android system provided by the embodiment of the application realizes the foreground and background detection of the multiple processes by constructing the remote service specially detecting the foreground and background of the process, and configuring the corresponding page count for each process, and detecting the foreground and background of the process according to the page technology, and does not need to scan all the processes and does not need to apply for the permission, so as to avoid the problem that the system cannot be detected due to the unopened permission, and meet the privacy compliance.

[0048] In a possible implementation, the remote service Service is created, including: creating the remote service Service including a display page count object onActivityStarted and a hidden page count object onActivityStopped, the display page count object onActivityStarted is used to collect the cumulative value of the display page number of the process, and the hidden page count object onActivityStopped is used to collect the cumulative value of the hidden page number of the process.

[0049] In a possible implementation, the page count of the process is initialized to 0; after the display page count object onActivityStarted collects the cumulative value of the display page number of the process, the count value of the page count is added to the cumulative value of the display page number to obtain a first addition result, and the first addition result is taken as a new page count; after the hidden page count object onActivityStopped collects the cumulative value of the hidden page number of the process, the count value of the page count is added to the cumulative value of the hidden page number to obtain a second addition result, and the second addition result is taken as a new page count.

[0050] The ForegroundDetectService is created to inherit the remote service Service of the system, and a page count count is maintained in the service to collect the total number of the currently displayed pages of each process. Then, an internal class is created to implement the Stub class produced by the system, and the display page count object onActivityStarted is implemented, that is, the page display number c1 called by each process needs to be updated, the current page count count is 0, and the callback is entered, which indicates that the application returns to the foreground, and the statistical count Count of the corresponding number c1 is increased. Similarly, the hidden page count object onActivityStopped is used to collect the value of the hidden page number c2, and only the corresponding c2 value is subtracted. If the page count count is reduced to 0, it is proved that the process returns to the background.

[0051] In a possible implementation, when the process is created, the process is bound to the remote service Service, including: when the process is created, the communication between the process and the remote service Service is established, and the corresponding display page count object onActivityStarted, hidden page count object onActivityStopped and page count of the process are created through the remote service Service, and the process is bound to the remote service Service.

[0052] In a possible implementation, the communication between the process and the remote service Service is established, including:

[0053] The Stub class between the process and the remote service Service is created through the binder object to realize the communication between the process and the remote service Service.

[0054] In a possible implementation, before the process is bound with the remote service Service, the method further includes: creating a local page lifecycle statistics class ActivityLifecycleCallbacks; collecting the cumulative value of the display page number of the process and collecting the cumulative value of the hidden page number of the process by the page lifecycle statistics class ActivityLifecycleCallbacks before the process is not bound with the remote service Service; and synchronizing the cumulative value of the display page number of the process and the cumulative value of the hidden page number of the process in the page lifecycle statistics class ActivityLifecycleCallbacks to the remote service Service after the process is bound with the remote service Service.

[0055] Before the communication between the process and the remote service Service is established, the cumulative value of the display page number of the process and the cumulative value of the hidden page number of the process can be collected by the local page lifecycle statistics class ActivityLifecycleCallbacks corresponding to the process, and after the communication is established, the data in the local page lifecycle statistics class ActivityLifecycleCallbacks is synchronized to the remote service Service, so as to ensure the accuracy of the page count.

[0056] If the process and the remote service Service have completed the binding, the display page count object onActivityStarted and the hidden page count object onActivityStopped are directly called to collect the cumulative value of the display page number of the process and the cumulative value of the hidden page number of the process, which is real-time response at this time. If the process and the remote service Service have not completed the binding, the display page count object onActivityStarted and the hidden page count object onActivityStopped are first used to maintain the cumulative value of the display page number of the process and the cumulative value of the hidden page number of the process to the count count2 in the local, and when the service binding is completed, if the count count2 is greater than 0, the display page count object onActivityStarted is called, the count count2 is synchronized to the remote service Service, and then the count count2 is set to 0; if the count count2 is less than or equal to 0, the hidden page count object onActivityStopped is called, the count count2 is synchronized to the remote service Service, and then the count count2 is set to 0.

[0057] In a possible implementation, synchronizing the display page count cumulative value and the hidden page count cumulative value of the process to the page count of the remote service Service includes:

[0058] The display page count object onActivityStarted and the hidden page count object onActivityStopped in the remote service Service are called by the process;

[0059] The display page count cumulative value of the process is collected in real time by the display page count object onActivityStarted, and the hidden page count cumulative value of the process is collected in real time by the hidden page count object onActivityStopped;

[0060] The page count of the remote service Service is synchronized according to the display page count cumulative value and the hidden page count cumulative value collected in real time.

[0061] In a possible implementation, the page count of the remote service Service is synchronized according to the display page count cumulative value and the hidden page count cumulative value collected in real time, including:

[0062] The page count is added to the display page count cumulative value collected in real time, and is subtracted from the hidden page count cumulative value collected in real time, to obtain a subtraction result, and the subtraction result is taken as a new page count.

[0063] In a possible implementation, the foreground and background of each process are detected according to the page count, including:

[0064] The foreground and background of each process are detected according to the page count and a foreground and background determination condition.

[0065] In a possible implementation, the foreground and background determination condition includes: when the page count is 1, it is determined that the corresponding process is in the foreground; and when the page count is 0, it is determined that the corresponding process is in the background.

[0066] In the App, the Application class of the system is implemented and is registered. In the onCreate callback of the Application, the bindService method of the system is called to bind the independent collection end process Service.

[0067] The application meets the privacy compliance requirements and multi-process foreground and background detection without permission, and has no requirement for system version, and almost no delay by using AIDL. At the same time, in order to avoid the page visible, the page process collects the count before the Service of foreground and background detection is bound, and updates when the Service of foreground and background detection is bound, so as to ensure the stable detection.

[0070] The remote service creation module 21 is used for creating a remote service Service, and the remote service Service is used for collecting the page count of the process.

[0071] The binding module 22 is used for binding the process with the remote service Service when the process is created, and each process has a corresponding page count in the remote service Service.
