Description
Technical Field
The invention relates to the technical field of computer networks, in particular to an Alarm optimization management method and system.
Background
In the Android system, the alarmmmanagerservice is responsible for setting and managing the alarms (timers) of all applications. The AlarmManagerService defines an ArrayList < Batch > mArlarmBatches array for managing Alarm, and each Batch (timer set) defines an ArrayList < Alarm > arms array, and each Batch is composed of a plurality of Alarm. When the application cancels the Alarm or the Alarm manager service judges that the Alarm is invalid, the Alarm is deleted from the Batch list, and at the moment, the Batch array needs to be reconstructed, so that the Alarm can be more effectively reconstructed into a proper Batch list. The current practice is to remove all the alarms from the Batch list, remove the already constructed Batch list, then reconstruct a new Batch list, and add the alarms to the Batch list again. When there are many Alarm and many Alarm cancel operations, the operations are laborious and time consuming, and the Alarm manager service operates in the system process, which affects the efficiency of the system.

And constructing a to-be-adjusted Batch Index list (which is equivalent to the to-be-adjusted timer set identification list), recording the Bath Index of the Batch with the changed start value in the Batch Index list after deleting the Alarm, then finding the corresponding Batch according to the list, reserving the inside Alarm, deleting the Batch, and then adding the reserved Alarm into each Batch of the Batch list.
Further, the step S450 includes the steps of:
s451, according to an adding rule of Alarm, judging whether the Alarm can be added to the existing timer set of the timer set list, if so, entering the step S452; otherwise, go to step S453;

Adding the reserved Alarm to each Batch of the Batch list, wherein one can be added to the existing Batch according to the adding rule of the Alarm, and the other cannot be added to the existing Batch, at this time, we need to reconstruct a Batch according to the starting time and the latest arrival time of the Alarm, the Batch is listed in the Batch list, and the Alarm is also added to the reconstructed Batch.
Further, the adding rule of the Alarm is as follows: and when the starting arrival time value of the Alarm is smaller than the latest arrival time value of the timer set, and the latest arrival time value of the Alarm is larger than the starting arrival time value of the timer set, adding the Alarm to the timer set.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention discloses an Alarm optimization management method, which comprises the following steps of:
s100, when there is an Alarm to be deleted, traversing the Alarm list of each timer set in the timer set list according to the identifier of the Alarm, judging whether the Alarm is matched with the Alarm to be deleted, if so, entering the step S200, and otherwise, ending the operation;
s200, recording the identifier of the timer set, and deleting the matched Alarm in the timer set;
s300, according to the initial arrival time value and the latest arrival time value of the remaining Alarm in the timer set, obtaining a new initial arrival time value and a new latest arrival time value of the timer set, judging whether the new initial arrival time value of the timer set is consistent with the original initial arrival time value, and if so, ending the operation; otherwise, entering step S400;
s400, reserving the rest Alarm in the timer set, deleting the timer set, and adding the rest Alarm to each timer set in the timer set list.
Many applications in the system use many timers, most of which have less strict requirements on accuracy, for example, an application may connect a network once every a period of time, and as for whether this time is acceptable for a five-minute or ten-minute application, when setting such timers, the application sets the initial arrival time when (e.g., five minutes) and the latest arrival time maxWhen (e.g., ten minutes) of Alarm, and the underlying system, in order to save power, i.e., to avoid too much power consumption by waking up the system by time-neighboring Alarm, puts such Alarm with intersection into a timer set, calculates the start (initial arrival time) and end (latest arrival time) values of the timer set, and when the start arrives, i.e., all the Alarm under the timer set are considered to arrive, all the Alarm can be applied according to its own situation.
The system has a timer set list, each timer set has an Alarm list, when the Alarm is deleted, all the alarms in the timer sets are matched through the identification of the alarms, if the alarms are not matched, the alarms do not exist, and the operation is finished. And once the match is obtained, recording the identifier of the timer set where the Alarm is located, and deleting the corresponding Alarm from the timer set. And then determining whether a start (start-to-time) value of the timer set needs to be adjusted according to the start-to-time and the latest arrival time of the remaining alarms, if the start-to-time and the latest arrival time of the timer set do not need to be adjusted, then not needing to reconstruct a subsequent timer set list and re-add the alarms, and ending the operation, if the start value needs to be adjusted, then reserving all the remaining alarms under the timer set, deleting the timer set from the timer set list, and then adding the previously reserved alarms into the timer set list. Therefore, at most, only the alarms in the adjusted timer set need to be added, instead of reconstructing the whole timer set list and then adding all the alarms again, and the efficiency needs to be improved greatly relatively.
A second embodiment of the method of the present invention, as shown in fig. 2, is based on the above embodiment, and details the process of step S300, specifically, the embodiment includes the steps of:
s100, when there is an Alarm to be deleted, traversing the Alarm list of each timer set in the timer set list according to the identifier of the Alarm, judging whether the Alarm is matched with the Alarm to be deleted, if so, entering the step S200, and otherwise, ending the operation;
s200, recording the identifier of the timer set, and deleting the matched Alarm in the timer set;
s310, acquiring all start time values and latest arrival time values of Alarm left by the timer set;
s320, taking the maximum starting time value of the rest Alarm as a new starting time value of the timer set, and taking the minimum latest arrival time value of the rest Alarm as a new latest arrival time value of the timer set;
s330 determines whether the new start time value of the timer set is consistent with the original start time value of the timer set? If yes, go to step S500; otherwise, the process proceeds to step S400.
S400, reserving the rest Alarm in the timer set, deleting the timer set, and adding the rest Alarm to each timer set in the timer set list.
When deleting the Alarm, adjusting rules of a start value and an end value of the timer set: the largest value of the remaining initial arrival time when of all the alarms is the new start value of the timer set, and the smallest value of the remaining maxWhen of the latest arrival time maxWhen of all the alarms is the new end value of the timer set. For example, if the start value of one timer set is 10; end value is 50; if the maximum of the remaining ranges is 10 after the first range is deleted, and the minimum of maxWhen is 50, that is, the start value and the end value of the timer set do not need to be adjusted; if the second alias is deleted, the maximum of the remaining aliams is 20, and the minimum of maxWhen is 60, then the start value of the timer set is adjusted to 20, and the end value is still 50.
A third embodiment of the method of the invention, as shown in fig. 3, comprises the steps of:
s100, when there is an Alarm to be deleted, traversing the Alarm list of each timer set in the timer set list according to the identifier of the Alarm, judging whether the Alarm is matched with the Alarm to be deleted, if so, entering the step S200, and otherwise, ending the operation;
s200, recording the identifier of the timer set, and deleting the matched Alarm in the timer set;
s300, according to the initial arrival time value and the latest arrival time value of the remaining Alarm in the timer set, obtaining a new initial arrival time value and a new latest arrival time value of the timer set, judging whether the new initial arrival time value of the timer set is consistent with the original initial arrival time value, and if so, ending the operation; otherwise, entering step S400;
s410, constructing a list of identifiers of a timer set to be adjusted, and adding the identifiers of the timer set to the list of identifiers of the timer set to be adjusted;
s420, deleting the same timer set identifier in the timer set identifier list to be adjusted;
s430, according to the list of the timer set identifiers to be adjusted, finding a corresponding timer set according to the timer set identifiers;
s440, reserving all Alarm in the timer set and deleting the timer set;
s450 adds all remaining alarms to the timer set of the timer set list.
Deleting the timer set and the condition for adding the reserved Alarm again after deleting the Alarm: the timer set needs to be deleted and the reserved Alarm needs to be added again only if the start (start-to-time) value of the timer set changes. If only the end (latest time of arrival) value changes, it is not needed.
In this embodiment, by establishing an identifier list of a timer set to be adjusted, an identifier of the timer set from which the Alarm is deleted and the start value is changed is added to the identifier list of the timer set to be adjusted. Then, according to the list of the timer sets to be adjusted, finding out the corresponding timer set, retaining all the alarms in the corresponding timer set, and then deleting the timer set. And adding all remaining alarms to each timer set in the timer set list. Therefore, all the timer set lists do not need to be overturned again, only a part of the selected timer sets are required to be deleted and added, and the selected timer sets are identified in the timer set identification list to be adjusted, so that the subsequent searching and operation are facilitated, and the working efficiency is greatly improved.
Preferably, on the basis of the above embodiment, the step S450 is detailed, and as shown in fig. 4, the step S400 includes the steps of:
s410, constructing a list of identifiers of a timer set to be adjusted, and adding the identifiers of the timer set to the list of identifiers of the timer set to be adjusted;
s420, deleting the same timer set identifier in the timer set identifier list to be adjusted;
s430, according to the list of the timer set identifiers to be adjusted, finding a corresponding timer set according to the timer set identifiers;
s440, reserving all Alarm in the timer set and deleting the timer set;
s451, according to an adding rule of Alarm, judging whether the Alarm can be added to the existing timer set of the timer set list, if so, entering the step S452; otherwise, go to step S453;
s452 adding the Alarm to the set of timers;
s453, establishing a new timer set according to the initial arrival time value and the latest arrival time value of the Alarm, and adding the Alarm to the new timer set, wherein the initial arrival time of the new timer set is the initial arrival time of the Alarm, and the latest arrival time of the new timer set is the latest arrival time of the Alarm; adding the new timer set to the timer set list.
Reconstructing a timer set list according to all remaining alarms, if the alarms do not conform to an adding rule for adding the timer set, reestablishing a timer set, including the alarms into the timer set, wherein the starting time and the latest time of the timer set are consistent with the alarms, and the timer set is also listed in the timer set list; if the adding rule is met, the Alarm is added to the timer set, and the new start time-to-time and the latest time-to-time in the timer set are updated.
Preferably, the adding rule of Alarm is as follows: and when the starting arrival time value of the Alarm is smaller than the latest arrival time value of the timer set, and the latest arrival time value of the Alarm is larger than the starting arrival time value of the timer set, adding the Alarm to the timer set.
Preferably, on the basis of any of the above embodiments, the following steps can be added:
s450, acquiring the starting arrival time value of each timer set, and setting the starting arrival time of the timer set with the first arrival of the starting arrival time to the bottom layer drive.
Because the management of the Alarm in the present invention involves the addition and deletion of the Alarm in the timer set, and along with the addition and deletion of the Alarm, the start arrival time (hereinafter, start) and the latest arrival time (hereinafter, end) values in the corresponding timer set (hereinafter, simply called Batch) also change correspondingly, and the following illustrates the calculation process of the start value and the end value of the timer set when adding or deleting:
many applications in the system use many timers, most of which have less strict requirements on accuracy, for example, an application connects a network once every a period of time, and as for whether this time is acceptable for a five-minute or ten-minute application, when setting such timers, the application sets the initial arrival time when (e.g., five minutes) and the latest arrival time maxWhen (e.g., ten minutes) of Alarm, and in order to save power, i.e., to avoid too much power consumption by waking up systems with time-adjacent Alarm, the underlying system puts such Alarm with intersection into a Batch, calculates the start and end values of the Batch, sets the start value of the Batch into the underlying driving system, and when the start arrives, it is considered that all the Alarm under the Batch are arrived, and all the Alarm can be applied according to their own conditions.
Rule to determine to which Batch Alarm fits can be added: the initial arrival time when of Alarm is less than the end value of Batch, while the latest arrival time maxWhen of Alarm is greater than the start value of Batch.
After Alarm is added to Batch, the start and end values of Batch adjust the rule: if the starting time duration when of the Alarm is greater than the start value of the Batch, the new start value of the Batch is the starting time duration when of the Alarm; if the latest arrival time maxWhen of Alarm is less than the end value of Batch, the new end value of Batch is the latest arrival time maxWhen of the Alarm.
Examples are as follows:
the application sets the first Alarm: the initial arrival time when1 is 10 minutes, the latest arrival time maxWhen1 is 50 minutes, and the system meets the requirement from 10 to 50;
since this is the first Alarm, the start value of Batch is when1(10) and the end value is maxWhen1(50)
The application sets a second Alarm: the initial arrival time when2 is 5 minutes, the latest arrival time maxWhen2 is 40 minutes, and the system meets the requirement from the interval of 5 to 40 to the arrival time;
at this time the start-up time whin 2(5) < end (50) of Batch, while maxWhen2(40) > start (10) of Batch, the Alarm may be added to Batch while adjusting the start and end values of Batch: since the start time when2(5) is not greater than the start (10) of the Batch, the start value of the Batch does not need to be adjusted, and since the latest arrival time maxWhen2(40) is less than the end (50) of the Batch, the end value of the Batch is adjusted to maxWhen2(40), the start of the Batch is still 10, and the end value is 40
The application sets the third Alarm: the initial arrival time when3 is 20 minutes, the latest arrival time maxWhen3 is 60 minutes, and the system meets the requirement from the interval of 20 to 60;
at this time the start-up time whin 3(20) < end (40) of Batch, while maxWhen3(60) > start (10) of Batch, the Alarm may be added to Batch while adjusting the start and end values of Batch: since the start time when3(20) is greater than the start time 10 of the Batch, the start value of the Batch is adjusted to when3(20), and the latest arrival time maxWhen3(60) is not less than the end 40 of the Batch, the end value of the Batch does not need to be adjusted, and at this time, the start time of the Batch is still 20 and the end value is 40.
The application sets the fourth Alarm: the initial arrival time when4 is 25 minutes, the latest arrival time maxWhen4 is 35 minutes, and the system meets the requirement from the interval of 25 to 35;
at this point the start-up time whin 4(25) < end (40) of Batch, while maxWhen4(35) > start (20) of Batch, the Alarm may be added to Batch while adjusting the start and end values of Batch: since the start-time when4(25) is greater than the start (20) of the Batch, the start value of the Batch is adjusted to when4(25), and the latest arrival time maxWhen4(35) is less than the end (40) of the Batch, the end value of the Batch is adjusted to maxWhen4(35), where the start of the Batch is 25 and the end value is 35
Through the above example, in practice, the system integrates four alarms into one Batch, and the start values of the Batch are all in the valid intervals of the four alarms, so that only the start value of the Batch needs to be set to the bottom drive, and after the start value of the Batch arrives, that is, the four alarms are all considered to arrive at the time, the application with the alarms can perform relevant application processing.
When deleting the Alarm, the start value and the end value of the Batch adjust the rule: the largest value of the remaining initial arrival time when of all the alarms is the new start value of the Batch, and the smallest value of the remaining maxWhen of the latest arrival time maxWhen of all the alarms is the new end value of the Batch.
Still the above example:
if the first Alarm is deleted, the maximum of the when of the remaining three Alarms is 25, and the minimum of maxWhen is 35, i.e. the start value and the end value of Batch do not need to be adjusted;
if the second Alarm is deleted, the maximum of when in the remaining three Alarms is 25, and the minimum of maxWhen is 35, i.e. the start value and the end value of Batch do not need to be adjusted;
if the fourth Alarm is deleted, the maximum of the wyen of the remaining three Alarms is 20, and the minimum of maxWhen is 40, the start value of Batch is adjusted to 20, and the end value is adjusted to 40. Returning to the state before the fourth Alarm is added.
In the last embodiment of the method of the present invention, when performing the Alarm deletion, all the alarms in the Batch are matched by the identifier of the Alarm, and if the match is not found, it indicates that the Alarm does not exist, and the operation ends. Once a match is made, the Batch Index (timer set identification) in which the Alarm is located is recorded, and the corresponding Alarm is deleted from the Batch. And then determining whether the start value of the Batch needs to be adjusted according to the start time and the latest arrival time of the rest of the Alarm, if not, not needing to reconstruct the Batch list and re-add the Alarm, if the start value needs to be adjusted, reserving all rest of the Alarm under the Batch, deleting the Batch from the Batch list, and then adding the previously reserved Alarm into the Batch list. Therefore, at most, only one Alarm in the Batch needs to be added, the whole Batch list is not reconstructed, and all Alarms are added again, so that the efficiency is improved greatly. The present embodiment includes two parts: and constructing a Batch Index list corresponding to the Alarm, and adding the Alarm again according to the Batch Index list.
A first part: constructing a Batch Index list corresponding to Alarm, comprising:
when the application deletes the Alarm which is also due, an interface function removeLocked provided by the alarmManagerService is called, and the removeLocked provides three sets of parameter definitions:
public void removeLocked(PendingIntent operation)
public void removeLocked(String packageName)
public void removeLocked(int userHandle)
there are two important member definitions in the data structure of Alarm:
public PendingIntent operation；
public int uid；
PendingIntent is the sent Intent when Alarm expires, and Alarm to delete can be found by matching PendingIntent in the Alarm data structure in the Batch list. The packageName is the package name of the application where the Alarm is located, and the package name where the Alarm is located can be obtained through the member function getTargetPackage of PendingIntent. The userHandle is the uid of the application where the Alarm is located, and the Alarm to be deleted can be matched by directly matching the member uid of the Alarm in the Batch list. When the parameter is the package name or uid of the application, all the items to be deleted under the corresponding application are identified, so the Batch Index to be recorded must be a list array, and thus the Batch corresponding to all the items to be deleted can be recorded, which is convenient for reconstructing the Batch list. The flow chart is as shown in fig. 5, the system has a Batch list, an Alarm list is below each Batch, the Batch list is firstly traversed, for each Batch in the list, the following Alarm list needs to be traversed to determine whether there is an Alarm to be deleted in the Batch list, if there is an Alarm to be deleted in the Batch list and the Start value of the Batch is adjusted at the same time (the maximum starting time of the remaining Alarm is the new Start value of the Batch, the minimum latest time of the remaining Alarm is the new end value of the Batch, when the new Start value is inconsistent with the original Start value, adjustment is needed), the Index corresponding to the Batch is recorded, and if there is no matched Alarm, the Batch is continuously traversed until the complete Batch list is traversed. Finally, record all Batch indexes that need reprocessing. The last recorded list of Batch indexes needs to delete the same Batch Index through traversal so as to avoid repeated operations when a new Batch is built subsequently.
It should be noted that, when the parameter of removelolocked in the flowchart is PendingIntent or uid, the PendingIntent or uid member is directly obtained from the Alarm structure for matching. When the parameter is the application package name, acquiring PendingIntent from the Alarm structure, calling a getTargetPack function in the PendingIntent to acquire the package name of the application of the Alarm, and then matching.
A second part: add Alarm again according to the Batch Index list:
when the Alarm delete is completed, all the corresponding batchs needing to be adjusted are added into the Batch Index list. The Batch list needs to be adjusted next. The operation of adjusting Batch enters the rebatch alarmsLocked function of AlarmManagerService. The specific flow is shown in fig. 6:
first, a list of the Batch Index where the Alarm is deleted and the start value of the Batch has changed needs to be traversed, the corresponding Batch instance is fetched according to the Batch Index, the remaining Alarm is retained, and the Batch is deleted. The setImpl function of AlarmManagerService is called later to add the saved Alarm to the Batch list again. When all the operations of the corresponding Batch in the Batch Index list are completed, a rescheduleKernel AlarmmsLocked function of AlarmManagerService is called to set the start value of the latest Batch to the bottom drive.
The invention has the advantages that: whether the Batch needs to be adjusted is determined by whether the start value of the Batch is changed, the Batch list does not need to be completely rewound, and the system efficiency is optimized.
