Description

  The present invention relates to development support for application programs executed on a terminal.

  In recent years, mobile terminals such as smartphones have become more multifunctional, and the development work of application programs executed on mobile terminals has become complicated. In addition, it is difficult for the developer to predict how the application program will be used on the terminal at the development stage, and its usage can only be understood by the user when the application program is actually used. There are many. Depending on the usage mode, unnecessary processing may increase, causing a problem such as an increase in power consumption.

Therefore, an attempt has been made to memorize the situation when the application program is actually used and use it for developing the application program.
In claim 1 and paragraph 45 of Patent Document 1, module power consumption calculation means for calculating power consumption for each module, and a first calculation for calculating a resource consumption ratio for each method based on the “number of calls” of the method And a method. Patent Document 2 describes “state transition event”. Paragraph 80 of Patent Document 3 describes “a program evaluation apparatus that uses a calling relationship between modules”.

The mobile communication network 6 is connected to the communication line 3 and mediates communication between the terminal 2 and a device connected to the communication line 3 such as the analysis device 1. The mobile communication network 6 has communication facilities such as a plurality of base stations and an exchange station (not shown), and provides a communication service to the plurality of terminals 2 through these.

  The development device 4 is a device for developing an application program (hereinafter referred to as an application) executed on the terminal 2, and is a personal computer, for example. Further, the development device 4 has a function of acquiring an analysis result output from the analysis device 1 and expressing the result according to the analysis result, for example, a function of drawing a state transition diagram.

  The server device 5 is a device for registering an application developed by the development device 4. The server device 5 causes the terminal 2 to download an application registered in response to a request from the terminal 2. The terminal 2 is an information processing apparatus that requests an application from the server device 5 to acquire and execute the application, and is, for example, a mobile phone such as a smartphone. The analysis system 9 includes a plurality of terminals 2. The analysis device 1 is a device that acquires history information stored when the terminal 2 executes an application and analyzes the contents. The analysis device 1 is a computer, for example, and outputs the analysis result of history information to the development device 4.

1-2. Terminal Configuration FIG. 2 is a diagram illustrating a configuration of the terminal 2. The control unit 21 is means for controlling the operation of each unit of the terminal 2. The control unit 21 includes an arithmetic processing device such as a CPU (Central Processing Unit) and a storage device such as a ROM (Read Only Memory) and a RAM (Random Access Memory), and executes a program stored in these storage devices. The communication unit 23 is an interface that communicates applications, history information, and the like with the analysis device 1, the server device 5, and the like via the communication line 3. For example, the communication unit 23 is a wireless communication circuit that conforms to IMT-2000, IMT-Advanced, or the like. .

  The display unit 24 is a display device using liquid crystal or the like, and displays an image in accordance with an instruction from the control unit 21. The operation unit 25 has a touch panel, buttons, and the like for inputting various instructions. The operation unit 25 receives an operation by the user and supplies a signal corresponding to the operation content to the control unit 21. The positioning unit 26 measures (positions) the position of the terminal 2 based on a GPS (Global Positioning System) positioning method. The imaging unit 27 is configured to image the periphery of the terminal 2 and includes, for example, an optical system such as a lens and an imaging element such as a CMOS (Complementary Metal Oxide Semiconductor) image sensor.

  The storage unit 22 is a large-capacity storage unit such as a flash memory, and stores a program read by the control unit 21. The storage unit 22 may include a so-called removable disk, that is, a removable recording medium. In addition, when the control unit 21 executes an application, the storage unit 22 stores information regarding the execution of the application as history information 221.

1-3. Structure of History Information FIG. 3 is a schematic diagram for explaining history information 221 generated by executing an application. FIG. 4 is a diagram showing the generated history information 221. As shown in FIG. The control unit 21 of the terminal 2 calls and executes a plurality of modules by executing the application. Then, the called module calls and executes another module. Thereby, a plurality of modules are activated in parallel, and the control state of the control unit 21 transitions from one module to another module.

  For example, as illustrated in FIG. 3, when the module Ma is being executed, the control unit 21 is triggered by the execution of the method “onResume ()” as a module name “Ma” that is the name of this module. And the method name “onResume ()” that is the name of the method is stored in the history information 221. For example, when the user performs an operation of pressing a virtual button displayed on the display unit 24 on the operation unit 25, the control unit 21 acquires this operation and calls a method "onKeyDown ()". Run. When it is identified that the pressed button is a “back button”, the control unit 21 returns the exclusive right to the module Mb that has the exclusive right to display by the display unit 24 immediately before the module Ma.

  At this time, the control unit 21 receives the module name “Ma” of the module that transmitted the intent, the method name “onKeyDown ()” of the transmitted method, the event “back button press” that triggered the intent, The module name “Mb” of the module that received the tent and the method name “onResume ()” of the received method are stored in the history information 221.

  The control unit 21 distinguishes and stores the module call in the history information 221 for each module that made the call and the type of the call. For example, the control unit 21 stores the history information 221 by distinguishing between the case where the module is activated by normal activation as described above and the case where the module is activated by remote procedure call (RPC). The remote procedure call is a function call from an address space different from the address space used by the application of the terminal 2, for example, a function is called between modules in different process spaces.

  In addition, when the module is activated by the timer drive via the alarm manager which is one of the system management functions in the terminal 2, the control unit 21 distinguishes the history from the case of the normal activation activated from other modules. The information 221 is stored. When an argument is delivered or a return value is supplied for intent transmission / reception, the control unit 21 stores those values in the history information 221.

  As described above, the control unit 21 stores the names of the modules and methods involved in the transition in the history information 221 together with the time at the time of the state transition due to intent transmission / reception or the like. When the application ends, the control unit 21 calculates a total period during which the application has been operated (referred to as an application operation period). And the control part 21 memorize | stores the calculated application operation | movement period in the header part of the historical information 221 with the application name which is the name of the application, and the user name which is the name of the user who performed the application on the terminal 2. . The control unit 21 may store the start time and end time of the application in addition to the application operation period, and the control unit 21 stores the time when the user's operation is performed (referred to as operation time) and the user You may memorize | store and distinguish the time (it is called non-operation time) when this operation was not performed. In addition to the application operation period, the control unit 21 may store an operation period for each module. The operation time described above is the total time for which the app screen is displayed.

  The control unit 21 stores the history information 221 by dividing it into operation information for each module. In the example shown in FIG. 3, N modules from 1 to N are activated by executing the application, and information indicating each operation (referred to as module operation information) is stored in the history information 221. Module operation information includes the module name, module type, module start time and end time, transition time to other modules, event type that triggered the start, and resources used in executing the module Consumption and power consumption. Here, the resources refer to resources used for the application in the terminal 2, such as the CPU of the control unit 21, the storage unit 22, the communication unit 23, the positioning unit 26, and the imaging unit 27, for example.

1-4. Configuration of Analysis Device FIG. 5 is a diagram illustrating a configuration of the analysis device 1. The control unit 11 is means for controlling the operation of each unit of the analysis apparatus 1. The control unit 11 includes an arithmetic processing device such as a CPU and a storage device such as a ROM and a RAM, and executes a program stored in these storage devices. The communication unit 13 is an interface for communicating information with the communication line 3. For example, various modems, wireless communication circuits, serial interfaces compliant with the USB (Universal Serial Bus) standard, IrDA (Infrared Data Association) ) And other wireless interfaces.

  The storage unit 12 is a large-capacity storage unit such as a hard disk or a flash memory, and stores a program read by the control unit 11. The storage unit 12 may include a so-called removable disk, that is, a removable recording medium. In addition, the storage unit 12 stores a history database (hereinafter, “database” is expressed as “DB” in the figure) 121 and classification information 122.

1-5. Functional Configuration of Analysis Device FIG. 6 is a diagram illustrating a functional configuration of the analysis device 1. The control unit 11 of the analysis apparatus 1 functions as an acquisition unit 111, a calculation unit 112, a totaling unit 113, an output unit 114, and a classification unit 115.

  The acquisition unit 111 acquires a copy of the history information 221 from the plurality of terminals 2 via the communication unit 13 and stores them in the history database 121. FIG. 7 is a diagram showing the history database 121. A copy of the history information 221 acquired from each terminal 2 is stored as history information 1211 included in the history database 121.

  The classification unit 115 classifies the plurality of history information 1211 included in the history database 121 into groups, and stores the classification result in the storage unit 12 as the classification information 122. FIG. 8 is a diagram illustrating an example of the classification information 122. The classification unit 115 refers to the application name, the user name, and the application operation period described in the history information 1211, and based on these, the history information 1211 is grouped into a predetermined number (for example, three) according to a predetermined category. Classify. Specifically, the history information 1211 having the same application name and user name is extracted from the history database 121, and the application operation period included in the extracted history information 1211 is added for each date, so that Calculate the operating period per day for the app. In addition, three groups of a user (heavy user), a short user (light user), and another user (normal user) whose operation period per day of the application is long are defined, and the user corresponding to the history information 1211 Classify to the group to which it belongs. For example, as illustrated in FIG. 8, history information 1211 in which a common application name and user name are described includes a group in which the total application operation period per day of the corresponding user is less than 20 minutes, and 20 minutes or more 120 It is classified into a group of less than minutes and a group of more than 120 minutes.

Since the application operation period is a period during which the application is executed, the classification unit 115 in this case is an example of a classification unit that classifies the history information 1211 for each period during which the application is executed.
Further, the classification unit 115 may classify the history information 1211 in which a specific application name is described into a plurality of groups based on the above-described application operation period without classifying the history information 1211 for each user name described therein. Good. In this case, the history information 1211 is not classified according to the total application operation period per day of the corresponding user, but the history information 1211 is divided into a plurality of groups according to the application operation period itself described in the history information 1211. What is necessary is just to classify. Further, the application operation period used for classification may be any other time information (for example, operation time) included in the history information 1211. The group into which the history information 1211 is classified is not limited to three, and may be two or four or more.

  Based on the history database 121 acquired by the acquisition unit 111, the calculation unit 112 uses the power consumed by the executed module (referred to as the first module) as the module (referred to as the second module) that called the first module. ) Every time. Specifically, the consumption amount of the resources used in association with the execution of the module and the power consumption amount are extracted from the plurality of history information 1211 included in the history database 121, and the above-described power amount is calculated. The calculation unit 112 may perform this calculation for each group classified by the classification unit 115.

  The counting unit 113 counts the number of times the first module is called for each type of the second module and the calling of the second module. That is, the totaling unit 113 refers to the history database 121 and totals, for example, the number of times the module Ma has been activated by normal activation, the number of times by which the module Ma has been activated, and the number of times by which the alarm manager has been activated. . Note that the totaling unit 113 may perform this totaling for each group classified by the classification unit 115.

  The output unit 114 outputs the amount of power calculated by the calculation unit 112 and the number of times totalized by the totalization unit 113 for each combination of the first module and the second module and the group classified by the classification unit 115. To do. For example, in an application in which the module Ma, the module Mb, and the module Mc are respectively executed, when the module Ma is called from the module Mb and may be called from the module Mc, the calculation unit 112 is set as the first module. The amount of power consumed by the module Ma is calculated for each of the modules Mb and Mc as the second modules.

  That is, the calculation unit 112 calculates the amount of power consumed when the module Mb calls the module Ma (Mb → Ma) and the amount of power consumed when the module Mc calls the module Ma (Mc → Ma). Are calculated separately. Similarly, the summation unit 113 sums up the number of times that the module Mb called the module Ma (Mb → Ma) and the number of times the module Mc called the module Ma (Mc → Ma) separately. Then, the output unit 114 outputs the power amount and the number of times of Mb → Ma, and the power amount and the number of times of Mc → Ma, respectively.

  The output unit 114 may output actual data regarding the amount of power and the number of times, but may output information corresponding to the actual data. For example, the output unit 114 outputs information corresponding to the amount of power calculated by the calculation unit 112 and the number of times calculated by the totaling unit 113 as a character string according to a graph data description language that describes graph data. May be. FIG. 9 is a diagram illustrating an example of an output result output as a character string according to the graph data description language. The character string shown in FIG. 9 follows the rules of a graph data description language that describes data indicating a directed graph.

  For example, the variable “a” represents a block in which a character string “Act.Ma” is described in the first line and a character string “50 mAh” is described as a label in the second line, and the color is blue. Is set to The arrow drawn from the variable “a” to the variable “b” is set to have a thickness of “2 mm” and a color of yellow. That is, according to this character string, the amount of power and the number of calls for each combination of the first module and the second module are expressed by setting the line thickness and color. The character string output from the output unit 114 may represent a graph configured such that the line becomes thicker as the number of calls increases, or the color of the line becomes brighter as the power amount increases. A graph configured as described above may be expressed. The label described above may be determined according to the module name and the total amount of power consumed in the module.

  The character string output by the output unit 114 is transmitted to the development device 4 via the communication unit 13. The development device 4 has a function of interpreting a character string written according to the graph data description language described above and drawing a directed graph according to the content. FIG. 10 is a diagram illustrating an example of a directed graph drawn in the development device 4. In the directed graph shown in FIG. 10, the number of calls between modules and the amount of power consumed thereby are expressed by the thickness and color of the arrow lines connecting the modules. When the application is executed on the terminal 2, it is easy to grasp which module is called more times and the power consumption is larger in accordance with the user's operation. As a result, the app developer can get suggestions on how to modify the app.

  Further, the analysis device 1 classifies the plurality of history information 1211 included in the history database 121 into a plurality of groups, and outputs the electric energy and the number of times for each group. It is easy to notice inherent problems. For example, since the classification unit 115 described above classifies the plurality of history information 1211 into a plurality of groups according to the total application operation period per day of the corresponding user, the application developer has a long application operation period. In this case, it is easy to notice a problem that occurs in the user and a problem that occurs in the user when the application operation period is short.

2. Modification The above is the description of the embodiment, but the contents of this embodiment can be modified as follows. Further, the following modifications may be combined.

2-1. Modification 1
In the above-described embodiment, the control unit 11 of the analysis apparatus 1 functions as the classification unit 115, but may not have this function. In this case, the acquisition unit 111 may acquire a copy of the history information 221 stored for one predetermined application from the plurality of terminals 2. Even in this configuration, the analysis apparatus 1 uses the number of times the second module calls the first module and the number of times the first module is called for each combination of the first module and the second module that calls the first module. The user can be notified of the amount of power consumed.

2-2. Modification 2
In the above-described embodiment, the control unit 11 of the analysis apparatus 1 classifies the plurality of history information 1211 included in the history database 121 into groups according to the total application operation period per day of the corresponding user. Instead of or in addition to the application operation period, the history information 1211 may be classified for each type of resource used for the application. For example, when the application uses any of the resources of the CPU, the storage unit 22, the communication unit 23, the positioning unit 26, and the imaging unit 27, the control unit 11 uses these usage amounts (for example, usage time and usage count). ) May be subjected to multivariate analysis to classify each piece of history information 1211 into a plurality of groups. Specifically, the history information 1211 may be classified for each tendency that is clustered according to an algorithm such as the k-average method and reflected in the history information 1211. That is, in this case, the control unit 11 functions as a classification unit 115 that classifies the history into a plurality of groups for each type of resource used in the application program. Since the application operation period is different for each history information 1211, the control unit 11 may classify based on the usage amount per unit time obtained by dividing the resource usage amount by the application operation period.

2-3. Modification 3
Further, the control unit 11 of the analysis apparatus 1 may classify the history information 1211 for each environment in which the application is executed instead of or in addition to the application operation period. For example, when the terminal 2 is operated by a user who moves on a train or the like, if the terminal 2 communicates using the communication unit 23, the base station connection is more frequent than when the user is stationary. Switching occurs. Each time the connection is switched, the terminal 2 that has detected the connection executes a process for searching for a new communication path in the background process, so that a module is called. Accordingly, the history information 1211 has different contents depending on the connection switching frequency. In this case, the control unit 11 may specify the connection switching frequency and classify the history information 1211 into a plurality of groups according to the specified frequency. For example, it is classified into three groups that are stationary, in which switching per unit time does not occur, during high-speed movement where the number of connection switching per unit time is greater than a predetermined number, during low-speed movement where the number of switching per unit time is less than a predetermined number. . That is, in this case, the control unit 11 functions as the classification unit 115 that classifies the history into a plurality of groups for each environment in which the application program is executed. According to this configuration, the plurality of pieces of history information 1211 included in the history database 121 are classified into a history when the application is executed while moving at high speed or low speed, and a history when the application is executed without moving. Therefore, it becomes easy for the developer of the application to notice a defect corresponding to each use environment.

2-4. Modification 4
Further, the control unit 11 of the analysis apparatus 1 may classify the history information 1211 for each application setting instead of or in addition to the application operation period. The application setting is, for example, a setting as to which of the two systems, LTE and 3G, is given priority as a communication network. The setting data consists of a set of one or more setting item names and setting values. In the above example, the setting item name is “communication network”, and the setting value is “1” for LTE, for example “1” for 3G. 0 ". When there are a plurality of these settings, the history information 1211 may be classified into a plurality of groups by performing multivariate analysis on the setting values corresponding to the plurality of setting items. Specifically, the history information 1211 may be classified for each tendency that is clustered according to an algorithm such as the k-average method and reflected in the history information 1211. That is, in this case, the control unit 11 functions as the classification unit 115 that classifies the history into a plurality of groups for each setting of the application program executed on the terminal. According to this configuration, for example, in a plurality of terminals 2, since the history stored in the terminal 2 is classified according to the setting of each user, the developer of the application is in trouble according to the preference of each user's setting. It becomes easy to notice.

2-5. Modification 5
In the above-described embodiment, the control unit 11 of the analysis apparatus 1 functions as the output unit 114 that outputs the calculated power amount and the total number of times for each combination of the first module and the second module. However, the output unit 114 that outputs the amount of power consumed and the number of calls for each order of calling by the second module that called the first module and one or more third modules that called the second module. May function as

  For example, suppose that the developer of the application in which the module Ma, the module Mb, and the module Mc are called does not need to call the module Mc directly from the module Ma. In this case, the developer of the application provides the module Ma with a function of calling the module Mb and provides the module Mb with a function of calling the module Mc, but does not provide the module Ma with a function of calling the module Mc.

  On the other hand, if an actual user often wants to activate the module Mc when the module Ma is active, the module Mc cannot be directly called when the module Ma has the exclusive right to display. Therefore, the user starts the module Mb once, and frequently performs an operation of starting the module Mc via the module Mb. When the application is designed in this manner, the module Mb that does not require the user to start is frequently started, so that useless power is consumed and useless resources are used. However, since the actual usage by the user is unknown, the application developer may not be aware of such a design waste.

  The control unit 11 functions as the output unit 114 that outputs the amount of power consumed and the number of calls for each calling order described above, so that the activation in the order of the module Ma → module Mb → module Mc is frequently performed. If the application developer knows that the module Mb is being executed, the module developer can notice that the module Mb is activated only for the activation of the module Mc. In this case, the developer of the application solves this problem by providing the module Ma with a function of directly calling the module Mc. In other words, according to this configuration, the developer of the application can notice a complicated operation procedure that the user has inevitably created from the restrictions of the current functions, and it is easy to make a design change to change it to a simple one. In the above-described example, the control unit 11 performs output in the order in which the three modules are called. However, the control unit 11 may perform output in the order in which four or more modules are called. The order of monitoring by the control unit 11 may be limited to calls that occur within a predetermined time.

2-6. Modification 6
In the embodiment described above, the positioning unit 26 measures the position of the terminal 2 by GPS. However, the position of the terminal 2 may be specified by an inquiry to a location register that performs so-called position registration. Here, the location register is a device that stores which radio base station cell (communication range) connected to the mobile communication network 6 the terminal 2 that is a radio device is in.

2-7. Modification 7
The program executed by the control unit 11 of the analysis apparatus 1 is a recording medium readable by a computer device, such as a magnetic recording medium such as a magnetic tape or a magnetic disk, an optical recording medium such as an optical disk, a magneto-optical recording medium, or a semiconductor memory. Can be provided in a stored state. It is also possible to download this program via a network such as the Internet.

2-8. Modification 8
In the embodiment described above, the calculation unit 112 realized by the control unit 11 uses the first module to calculate the amount of power consumed by the executed first module based on the history database 121 acquired by the acquisition unit 111. Although it is calculated for each called second module, it is also possible to specify only a numerical value from which the amount of power can be calculated. That is, calculating the electric energy includes specifying a numerical value from which the electric energy can be calculated. For example, when the voltage supplied to the terminal 2 such as a mobile phone can be considered to be constant, the control unit 11 can calculate the electric energy by specifying the current. Therefore, the control unit 11 may calculate the current used by the first module instead of the electric energy for each second module that calls the first module.
