Referring to Figure 2, an exemplary embodiment provides a method executable by the computing device 1, to acquire the display speed of a page of an application running in the computing device. The method comprises:

S I : acquiring log information of the page;

S2: filtering the log information to obtain display information of the page; and S3: analyzing the display information to obtain the display speed of the page. According to the method, the display speed of the page can be obtained by analyzing the display information of the page so that tedious timing process can be avoided and the accuracy requirements can be met.

According to an exemplary embodiment, the applications may include game programs, video programs, call programs and so on. The applications can also include programs for word processing, information retrieval, media player, network communications, information management, drawing, image capture, spreadsheets and so on. The application may have one or more activity components. Each component can correspond to a page of the application. For example, the applications may have, for example, a main menu page, a dial page or a setting page. These pages can usually include one or more user interfaces for interacting with the user. For example, a user can enter a phone number on the dial page of the call program to start dialing task, and the user can also choice a camera button on the image capturing main menu page, to start image capturing tasks. Generally, when a user starts an application, an activity of the application is usually initiated simultaneously. The activity component which is active can trigger another activity component, resulting the change of the displayed application page. Whenever an activity component is initiated, the previous activity component is deactivated. The page display speed corresponds to the time period from initiating the activity component until the page corresponding to the activity component is displayed on the display unit (for example, the display surface). The shorter the time period is, the faster the page is displayed.

In addition to the application, the computing device may also is stalled with an operating system, for example, Windows Phone, Symbian, iOS, Android, Windows, Linux , etc.

According to an exemplary embodiment, during the application being running, log information of the application is recorded in a system log file. The log information of the application may indicate the status of the application. For example, the log information may include startup time, shutdown time, error, error-related information of the application, etc. The system log file can be output.

Taking the android system as an example, for example, the system log file can be retrieved and output via a command-line tool "logcat". The page log information of the application is included in the system log file. The page log information includes log information associated with the components of the application, such as the class name of the components, and the time period required for displaying the page of each component.

Computing devices with Android system usually are equipped with Android SDK (Software Development Kit), which is a core software development kit dedicated to Android application development. The applications page log information can be acquired from the system log file via "adb logcat -s ActivityManager" command. It should be noted that, before using the "adb logcat -s ActivityManager" command to acquire the applications page log information, "adb logcat -c" command can be used to remove any cached log information of the application, so that, at step S I, only the page log information corresponding to the currently displayed page of the application is acquired. Of course, if not removing the cached log information of the application, at step SI, the acquired page log information would include possibly both page log information corresponding to the currently displayed page and page log information corresponding to previously displayed page.

After acquiring the page log information of the application, at step S2, the findstr

"Displayed" command can be used to filter the log information to obtain display information of the page. The page display information includes information related to the display of the page, such as the time period required for displaying the page. In combination with the command for acquiring the page log information of the application, the following command can be used to perform steps SI and S2, to obtain the page display information in the page log information:

adb logcat -c && adb logcat -s ActivityManager I findstr "Displayed"

Instead of the above command for performing step S 1 and step S2, a packaged program can be used to perform steps S 1 to step S2. Especially for mobile terminals (such as smart phones, tablet computers), the packaged program is particularly advantageous. For example, the packaged program may include the following design using JAVA language:

mLogcatProc = Runtime. getRuntime().exec(new String[]

{ "logcat", "ActivityManagenI *:S" })

Figure 3 shows the page display information of the application obtained by the above command adb logcat -c && adb logcat -s ActivityManager I findstr "Displayed". As shown in figure 3, the page display information of the application comprises the package name of the application, i.e. "activity com. example. Logowner", the class name of the active activity component, i.e. "GetlogActivity" and the time period required for displaying the page, "317ms". The display speed of the page is associated with the time period required for displaying the page.

In step S3, the page display information is analyzed to obtain the display speed of the page. In step S3, a preset keyword may be used to extract the package name of the application, the class name of the page and the time period required for displaying the page from the page display information. Typically, the page display information of the application based on the Android system has the same format. For example, referring to Figure 3, the package name of the application is located between "Displayed" and "/" , the class name of the page is located between "/" and ": ", the time period required for displaying the page is located between ": " and "ms". Accordingly , the preset keyword may include "Displayed", "/", ": " and "ms". In step S3, the package name of the application, the class name of the page and the time period required for displaying the page may be extracted from the content preceding or following the keyword. The package name of the application, the class name of the page and the time period required for displaying the page may be output through the display unit 17 to show the display speed of the page to the user, as shown in Figure 4.

In an exemplary embodiment, the JAVA code for implementing step S 1 and step S2 is as follows:

mLogcatProc = Runtime.getRuntime().exec(new String[]

{ "logcat","ActivityManager:I *:S" });

reader = new BufferedReader(new

InputStreamReader(mLogcatProc.getlnputStreamO))

The JAVA code for extracting the package name of the application in step S3 is as follows:

int pkgindexl = line.indexOf("Displayed") ;

String newline = line.substring(pkgindexl);

int pkgindex2 = newline.indexOf("/");

String pkg = newline. substring(9,pkgindex2)

The JAVA code for extracting the class name of the page is as follows:

String newline2 = newline. substring(pkgindex2);

int Activity Index = newline2.indexOf(":");

String ActivityName = newline2.substring(l, Activity Index)

The JAVA code for extracting the time period required for displaying the page is as follows: String time = newline2.substring(newline2.indexOf("+")+l,

newline2.indexOf("ms")).

Referring to Figure 5, an exemplary embodiment also provides an apparatus 100 for acquiring the page display speed of an application which comprises an acquiring module 101, a filtering module 102 and an analyzing module 103.

The acquiring module 101 may acquire the page log information of the application and before acquiring the log information, remove any information associated with the log of the application in a cache.

The filtering module 102 may filter the log information to obtain display information of the page. The display information of the page comprises a package name of the application, a class name of the page and a time period required for displaying the page. The display speed of the page is associated with the time period required for displaying the page.

The analyzing module 103 may analyze the display information to obtain the display speed of the page. The package name of the application, the class name of the page and the time period required for displaying the page may be extracted from the display information of the page, using preset keywords. The package name of the application, the class name of the page and the time period required for displaying the page may be presented on the display unit.

The method and apparatus for acquiring the display speed of application pages can meet the accuracy requirements without tedious timing process.
