< example >
The general concept of this embodiment is to provide a new technical scheme for acquiring a wireless network, where when an application function provided by an application page includes a wireless network access function, scanning in advance to acquire an accessible wireless network and storing a corresponding wireless network list in a local cache, and when a user starts the wireless network access function, directly reading the wireless network list and displaying the wireless network list to the user for the user to select an accessed wireless network, so that the user can directly acquire the wireless network list without waiting after starting the wireless network access function, thereby greatly shortening the waiting time of the user, improving the speed of acquiring the wireless network by the user, and improving the wireless network acquisition experience of the user. The method is particularly suitable for application scenes that a user expects to quickly surf the internet or application programs need to quickly connect with the network.
< method >
In the present embodiment, a wireless network acquisition method is provided. The wireless network is a communication network implemented by wireless communication technology. For example, the wireless network may be a wireless local area network, and more specifically, the wireless network may be a Wifi network.
The wireless network acquisition method, as shown in fig. 2, includes: steps S2100-S2300.
Step S2100 receives an opening operation of a target application page by a user, and detects whether an application function provided by the target application page includes a wireless network access function.
A target application page is a page that provides one or more application functions. The application function is a function of calling a function module related to the electronic device displaying the application page to provide an application service, and may include calling an audio or video playing function realized by an audio or video player, calling an image shooting function realized by a camera, or calling a wireless network access function realized by a wireless network communication module.
In this embodiment, the target application page may be a page displayed when an application program provides an application service, or may be a page displayed when an operating system of the electronic device implementing this embodiment provides a system service.
The opening operation of the target application page by the user can be an operation that the user opens the target application page by clicking a jump operation, or an operation that the user reopens the target application page by clicking a refresh operation.
After the target application page is opened, whether the application function provided by the target application page comprises a wireless network access function is detected, the wireless network which can be accessed can be obtained when the target application page comprises the wireless network access function in combination with the subsequent steps, and the corresponding wireless network list is stored in a local cache, so that the wireless network list can be directly read and displayed to a user to select a wireless network to be accessed when the user starts the wireless network access function, and the speed of obtaining the wireless network by the user is improved.
In one example, the step of detecting whether the application function provided by the target application page includes a wireless network access function, as shown in fig. 3, includes: steps S2110-S2120.
Step S2110, monitoring the initialization opportunity of the page component corresponding to the target application page.
In this embodiment, the page component corresponding to the target application page is a component that is implemented based on a development language used for developing the target application page or a supported operating system, and provides an application function of a display page for interacting with a user to provide the page. For example, the target application page is supporting an Android system, and the page component may be an Activity component of Android, which is a component for providing a User interaction UI (User Interface).
When the target application page is operated and opened by the user, the corresponding page component may be initialized, and in this embodiment, the initialization time of the page component may be determined by monitoring.
Step S2120, when the page component declares a function or method related to the wireless network access function in the initialization process, determining that the application function provided by the target application page includes the wireless network access function.
When the initialization opportunity of the page component is monitored and determined, the page component can be determined to declare the function or the method used in the initialization process, and when the page component declares the function or the method related to the wireless network access function in the initialization process, the application function provided by the target application page can be determined to comprise the wireless network access function.
In this example, the page component may be an Activity component of Android, and when the Activity component is initialized, declares methods such as "onCreate", "onAttachedToWindow", and the like, it may be determined that the target application page provides a wireless network access function.
After step S2100, the flow proceeds to:
step S2200 is that, when the application function provided by the target application page includes a wireless network access function, the accessible wireless network is scanned and acquired, and a corresponding wireless network list is acquired and stored in the local cache.
The wireless network list includes identification information of a plurality of wireless networks available for access. The identification information is used to uniquely identify the corresponding wireless network, and may be a network ID or a network name of the wireless network.
The list of wireless networks may also include other information such as the wireless signal strength of each wireless network available for access.
The local cache is a memory allocated to the target application page by the operating system of the electronic device in this embodiment, and is automatically released when the target application page is destroyed, so that the memory is not continuously occupied. The acquired wireless network list is stored in the local cache, so that the wireless network list can be prevented from continuously occupying the memory, and the use efficiency of the memory is improved.
When the target application page comprises a wireless network access function, a wireless network which can be accessed is scanned and obtained, and a corresponding wireless network list is stored in a local cache, so that the wireless network list can be directly read and displayed to a user to select a wireless network to be accessed when the user starts the wireless network access function in combination with the subsequent steps, and the speed of obtaining the wireless network by the user is improved.
In one example, step S2200 may be as shown in FIG. 4, including steps S2210-S2220.
Step S2210, starting an asynchronous thread to call a corresponding application interface for scanning a wireless network, and executing a step of scanning an accessible wireless network.
An asynchronous thread is a child thread that is distinct from the main thread running the target application page.
The wireless network which can be accessed can be asynchronously scanned by starting the asynchronous thread to call the corresponding application interface for scanning the wireless network, so that the phenomenon that the main thread runs because of excessive processing resource consumption in the process of scanning the wireless network is avoided, and page blockage is reduced.
In this example, the application interface for scanning for wireless networks may be provided by the operating system supported by the target application page. For example, the target Application page supports an Android operating system, the wireless network is a Wifi network, and the step of scanning for an accessible wireless network may be performed by calling "WifiManager # startScan" in an API (Application Programming Interface) provided by the Android system.
Step S2220, monitors broadcast signals related to scanning wireless networks, obtains the latest wireless network list, and stores the latest wireless network list in the local cache.
After the accessible wireless network is scanned by calling the corresponding application interface, the corresponding wireless network scanning result can be determined by monitoring the broadcast signal related to the scanned wireless network, and the latest wireless network list is obtained and stored in the local cache.
For example, scanning an accessible wireless network is performed by calling "WifiManager # startScan" in an API provided by the Android system, the Android system broadcasts "wifimanager.scan _ RESULTS _ AVAILABLE _ ACTION" to remind a user of a change in a wireless network list of the wifi network when the change in the wireless network list of the wifi network is found by scanning, and by monitoring the system broadcast, after receiving the system broadcast, the latest wireless network list is obtained by "wifimanager.scan _ RESULTS _ AVAILABLE _ ACTION" and is stored in a local cache.
One example of the implementation of step S2200 has been described above.
In this embodiment, the execution manner of step S2200 may be set according to the scene of the specific application or the application requirement. For example, in some application scenarios, it may be set that step S2200 is performed only once after the user opens the target application page, for the purpose of saving processing resources or power.
In other application scenarios, the user may start the wireless network access function of the target application page at a longer time interval after opening the target application page, and only once execute step S2200, the obtained wireless network list may lose timeliness, and the requirement of the user for quickly accessing the wireless network cannot be met.
Therefore, in one example, step S2200 may be performed according to a preset scanning period.
The scanning period can be set according to a specific application scene or application requirements.
Alternatively, the scanning period may be dynamically adjusted according to the specific wireless network scanning result.
For example, the wireless network list obtained by scanning in the latest scanning period is compared with the wireless network list stored in the local cache, and if the identification information of the wireless networks included in the two wireless network lists is not changed, the duration of the scanning period is prolonged, and a new scanning period is obtained by updating.
The wireless network lists stored in the local cache are obtained by scanning in the last scanning period, the wireless network lists obtained in the previous and next scanning periods are compared, if the identification information of the wireless networks in the two wireless network lists is not changed, the wireless network lists obtained in the previous and next scanning periods are the same, and the wireless network environment where the user is located between the two scanning periods can be estimated to be unchanged (for example, the position where the user is located is unchanged), so that the duration of the scanning period can be prolonged to obtain a new scanning period, the scanning is performed based on the scanning period with longer duration, and the processing resources or the electric quantity can be effectively saved on the basis of ensuring the timeliness of the wireless network lists.
The specific extended duration may be set according to the actual application requirement, and is not limited in this example.
For another example, when the wireless network for access cannot be acquired in the last scanning period, the duration of the scanning period is extended, and a new scanning period is obtained by updating.
Scanning fails to acquire an accessible wireless network, which means that wireless network signals are too weak or no wireless network exists in the environment where the user is located, and if continuous scanning acquisition is performed, processing resources or electric quantity waste may be caused, so that the duration of a scanning period can be prolonged to obtain a new scanning period, scanning is performed based on the longer-duration scanning period, and the processing resources or the electric quantity are effectively saved.
In an example, step S2200 is executed according to a preset scanning period, and the step of specifically acquiring the wireless network list may include, as shown in fig. 5: steps S2201-S2202.
Step S2201, comparing the wireless network list scanned and acquired in the latest scanning period with the wireless network list stored in the local cache, to obtain the wireless signal change information of the plurality of wireless networks included in the latest acquired wireless network list.
The wireless network list stored in the local cache is obtained by scanning in the last scanning period, and the wireless network lists obtained in the previous and next scanning periods are compared to obtain the wireless signal change information of a plurality of wireless networks included in the wireless network list which is obtained newly.
The wireless signal change information is information related to a wireless signal change of the corresponding wireless network. The wireless signal change information includes at least the strength of the wireless signal, the type of change in the strength of the wireless signal, and the magnitude of change in the wireless signal.
The wireless signal strength change types comprise wireless signal enhancement and wireless signal weakening.
It should be understood that, if a wireless network does not exist in the wireless network list scanned and acquired in the last scanning period appears in the latest wireless network list, the type of the change of the wireless signal strength of the corresponding wireless network belongs to wireless signal enhancement, and the change amplitude of the corresponding wireless signal is the wireless signal strength of the wireless network.
Step S2202, according to the wireless signal change information, selects a wireless network meeting a preset number of wireless signal strength changes meeting a selection rule from the newly acquired wireless network list, generates a corresponding wireless network list, and stores the wireless network list in a local cache.
The selection rule is that the wireless signal intensity of the corresponding wireless network is greater than a preset intensity threshold value and the enhanced amplitude of the wireless signal intensity exceeds a preset amplitude threshold value.
In this example, the preset number, the intensity threshold, and the amplitude threshold may be set according to a specific application scenario or an application requirement.
In this example, a wireless network with a wireless signal slightly greater than a preset intensity threshold and a wireless signal intensity enhancing amplitude greater than the preset amplitude threshold is selected, and a wireless network with a weakened wireless signal intensity between two scanning periods can be eliminated, so that only a wireless network with a stronger wireless signal intensity and a stronger wireless signal intensity with a reinforcing trend is reserved in a wireless network list, and after a user starts a wireless network function, the wireless network with the stronger wireless signal intensity and better network quality can be preferentially provided for the user, thereby improving the wireless network access efficiency, avoiding the wireless network list from including more redundant wireless networks, occupying local cache, and reducing the cache utilization efficiency.
In this embodiment, the step of acquiring the wireless network list may further include:
and performing descending sorting on the wireless networks which are obtained by scanning and can be accessed according to the wireless signal intensity, selecting the wireless networks which are in the front of the sorting and accord with the preset number, generating a corresponding wireless network list and storing the wireless network list in a local cache.
The preset number can be set according to a specific application scene or application requirements. The wireless networks which accord with the preset number and are in the wireless signal strength sequence before are selected to generate the corresponding wireless network list, so that the wireless networks with strong wireless signal strength and good network quality can be preferentially provided for the user after the user starts the wireless network function, the wireless network access efficiency is improved, the phenomenon that the wireless network list comprises more redundant wireless networks, the local cache is occupied can be avoided, and the cache utilization efficiency is reduced.
After step S2200, the process proceeds to:
step S2300, receiving an enabling operation of the user on the wireless network access function of the target application page, and reading the wireless network list from the local cache to display the wireless network list, so that the user can select a target wireless network to access the target wireless network.
The operation of enabling the wireless network access function is an operation that a user triggers the wireless network access function of the target application page to be enabled through preset clicking, sliding and other operations, for example, an operation of sliding a button of the wireless network access function in the target application page to a specified page position.
When the user starts the wireless network access function, the wireless network list is directly read from the local cache and displayed to the user so that the user can select a wireless network to be accessed, the user does not need to wait for scanning to obtain the wireless network list, the wireless network amount can be directly selected and counted, and the speed of obtaining the wireless network by the user is improved.
In practical application, if a user is in an environment where the wireless signal strength of a wireless network is weak or no wireless network exists after opening a target application page, the corresponding wireless network list cannot be acquired, so that the user cannot directly read the corresponding wireless network list from a local cache when starting a wireless network access function. For such an application scenario, the method provided in this embodiment further includes:
when the wireless network list cannot be read from the local cache, the step of scanning the accessible wireless networks is executed to acquire the corresponding wireless network list.
And when the corresponding wireless network list cannot be directly read from the local cache, the step of scanning the accessible wireless network is executed again to obtain the corresponding wireless network list, so that the user can still obtain the wireless network list to select the wireless network access, and the user experience is ensured.
