Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to examples and accompanying drawings, and the exemplary embodiments and descriptions thereof are only used for explaining the present invention and are not meant to limit the present invention.
Indicated in the examples below:
connection opportunity triggering: refers to the time when the application needs to connect with WiFi at any time;
WiFi: representing wireless communication 2.4G or 5G hot spot broadcasting;
WLAN state: the switching process of the state is fixed as the following two conditions:
open- > close;
closed- > open-medium- > closed.
Example 1:
as shown in fig. 1-2, the present invention includes a method for WLAN automatic WiFi connection of a mobile terminal, comprising the steps of:
s1: sequentially setting a closing state, an opening state and an opening state according to the WLAN state advancing sequence of the mobile terminal, and checking the state of the WLAN of the current mobile terminal;
s2: starting a corresponding thread according to the state of the WLAN of the current mobile terminal, circularly detecting, and directly entering WiFi connection flow processing to connect designated WiFi if the WLAN of the current mobile terminal is in the started state; and if the WLAN of the current mobile terminal is not in the started state, sequentially entering the next state, starting a corresponding thread, circularly detecting until the WLAN of the current mobile terminal is in the started state, entering WiFi connection flow processing, and connecting the specified WiFi. The corresponding threads and the loop detection of each state of the WLAN work independently without mutual influence. One or more state threads and loop detection work may be performed simultaneously.
The reasons for the failure of the WLAN to connect to the WiFi are various, and may be errors occurring in the process of opening the WLAN or in the process of connecting to the WiFi, and there is no feasible method for solving the errors occurring in the process of opening the WLAN at present. In the prior art, when a WLAN api is called to be opened, a user is required to give an application program an authority to open the WLAN due to a system security protection mechanism. For mobile phone manufacturers of different brands, mobile phone systems are different, the permission application frame for opening the WLAN is also set to be different, although the WLAN permission selection application frame is set on the mobile terminals of some manufacturers, the continuous operation of the application program APP on the same mobile terminal or different mobile terminals is not actually blocked, under the condition that a user does not operate the WLAN permission selection application frame, the continuous operation of the application program APP opens the WiFi connection WLAN, the WLAN is not opened at the moment, connection errors can occur, WiFi connection is stopped, the state is failed to return, and therefore the WiFi network cannot be connected to the designated and existing WiFi network automatically, the android system WLAN needs to be manually operated by the user repeatedly to be opened at the moment to be connected to the designated WiFi, the steps are complex, the success rate and the duration rate are not ideal. Because no matter what kind of brand's cell-phone, four kinds of states that WLAN locates are fixed unchangeable, this scheme is based on this principle, divide into four kinds with the state that WLAN locates, all set up corresponding thread to every state, carry out the cycle detection, and each thread independent work, each is not mutually influenced, only after WLAN has been opened the state, just continue to operate application APP on same mobile terminal or different mobile terminals, carry out wiFi and connect, avoid user's manual operation to open android system WLAN repeatedly, can realize the full automatic connection of wiFi. The method can realize full-automatic connection of designated WiFi for android mobile phones of any domestic manufacturer, and is good in compatibility, high in success rate and good in continuity.
Starting a corresponding thread according to the state of the WLAN of the current mobile terminal, circularly detecting, and directly entering WiFi connection flow processing if the WLAN of the current mobile terminal is in the started state; if the WLAN of the current mobile terminal is not in the started state, entering the next state in sequence, starting a corresponding thread, circularly detecting until the WLAN of the current mobile terminal is in the started state, and entering WiFi connection flow processing, wherein the specific implementation steps are as follows:
s21: if the WLAN state of the current mobile terminal is in the closing state, starting a thread, circularly detecting whether the WLAN state is in the closing state, and if the WLAN enters the closing state, exiting the circulation;
s22: if the WLAN state of the current mobile terminal is closed, starting a thread, calling android api to open the WLAN, circularly detecting whether the WLAN enters the open state, and if the WLAN enters the open state, exiting the circulation;
s23: if the WLAN state of the current mobile terminal is in the opening state, starting a thread, circularly detecting whether the WLAN state is in the opening state, and if the WLAN enters the opening state, exiting the circulation;
s24: and if the WLAN state of the current mobile terminal is started, entering WiFi connection flow processing to connect the appointed WiFi.
In the WLAN connection process, it may also occur that the WLAN is just opened, the system may actively connect to the last time or WiFi with high priority, so that at this time, when we go to connect to the designated WiFi, the system is switched by the system connection logic, at this time, the processing mode is to let the system connect to the WiFi with high priority, and when it is detected that the system is connected, a command is invoked to disconnect the WiFi that the system is connecting or has connected, and the designated WiFi is reconnected.
Therefore, the WiFi connection flow process, connecting the designated WiFi, adopts the following processing steps:
s241: if the WLAN of the current mobile terminal is connected to the designated WiFi, starting a loop detection thread and keeping the loop detection thread without entering subsequent operation;
s242: if the WiFi of the WLAN connection of the current mobile terminal is different from the designated WiFi, in order to detect whether the WLAN in the thread is closed by the user, checking whether the WLAN state of the mobile terminal is a closed state, starting the thread, and entering circular detection until the WLAN state is the closed state;
due to the fact that the WiFi connection is failed to be opened by calling the android api, the user may not agree with the request of the WLAN permission box, the WLAN permission selection application box is set on the mobile terminal of part of manufacturers, the continuous operation of the application program APP on the same mobile terminal or different mobile terminals is not blocked, and the state failure can be returned under the condition that the user does not operate the WLAN permission selection application box, so that the WiFi connection failure is caused. In order to eliminate the reason that the WiFi connection failure is not caused by setting a WLAN permission selection application box on a mobile terminal of a part of manufacturers but does not block the continuous operation of the application APP on the same mobile terminal or a different mobile terminal, the following operations are performed:
recording the current time t1, calling android api to open the WLAN, returning to the state, recording the time t2 at the moment, if t2-t1 is less than a fixed time (such as 1 second) and the returned state is WiFi connection failure, sending a message to inform a user of timely processing authority, agreeing to WLAN connection, entering a starting thread, circularly checking, detecting the WLAN state at an interval of a fixed time (which can be 100 milliseconds), if the WLAN state is changed into the opening state, checking whether WiFi information configuration to be connected exists in the system, if the WiFi information configuration exists, directly reading the configuration for use, connecting the designated WiFi, otherwise, creating the designated WiFi information configuration, reading the created configuration information again, if the content of the configuration information is wrong, starting the thread to circularly re-read the configuration, recording the time, and if the content of the configuration information is more than a certain time, indicating that the system has an unknown problem, exiting the connection and returning to the. If the content of the read configuration file is correct, connecting the designated WiFi; if the WLAN state is not the opening state, accumulating the fixed interval time, if the accumulated fixed interval time is larger than a set value (such as 15 seconds), returning to the connection failure and stopping all threads. Each cycle of each thread detects whether the WLAN state is abnormally switched and exits the stop if abnormally switched.
By monitoring the opening time of the WLAN of the android api, when the time interval is less than a fixed time such as 1 second, the WLAN connection WiFi failure is considered to be abnormal, because if the user does not agree to connect the WLAN and returns to the state to connect the WiFi failure, the opening time of the WLAN of the android api is necessarily greater than the fixed time such as 1 second. Therefore, when the WLAN status is not in the on state, the fixed interval time needs to be accumulated, when the fixed interval time exceeds a limit value (e.g. 15 seconds), no WLAN connection is performed, which means that the user does not approve the WLAN connection operation, and the connection failure returned at this time is the correct value, all threads can be stopped, and the user is waited to trigger the operation next time. By monitoring the opening time of the WLAN by the android api, the abnormal condition of connection failure caused by setting a WLAN permission selection application frame on the mobile terminals of part manufacturers but not blocking the continuous operation of the application program APP on the same mobile terminal or different mobile terminals is further eliminated, and the success rate and the continuity of full-automatic WiFi connection are further improved. In order to connect the designated WiFi, the designated WiFi configuration information is judged, WiFi information configuration is not carried out, connection is carried out, the fact that the connected designated WiFi is a network in existence is guaranteed, and reliability of automatic connection of the designated WiFi is further improved.
When the designated WiFi information configuration is created, a special thread is needed to be started, whether the ID attribute in the configuration information which is just created has a value (-1 represents no value) or not is checked, if the ID attribute does not have the value, the circulation detection is carried out, the WLAN state is detected, if the WLAN state is not started, a connection failure message is sent, and all threads are stopped; and if the WLAN state is started, reestablishing the WiFi information configuration file, waiting for 1 second, accumulating the establishing times after a system processes a response task, if the establishing times are equal to 5 times, indicating that the system has an unknown problem, sending a connection failure message, and stopping all threads.
If the ID has a value (not equal to-1), indicating that the creation is successful, exiting the cycle, re-detecting whether the WLAN state is started, if not, sending a connection failure message, and stopping all threads; if the WLAN is in an opened state, circularly detecting whether the WiFi automatically connected by the current system is successfully connected, if the connection is successful, disconnecting the connection, calling an android system command to connect the WiFi, sending a delay notice, controlling the total WiFi connection time not to be more than 20 seconds (or other interval time), if the total WiFi connection time is more than 20 seconds, directly returning to the connection failure, and stopping all threads; and if the connection fails, accumulating the time, entering the next cycle, if the accumulated time is equal to 5 seconds, directly jumping out of the cycle, calling an android system to connect WiFi, sending a delay notice, controlling the total WiFi connection time not to be more than 20 seconds (or other interval time), and if the total WiFi connection time is more than 20 seconds, directly returning to the connection failure and stopping all threads.
In order to detect whether WiFi is switched by a user in a thread, when the WLAN is in an opened state, delaying for 0.1 second, checking whether the current WiFi is connected completely in a logic way, and if not, entering the next cycle; and if so, sending a connection success message, starting an error detection thread and keeping continuing to circularly detect whether the WiFi is switched by the user in the thread.
Preferably, if the WLAN status of the current mobile terminal is in the off state, timeout detection is required, and if the WLAN status is not changed to the on state within a fixed time, an error is returned to terminate the WLAN on operation.
The arrangement further eliminates the situation of connection failure in the full-automatic WiFi connection, and further improves the accuracy of the full-automatic WiFi connection.
In order to facilitate the user to find the problem, follow-up operation is carried out, and after the WLAN starting operation is terminated, the user is prompted to the reason of the failure according to the state.
