The technical scheme adopted by the invention for overcoming the technical problems is as follows:
a wifi frequency conversion method of an android system comprises the following steps:
a) starting the android system;
b) starting a frequency conversion service of the installation system;
c) the android system detects whether the android system is started for the first time, if so, the step d) is executed, and if not, the step h) is executed;
d) after the android system runs the startup guide process, determining a country code according to the IP address;
e) matching and acquiring a value of a count _ code or a channel _ plan when wifi drive of the installation system is loaded according to the acquired wifi demand list of the country code;
f) reloading a wifi drive according to the obtained value of the count _ code or the channel _ plan, and triggering a self-defined setprpo ctl.start load _ wifi service in an rc script of the bottom layer of the android system by using the value of the ctl.start attribute of the wifi drive;
g) the android system runs normally;
h) the android system loads a wifi drive according to the attribute value set by the last startup;
h) and the android system is connected with the network through wifi, and then judges whether the current country code is consistent with the country code obtained when the android system is started last time according to the IP address, if so, the android system normally operates, and if not, the steps e) to g) are executed.
Further, in the step b), the frequency conversion service is that the installing system modifies a channel list supported in the wifi driver according to the wifi channel supported by the country where the IP is located, and the wifi channel in the channel list which is no longer supported is not scanned by the wifi driver.
Further, in the step d), the country name, the country code and the country region of the current IP are obtained in the corresponding API website by using the IP address.
The invention has the beneficial effects that: through the wifi frequency conversion, can obtain national information according to the IP that android device connects, then through the wifi drive of national information matching regulation to avoided carrying out the burning record of different mirror images to different countries, great each android device manufacturer of today of being convenient for globalizing carries out globalized sale.

FIG. 1 is a schematic flow chart of the method of the present invention.
Detailed Description
The invention is further described below with reference to fig. 1.
A wifi frequency conversion method of an android system comprises the following steps:
a) starting the android system.
b) And starting the frequency conversion service of the installation system.
c) And the android system detects whether the android system is started for the first time, if so, the step d) is executed, and if not, the step h) is executed.
d) And after the android system runs the starting guide process, determining a country code according to the IP address.
e) And matching and acquiring a count _ code or channel _ plan value when the wifi driver of the installation system is loaded according to the wifi demand list of the country of the acquired country code.
f) And reloading the wifi drive according to the obtained value of the count _ code or the channel _ plan, and triggering the self-defined setprpo ctl.start load _ wifi service in the rc script of the bottom layer of the android system by using the value of the ctl.start attribute of the wifi drive.
g) And the android system runs normally.
h) And the android system loads the wifi drive according to the attribute value set by the last startup.
h) And the android system is connected with the network through wifi, and then judges whether the current country code is consistent with the country code obtained when the android system is started last time according to the IP address, if so, the android system normally operates, and if not, the steps e) to g) are executed.
Through the wifi frequency conversion, can obtain national information according to the IP that android device connects, then through the wifi drive of national information matching regulation to avoided carrying out the burning record of different mirror images to different countries, great each android device manufacturer of today of being convenient for globalizing carries out globalized sale.
Further, in the step b), the frequency conversion service is that the installing system modifies a channel list supported in the wifi driver according to the wifi channel supported by the country where the IP is located, and the wifi channel in the channel list which is no longer supported is not scanned by the wifi driver.
Further, in the step d), the country name, the country code and the country region of the current IP are obtained in the corresponding API website by using the IP address.
The method has two key points, namely, the method is used for realizing the startup self-starting wifi frequency conversion service application on the application layer and realizing the network monitoring and attribute setting of the application layer. Secondly, realizing wifi frequency conversion on a system level, mainly realizing the reloading of the wifi drive and the parameter setting of the loading of the wifi drive, and mainly having two modification points, 1. 2. The wifi-driven reloading of network IP at a national change is what the system level needs to do.
On the application level: the method comprises the steps of monitoring starting broadcast or customized starting broadcast and then monitoring customized starting broadcast, and starting foreground service after monitoring broadcast (background service is easily killed after Android 8.0, and background service can be used before 8.0 version). And secondly, registering and sending the customized network broadcast in the service. And thirdly, monitoring the network broadcast of the system in the self-defined network broadcast, and acquiring the country name, the country code, the country region and the like of the current IP in a corresponding API website by using the current IP when the network is monitored. And fourthly, matching and acquiring parameters (the values of the count _ code or the channel _ plan) during wifi drive loading by using the obtained country information and the wifi demand lists of each country. Fifthly, reloading the wifi drive according to the obtained value of the count _ code or the channel _ plan, and triggering the self-defined service in the bottom rc script by using the value of the set ctl.start attribute: start load _ wifi.
On a system level: step one, modifying an rc script driven by a wifi during startup loading: (location: hardware/ampligic/wifi/configs/init _ rc/init. ampligic. wifi _ build _ rtl8822cs. rc) instmod 8822cs. ko rtw _ count _ code = { permanent. wifi. code }// rtw _ count _ code parameter represents country code information, and the latter attribute permanent. wifi. code represents the country code that ip gets stored. Secondly, adding a persistence attribute, storing a country code of a corresponding country, and loading a wifi driver to add a position: and (4) setting permission for the added attribute value after adding device/platform/product name/. mk, wherein the current attribute is a String type attribute, and the user group is a system. And thirdly, adding a frequency conversion service in the rc script, and adding a load _ wifi service in the device/platform/product name/init. Step four, adding the frequency conversion service and the script added above to cause a selinux permission problem and a modified position: according to the system/topolicy/, a loadWifi.te file is newly built according to the newly added service, and the reported authority problems are added until no selinux authority problem occurs.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
