Fig. 1 is a flow chart of a method for setting a country code based on an Android system according to an embodiment of the present application, and the method includes step S101, step S102 and step S103.

For example, as shown in Figure 1, through the upper and lower half of the writing method, write to the attribute service of the init part, initialize to the application category of the frameworks, and go to the desktop category of the launcher app to complete the entire country code setting process. The distinction between writing in the first half of the statement and writing in the second half is for different distinctions between flashing and starting. The writing in the first half is written to a specific location of the NV partition through the operation of the UI interface. This location cannot be erased by factory reset (master clear), and the country code initialized after factory restoration is restored. The second half of writing is to complete the setting of the country code through the firmware upgrade after the command is written.

In step S101, the target country code is divided into an upper half and a lower half, and the target country code is written into the attribute service of the init part of the Android system by writing the upper and lower halves respectively.

In some embodiments, the first half of the target country code is applied to the after-sales end; wherein, the writing process of the first half of the target country code includes: after the user enters the corresponding password in the search bar on the setting page, The page switches to the country code setting page of the tooling application; the user selects the corresponding country code, operator logo bit and OEM custom bit, and combines to obtain the upper half of the target country code; the upper half of the target country code The segment is written to the corresponding location of the NV partition.

For example, as shown in Fig. 2, the writing in the first half is mainly performed in the application of the mold. This part is mainly used in the after-sales end. The reason for the design of this part is that the machine is not easy to use and write instructions, and it is suitable for the operation of non-technical personnel to switch country codes. The working process is as follows: After entering the password ##XXX# (or similar password) in the search bar of the setting page (as shown in B1 in Figure 2), the page switches to the country code switching page of the tooling application (B2 in Figure 2 As shown), set the country code on the country code setting page (as shown in B2 in Figure 2), first select the country code of the shipment (for example, the UK country code is GB), and then select the operator flag, if not selected, set X ; Select the OEM engraved position, if not selected then set X; after the selection, click the OK button to write GBXX (as shown in B3 in Figure 2) to a certain segment of the NV partition (the ones that cannot be cleared by the main clearing operation of restoring the factory) Place), as shown in B4 in Figure 2; after performing the above operations, perform the actions of main clearing and booting, as shown in B5 in Figure 2.

In some embodiments, the writing process of the second half of the target country code includes: receiving an instruction parameter about writing the second half of the country code, and setting the executable program of the country code NV partition according to the instruction parameter, and The second half of the target country code is written into the corresponding position of the NV partition.

For example, as shown in Figure 3, the page with no operation written in the second half is written in the factory version (the factory version has a relatively high Root authority, which is the prerequisite for setting the execution of the country code executable program), Write the country code parameters into a certain segment of the NV partition at one time through the command. Its working process is as follows: first, the factory version shown as C1 in Figure 3 receives command parameters, such as adb shell lc_nv_ram write 60 8GBXX, the meaning of this parameter is: run the self-programmable program that sets the country code nv partition as lc_nv_ram, execute Write operation, write the national code parameters of GBXX to a certain segment or partition of the nv partition in the nv partition 60 segment offset 8 bits (as shown in C3 in Figure 3), and the flash machine is to be operated (as shown in C4 in Figure 3) Flash the machine into the user version and complete the writing of the country code.

Step S102, initialize the Android system, and run the application categories of the frameworks part of the Android system.

In some embodiments, the step S102 includes: initializing the Android system, reading parameters from the corresponding position of the NV partition, using the bootloader part to generate the parameter ro.boot.countrycode=GBXX, and setting the ro.boot.countrycode = GBXX is passed to the init properties service; zprojects are set up, different compilation projects in the zprojects are determined according to hardware OD requirements, a macro variable is added to the mk file for each different compilation project, and the mk file is added The project_xx_xx is passed to the init propertiesservice.

For example, after the steps shown in B4 in FIG. 2 and C3 in FIG. 3 , that is, after the steps shown in D4 in FIG. 4 , the reading work for the first boot is performed. Next, as shown in Figure 4, its workflow is to generate Androidboot.countrycode=GBXX in the bootloader after D2 reads the parameters of the partition of D4. Its purpose is to generate a parameter ro.boot.countrycode=GBXX for D6 to use. D6 reads two important parameters, one of which is the compiled macro produced by the mk file to control the configuration information of the device through the macro, such as the distinction between the device name of the wifi version and the LTE version; the mk file (as shown in D3 in Figure 4) is Obtained through D1; D1 is the zprojects set up to add compiled projects. There are different compiled projects in zprojects, which are made according to the hardware OD requirements. Each different project will add a macro variable to the mk file; D6 will Obtain the macro variables in the mk file, and distinguish the hardware OD requirements in the init program; D6 has obtained two parts of the variables, one is the ro.boot.countrycode generated by the bootloader (as shown in D2 in Figure 4), and the other One is the macro variable of the project_wifi or project_lte version of the mk file (as shown in D3 in Figure 4); D6 needs to be added according to the default attributes of the variables passed from D2 and D3.

The principle of part D1 in Figure 4 is shown in Figure 5. Its functions are mainly concentrated in the fact that there are many compiled builds in zprojects, such as compiling project_wifi, project_lte, project_wifi_audio, project_lte_audio, etc. These builds form a corresponding compilation macro to init during the compilation process. In the mk file of the module, a project_xx_xx is finally provided.

The principle of the D2 part in Figure 4 is shown in Figure 6. First, read the written parameters from a certain section of the nv partition or a certain partition; after the bootloader part obtains the parameter, it will judge whether the parameter is empty; if it is empty If so, this part will give a default country code parameter USXX; if it is not empty, set the cmdline value android.countrycode=GBXX/USXX (default) according to the read parameter; the final result is ro.boot.counrtycode = USXX.

In some embodiments, the init properties service receives the ro.boot.countrycode=GBXX and the project_xx_xx, and reads the configuration file of the country code configuration list, checks the country code to determine whether it contains the country of shipment, and determines The attribute information that needs to be modified.

For example, the principle of the D6 part in Fig. 4 is shown in Fig. 7, and the D1 part (as shown in Fig. 5) and the D2 part (as shown in Fig. 6) in Fig. 4 respectively generate parameters as the D6 part (as shown in Fig. 7) Used. Part D6 will receive two parameters generated by parts D1 and D2: ro.boot.countrycode=GBXX and project_xx_xx; in addition, the configuration file of the country code configuration list shown in E7 in Figure 7 must be read. After obtaining the parameters shown in E4 in Figure 7, the D6 part will first disassemble the bits and obtain the country to generate ro.product.google.3bitX, and the two ro.odm.setf.4bitX shown in E6 and E7 in Figure 7 attribute, these two attributes will be distinguished by the upper layer. After reading config_country_list.xml in Figure 7 (as shown in E3 in Figure 7), it will check whether the country code obtained by reading E4 contains the country of shipment, so as to obtain E8. This part mainly sets the language and E9 important system properties. By obtaining the country code of E4, the compilation parameters of E2 and the query of E12 country code of E11, it is determined to modify important authentication attributes (as shown in E10 in Figure 7).

The principle of part D7 in Figure 4 is shown in Figure 8. The role of adding this part is to solve the authentication problem of VTS and GSI. The execution program of this part must be placed in the vendor partition instead of the system partition. Among them, the method shown in F1 in Figure 8 and the method shown in E12 in Figure 7 are the same method, the method shown in F5 in Figure 8 and the method shown in E4 in Figure 7 are the same parameters, and the country code shown in F4 in Figure 8 The determiner obtains the parameters shown in Figure 5 and calls the country code required by Google shown in F1 in Figure 8, and generates a triggerable attribute after the judgment processing to trigger the processing shown in F3 in Figure 8, and finally configures a suitable The fingerprint, this fingerprint is used for the test report of VTS and GSI.

In some embodiments, the step S102 includes: according to the ro.boot.countrycode=GBXX, determine whether the obtained country code needs to add or remove the corresponding feature; through the customized package managerservice, obtain the corresponding app Configuration list, to determine whether the app configuration list needs to be added or removed.

For example, as shown in Figure 9, the main role of the framework part is to classify the apk and modify the feature. The main acquisition parameter of this part is ro.product.countrycode=GB in FIG. 7 (shown as G6 in FIG. 9 ), and this parameter is used for two channels. The first path determines whether to add or remove the corresponding feature in the obtained country through the consistent judgment shown in G5 in Figure 9 and F1 in Figure 8, and finally obtain a feature suitable for the GB country code. The second path needs to go through the customized PMS (package manager service) shown in Figure 9 G2, G2 needs to obtain the app configuration list of G3 (the list records in detail the apps that need to be supported under a certain country code and must be removed app), determine whether the app needs to be loaded or removed through the app loading judgment in G2, and finally obtain an adapted app list suitable for the GB country code (as shown in G1 in Figure 9).

Step S103, run the desktop category of the launcher app part of the Android system, and complete the setting of the target country code.

In some embodiments, the step S103 includes: after adapting the country code to the corresponding app configuration list, obtaining the ro.boot.countrycode, and using the desktop layout selector of the launcher app part to determine the corresponding desktop configuration .

For example, the processing of the launcher app is shown in Figure 10. The development of this part is mainly due to the different initial desktop layouts required by each country. After obtaining the remaining app list after country code adaptation in the framework (as shown in H1 in Figure 10), then obtain ro.product.countrycode as shown in E9 in Figure 7 (as shown in H5 in Figure 10), Load the desktop list database Launcherprovider in H2 through the desktop layout selector in the launcher app (as shown in H3 in Figure 10), and finally obtain a suitable desktop layout (as shown in H4 in Figure 10).

The distinction between writing in the first half of the statement and writing in the second half is for different distinctions between flashing and starting. The writing in the first half is written to a specific location of the NV partition through the operation of the UI interface. This location cannot be erased by factory reset (master clear), and the country code initialized after factory restoration is restored. The second half of writing is to complete the setting of the country code through the firmware upgrade after the command is written.

The first module 111 divides the target country code into an upper half and a lower half, and writes the target country code into the attribute service of the init part of the Android system by writing the upper and lower halves respectively.
