Embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:
Expand the method that Android system resource loads, it is characterized in that: specifically comprise following steps:
As shown in Figure 1, step 1, monitors the state change of SIM cards of mobile phones;
Step 2, when SIM card state changes, obtains the operator's informaiton of SIM card, loads different mapping relations tables, obtain mapping result according to mapping relations table according to operator's informaiton, by mapping result stored in system property and then terminate to map;
Step 3, before Android system loads resource, the bag name of MCC, MNC in acquisition device configuration information and the program of current operation, and then MCC, MNC of acquisition are saved in temporary variable;
Step 4, the bag name obtaining program according to step 3 judges that current program is the need of mapping;
Step 4.1: if desired carry out mapping process, takes out MCC, MNC after mapping from system property, and then MCC, the MNC after mapping is replaced MCC and MNC original in system configuration information respectively;
Step 4.2: carry out mapping process if do not need, the value of mapping is replaced the value of the original MNC of device configuration information;
Step 5: after Android system loading resource completes, the value of original MCC and MNC is replaced.
Wherein, in step 2, adopt the mapping mode that SPN maps or GID maps, in step 4, need the bag list of file names of mapping defined in code or MXL.
For solving the problem, in the application, providing a kind of method expanding Android system resource load mechanism, the resource in above situation being loaded and loads the same with primary resource, no longer need in code, do loaded down with trivial details judgement and load resource.
The resource load mechanism of Android system supports MCC, the loading scheme of MNC, the mode that expansion adopts MNC mapping is loaded to primary resource, such as, mobile phone inserts the card of operator of Deutsche Telecom, system default preferentially loads the resource of values-mcc204-mnc16 in resource file folder, but, there is multiple sub-brand name in this operator, the value of the MCCMNC of all sub-brand names is all 20416, in this case resource mapping method is adopted, because the title of MNC confirms on market, consider the value by not having the MNC used, be mapped as the SPN of some correspondences, such as, by MNC (999) to should the sub-brand name 1 (BenNL) of operator, by MNC (998) to should operator sub-brand name 2 (T-MobileNL) like this, if mobile phone inserts the SIM card of this sub-brand name 1 (BenNL), system preferentially will go the resource under loading values-mcc204-mnc999 file, if mobile phone inserts the SIM card of this sub-brand name 2 (T-MobileNL), system preferentially will go the resource under loading values-mcc204-mnc998 file.
Wherein corresponding relation, we pre-define in xml or in code, need the application according to SIM card customization resource only to need to create corresponding MCC-MNC file according to corresponding relation under resource file folder.
Expansion for resource load mechanism is divided into two part: MNC to map and resource loads.
MNC demapping section technology realizes:
Application program registration is to the monitoring of SIM card state change; When SIM card state changes, receive the notice of state change, obtain the MCC of new SIM card, the attributes such as MNC, SPN and GID; According to MCC, the value of MNC uniquely can determine an operator, then judges whether to need to map according to operator, and the mode mapped (SPN maps or GID maps), if need to map, then load different mapping relations tables according to operator; According to the MCC of SIM card, MNC, SPN and GID, obtain the value after mapping in mapping relations table.By the value after mapping stored in system property.
Resource loading section technology realizes:
Resource loading section needs to load in the flow process of resource at Android system to modify.Known Android system also can specify the configuration information of current device when carrying out Gains resources according to the ID of resource, the configuration information of current device is kept in the variable of a structure, which describe all configuration informations of equipment, certainly also comprise MCC, the value of MNC.In the process loading resource, the resource of loading can compare with device configuration information, the resource of being mated most.So we carried out mapping process to the MNC of configuration information before resource loads, the function of resource mapping so just can be realized.
Before loading resource, obtain the MCC in device configuration information, the bag name of the program of MNC and current operation.By the MCC obtained, MNC is saved in variable, stores temporarily.Judge that current program is the need of mapping according to bag name.Need in the in xml defined or code of bag list of file names mapped.Initialized time, carry out loading or initialization according to operator.
If need to carry out mapping process, from system property, take out the value of the mapping that demapping section is preserved, as 999.The value of mapping is replaced the value of the original MNC of device configuration information, such as, replace with 999 by 01.System is searched according to the value of new MCC, MNC and is loaded resource.After system loads resource completes, the value of original MCC and MNC is replaced, like this can not other place of influential system.
Above embodiment is only and technological thought of the present invention is described, can not limit protection scope of the present invention with this, and every technological thought proposed according to the present invention, any change that technical scheme basis is done, all falls within scope.By reference to the accompanying drawings embodiments of the present invention are explained in detail above, but the present invention is not limited to above-mentioned embodiment, in the ken that those of ordinary skill in the art possess, makes a variety of changes under can also or else departing from the prerequisite of present inventive concept.
