In the present embodiment, the second unified approach according to obtain the primary striding course method of target mark and target it is primary across Proceeding method enter ginseng, the primary striding course method of corresponding target is determined from the second process.I.e. according to reflex mechanism from The primary striding course method of the target actually called is determined in two processes.
It is appreciated that combine discussing above, the first process is when the target of calling itself primary striding course method, real It is to call the primary striding course method of the target in the second process on border.
Further, according to the primary striding course method of the target determined obtain it is corresponding call data, and data will be called It is back to the first unified approach.
Step 208, the first unified approach will call data to be back to operation layer, and according to the first unified approach carry out with The process operation for calling data related.
In the present embodiment, the data of calling that the second unified approach is returned are back to operation layer by the first unified approach.Go forward side by side One step, carries out the process operation related to data are called according to the first unified approach.
It should be noted that the process operation for calling data related to this, comprising to calling data to process in itself, with And operate with the process for calling data that there is incidence relation.
Further, it is possible to be data buffer storage will to be called to be uniformly accessed in layer to first according to the first unified approach.Can also It is to be calculated according to the first unified approach and obtain the duration for calling data to be spent.Can also be carries out other and calls number Operate according to related process.The embodiment of the present invention is not limited to this.
It should be noted that the first process is used to represent the request process for initiating that striding course is called that the second process to be used for table Show the response process that response striding course is called.
Now illustrate and above-mentioned steps are illustrated.Such as, process A is responsible for showing what is be currently played on terminal interface Song title, process B are responsible for playing song, have one respectively and are uniformly accessed into layer, be uniformly accessed in layer in process A and process B It is both provided with unified approach, respectively unified approach a and unified approach b.Process A is accomplished by striding course calling process B The title of the song of broadcasting, then process A will call primary striding course method getSongName () of its own, enter Unified approach a being uniformly accessed in layer of journey A will generate striding course call request and be transmitted to process B, the system in process B One method b can obtain the title of the primary striding course method of the actual institute's request call of unified approach a according to striding course call request With enter ginseng, then according to title and enter that ginseng determines the actual institute's request call of unified approach a is primary striding course method getSongName().Then process B obtains the song title being currently played according to getSongName (), then by system The song title of broadcasting is back to unified approach a by one method b.Song title is back to operation layer and is sung by unified approach a The display that song name claims.Additionally, the process operation related to the song title can be carried out according to unified approach a, such as, by the song Name cache is uniformly accessed in layer to process A, or calculates time for this time calling the song title to be spent etc. process Operation.
In the present embodiment, layer is uniformly accessed into equivalent to one is increased in process, unification is set in layer is uniformly accessed into Method, completes while calling of primary striding course method by unified approach, it is also possible to carried out using the unified approach Other process operations related to data are called.New side is added without changing each primary striding course method one by one Method and function, improve the extensibility of striding course method.
As shown in figure 4, in one embodiment, generate striding course call request, by striding course call request to it is asked The step of asking corresponding second process of the primary striding course method of the target the called to be transmitted (step of abbreviation striding course call request Suddenly), comprise the following steps:
Step 402, according to the mark and the primary striding course method of target of the primary striding course method of target of institute's request call Enter ginseng generate the first striding course call request.
Step 404, when the data volume of the first striding course call request is more than preset data amount threshold value or when sending the When during one striding course call request, triggering generates transmitted data amount excessive exception error, the first unified approach is then by the The ginseng that enters of the mark and the primary striding course method of target of the primary striding course method of target in one striding course call request writes position In the file of disk.
In the present embodiment, mark and target of first unified approach according to the primary striding course method of target of institute's request call The ginseng that enters of primary striding course method generates the first striding course call request.
In one embodiment, pre-set a data-quantity threshold.The first striding course for being generated can be called The data volume of request is compared with preset data amount threshold value, when the data volume of the first striding course call request is more than preset data During amount threshold value, the first unified approach can be by the mark of the target in the first striding course call request primary striding course method and target The ginseng write that enters of primary striding course method is located in the file of disk.
Further, when the data volume of the first striding course call request is less than or equal to preset data amount threshold value, then by the The request of one striding course call operation is directly transmitted to the second process by Binder striding courses transmission means.
In another embodiment, can be that the first striding course call request for generating is transmitted by Binder striding courses Mode (being a kind of mode that striding course transmission is realized in Android system) is transmitted to the second process, when in transmission process In, triggering generates the excessive exception error of transmitted data amount, and (TTLE, Transact Too Large Exception are used Binder striding courses transmit during data volume excessive and caused communication mistake when the exception error dished out) when, the first system One method can be by the mark of the target in the first striding course call request primary striding course method and the primary striding course method of target Enter ginseng write positioned at disk file in.
Step 406, the first unified approach according to the store path of file generate the second striding course call request, by second across Process call request is sent to the second process corresponding with the primary striding course method of target.
Further, the first unified approach generates the second striding course call request according to the store path of file, and by second Striding course call request is sent to the second process corresponding with the primary striding course method of target.
In the present embodiment, the second of the second process is uniformly accessed into the second unified approach in layer according to striding course call request The mark and the primary striding course method of target for obtaining the primary striding course method of target enters the step of joining, including:Second process Second is uniformly accessed into the second unified approach in layer searches corresponding file according to the store path of file, and institute is read from file The mark and the primary striding course method of target of the primary striding course method of target of write enter the step of joining.
Specifically, the second unified approach that second in the second process is uniformly accessed in layer is receiving the second striding course tune During with asking, the store path of the file included in obtaining the second striding course call request, and according to the storage road of this document Search corresponding file in footpath.Further, the mark of the write primary striding course method of target is read from the file for finding With the primary striding course method of target enter ginseng.
In the present embodiment, by unified approach send striding course call request when, for data volume it is excessive first across Process call request, in taking the critical data write file for being wherein used for determine striding course method, this document path is passed Give the second process corresponding with the primary striding course method of target, it is to avoid data volume is excessive and the striding course communication that causes is lost Lose.Improve the success rate of striding course communication.
In one embodiment, before the step of generating striding course call request, also it is uniformly accessed into including detection first Whether be cached with layer it is corresponding with the primary striding course method of target of institute request call call data, if so, then direct access The data of calling of caching call data as corresponding with the primary striding course method of target, if it is not, then performing generation striding course again The step of call request.
In the present embodiment, data buffer storage can be called to the first unification by corresponding with the primary striding course method called In Access Layer.So, before striding course call request is generated, the first unified approach can detect that whether first be uniformly accessed in layer It is cached with and corresponding with the primary striding course method of target of institute request call calls data.
It is cached with corresponding with the primary striding course method of target when calling data in first is uniformly accessed into layer, then directly obtains The data of calling for taking caching call data as corresponding with the primary striding course method of the target that this calls.
When first be uniformly accessed in layer without caching is not corresponding with the primary striding course method of target call data when, then hold again The step of row generates striding course call request.
With reference to above-mentioned example, unified approach a in process A was understood in detection procedure A before striding course call request is generated Be uniformly accessed into layer in whether be cached with song title, if so, then obtain the song title of the caching as calling with this The corresponding song title of getSongName () method.If it is not, then generating striding course call request.
In the present embodiment, be able to can detect whether before striding course call request is generated to calling data to cache Having cached needs what is obtained to call data, if it has, then the direct access caching calls data, if it is not, regeneration Striding course call request.I.e. by calling the detection of the caching and caching of data, it is possible to reduce the number of times that striding course is called, from And resource is saved, and improve the efficiency for calling data acquisition.
As shown in figure 5, in one embodiment, before the step of generating striding course call request, also including caching inspection Step is surveyed, following steps are specifically included:
Whether step 502, detection first are cached with the primary striding course side of target with institute's request call in being uniformly accessed into layer Method is corresponding to call data.If so, step 504 is then entered, if it is not, then entering step 506.
Whether step 504, what detection was cached call data out of date.If so, step 506 is then entered, if it is not, then entering step Rapid 508.
Step 506, generates striding course call request.
Step 508, the data of calling for obtaining caching call data as corresponding with the primary striding course method of the target.
In the present embodiment, data buffer storage can be called to the first unification by corresponding with the primary striding course method called In Access Layer.So, before striding course call request is generated, the first unified approach can detect that whether first be uniformly accessed in layer It is cached with and corresponding with the primary striding course method of target of institute request call calls data.
Be cached with first is uniformly accessed into layer it is corresponding with the primary striding course method of target when calling data, then further Whether that detects the caching calls data out of date.Do not cache and the primary striding course method of target during layer is uniformly accessed into when first It is corresponding when calling data, then perform the step of generating striding course call request.
Specifically, data whether mistake can be called detect the caching by detecting that this calls the flag state of data Phase.
When the caching is when calling data out of date, then the step of generating striding course call request is performed.When the caching When calling data not out of date, then the data of calling for obtaining the caching call number as corresponding with the primary striding course method of the target According to.
Also in conjunction with above-mentioned example, unified approach a in process A before striding course call request is generated, can detect into In journey A be uniformly accessed into layer in whether be cached with song title, if so, then further detect the song title of caching whether mistake Phase, if it is not, then generating striding course call request.When the song title of caching is not out of date, then the song title for obtaining the caching is referred to as It is to call the corresponding song title of getSongName () method with this.When caching song title it is out of date, then generate across Process call request.
In the present embodiment, be able to can detect whether before striding course call request is generated to calling data to cache Having cached needs what is obtained to call data, if it has, whether that then further detects the caching calls data out of date, if non-mistake Phase, then the direct access caching call data, if expired, regenerate striding course call request.I.e. by calling data Caching and the detection for caching, it is possible to reduce the number of times that striding course is called, so as to save resource, improve and call data acquisition Efficiency.Additionally, the data of calling to caching carry out whether expired judgement, the accuracy of call result is further increased.
As shown in fig. 6, in one embodiment, the method also includes calling data mode to monitor step, specifically include with Lower step:
Step 602, the second unified approach are back to the more new state for calling data of the first process in monitoring the second process.
Step 604, when calling data to occur to update, the second process sends update notification to the first process.
In the present embodiment, the second process can be monitored by second method after data will be called to return to the first process In second process self EMS memory returned this call the more new state of data.
When listen to call data occur update when, the second process can send update notification to the first process.Specifically, may be used To send first unified approach of the update notification to the first process by the second unified approach.
Step 606, the first unified approach of the first process will be cached in first according to update notification and be uniformly accessed in layer It is corresponding to call data markers to be state out of date.
