Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Basic thought of the present invention is: by application layer, ccf layer and the Drive Layer of Audio (audio frequency) system in the Android platform being made amendment and perfect, support the more voice channel function on the Android platform to be implemented in.So-called more voice passage is meant that a portable terminal holds two or more communication modules simultaneously, and a plurality of communication modules are connected with sound card, and support the speech data input and output on each road.
Fig. 1 shows and the present invention is based on the system configuration that the Android platform is supported the more voice passage, described system 100 is applied to the portable terminal that multimode/dual-mode handset etc. comprises a plurality of communication modules, this system 100 mainly is divided into application (Java) layer, ccf layer and Drive Layer according to the Android platform architecture, and comprise that mainly module has: be positioned at application layer voice management module 10, be positioned at the Audio framework administration module 20 of ccf layer and be positioned at the Audio driver module 30 of Drive Layer, wherein:
Audio framework administration module 20 is used to manage the Audio system mode, according to current Audio system mode current speech pattern is set, and to calling the interface of Drive Layer down, to call the Audio driver module 30 of Drive Layer.
Preferably, the application layer of native system 100 also comprises communications applications module 40, is used for calling voice management module 10 before each voice communication, and communications applications module 40 is provided with current Audio system mode according to the communication pattern of current reality.
As shown in Figure 1, in the Audio of Android platform system, had more an Audio ccf layer, the Audio system is provided to the Java application layer with interface function, and the Audio ccf layer provides JNI interface (JavaNative Interface, Java local interface) 50 to give the Java application layer.Application program all operates in the Java application layer, and each module of Java application layer can call each module of Audio ccf layer by JNI interface 50, and for example voice management module 10 is called Audio framework administration module 20 by JNI interface 50.The Audio ccf layer is specifically designed to the various mode switch management of processed voice, and to top Java application layer complete closed, the Java application layer is without the Managing speech processing logic, as long as call by different needs; Same to following Drive Layer, as long as actual, also need not manage logical process to the calling separately of a plurality of modules.This Audio system not only structure is analysed clearly, the follow-up function expansion of being more convenient for.
Fig. 2 shows and the present invention is based on the method flow that the Android platform is supported the more voice passage, and it can realize that described method comprises that step has by system shown in Figure 1 100:
Step S201, a plurality of voice channels of voice management module 10 definition of application layer, the speech pattern that the corresponding respectively different communication module of each voice channel is adopted.The GSM speech pattern of the CDMA speech pattern of cdma communication module and gsm communication module in the mode mobile terminal for example.
Step S202, voice management module 10 is judged current Audio system mode, and the Audio framework administration module 20 of invoke block rack-layer.Wherein, ccf layer provides JNI interface 50 to application layer, and voice management module 10 is called Audio framework administration module 20 by Java local interface 50 and got final product.
Step S203, Audio framework administration module 20 management Audio system modes, and current speech pattern is set according to current Audio system mode, and the Audio driver module 30 that calls Drive Layer is to realize the switching of various speech patterns.
Step S204, Audio driver module 30 switch corresponding voice channel to realize voice communication according to current speech pattern.Audio driver module 30 becomes the voice channel of respective communication module to realize received audio signal according to the different phonetic mode switch, send voice signal.
By above-mentioned method based on Android platform support more voice passage, the present invention can effectively solve the problem of supporting the multi-path voice operate as normal under the Android platform.
Fig. 3 shows the preferred method flow of supporting the more voice passage of invention, and present embodiment is applied to comprise the mode mobile terminal of cdma communication module and gsm communication module, and it can realize that by system 100 as shown in Figure 1 this method comprises that specifically step is as follows:
Step S301, voice management module 10 definition two voice channels---the CDMA voice channel and the GSM voice channels of application layer, the CDMA speech pattern that the corresponding cdma communication module of CDMA voice channel adopts, the GSM speech pattern that the corresponding gsm communication module of GSM voice channel adopts.
Step S302, the communications applications module 40 of application layer was called the voice management module 10 of this layer before each voice communication, according to current communication pattern current Audio system mode is set.That is to say that communications applications module 40 decision Audio system modes are because have only communications applications module 40 to know that just current communication module of carrying out voice communication is cdma communication module or gsm communication module.
Step S303, voice management module 10 is judged current Audio system mode, and passes through the Audio framework administration module 20 of JNI interface 50 invoke block rack-layers.
Step S304, Audio framework administration module 20 receive and also handle the order that application layer is called, and according to current Audio system mode setting and preserve current speech pattern, and call the Audio driver module 30 of Drive Layer.Here, Audio framework administration module 20 is converted to the discernible classification of Drive Layer with correlation type, to call Audio driver module 30.
Step S305, the order that Audio driver module 30 receives and the processing block rack-layer is called according to current speech pattern, is switched corresponding voice channel, to connect different hardware module work.
Step S306, if current be the CDMA speech pattern, then call the cdma communication module with phonetic entry, output to sound card and handle.
Step S307, if current be the GSM speech pattern, then call the gsm communication module with phonetic entry, output to sound card and handle.
In sum, the present invention is by making amendment to application layer, ccf layer and the Drive Layer of Audio system in the Android platform and perfect, promptly at a plurality of voice channels of voice management module definition of application layer and judge the Audio system mode, Audio framework administration module by ccf layer is provided with current speech pattern according to the Audio system mode, and the Audio driver module that calls Drive Layer switches corresponding voice channel to realize voice communication.Whereby, the present invention can support the more voice channel function on the Android platform, thereby realizes multi-path voice operate as normal on the Android platform of multimode/mode mobile terminal.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
