Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The core idea of the invention is that the play mechanism of short audio of soundport of Android platform is not used, but the application layer is broken through to directly call high-fidelity audio play hardware to play the corresponding call prompt tone, so as to avoid the long call waiting time delay generated by the processing of soundport, thereby effectively shortening the call waiting time delay of the user after the terminal initiates group call or the right to speak seize to the server.
The method for playing the group call prompt tone realized by the embodiment of the invention mainly comprises the following steps:
after initiating group calling or speech right preemption to a server, if a corresponding speech right granting message is received from the server, a corresponding call prompt tone is played by using a high fidelity HIFI audio playing module through calling a hardware abstraction layer HAL interface in an application layer.
Here, after the terminal is granted the speaking right, the HAL interface is called through the broken layer, and the corresponding conversation prompt tone is played by using the high-fidelity HIFI audio playing module, so that the conversation waiting time delay after the user presses the PTT key can be effectively reduced, and the user experience is further improved.
Preferably, in order to effectively shorten the call waiting time of the user, the following method may be specifically adopted in this step to play the corresponding call alert tone by using the HIFI audio playing module by calling the HAL interface at the application layer:
step a1, after receiving the right-to-speak granting message, the group calling Application (APP) in the terminal calls a frameword interface to play the talking prompt tone.
The group call application is an application in the terminal responsible for group call initiation and processing.
Step a2, the FrameWork interface calls the HAL interface to play the call prompt tone according to the call of the group call application.
In this step, after the FrameWork interface is called by the group call application in step a1, the HAL interface is called to play the call alert tone.
Step a3, the HAL interface triggers the HIFI audio playing module to play the call prompt tone according to the call of the FrameWork interface.
In this step, after the HAL interface is called by the FrameWork interface in step a2, the HAL interface triggers audio hardware (i.e., a HIFI audio playing module) in the terminal to play the call prompt tone.
