Detailed ways

Please refer to the drawings, in which the same reference numerals represent the same components, and the principles of the present invention are exemplified by being implemented in a suitable computing environment. The following description is based on illustrated embodiments of the invention and should not be construed as limiting other embodiments of the invention not detailed herein.

It will be explained in detail below.

Please refer to FIG. 1. FIG. 1 is a schematic flowchart of a data transmission control method provided by an embodiment of the present invention. The process may include:

In step S101, when data transmission is performed with the audio playback device through the terminal application, if an instruction for instructing the application to perform version update is received, a first process is created.

It can be understood that, the execution body of the embodiment of the present invention may be a terminal device such as a smart phone and a tablet computer.

For example, when a mobile terminal transmits data to an audio playback device such as a WiFi (wireless fidelity) speaker through a dedicated terminal application, if the dedicated application needs to be updated, the mobile terminal will temporarily interrupt communication with the audio playback device. This will cause the audio playback device to be unable to continue acquiring data from the mobile terminal, that is, the flexibility of data transmission between the mobile terminal and the audio playback device is poor, which affects the playback effect.

In step S101 of the embodiment of the present invention, when the terminal performs data transmission with the audio playback device through the application, if the mobile terminal receives an instruction for instructing the application to perform version update, the mobile terminal may be triggered first to create a new process , the first process.

In step S102, a second process corresponding to the application is determined, and running time data of the second process is acquired.

For example, after the first process is newly created, the terminal may determine the second process corresponding to the application, and obtain the runtime data of the second process, that is, obtain the running data of the second process. It can be understood that the second process is the process corresponding to the application in the terminal for data transmission with the audio playback device at this time.

In step S103, the running time data of the second process is transmitted to the first process through inter-process communication.

For example, after acquiring the running time data of the second process, the terminal may transmit the running time data of the second process to the first process through inter-process communication.

It should be noted that inter-process communication (Inter-Process Communication) is a technology that can communicate data between different processes. For example, if the terminal is installed with an Android (Android) operating system, the terminal may use the AIDL (Android Interface Definition Language, Android Interface Definition Language) process communication technology to implement communication between different processes. For another example, in the Android operating system, a Messenger-based technology may also be used to implement cross-process communication, and so on. It should be understood that the examples herein do not constitute a limitation to the present invention.

In step S104, a data transmission connection between the terminal and the audio playback device is established based on the first process that obtains the running time data of the second process to respond to the data transmission request of the audio playback device.

For example, after the first process obtains the runtime data of the second process, the terminal may establish a data transmission connection with the audio playback device based on the current first process to respond to the data transmission request of the audio playback device.

It can be understood that the runtime data of the second process includes the relevant data of the data transmission connection established between the terminal and the audio playback device (through the application), so the runtime data of the second process is transmitted to the first process. After the process, the terminal can establish a data transmission connection with the audio playback device based on the first process. That is to say, after obtaining the running time data of the second process, the first process can take over the data transmission connection between the terminal and the audio playback device originally managed by the second process.

It can be understood that, in this embodiment, when an application that is being used for data transmission between the terminal and the audio playback device needs to be updated, a new process can be created by the terminal to take over the process corresponding to the application, and based on the new process , establish a data transmission connection between the terminal and the audio playback device to respond to the data transmission request of the audio playback device, so as to avoid the terminal and audio caused by the inability of the application to respond to the data transmission request of the audio playback device during version update. Data transmission between playback devices is interrupted, that is, the embodiment of the present invention can improve the flexibility of data transmission between the terminal and the audio playback device, and improve the playback effect.

Please refer to FIG. 2. FIG. 2 is another schematic flowchart of a data transmission control method provided by an embodiment of the present invention. The process may include:

In step S201, when the terminal performs data transmission with the audio playback device through the application, if an instruction for instructing the application to perform version update is received, the terminal creates a first process.

For example, in the process that the terminal establishes a data transmission connection with the audio playback device through a preset application and transmits the local audio data of the terminal to the audio playback device, if an instruction for instructing the application to update the version is received, Then the terminal can first create a new process, that is, the first process.

In step S202, the terminal determines the second process corresponding to the application, and acquires the running time data of the second process.

For example, after the first process is newly created, the terminal may determine the second process corresponding to the application, and obtain the runtime data of the second process. It can be understood that the second process is the process corresponding to the application in the terminal for data transmission with the audio playback device at this time.

In step S203, through inter-process communication, the terminal transmits the running time data of the second process to the first process.

For example, after acquiring the running time data of the second process, the terminal may transmit the running time data of the second process to the first process through inter-process communication.

It should be noted that inter-process communication is a technology that can communicate data between different processes. For example, if the terminal is installed with an Android operating system, the terminal may use the AIDL (Android Interface Definition Language, Android Interface Definition Language) process communication technology to implement communication between different processes. For another example, in the Android operating system, a Messenger-based technology may also be used to implement cross-process communication, and so on. It should be understood that the examples herein do not constitute a limitation to the present invention.

In step S204, the terminal establishes a data transmission connection with the audio playback device based on the first process that obtains the running time data of the second process to respond to the data transmission request of the audio playback device.

For example, after the first process obtains the runtime data of the second process, the terminal may establish a data transmission connection with the audio playback device based on the current first process to respond to the data transmission request of the audio playback device. For example, the first process transmits the local audio data saved in the terminal to the audio playback device for playback.

It can be understood that the runtime data of the second process includes the relevant data of the data transmission connection established between the terminal and the audio playback device (through the application), so the runtime data of the second process is transmitted to the first process. After the process, the terminal can establish a data transmission connection with the audio playback device based on the first process. That is to say, after obtaining the running time data of the second process, the first process can take over the data transmission connection between the terminal and the audio playback device originally managed by the second process.

In step S205, the terminal responds to the instruction for instructing the application to perform version update, and performs version update for the application.

For example, after the terminal establishes a data transmission connection with the audio playback device based on the first process that has obtained the running time data of the second process, the terminal may respond to the previously received instruction for instructing the application to update the version, And follow the instructions to update the version of the app.

It can be understood that in the process of updating the version of the application by the terminal, the first process responds to the data transmission request between the terminal and the audio playback device, and completes the data transmission, and the application will no longer respond to the audio playback device. data transfer request.

In step S206, after detecting that the version update of the application is completed, the terminal creates a third process corresponding to the application after the version update is completed.

For example, after detecting that the version update of the application has been completed, the terminal may restart the application, and create a third process corresponding to the application after the version update is completed.

In one embodiment, step S206 may include the following steps:

After detecting that the version update of the application is completed, detecting whether the first process is terminated;

If it is detected that the first process has not been terminated, the terminal creates a third process corresponding to the application after the version update is completed.

For example, after detecting that the version update of the application has been completed, the terminal may detect whether it still maintains a data transmission connection with the audio playback device through the first process, that is, the terminal detects whether the first process is terminated.

If the terminal detects that the first process has not been terminated, the terminal may restart the application and create a third process corresponding to the application whose version update is completed.

If the terminal detects that the first process is terminated, the terminal can perform other operations without restarting the application. For example, during the version update process of the application, the user interrupts the data transmission between the terminal and the audio playback device because the user no longer needs to play audio, that is, the first process for data transmission between the terminal and the audio playback device was terminated. Then, in this case, the terminal can perform other operations.

In step S207, the terminal acquires the running time data of the first process, and transmits the running time data of the first process to the third process through inter-process communication.

In step S208, the terminal establishes a data transmission connection with the audio playback device based on the third process that obtains the running time data of the first process to respond to the data transmission request of the audio playback device.

For example, steps S207 and S208 may include:

After creating the third process corresponding to the updated application, the terminal may acquire the running time data of the first process, and transmit the acquired running time data of the first process to the third process through inter-process communication.

Then, the terminal may establish a data transmission connection between the terminal and the audio playback device based on the third process that has obtained the running time data of the first process to respond to the data transmission request of the audio playback device.

That is to say, after detecting that the application has completed the version update, the terminal can create a third process corresponding to the application whose version update has been completed, and the third process can take over the connection between the terminal and the audio playback device previously established by the first process. data transfer connection in response to data transfer requests from audio playback devices. That is, after that, the third process will complete the data transmission between the terminal and the audio playback device. For example, the third process transmits the local audio data saved in the terminal to the audio playback device for playback.

In step S209, the terminal terminates the first process.

For example, after the third process takes over the data transmission connection between the terminal and the audio playback device established by the first process, the terminal may end the first process, that is, terminate the first process.

It can be understood that, in this embodiment, when an application that is being used for data transmission between the terminal and the audio playback device needs to be updated, a new process can be created by the terminal to take over the process corresponding to the application, and based on the new process , establish a data transmission connection between the terminal and the audio playback device to respond to the data transmission request of the audio playback device, so as to avoid the terminal and audio playback caused by the application being unable to respond to the data transmission request of the audio playback device during version update. Data transfer between devices is interrupted. That is, in the embodiment of the present invention, the data transmission between the terminal and the audio playback device can be kept uninterrupted while the version of the application is updated.

In addition, in this embodiment of the present invention, after the application is updated, the application can take over the data transmission connection between the terminal and the audio playback device again. Therefore, the embodiments of the present invention can improve the flexibility of data transmission between the terminal and the audio playback device.

Please refer to FIGS. 3A to 3C . FIGS. 3A to 3C are schematic diagrams of scenarios of a data transmission control method provided by an embodiment of the present invention.

For example, the mobile terminal establishes a data transmission connection with the audio playback device through a preset application, and transmits the audio data stored locally in the mobile terminal to the audio playback device for playback. As shown in FIG. 3A , the mobile terminal needs to transmit audio A to audio E in the local audio list to the audio playback device for playback.

In the process of data transmission between the mobile terminal and the audio playback device, the mobile terminal detects that the application has a new version, and asks the user whether to update the version of the application. At this time, the interface of the mobile terminal can be as shown in FIG. 3B .

For example, as shown in FIG. 3C , the user clicks the button "Yes" and chooses to update the version of the application. At this moment, the mobile terminal receives an instruction for instructing to update the version of the application. In this case, the mobile terminal may create the first process first.

Then, the mobile terminal can determine the second process corresponding to the application, and obtain the running time data of the second process. The second process is the process corresponding to the application in the terminal for data transmission with the audio playback device at this time.

After acquiring the running time data of the second process, the terminal may transmit the running time data of the second process to the first process through inter-process communication. Afterwards, the mobile terminal may establish a data transmission connection with the audio playback device based on the first process, and respond to the data transmission request of the audio playback device. That is to say, at this time, the first process takes over the data transmission connection between the mobile terminal and the audio playback device originally managed by the second process.

After detecting that the version update of the application is completed, the mobile terminal can restart the application and detect whether the first process is terminated.

For example, at this time, it is detected that the first process is not terminated, that is, the mobile terminal still maintains a data transmission connection with the audio playback device through the first process. In this case, the mobile terminal may create a third process corresponding to the application after the version update is completed. Then, the mobile terminal may acquire the running time data of the first process at this time, and transmit the running time data of the first process to the third process through inter-process communication.

After the third process acquires the runtime data of the first process, the mobile terminal may establish a data transmission connection with the audio playback device based on the third process. That is to say, at this time, the third process takes over the data transmission connection between the mobile terminal and the audio playback device that was previously managed by the first process.

Thereafter, the mobile terminal may terminate the above-mentioned first process.

For example, after the obtaining module 302 obtains the running time data of the second process, the transmitting module 303 may transmit the running time data of the second process to the first process through inter-process communication.

It should be noted that inter-process communication is a technology that can communicate data between different processes. For example, if the terminal is installed with an Android operating system, the terminal may use the AIDL (Android Interface Definition Language, Android Interface Definition Language) process communication technology to implement communication between different processes. For another example, in the Android operating system, a Messenger-based technology may also be used to implement cross-process communication, and so on. It should be understood that the examples herein do not constitute a limitation to the present invention.

The response module 304 is configured to establish a data transmission connection between the terminal and the audio playback device based on the first process that obtains the running time data of the second process, so as to respond to the data transmission request of the audio playback device.

For example, the first process transmits the local audio data saved in the terminal to the audio playback device for playback.

It can be understood that the runtime data of the second process includes the relevant data of the data transmission connection established between the terminal and the audio playback device (through the application), so the runtime data of the second process is transmitted to the first process. After the process, the terminal can establish a data transmission connection with the audio playback device based on the first process.
