[0011] Further, after the user triggers the button directly through the front-end page, the front-end page transmits the message to the Android message receiving module by calling the agreed Http interface.

[0012] Further, the front-end page transmits the wake-up message or the sleep message to the Android message receiving module by calling the agreed Http interface.

[0013] Further, the method for the Android message receiving module to analyze the message is: if the message is a wake-up message, the switch of the voice processing module is opened, if the message is a sleep message, the switch of the voice processing module is closed, and the ongoing voice processing logic is ended.

[0014] Further, the message sending module publishes the message to the specified Topic through MQTT after receiving the text.

[0015] Further, the message entity published by the message sending module to the specified Topic carries the received text content after receiving the text.

[0016] An Android-based message transceiving system, comprising:

[0017] A message receiving module, which sets up a micro server by integrating NanoHTTPD, and an external device transmits data to the message receiving module by calling the defined Http interface;

[0018] A message sending module, which publishes messages to a specified Topic through the MQTT protocol, and an external device receives the published messages by subscribing to the Topic;

[0019] A voice processing module, which comprises audio acquisition, voice device, and audio output functions realized based on the Android system, receives messages from the message receiving module, transmits messages to the message sending module, and interacts with the server-side natural language processing module;

[0020] A natural language processing module, which serves as a server-side module, comprises semantic understanding, answer generation, and speech synthesis functions, and interacts with the natural language processing module;

[0021] A front-end display module, which serves as a front-end display page, interacts with the Android-side message receiving module and the message sending module, and is touched by the user, sends messages to the Android side after responding to the user's intention, and receives the processed messages from the Android side, and displays the content to the user.

[0022] A non-volatile computer storage medium stores computer executable instructions arranged to:

[0023] The front-end page transmits messages to the Android message receiving module by calling the agreed Http interface.

[0024] After the Android message receiving module receives the message transmitted by the front-end page, the message is parsed to determine whether to start the voice processing module.

[0025] After the voice processing module is opened, audio streams are collected in real time, voice recognition is performed on the audio streams, the recognized text is transmitted to the server natural language processing module, the server natural language processing module intelligently generates answers and audio streams and synchronously transmits them to the voice processing module, the voice processing module plays the synthesized audio and sends the text to the message sending module.

[0026] The message sending module publishes messages to a specified Topic after receiving the text.

[0027] The front-end display module receives the messages published by the message sending module by subscribing to the specified Topic, obtains the text content after parsing the message entity, and displays the text content on the page.

[0028] The Android can serve as a bridge for message transmission and has the functions of message receiving and message sending. The Android client is endowed with the function of the server, can deploy Http services, define Http interfaces, accept and process Http requests, and based on this function, components such as the front-end page that cannot directly communicate with the Android end can directly transmit messages by sending Http requests, thereby increasing the diversity and expandability of the functions of the Android application.
