step S708, caching, assembling a page turning operation message and sending the page turning operation message to the control, and entering step S716;
step S710, no cache exists, and page information is requested from the control;
step S712, the control carries out base64 coding on the file information and returns the file information to the android conversion library;
step S714, the android conversion library displays and caches the file information on a conference chairman page, and then the step S708 is executed;

step S718, the core network sends page information to the conference members;
step S720, the control returns page information to the android;
in step S722, the android interface program displays the file information on the conference member page.
Two conversion schemes of the control to the shared document are described in detail below:
example one
The implementation scheme of sharing the DOC document in the Android client conference comprises the following steps:
step one, after entering a document sharing data conference, a conference chairman uses an android app interface developed by java to enable a user to select a DOC file to be shared. And transmitting information such as a document path selected by a user to a control and caching the information, converting the first page of the DOC file into picture information by the control through a virtual printing technology, and returning the picture information to the Android after the picture information is coded by base 64.
Preferably: since a document may be large, its size grows in multiples after being converted into picture information. Therefore, the file is only converted by taking the page as a unit, and the condition that the message transmission is abnormal among different modules due to overlarge converted file information is prevented.
And step two, after receiving the picture information, the Android displays the picture information on an Android interface developed by java in a whiteboard background picture mode. And the file information is assembled into custom information in an XML format and is sent to the control, and the control sends the custom information to the IMS server.
And step three, after receiving the document sharing message, the IMS server divides the message to each conference member, extracts the picture information of the shared document from the member page, and displays the picture information on the Android interface developed by java in the form of a whiteboard background picture. Preferably, the conference member page loading speeds are not substantially the same for system reasons. Therefore, when receiving the document sharing notification of the IMS server, the conference members should cache the page information; after the interface is normally loaded, the page information is displayed, and the situation that the page is required to be displayed when the page is not loaded is prevented.
And step four, after the steps, the conference chairman and the conference members can both display the information of the first page of the file. At this time, the conference chairman and the conference members can operate on the Android interface through the whiteboard function, such as drawing, screen capturing, text adding and the like.
And step five, after the first page is displayed, the conference chairman can perform page turning operation. After page turning operation is carried out, Android can firstly judge whether picture information of a target page exists in a cache or not, if yes, the target page information is assembled into a self-defined message and sent to a control, and the control forwards the self-defined message to an IMS server; and if not, the file path and the target page information to be displayed are sent to the control, the control returns the picture information of the target page, the picture information is displayed on the Android interface and sent to the IMS server, and the server informs the member of displaying a new page, so that the page turning effect is realized.
And step six, the chairman of the conference can store the shared page information for the next use. After the chairman performs the document saving operation, all cached page information is sent to the control by taking a page as a unit, and for the undisplayed pages, the page information is also converted into picture information and is saved in the same file, wherein the file is in an XWB file format defined by the system.
Example two
The implementation scheme of sharing PPT or PPS documents in the Android client conference comprises the following steps:
step one, after entering a document sharing data conference, a conference chairman uses an Android interface developed by java to enable a user to select PPT or PPS files needing to be shared. And transferring information such as a document path selected by a user to the control, caching the information such as the file name and the path, renaming the document to a PPS (polyphenylene sulfide) format by the control, and uploading the document to the IMS server.
And step two, after receiving the document, the IMS server redistributes the document to each conference member. After the conference member downloads the PPT document to the default path, the conference member returns a file downloading success message to the IMS server. The IMS server sends a download completion message to the conference chairman after judging that all conference members successfully download the documents, and at the moment, an Android page sharing button of the conference chairman can be used, namely PPT file sharing operation can be carried out; otherwise, the Android page sharing button of the conference chairman cannot be used, and PPT file sharing operation cannot be carried out.
And step three, clicking a sharing button by the conference chairman to share the PPT file. And the Android sends the cached file information to the control, the control opens the specified PPT file and monitors the opened PPT file, and sends the message to the IMS server, and the server informs all members to share the PPT file.
And step four, after the PPT document is opened, if the conference chairman end monitors that the PPT document is operated, for example, page turning is carried out, sending a page turning request to the IMS server, and informing each conference member by the IMS server to carry out page turning operation.
And step five, prompting whether the document is saved or not after the PPT document sharing is quitted. If yes, sending a file saving request to the IMS server, and saving the file.
The preferred embodiment realizes sharing and synchronous operation of common documents in the conference, and has important significance for improving network cooperation and conference communication effect and efficiency.
