The following details the two conversion schemes of the control for shared documents:

Embodiment 1

The Android client conference sharing DOC document implementation program includes the following steps:

Step 1: After entering the document sharing data conference, the conference chairperson uses the Android app interface developed by java to let the user select the DOC file that needs to be shared. The information such as the document path selected by the user is passed to the control and the information is cached, and the first page of the DOC file is converted into image information by the control through the virtual printing technology, and the base64 is encoded and returned to the Android.

Preferably: since a document may be large, its size is multiplied after being converted into picture information. Therefore, here is just a conversion of the file in units of pages, preventing the file information from being too large after the conversion, resulting in an abnormality in message delivery between different modules.

Step 2: After receiving the picture information, Android displays the picture information in the form of a whiteboard background image on the Android interface developed by Java. And the file information is assembled into a custom information in an XML format and sent to the control, and the control sends the custom message to the IMS server.

Step 3: After receiving the message shared by the document, the IMS server divides the message into the conference members, and the member page extracts the picture information of the shared document, and also displays the whiteboard background image in the Java interface of the Java development. Preferably, the conference member page loading speed is not the same for system reasons. Therefore, when receiving the document sharing notification of the IMS server, the conference member should first cache the page information; after the interface is normally loaded, the page information is displayed to prevent the page from being displayed when the page is not loaded yet.

Step 4: After the above steps, the conference chairperson and conference members can display the information on the first page of the document. At this point, the conference chairperson and conference members can use the whiteboard function to perform operations on the Android interface, such as drawing, screen capture, adding text, and so on.

In step five, after the first page is displayed, the conference chairperson can perform a page turning operation. After the page turning operation, Android will first determine whether there is image information of the target page in the cache, and if so, assemble the target page information into a custom message, send it to the control, and forward it to the IMS server by the control; if not, then Sending the file path and the target page information to be displayed to the control, the control returns the picture information of the target page, and then displays the information on the Android interface, and sends a message to the IMS server, and the server notifies the member to display the new page, and realizes page turning. effect.

In step 6, the conference chairperson can save the shared page information for the next use. After the document save operation, the chair will send all the cached page information to the control in units of pages. For the undisplayed pages, it will also be converted into image information and saved in the same file. The file is customized by the system. XWB file format.

Embodiment 2

The Android client conference sharing PPT or PPS document implementation scheme includes the following steps:

Step 1: After entering the document sharing data conference, the conference chairperson uses the Android interface developed by java to let the user select the PPT or PPS file that needs to be shared. The information such as the document path selected by the user is transmitted to the control, and the file name, path, and the like are cached, and the control renames the document to a PPS format document and uploads it to the IMS server.

Step 2: 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, it returns a file download success message to the IMS server. The IMS server determines that if all the conference members have successfully downloaded the document, send a download completion message to the conference chairperson. At this time, the conference chairman's Android page "share" button can be used, that is, the PPT file sharing operation can be performed. Otherwise; the “Share” button on the Android page of the conference chairperson cannot be used, and the PPT file sharing operation cannot be performed.

Step 3: The conference chairperson clicks the “Share” button to share the PPT file. Android sends the cached file information to the control, the specified PPT file is opened by the control and the opened PPT document is monitored, and the message is sent to the IMS server, and the server notifies each member to share the PPT document.

Step 4: After the PPT document is opened, if the PPT document is opened, if the PPT document is monitored, for example, the page turning is sent, the page turning request is sent to the IMS server, and the server notifies each meeting member to perform the page turning operation.

Step 5: After exiting the PPT document sharing, prompt whether to save the document. If yes, send a file save request to the IMS server and save the file.

The preferred embodiment realizes the sharing of common documents in a conference, and the synchronization of operations is important for improving network collaboration and improving conference communication effect and efficiency.
