ChatMessage

public class ChatMessage : LinphoneObject

An chat message is the object that is sent or received through a ChatRoom. To create a ChatMessage, use ChatRoom.createEmptyMessage(), then either add text using addUtf8TextContent() or a Content with file informations using addFileContent(). A valid Content for file transfer must contain a type and subtype, the name of the file and it’s size. Finally call send() to send it. To send files through a ChatMessage, you need to have configured a file transfer server URL with Core.setFileTransferServer(). On the receiving side, either use downloadContent() to download received files or enable auto-download in the Core using Core.setMaxSizeForAutoDownloadIncomingFiles(), -1 disabling the feature and 0 always downloading files no matter it’s size. Keep in mind a ChatMessage created by a Basic ChatRoom can only contain one Content, either text or file.
