abstract member AddMessage : Android.App.Notification.MessagingStyle.Message -> Android.App.Notification.MessagingStyle
override this.AddMessage : Android.App.Notification.MessagingStyle.Message -> Android.App.Notification.MessagingStyle

Parameters

message: Notification.MessagingStyle.Message

Notification.MessagingStyle.Message: The Message to be displayed

Returns

Notification.MessagingStyle

this object for method chaining

Attributes: RegisterAttribute

Remarks

Adds a Message for display in this notification. The messages should be added in chronologic order, i.e. the oldest first, the newest last. Multiple Messages in a row with the same timestamp and sender may be grouped as a single message. This means an app should represent a message that has both an image and text as two Message objects, one with the image (and fallback text), and the other with the message text. For consistency, a text message (if any) should be provided after Uri content.
