Public constructors

Message

Added in API level 28

public Message (CharSequence text, 
                long timestamp, 
                Person sender)

Constructor

Parameters

Parameters
`text`	`CharSequence`: A `CharSequence` to be displayed as the message content This value cannot be `null`.
`timestamp`	`long`: Time at which the message arrived
`sender`	`Person`: The `Person` who sent the message. Should be `null` for messages by the current user, in which case the platform will insert the user set in `MessagingStyle(Person)`. The person provided should contain an Icon, set with `Person.Builder.setIcon(Icon)` and also have a name provided with `Person.Builder.setName(CharSequence)`. If multiple users have the same name, consider providing a key with `Person.Builder.setKey(String)` in order to differentiate between the different users.

text

CharSequence: A CharSequence to be displayed as the message content This value cannot be null.

timestamp

long: Time at which the message arrived

sender

Person: The Person who sent the message. Should be null for messages by the current user, in which case the platform will insert the user set in MessagingStyle(Person).

The person provided should contain an Icon, set with Person.Builder.setIcon(Icon) and also have a name provided with Person.Builder.setName(CharSequence).

setData

Added in API level 24

public Notification.MessagingStyle.Message setData (String dataMimeType, 
                Uri dataUri)

Sets a binary blob of data and an associated MIME type for a message. In the case where the platform or the UI state doesn't support the MIME type, the original text provided in the constructor will be used. When this data can be presented to the user, the original text will only be used as accessibility text.

Parameters

Parameters
`dataMimeType`	`String`: The MIME type of the content. See `ImageDecoder.isMimeTypeSupported(String)` for a list of supported image MIME types.
`dataUri`	`Uri`: The uri containing the content whose type is given by the MIME type. Notification Listeners including the System UI need permission to access the data the Uri points to. The recommended ways to do this are: Store the data in your own ContentProvider, making sure that other apps have the correct permission to access your provider. The preferred mechanism for providing access is to use per-URI permissions which are temporary and only grant access to the receiving application. An easy way to create a ContentProvider like this is to use the FileProvider helper class. Use the system MediaStore. The MediaStore is primarily aimed at video, audio and image MIME types, however beginning with Android 3.0 (API level 11) it can also store non-media types (see MediaStore.Files for more info). Files can be inserted into the MediaStore using scanFile() after which a content:// style Uri suitable for sharing is passed to the provided onScanCompleted() callback. Note that once added to the system MediaStore the content is accessible to any app on the device.
