createTextClassificationSession

fun createTextClassificationSession(classificationContext: TextClassificationContext): TextClassifier

Call this method to start a text classification session with the given context. A session is created with a context helping the classifier better understand what the user needs and consists of queries and feedback events. The queries are directly related to providing useful functionality to the user and the events are a feedback loop back to the classifier helping it learn and better serve future queries.

All interactions with the returned classifier are considered part of a single session and are logically grouped. For example, when a text widget is focused all user interactions around text editing (selection, editing, etc) can be grouped together to allow the classifier get better.

getTextClassifier

fun getTextClassifier(): TextClassifier

Returns the text classifier that was set via setTextClassifier(android.view.textclassifier.TextClassifier). If this is null, this method returns a default text classifier (i.e. either the system text classifier if one exists, or a local text classifier running in this process.)

Note that requests to the TextClassifier may be handled in an OEM-provided process rather than in the calling app's process.

setTextClassificationSessionFactory

fun setTextClassificationSessionFactory(factory: TextClassificationSessionFactory?): Unit

Sets a TextClassificationSessionFactory to be used to create session-aware TextClassifiers.

setTextClassifier

fun setTextClassifier(textClassifier: TextClassifier?): Unit

Sets the text classifier. Set to null to use the system default text classifier. Set to TextClassifier#NO_OP to disable text classifier features.
