+ * <p>This class is used to provide some input suggestions to the Autofill framework.
+ *
+ * <P>When the user is requested to input something, Autofill will try to query input suggestions
+ * for the user choosing. If the application want to provide some internal input suggestions,
+ * implements this callback and register via
+ * {@link AutofillManager#setAutofillRequestCallback(java.util.concurrent.Executor,
+ * AutofillRequestCallback)}. Autofill will callback the
+ * {@link #onFillRequest(InlineSuggestionsRequest, CancellationSignal, FillCallback)} to request
+ * input suggestions.
+ *
+ * <P>To make sure the callback to take effect, must register before the autofill session starts.
+ * If the autofill session is started, calls {@link AutofillManager#cancel()} to finish current
+ * session, and then the callback will be used at the next restarted session.
+ *
+ * <P>To create a {@link android.service.autofill.FillResponse}, application should fetch
+ * {@link AutofillId}s from its view structure. Below is an example:
+ * <pre class="prettyprint">
+ * AutofillId usernameId = findViewById(R.id.username).getAutofillId();
+ * AutofillId passwordId = findViewById(R.id.password).getAutofillId();
+ * </pre>
+ * To learn more about creating a {@link android.service.autofill.FillResponse}, read
+ * <a href="/guide/topics/text/autofill-services#fill">Fill out client views</a>.
+ *
+ * <P>To fallback to the default {@link android.service.autofill.AutofillService}, just respond
+ * a null of the {@link android.service.autofill.FillResponse}. And then Autofill will do a fill
+ * request with the default {@link android.service.autofill.AutofillService}. Or clear the callback
+ * from {@link AutofillManager} via {@link AutofillManager#clearAutofillRequestCallback()}. If the
+ * client would like to keep no suggestions for the field, respond with an empty
+ * {@link android.service.autofill.FillResponse} which has no dataset.
+ *
+ * <P>IMPORTANT: This should not be used for displaying anything other than input suggestions, or
+ * the keyboard may choose to block your app from the inline strip.
