Public methods
onFailure
fun onFailure(message: CharSequence?): Unit
Notifies the Android System that a fill request ( AutofillService#onFillRequest(FillRequest, android.os.CancellationSignal,
) could not be fulfilled by the service (for example, because the user data was not available yet), so the request could be retried later.
Note: this method should not be used when the service didn't have the heursitics to fulfill the request; in this case, the service should call onSuccess(null)
instead.
Note: prior to android.os.Build.VERSION_CODES#Q
, this method was not working as intended and the service should always call onSuccess(null)
instead.
Note: for apps targeting android.os.Build.VERSION_CODES#Q
or higher, this method just logs the message on logcat
; for apps targetting older SDKs, it also displays the message to user using a android.widget.Toast
. Generally speaking, you should not display an error to the user if the request failed, unless the request had the FillRequest#FLAG_MANUAL_REQUEST
flag.
Parameters | |
---|---|
message |
CharSequence?: error message. Note: this message should not contain PII (Personally Identifiable Information, such as username or email address). This value may be null . |
Exceptions | |
---|---|
java.lang.IllegalStateException |
if this method or onSuccess(android.service.autofill.FillResponse) was already called. |
onSuccess
fun onSuccess(response: FillResponse?): Unit
Notifies the Android System that a fill request (AutofillService#onFillRequest(FillRequest, android.os.CancellationSignal,
) was successfully fulfilled by the service.
This method should always be called, even if the service doesn't have the heuristics to fulfill the request (in which case it should be called with null
).
See the main AutofillService
documentation for more details and examples.
