Attributes

Remarks

Prepare for a get-credential operation. Returns a PrepareGetCredentialResponse that can launch the credential retrieval UI flow to request a user credential for your app.

This API doesn't invoke any UI. It only performs the preparation work so that you can later launch the remaining get-credential operation (involves UIs) through the #getCredential(PrepareGetCredentialResponse.PendingGetCredentialHandle, Context, CancellationSignal, Executor, OutcomeReceiver) API which incurs less latency compared to the #getCredential(GetCredentialRequest, Context, CancellationSignal, Executor, OutcomeReceiver) API that executes the whole operation in one call.
