public final class PreviewRegistry extends DigitalCredentialRegistry

java.lang.Object
↳	androidx.credentials.registry.provider.RegisterCredentialsRequest
	↳	androidx.credentials.registry.provider.digitalcredentials.DigitalCredentialRegistry
		↳	androidx.credentials.registry.digitalcredentials.preview.PreviewRegistry

The preview protocol is the example digital credential protocol widely used by test sites. You can view or test with it at digital-credentials.dev.

Summary

Public constructors
`PreviewRegistry( @NonNull List<@NonNull DigitalCredentialEntry> credentialEntries, @NonNull String id )`

`final @NonNull byte[]`	`getCredentials()` the credentials to register
`final @NonNull String`	`getId()` the unique id that identifies this registry, such that it won't be overwritten by other different registries of the same `type`
`final @NonNull byte[]`	`getMatcher()` the matcher wasm binary in bytes; the matcher will be interpreted and run in a safe and privacy-preserving sandbox upon an incoming request and it should output the qualified credentials given the `credentials` and the request; an invalid matcher (e.g. one that fails wasm interpretation or causes exceptions) will mean that your credentials will never be surfaced to the user
`final @NonNull String`	`getType()` the type of the credentials being registered

public PreviewRegistry(
    @NonNull List<@NonNull DigitalCredentialEntry> credentialEntries,
    @NonNull String id
)

Parameters
`@NonNull List<@NonNull DigitalCredentialEntry> credentialEntries`	the list of entries to register
`@NonNull String id`	the provider unique id that identifies this registry, such that it won't be overwritten by other different registries of the same type; default to a preview specific ID which should be used unless you need to maintain multiple preview protocol based registries at the same time
