Question

我正在我的应用上实施谷歌智能锁，目前，我们只在应用程序端实现，一旦他允许保存凭据，在重新安装时自动登录用户。但是当我从password.google.com中删除密码时，或者当我在Google帐户没有为该应用程序存储凭据的设备上运行应用程序时，该库会显示一个对话框，建议其他网站和应用程序的电子邮件。我需要禁用此行为，我只想建议凭据和电子邮件，如果它们属于我的应用程序。

我使用以下代码请求凭据：

    private void requestCredentials() {
            CredentialRequest request = new CredentialRequest.Builder()
                   .setPasswordLoginSupported(true)
                   .setIdTokenRequested(true)
                   .build();
            mProgressSmartLock.show();
    credentialsClient.request(request).addOnCompleteListener(credentialsApiRequestCompleteListener());
    }

和听众：

    public OnCompleteListener<CredentialRequestResponse> credentialsApiRequestCompleteListener(){
            return new OnCompleteListener<CredentialRequestResponse>() {
                @Override
                public void onComplete(@NonNull Task<CredentialRequestResponse> task) {
                // Successfully read the credential without any user interaction, this
                // means there was only a single credential and the user has auto
                // sign-in enabled.
                mProgressSmartLock.dismiss();
                if (task.isSuccessful()) {
                    processRetrievedCredential(task.getResult().getCredential());
                    return;
                }

                    // This is most likely the case where the user has multiple saved
                // credentials and needs to pick one. This requires showing UI to
                // resolve the read request.
                Exception e = task.getException();
                if (e instanceof ResolvableApiException) {
                    ResolvableApiException rae = (ResolvableApiException) e;
                    resolveResult(rae, RC_READ);
                    return;
                }

                // This means only a hint is available
                if (e instanceof ApiException) {
                    Crashlytics.logException(e);
                }
            }
        };
    }

保存凭据：

private void saveCredentials(String email, String password) {
        final Credential credential = new Credential.Builder(email)
                .setPassword(password)
                .build();

        mProgress.show();

        credentialsClient.save(credential).addOnCompleteListener(credentialsApiSaveCompleteListener());
}

监听器：

public OnCompleteListener<Void> credentialsApiSaveCompleteListener(){
    return new OnCompleteListener<Void>() {
        @Override
        public void onComplete(@NonNull Task<Void> task) {
            if (task.isSuccessful()) {
                mProgress.dismiss();
                return;
            }

            Exception e = task.getException();
            if (e instanceof ResolvableApiException) {
                // The first time a credential is saved, the user is shown UI
                // to confirm the action. This requires resolution.
                ResolvableApiException rae = (ResolvableApiException) e;
                resolveResult(rae, RC_SAVE);
            } else {
                // Save failure cannot be resolved.
                mProgress.dismiss();
            }
        }
    };
}

要避免出现此对话框（即使没有保存密码，该对话框也会列出所有电子邮件地址，以帮助填写表单），请不要解析任务的getStatusCode()是否返回SIGN_IN_REQUIRED。

如果凭据不是来自应用程序，或者应用程序未保存任何凭据，则statusCode将是SIGN_IN_REQUIRED。但是，如果您之前保存过任何凭据，则会从INT收到另一个statusCode值。您可以在Resolveable Exception中进行判断。

智能锁显示的帐户不是来自我的应用
