Для записей Access Salesforce в Android Native App без учетных данных для входа сначала необходимо получить токен доступа у salesforce.
Чтобы получить токен доступа, перейдите по этой ссылке.https://developer.salesforce.com/docs/atlas.en-us.api_rest.meta/api_rest/quickstart_oauth.htm
После получения токена необходимо выполнить вызовы REST для получения записей Salesforce.
