@parcool This is best asked on the geonet forum, but since you are here I will offer comments. There is no API for caching data in the ArcGIS Android SDK so you as a developer have to manage cache of objects yourself. We do have an example of caching retrieved Basemaps in the MaterialBasemaps MainActivity which shows one way to accomplish this using the PersistBasemapItem class.
