What Is Hidden Cache on Android?Īpps like YouTube, Spotify, or Reddit constantly download a lot of data to serve the content you enjoy so much. In this article, we explain what hidden cache is on Android, and we also provide step-by-step instructions that you can follow to empty it. Why not? Because the problem is actually caused by something called hidden cache. For example, clicking on an origin which is a child of the Cookies storage type will show all the cookies belonging to that domain.Android devices are plagued by one annoying problem: available storage space seems to disappear over time, and it’s impossible to reclaim it all just by deleting files and apps. The tree is live, so if a new origin gets added (by adding an iframe, for example), it will be added to each storage type automatically.Ĭlicking on a tree item will display detailed information about that item in the Table Widget on the right. You can click on each item in the tree to expand or collapse its children. With the Cookies, Local Storage, and Session Storage types, there’s only one level in the hierarchy, so stored items are listed directly under each origin: IndexedDB objects are organized by origin, then by database name, then by object store name:

Under “Cache Storage”, objects are organized by origin and then by the name of the cache: For example, “ ” and “ ” are two different origins so local storage items cannot be shared between them. For Indexed DB or local storage an origin is a combination of protocol + hostname.

For cookies, the protocol does not differentiate the origin.

Under each type, objects are organized by origin. The storage tree lists all the storage types that the Storage Inspector can inspect:
