ACCOUNT_TYPE
The android.accounts account type under which Android Solid Services registers every signed-in Solid profile (account name = WebID). Third-party apps can offer the system account chooser over it — AccountManager.newChooseAccountIntent filtered to this type, or the SDK's ChooseSolidAccount contract. Picking an account there makes it visible to the picking app, mediated by the OS; it does not by itself grant pod access, which is what the authorize flow is for. Accounts of this type carry no tokens: DPoP tokens are bound to keys that never leave Android Solid Services.
