Where are the AccountManager Accounts stored? Is it on the device? If yes in which folder is it stored?
It is stored here:
Environment.getSystemSecureDirectory().getPath() + File.separator + DATABASE_NAME;
Where getSystemSecureDirectory:
Gets the system directory available for secure storage. If Encrypted File system is enabled, it returns an encrypted directory (/data/secure/system). Otherwise, it returns the unencrypted /data/system directory.
and DATABASE_NAME = "accounts.db";
