How to retrieve all the accounts in Android Device?

With the help of Account Manager we can retrieve the list of all account in android device..


public String getUsername() {
AccountManager manager = AccountManager.get(this);
Account[] accounts = manager.getAccountsByType("com.google");
List<String> possibleEmails = new LinkedList<String>();


for (Account account : accounts) {
/*We can fetch account name using:
account.name;
and the encrypted password using:
manager.getPassword(account);*/
possibleEmails.add(account.name);

}


if (!possibleEmails.isEmpty() && possibleEmails.get(0) != null) {
String email = possibleEmails.get(0);
String[] parts = email.split("@");
if (parts.length > 0 && parts[0] != null)
return parts[0];
else
return null;
} else
return null;
}
