SyncAdapter Without an Account

Question

I\'m trying to create a SyncAdapter for my Android app to show YouTube videos from one specific channel. The videos are public domain so I don\'t want the user to login, create

Answer 1

In short the answer is: ContentProvider, AccountManager and SyncAdapter go together. You must have these three pieces, even if they are "dumb".

Answer 2

As stated above, "ContentProvider, AccountManager and SyncAdapter go together". For your application you can call the following activity the first time your app is loaded to authenticate and start synching automatically:

public class LoginActivity extends AccountAuthenticatorActivity {

private final static String DUMMY_ACCOUNT_NAME = "some_name";
private final static String DUMMY_ACCOUNT_PASS = "some_pass";
private final static String AUTHORITY = "com.android.contacts"; // for example

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Account account = new Account(DUMMY_ACCOUNT_NAME, Constants.ACCOUNT_TYPE);
    AccountManager am = AccountManager.get(this);
    if (am.addAccountExplicitly(account, DUMMY_ACCOUNT_PASS, null)) {
        Bundle result = new Bundle();
        result.putString(AccountManager.KEY_ACCOUNT_NAME, account.name);
        result.putString(AccountManager.KEY_ACCOUNT_TYPE, account.type);
        setAccountAuthenticatorResult(result);
        ContentResolver.setSyncAutomatically(account, AUTHORITY, true);
    }

    finish();
 }
}

This works in Android API 5+.
