Question

I want to retrieve token via Account Manager classes. Here is sample code that works for twitter but not for facebook plz help me.

public class AccountManagerActivity extends Activity {

    AccountManager mAccountManager;
    AccountManagerFuture<Bundle> c;
    String token;


    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        mAccountManager = AccountManager.get(this);
        Account[] acc = mAccountManager.getAccounts();
        for (int i = 1; i < acc.length; i++) {
            System.out.println("Account name==" + acc[i].name);
            System.out.println("Account Type==" + acc[i].type);
        }
        AuthenticatorDescription[] ad = mAccountManager.getAuthenticatorTypes();
        for (int i = 1; i < ad.length; i++) {
            System.out.println("AuthenticatorDescription==" + ad[i].type);
        }


        tokenForTwitter();
        tokenForFacebook();
    }

    private void tokenForFacebook() {
        Account[] accts = mAccountManager
                .getAccountsByType("com.facebook.auth.login");
        int i = 0;
        if (accts.length > 0) {
            System.out.println("here");
            Account acct = accts[0];
            c = mAccountManager.getAuthToken(acct,
                    "com.facebook.auth.token" , null,

Answer 1

Call AccountManager.getAccountsByType(null) to retrieve all accounts, and check the returned account data includes the information you need. It may simply not be exposed.

Try calling AccountManager.blockingGetAuthToken instead. Also, make sure your manifest has the USE_CREDENTIALS permission set correctly.

You can see this discussion How to retrieve an Facebook-AuthToken from the accounts saved on Android

But I would also suggest Facebook SDK with offline access permission(This permission makes the access token returned by the OAuth endpoint long-lived, otherwise auth token is valid only for 1 hour.)
