        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++) {

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.)

It's always returning 0 results now on Android M – Dpedrinha Apr 04 '16 at 02:34 — Dpedrinha, Apr 04 '16 at 02:34

You can also create intent and obtain token from facebook application

Intent intent = new Intent();
intent.setClassName("com.facebook.katana", "com.facebook.katana.ProxyAuth");
intent.putExtra("client_id", apiKey);
intent.putExtra("scope", scope);

try {
    activity.startActivityForResult(intent, requestCode);
} catch (ActivityNotFoundException e) {
    return false;
}

Then onActivityResult(int requestCode, int resultCode, Intent data) of you activity you can get the token using

data.getStringExtra("access_token");

Just for information, the facebook application part of getAuthToken is not implemented. When you decompile it, you see that it just returns null.

You should use the Facebook SDK.
