在Android中使用帐户管理器进行帐户身份验证

Question

我正在尝试对帐户进行身份验证，但仅在响应中获取帐户名，帐户类型。我如何获取所有帐户详细信息，例如访问令牌，刷新令牌，令牌到期时间，帐户名，帐户类型。这样我就可以检查令牌是否已过期/有效。我的代码如下：

if(accountsFromFirstApp.length >= 1) {
        System.out.println("Account found.");
        for(Account acct: accountsFromFirstApp){
            System.out.println("am.getAccounts()"+ am.getAccounts());

            // String authToken = am.peekAuthToken(accountsFromFirstApp[0], getString(R.string.auth_type));

            System.out.println("acct.name "+ acct.name);
            AccountManagerFuture<Bundle> ah = am.getAuthToken(accountsFromFirstApp[0], "ah", false, null, null);

            System.out.println("userdata "+ am.getAuthToken(accountsFromFirstApp[0], "ah", false, null, null));                // Get the auth token
            //Bundle options = null;
            Activity activity = null;
            AccountManagerCallback<Bundle> callback = null;
            Handler handler = null;
            AccountManagerFuture<Bundle> future = am.getAuthToken(
                    acct, AUTH_TYPE, options, activity, callback, handler);

            try {
                String token = future.getResult().getString(AccountManager.KEY_AUTHTOKEN);
                System.out.println("token:"+ token);
            } catch(Exception e) {
                e.printStackTrace();
            }
            // System.out.println("acct.user.data "+ am.getUserData(acct, "key.for.secure.user.data"));
        }
    }else{
        System.out.println("No account found!");
    }
