在我的Android应用程序中，我试图从GoogleAuthUtil获取AccessToken，如下所示:



但是在这一行，我得到如下错误:



这个问题有什么解决办法吗？任何帮助将不胜感激。

像这样使用AsyncTask尝试一下:

        AsyncTask<Void, Void, String> task = new AsyncTask<Void, Void, String>() {
            @Override
            protected String doInBackground(Void... params) {
                String token = null;

                try {
                    token = GoogleAuthUtil.getToken(
                            MainActivity.this,
                            mGoogleApiClient.getAccountName(),
                            "oauth2:" + SCOPES);
                } catch (IOException transientEx) {
                    // Network or server error, try later
                    Log.e(TAG, transientEx.toString());
                } catch (UserRecoverableAuthException e) {
                    // Recover (with e.getIntent())
                    Log.e(TAG, e.toString());
                    Intent recover = e.getIntent();
                    startActivityForResult(recover, REQUEST_CODE_TOKEN_AUTH);
                } catch (GoogleAuthException authEx) {
                    // The call is not ever expected to succeed
                    // assuming you have already verified that
                    // Google Play services is installed.
                    Log.e(TAG, authEx.toString());
                }

                return token;
            }

            @Override
            protected void onPostExecute(String token) {
                Log.i(TAG, "Access token retrieved:" + token);
            }

        };
        task.execute();

SCOPES是OAuth 2.0范围字符串的用空格分隔的列表。例如，SCOPES可以定义为:

public static final String SCOPES = "https://www.googleapis.com/auth/plus.login "
    + "https://www.googleapis.com/auth/drive.file";

这些代表您的应用向用户请求的权限。此示例中要求的范围记录在这里:

https://developers.google.com/+/api/oauth
