"从主线程中调用此函数可能会导致从GoogleAuthUtil获取accessToken时出现死锁和/或ANR"(Google Plus中的Google Plus集成)

Question

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

accessToken = GoogleAuthUtil.getToken(this,mPlusClient.getAccountName(),"oauth2:"+ SCOPES);

但在这一行我得到的错误如下:

E/GoogleAuthUtil(4696):调用此从你的主线程可以导致死锁和/或ANR的E/GoogleAuthUtil(4696):java.lang.IllegalStateException:调用该从你的主线程可以导致死锁E/GoogleAuthUtil(4696) :在com.google.android.gms.auth.GoogleAuthUtil.b(未知来源)E/GoogleAuthUtil(4696):在com.google.android.gms.auth.GoogleAuthUtil.getToken(未知来源)E/GoogleAuthUtil(4696) :at com.google.android.gms.auth.GoogleAuthUtil.getToken(Unknown Source)

任何这个问题的解决方案？任何帮助将不胜感激.

尝试使用AsyncTask,如下所示:

        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是一个以空格分隔的OAuth 2.0范围字符串列表.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.此示例中请求的范围记录在此处:

• https://developers.google.com/+/api/oauth
• https://developers.google.com/drive/android/files
