“在获取 accesToken 时，从主线程调用它可能会导致死锁和/或 ANR"来自 GoogleAuthUtil(Android 中的 Google Plus 集成) [英] "Calling this from your main thread can lead to deadlock and/or ANRs while getting accesToken" from GoogleAuthUtil(Google Plus integration in Android)

问题描述

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

<块引用>

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

但是在这一行我得到如下错误:

<块引用><块引用>

E/GoogleAuthUtil(4696):从主线程调用它会导致死锁和/或 ANRE/GoogleAuthUtil(4696): java.lang.IllegalStateException: 从主线程调用它会导致死锁E/GoogleAuthUtil(4696):位于 com.google.android.gms.auth.GoogleAuthUtil.b(来源不明)E/GoogleAuthUtil(4696):在 com.google.android.gms.auth.GoogleAuthUtil.getToken(来源不明)E/GoogleAuthUtil(4696):位于 com.google.android.gms.auth.GoogleAuthUtil.getToken(来源不明)

这个问题有什么解决办法吗?任何帮助将不胜感激.

解决方案

试试这样的 AsyncTask:

 AsyncTasktask = new AsyncTask() {@覆盖受保护的字符串 doInBackground(Void... params) {字符串标记 = null;尝试 {令牌 = GoogleAuthUtil.getToken(MainActivity.this,mGoogleApiClient.getAccountName(),oauth2:"+ 范围)；} 捕捉(IOException瞬态Ex){//网络或服务器错误，稍后再试Log.e(TAG,transientEx.toString());} catch (UserRecoverableAuthException e) {//恢复(使用 e.getIntent())Log.e(TAG, e.toString());意图恢复 = e.getIntent();startActivityForResult(恢复，REQUEST_CODE_TOKEN_AUTH)；} 捕获(GoogleAuthException authEx){//调用永远不会成功//假设你已经验证过了//Google Play 服务已安装.Log.e(TAG, authEx.toString());}返回令牌；}@覆盖protected void onPostExecute(String token) {Log.i(TAG, "检索到的访问令牌:" + 令牌);}};任务.执行()；

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.本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

In my android application, I am trying to get AccessToken from GoogleAuthUtil as below :

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

But At this line I am gettting error as below :

E/GoogleAuthUtil(4696): Calling this from your main thread can lead to deadlock and/or ANRs E/GoogleAuthUtil(4696): java.lang.IllegalStateException: calling this from your main thread can lead to deadlock E/GoogleAuthUtil(4696): at com.google.android.gms.auth.GoogleAuthUtil.b(Unknown Source) E/GoogleAuthUtil(4696): at com.google.android.gms.auth.GoogleAuthUtil.getToken(Unknown Source) E/GoogleAuthUtil(4696): at com.google.android.gms.auth.GoogleAuthUtil.getToken(Unknown Source)

Any solution of this problem? Any help will be appreciated.

解决方案

Try it with an AsyncTask like this:

        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 is a space separated list of OAuth 2.0 scope strings. For example SCOPES could be defined as:

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

These represent the permissions that your app is requesting from the user. The scopes requested in this example are documented here:

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