来自GoogleAuthUtil的"Calling this from your main thread can lead to deadlock and/or ANRs while getting



在我的android应用程序中,我正试图从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):从主线程调用它可能会导致死锁和/或ANRE/GoogleAuthUtil(4696):java.lang.IllegalStateException:从主线程调用它可能导致死锁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):在com.google.android.gms.auth.GoogleAuthUtil.getToken(未知来源)

这个问题有什么解决办法吗?任何帮助都将不胜感激。

用这样的AsyncTask试试:

        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作用域字符串的以空格分隔的列表。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";

这些代表您的应用程序向用户请求的权限。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

为您的互联网代码使用单独的线程。错误表明更多耗时的进程正在应用程序中运行,这里是互联网。因此,请使用单独的线程或异步任务。

查看此链接NetworkOnMainThreadException

希望它能帮助你。

E/GoogleAuthUtil(4696):java.lang.IollegalStateException:调用从您的主线程可以导致死锁

听起来你需要在一个单独的线程上这样做,你尝试过吗?

在这里你可以找到关于Android线程的信息。

            Thread CrearEventoHilo = new Thread(){
                public void run(){
                    //do something that retrun "Calling this from your main thread can lead to deadlock"
                }
            };
            CrearEventoHilo.start();

CrearEventoHilo.interrupt()

public class Foo {
    MyThread mTh;
    void cantBeBothered() {
        mTh = new MyThread( /*...*/ );
        mTh.run();
        mTh.start();
    }
    void imFinishedNowWaitingForThread() {
        mTh.join();
    }
    void imOutKillingOffPendingThread()  {
        mTh.interrupt();
    }
//  .....
    private class MyThread extends Thread {
//      ...;
        MyThread( /*...*/) {
//          this... = ...;
        }
        public void run() {
            doSomething( /*this...*/ );
        }
    }
}
