我试图使用facebook登录来获取用户个人资料照片。

我使用此代码从示例Facebook代码登录到Facebook：

package com.facebook.samples.sessionlogin;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;
import com.facebook.LoggingBehavior;
import com.facebook.Session;
import com.facebook.SessionState;
import com.facebook.Settings;

public class LoginUsingActivityActivity extends Activity {
    private static final String URL_PREFIX_FRIENDS = "https://graph.facebook.com/me/friends?access_token=";

    private TextView textInstructionsOrLink;
    private Button buttonLoginLogout;
    private Session.StatusCallback statusCallback = new SessionStatusCallback();

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity);
        buttonLoginLogout = (Button)findViewById(R.id.buttonLoginLogout);
        textInstructionsOrLink = (TextView)findViewById(R.id.instructionsOrLink);

        Settings.addLoggingBehavior(LoggingBehavior.INCLUDE_ACCESS_TOKENS);

        Session session = Session.getActiveSession();
        if (session == null) {
            if (savedInstanceState != null) {
                session = Session.restoreSession(this, null, statusCallback, savedInstanceState);
            }
            if (session == null) {
                session = new Session(this);
            }
            Session.setActiveSession(session);
            if (session.getState().equals(SessionState.CREATED_TOKEN_LOADED)) {
                session.openForRead(new Session.OpenRequest(this).setCallback(statusCallback));
            }
        }

        updateView();
    }

    @Override
    public void onStart() {
        super.onStart();
        Session.getActiveSession().addCallback(statusCallback);
    }

    @Override
    public void onStop() {
        super.onStop();
        Session.getActiveSession().removeCallback(statusCallback);
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
    }

    @Override
    protected void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        Session session = Session.getActiveSession();
        Session.saveSession(session, outState);
    }

    private void updateView() {
        Session session = Session.getActiveSession();
        if (session.isOpened()) {
            textInstructionsOrLink.setText(URL_PREFIX_FRIENDS + session.getAccessToken());
            buttonLoginLogout.setText(R.string.logout);
            buttonLoginLogout.setOnClickListener(new OnClickListener() {
                public void onClick(View view) { onClickLogout(); }
            });
        } else {
            textInstructionsOrLink.setText(R.string.instructions);
            buttonLoginLogout.setText(R.string.login);
            buttonLoginLogout.setOnClickListener(new OnClickListener() {
                public void onClick(View view) { onClickLogin(); }
            });
        }
    }

    private void onClickLogin() {
        Session session = Session.getActiveSession();
        if (!session.isOpened() && !session.isClosed()) {
            session.openForRead(new Session.OpenRequest(this).setCallback(statusCallback));
        } else {
            Session.openActiveSession(this, true, statusCallback);
        }
    }

    private void onClickLogout() {
        Session session = Session.getActiveSession();
        if (!session.isClosed()) {
            session.closeAndClearTokenInformation();
        }
    }

    private class SessionStatusCallback implements Session.StatusCallback {
        @Override
        public void call(Session session, SessionState state, Exception exception) {
            updateView();
        }
    }
}

在我的代码中，我尝试使用facebook在此处提供的URL获取用户个人资料pictrue：

https://developers.facebook.com/docs/reference/api/using-pictures/

在我的活动结果中，我有以下代码：

ImageView user_picture;
                    user_picture= (ImageView)findViewById(R.id.userpicture);
                    URL img_value = null;
                    try {
                        img_value = new URL("https://graph.facebook.com/shaverm/picture?type=normal");
                    } catch (MalformedURLException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                    Bitmap mIcon1 = null;
                    try {
                        mIcon1 = BitmapFactory.decodeStream(img_value.openConnection().getInputStream());
                    } catch (IOException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                    user_picture.setImageBitmap(mIcon1);

                    super.onActivityResult(requestCode, resultCode, data2);

但是我得到了这个错误：

我也试过这个问题：

Android and Facebook: How to get picture of logged in User

此代码我被弃用了错误：

Facebook mFacebook = new Facebook(APP_ID);
// ... user logs in ...
//String jsonUser = mFacebook.request("me/picture"); // throws error
String jsonUser = mFacebook.request("me");
JSONObject obj = Util.parseJson(jsonUser);
String facebookId = obj.optString("id");
String name = obj.optString("name");

您正在获取主线程异常的网络。因此，尝试在asynctask中执行您的过程或尝试使用

if (android.os.Build.VERSION.SDK_INT > 9) {
                StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
                StrictMode.setThreadPolicy(policy);
            }
在onCreate();

之后的setContentView(R.layout.xxx)中
