Question

我試圖用Facebook登錄來獲取用戶個人資料圖片。使用此代碼登錄到從例如Facebook的代碼，Facebook的

林：

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(); 
     } 
    } 
} 

在我的代碼我嘗試使用URL的Facebook給了這裏，以獲取用戶的個人資料禮品編號：

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

在我的活動結果，我有這樣的代碼：

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); 

但是我得到這個錯誤：

我也試過這個問題：

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

我得到廢棄的錯誤此代碼：

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");

您是在主讓網絡肆意的例外。因此，嘗試做你的過程中的AsyncTask或嘗試使用，

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

在onCreate()後setContentView(R.layout.xxx);
