我使用“Parse”为 android 的 facebook 集成制作了一个简单的程序，我使用了以下代码，但显示异常，我的代码和 logcat 如下所示：

main.java

包 com.example.facbk;

import com.facebook.android.AsyncFacebookRunner;
import com.facebook.android.Facebook;
import com.parse.LogInCallback;
import com.parse.Parse;
import com.parse.ParseFacebookUtils;
import com.parse.ParseUser;
import android.net.ParseException;
import android.os.Bundle;
import android.provider.SyncStateContract.Constants;
import android.app.Activity;
import android.content.Intent;
import android.content.SharedPreferences;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class MainActivity extends Activity {
    private static String APP_ID =" 454641867918042";
    private Facebook facebook;
    private AsyncFacebookRunner mAsyncRunner;
    String FILENAME = "AndroidSSO_data";
    Button login;
    private SharedPreferences mPrefs;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Parse.initialize(this, "454641867918042", "aWEd6rRA18hQJNVueCzeVUqqPkkDKAxp8moP3IP");// Try by Adding this method before ParseFacebookUtils.initialize()
        ParseFacebookUtils.initialize("454641867918042");
        setContentView(R.layout.activity_main);
        System.out.println("hello login");
        ParseFacebookUtils.logIn(this, new LogInCallback() {

            @Override
            public void done(ParseUser user, com.parse.ParseException arg1) {
                // TODO Auto-generated method stub
                 if (user == null) {
                      Log.d("MyApp", "Uh oh. The user cancelled the Facebook login.");
                    } else if (user.isNew()) {
                      Log.d("MyApp", "User signed up and logged in through Facebook!");
                    } else {
                      Log.d("MyApp", "User logged in through Facebook!");
                    }
            }
            });

    }
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
      super.onActivityResult(requestCode, resultCode, data);
      ParseFacebookUtils.finishAuthentication(requestCode, resultCode, data);
    }

}

我不知道它会起作用还是不试试：打电话Parse.initialize()

您在 onCreate 中的代码应该是

super.onCreate(savedInstanceState);
Parse.initialize(this, Constants.APPLICATION_ID, Constants.CLIENT_KEY);// Try by Adding this method before ParseFacebookUtils.initialize()
ParseFacebookUtils.initialize("454641867918042");
setContentView(R.layout.activity_main);

编辑：

还要检查 AndroidManifest.xml 中的 Internet 权限

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

编辑：

将以下添加到您的AndroidManifest.xml

<activity
    android:name="com.facebook.LoginActivity"
     >
</activity>

显然，您已经为非fb 请求调用了 ParseFacebookUtils.finishAuthentication() 。阅读：https ://www.parse.com/questions/nullpointerexceptions-from-the-facebook-authentication

另一个原因可能是您使用的 fb sdk 3.0.2 已更改此部分并且 parse 不知道如何使用它。我在上面的链接中对此进行了评论。

尝试使用这个：

/* This constant is private in new fb sdk 3.0.2, this is why we use it this way. */
private final static int DEFAULT_FACEBOOK_AUTH_ACTIVITY_CODE = 32665;

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == FB_HACK_CODE && data != null)
            ParseFacebookUtils.finishAuthentication(requestCode, resultCode, data);
        super.onActivityResult(requestCode, resultCode, data);
}
