java - Android上的Facebook OAuth

每次我在模拟器上测试我的应用程序时。 “ AppName发生错误。请稍后再试。”我已在清单.XML中启用了Internet访问。

这是我到目前为止的内容：

package com.xxxxxx;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.widget.TextView;

import com.facebook.android.DialogError;
import com.facebook.android.Facebook;
import com.facebook.android.Facebook.DialogListener;
import com.facebook.android.FacebookError;
import com.facebook.android.Util;

public class LunchtimeActivity extends Activity {

    Facebook facebook = new Facebook("xxxxxxxxxxxxxx");

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //setContentView(R.layout.main);

        facebook.authorize(this, new String [] {"user_location", "friend_location", "user_events", "friends_events"}, new DialogListener() {
            @Override
            public void onComplete(Bundle values) {}

            @Override
            public void onFacebookError(FacebookError error) {}

            @Override
            public void onError(DialogError e) {}

            @Override
            public void onCancel() {}
        });

        Bundle parameters = new Bundle();
        parameters.putString( "fields", "id,name" );

        try {
            String response = facebook.request( "me/friends", parameters );

            JSONObject json = Util.parseJson( response );

            JSONArray data = json.getJSONArray( "data" );

            for ( int i = 0; i < data.length(); i++ )
            {
                JSONObject friend = data.getJSONObject( i );

                String id = friend.getString( "id" );
                String name = friend.getString( "name" );
                Log.v("JSON", id);
                Log.v("JSON", name);
            }
        }
        catch (Exception e) {}
        catch (FacebookError f) {}

        TextView tv = new TextView(this);
        tv.setText("Hello, Android");
        setContentView(tv);
    }

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

        facebook.authorizeCallback(requestCode, resultCode, data);
    }
}

Logcat输出：

实际上，我只是使用Facebook本身为Android提供的Facebook SDK，但我无法使其正常工作。有任何想法吗？

最佳答案

您使用的是friend_location而不是friends_location

检查logcat的最后几行：


  05-01 02：21：01.601：调试/ Facebook-WebView（234）：Web视图加载URL：fbconnect：// success /？error = invalid_scope＆error_description =不支持+ scope％3A +％27friend_location ...


顺便说一句，最好将至少一些日志输出添加到public void onFacebookError(FacebookError error) {}和catch (Exception e) {} catch (FacebookError f) {}。它将为您（和我们）节省很多时间：）
