我是安卓新手。我已经在我的应用程序中集成了 facebook，它可以正常工作。当我想分享我的内容时，突然出现上述错误。如何解决这个问题请帮助我。

提前谢谢

我的 faceboobc.java 类代码如下

import com.example.shareslabfb.DialogError;
import com.example.shareslabfb.Facebook;
import com.example.shareslabfb.Facebook.DialogListener;
import com.example.shareslabfb.FacebookError;

import android.view.Window;
import android.widget.Toast;

public class Facebookc extends Activity{

    private static final String APP_ID = ".............";

        private static final String KEY = "facebook-credentials";

    private Facebook facebook;
    private String messageToPost;


    public boolean saveCredentials(Facebook facebook) {
        Editor editor = getApplicationContext().getSharedPreferences(KEY, Context.MODE_PRIVATE).edit();
        editor.putString(TOKEN, facebook.getAccessToken());
        editor.putLong(EXPIRES, facebook.getAccessExpires());
        return editor.commit();
    }

    public boolean restoreCredentials(Facebook facebook) {
        SharedPreferences sharedPreferences = getApplicationContext().getSharedPreferences(KEY, Context.MODE_PRIVATE);
        facebook.setAccessToken(sharedPreferences.getString(TOKEN, null));
        facebook.setAccessExpires(sharedPreferences.getLong(EXPIRES, 0));
        return facebook.isSessionValid();
    }

    super.onCreate(savedInstanceState);

    facebook = new Facebook(APP_ID);
