尝试为具有挂起请求的会话请求新权限.人造人

Question

我已经实现了fb集成，我通过设置一些权限来获取用户详细信息，但它给了我错误java.lang.UnsupportedOperationException：会话：尝试为具有挂起请求的会话请求新权限。当我第一次和第二次运行时，它没有给我这个异常，我正在使用最新的 fb SDK 进行集成。我会给我发布代码。

public class MainActivity extends Activity {
    Button loginbtn;
    Session session = Session.getActiveSession();
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        loginbtn = (Button)findViewById(R.id.loginbutton);

        loginbtn.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Intent intent = new Intent(MainActivity.this,FacebookLogin.class);
                startActivity(intent);
            }
        });
    }

使用 onActivityResult 方法更新活动会话。

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