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是它给了我错误 java.lang.UnsupportedOperationException：Session：尝试为具有挂起的会话请求新权限请求。 当我第一次和第二次运行时它没有给我这个例外，我使用最新的fb SDK进行集成。我会发给我代码。

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);

}

尝试为具有待处理请求的会话请求新权限.Android
