Android 只能通过一个帐户登录，在facebook上登录时不使用其他id

在我的应用程序中，我可以通过我的facebook id登录，如果我输入另一个id，它不会像我的id那样获取数据。我不明白问题出在哪里。当我输入另一个id时，它会显示正在加载，之后只会看到空白的facebook页面

main活动

public class MainActivity extends Activity {
    Facebook fb;
Button login,getData,logout;

     app_id= getString(R.string.app_id);
     fb= new Facebook(app_id);
        login=(Button) findViewById(R.id.login);
        logout=(Button) findViewById(R.id.logout);
        getData=(Button) findViewById(R.id.getData);
        // ig= (ImageView) findViewById(R.id.profile_pic);

                }
            });

getData.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View v) {
        getProfileInformation();
    }

当你在Facebook上创建应用程序时。您可能已经启用了测试和沙箱模式，如图所示。您需要禁用它

注意：不要查看其他设置。这是web应用程序，同样，移动应用程序也有沙盒选项。

我也有同样的问题。我是这样修好的

转到Facebook开发者页面

应用程序-->“YourApp”->“状态和查看”->“启用”（“是否要使此应用程序及其所有实时功能对公众可用？”）

像这样

您的代码没有更新为最新的Facebook SDK 3.8，现在Facebook提供了登录、共享、从Facebook导入照片等默认类。请点击此链接

你能告诉我你遇到了什么错误吗？@Rahul Gupta我没有收到任何错误，首先它不会注销，如果我在重新安装应用程序后尝试输入另一个id，它会获取id和密码，但在那之后，只有带有facebook标题的空白facebook页面才可见，而如果我在登录后输入我的id，它会显示我的个人资料图片和我的name@Himani试试我的答案。@anuruddhika是的，它有用。。谢谢：）@anuruddhika你能告诉我注销时有什么问题吗。。请@Mehul Joisar在我的高级设置中没有字段名沙盒模式。我认为版本不同
