所以我的一个伙伴正在帮我测试我的应用程序。但是，在他获得允许或拒绝屏幕后，即使我们获得了访问代码，也不会让他实际登录应用程序。当我在他的Samsung Galaxy S6 Edge上运行应用程序时，运行对话框中会显示以下错误：

我不确定这是什么意思。如果我使用给定的访问令牌，我可以使用oAuth 2.0 playground并按正常方式继续。
答案 0 :(得分：0)
因此用户未连接到他的首选连接。他的首选连接是I/System.out: Connection Preference: wifi，他与4G连接。我添加了以下内容来检查它：
else {
Toast.makeText(getApplicationContext(), "You are not connected to your preferred connection." + "\n" +
"Please connect to your preferred connection to continue."
, Toast.LENGTH_LONG).show();
}
