【问题描述】：
我有一个为用户提供社交登录的启动页面。如果用户使用电子邮件地址登录，则可以在设置活动中连接到 Twitter。
我使用下面的代码在启动页面上登录用户，如果用户点击“与 Twitter 连接”，我在设置活动中使用相同的代码登录 Twitter。
我的问题是，一旦我授权该应用使用 Twitter，它会打开 Splash 页面而不是设置活动，因此无法验证用户身份。我 100% 确定我不会启动应该打开启动活动的意图。
致电startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(requestToken.getAuthenticationURL())));后
Twitter 身份验证网站出现，当我单击“允许”时，活动应该重新加载，但 Splash 活动会重新加载。启动应用程序时会打开启动画面，但我可以绕过这个吗？ （当在启动页面上登录时它显然可以正常工作，问题是为什么一旦从内部活动对用户进行身份验证后它会打开启动页面？）
