我用谷歌搜索了近半天，我找不到任何可以解决这个问题的例子。情况就是这样。用户在首次登录时会看到电子邮件请求并拒绝它。下次登录时，它会显示“您已经授权”它不会再次询问电子邮件请求，因为它被拒绝了。 我不希望用户转到设置并进行更改。有没有办法再次提出这个许可？ 请helppp

更新1：
在HelloFacebookSample（它带有sdk 3.8）当我更改私有静态最终字符串PERMISSION =“email”;它会问我，即使我现在不说是允许的。
但是，当我更改为我的应用程序ID时，它不再问了。它只是问了一次，就是这样。
我的应用ID不会被审核但我只是想要不需要任何额外审核的电子邮件信息。能否有人帮助我

针对SDK v4.1 +
进行了更新Set<String> permissions = AccessToken.getCurrentAccessToken().getPermissions();
if(permissions.contains("email")) {
// Continue your stuff.
} else {
GraphRequest request = new GraphRequest(
AccessToken.getCurrentAccessToken(),
"/me/permissions", null, HttpMethod.DELETE,
new GraphRequest.Callback() {
@Override
public void onCompleted(GraphResponse graphResponse) {
LoginManager.getInstance().logOut();
Toast.makeText(context, "Email permission is needed. Please try again.", Toast.LENGTH_LONG).show();
}
}
);
request.executeAsync();
}

似乎我找到了一个解决方案，即使它花了我钱，我将与所有人分享。
您必须在登录时检查权限，然后如果您发现此人不允许电子邮件，您必须撤消所有权限。在以前的那些他们也喜欢那样 How to revoke all Facebook permissions using Android SDK?
Session session = Session.getActiveSession();
new Request(session, "me/permissions", null, HttpMethod.DELETE,
new Request.Callback() {
public void onCompleted(Response response) {
Log.e("Complete", response.toString());
Toast.makeText(c.getApplicationContext(), "Erase Completely",
Toast.LENGTH_LONG).show();
// postStatusUpdate();
}
}).executeAsync();
