在Facebook上加我这样的权限
In facebook I added the permission like this
推荐答案
电子邮件字段是不是从我的终点返回一个标准，所以你需要一个特定的请求使用Request类拿来。
The email field is not a standard one that is returned from the me endpoint, so you will need a specific Request to fetch it using the Request class.
使用此<一个href=\"https://github.com/facebook/facebook-android-sdk/blob/master/facebook/src/com/facebook/Request.java#L278\" rel=\"nofollow\">https://github.com/facebook/facebook-android-sdk/blob/master/facebook/src/com/facebook/Request.java#L278
设置你想要的，喜欢它的字段：
Set the fields on it that you want, like:
// Make sure the user is logged in first
Request meRequest = Request.newMeRequest(Session.getActiveSession(), yourCallback);
Bundle parameters = new Bundle();
// The fields you want in comma separated list
parameters.putString(fields, "id,name,email");
meRequest.setParameters(parameters);
meRequest.executeAsync();
您需要的电子邮件许可的作品，虽然之前。
You need the email permission before that works though.
您可以使用图形API探险以查看该图的要求应该表现。
You can use the graph api explorer to see for the graph request should behave.
