如何在facebook SDK Android中获取用户的Facebook个人资料图片 [英] How to get facebook profile picture of user in facebook SDK Android

问题描述

我使用的是Facebook 3.6 sdk。我想从图形用户获取个人资料图片，上次我有图像，但现在返回空位图。

我使用以下代码 p>

  private void onSessionStateChange（Session session，SessionState state，
异常异常）{
 if（session.isOpened ）{
 Request.newMeRequest（session，new Request.GraphUserCallback（）{
 @Override 
 public void onCompleted（GraphUser user，Response response）{
 if（user！= null）{
 try {
 URL imgUrl = new URL（http://graph.facebook.com/
 + user.getId（）+/ picture？type = large ）; 
 
 InputStream in =（InputStream）imgUrl.getContent（）; 
位图位图= BitmapFactory.decodeStream（in）; 
 //位图位图= B itmapFactory.decodeStream（imgUrl //尝试这也
 //。openConnection（）。getInputStream（））; 
} catch（Exception e）{
 e.printStackTrace（）; 
} 
} 
} 
}）。executeAsync（）; 
} 
} 
  

当我使用直接链接然后它的工作。 p>

  imgUrl =新的URL（https://fbcdn-dragon-a.akamaihd.net/hphotos-ak-ash3/t39。 2365-6 / 851558_160351450817973_1678868765_n.png）; 
  

我也是这样也 Graph API参考

解决方案

自动重定向原始和重定向协议相同时，会自动工作。

所以，尝试加载 https 而不是 http ： https://graph.facebook.com/USER_ID/picture ;因为图片的网址是 https://fbcdn-profile-a.akamaihd.net/ 。 ...

然后 BitmapFactory.decodeStream 将再次工作。

I used facebook 3.6 sdk . i want to get profile picture from graph user , last time i got image but now it returns null Bitmap.

I used following code

private void onSessionStateChange(Session session, SessionState state,
            Exception exception) {
        if (session.isOpened()) {
            Request.newMeRequest(session, new Request.GraphUserCallback() {
                @Override
                public void onCompleted(GraphUser user, Response response) {
                    if (user != null) {
                        try {
                            URL imgUrl = new URL("http://graph.facebook.com/"
                                    + user.getId() + "/picture?type=large");

                            InputStream in = (InputStream) imgUrl.getContent();
                            Bitmap  bitmap = BitmapFactory.decodeStream(in);
                            //Bitmap bitmap = BitmapFactory.decodeStream(imgUrl      // tried this also
                            //.openConnection().getInputStream());
                        } catch (Exception e) {
                            e.printStackTrace();
                        }
                    }
                }
            }).executeAsync();
        }
    }

When i use direct link then it works.

imgUrl = new URL("https://fbcdn-dragon-a.akamaihd.net/hphotos-ak-ash3/t39.2365-6/851558_160351450817973_1678868765_n.png");

i refered this also Graph API Reference

解决方案

Auto redirection works automatically when original and redirected protocols are same.

So, try to load images from https instead of http : "https://graph.facebook.com/USER_ID/picture"; since image's url is "https://fbcdn-profile-a.akamaihd.net/...."

Then BitmapFactory.decodeStream shall work again.
