登录后的Facebook的Andr​​oid SDK不公开会议 [英] Facebook Android SDK does not open Session after login

问题描述

1）出现这个问题很多次，awnser总是你错了键哈希。

1) This question appears many times and the awnser is always "you have the wrong Key Hash".

2）的Facebook的文件告诉我们使用这个code，让我们的密钥散列：

2) Facebook documentation tells we to use this code to get our Key Hash:

keytool -exportcert -alias MyKeyAlias -keystore path\to\my\Key | openssl sha1 -binary | openssl base64

3）好了，这给了我那个键：-1-基********** Q3A

3) Ok, this gives me that key: 1yl**********Q3A

当我尝试登录，我得到了以下信息：     com.facebook.http.protocol.ApiException：（＃404）主要散XHA ********** Q10不匹配任何存储的密钥散列

When I try to login, I got the following message: com.facebook.http.protocol.ApiException: (#404) Key hash XHA**********q10 does not match any stored key hashes.

4）然后，我复制并粘贴XHA ********** Q10在我的应用程序设置，那不是我的钥匙要么。

4) Then I copy and paste the XHA**********q10 on my app settings and thats not my key either.

5）所以，我读这是一个code，让你正确的密钥散列文件。这code：

5) So, I read on documentation that was a code that gives you the correct Key Hash. This code:

// Add code to print out the key hash
try {
    PackageInfo info = getPackageManager().getPackageInfo(
            "com.facebook.samples.hellofacebook", 
            PackageManager.GET_SIGNATURES);
    for (Signature signature : info.signatures) {
        MessageDigest md = MessageDigest.getInstance("SHA");
        md.update(signature.toByteArray());
        Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
        }
} catch (NameNotFoundException e) {

} catch (NoSuchAlgorithmException e) {

}

它的工作！给了我这个哈希值：+ HA ********** Q0 =

It worked! Gave me this hash: +HA**********q0=

6）我把应用程序设置最后一个散列。是的，我现在可以连接！但是现在我无法打开会话！

6) I put this last hash on app settings and YES, now I can connect! BUT, now I can't open a Session!!!

我用下面的code：

public class FBActivity extends Activity {

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.my_view);

        System.out.println("Start Facebook login");
        Session.openActiveSession(this, true, new Session.StatusCallback() {
            public void call(Session session, SessionState state, 
                                              Exception exception) {
                System.out.println("Call");
                if (session.isOpened()) {
                    System.out.println("Open");
                    Request.newMeRequest(session, new Request.GraphUserCallback() {
                        public void onCompleted(GraphUser user, Response response) {
                            System.out.println("Complete");
                            if (user != null) {
                                System.out.println(user.getName());

                            } else {
                                System.out.println("User NULL");
                            }
                        }
                    }).executeAsync();
                } else {
                System.out.println("Not open");
            }

        });
    }
}

和日志是：

开始的Facebook登录

"Start Facebook Login

呼叫

不公开

呼叫

不开

我不知道我还能做什么，因为我已经有正确的密钥散列，我可以做的登录。

I don't know what else can I do, since I already have the correct Key Hash and I can make the login.

推荐答案

我想通了：

下面的方法失踪了。只需将它添加和一切工作。

The following method was missing. Just added it and everything worked.

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
}
