Android 应用程序无法连接到服务器

Question

我的 Android 应用程序曾经能够通过 API 连接到 Facebook 服务器，但现在由于某种原因无法连接。我不断在我的日志中收到此消息 cat

D/Facebook-authorize(417): Login failed: com.facebook.android.DialogError: The connection to the server was failed.

我读过很多与此相关的堆栈溢出问题，但没有答案。我希望有人能帮助我解决这个问题。谢谢你！

这是我的一些代码，其中我的应用程序 ID 已被编辑掉

public class BreadcrumbsActivity extends Activity {

static Facebook facebook = new Facebook("*************");
String FILENAME = "AndroidSSO_data";
static SharedPreferences mPrefs;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    /*
     * Get existing access_token if any
     */
    mPrefs = getPreferences(MODE_PRIVATE);
    String access_token = mPrefs.getString("access_token", null);
    long expires = mPrefs.getLong("access_expires", 0);
    if(access_token != null) {
        facebook.setAccessToken(access_token);
    }
    if(expires != 0) {
        facebook.setAccessExpires(expires);           
    }

    /*
     * Only call authorize if the access_token has expired.
     */
    if(!facebook.isSessionValid()) {

        facebook.authorize(this, new String[] {"user_likes", "user_photos", "email", "offline_access", "publish_actions"}, new DialogListener() {
            @Override
            public void onComplete(Bundle values) {
                SharedPreferences.Editor editor = mPrefs.edit();
                editor.putString("access_token", facebook.getAccessToken());
                editor.putLong("access_expires", facebook.getAccessExpires());
                editor.commit();

                Toast.makeText(getApplicationContext(),
                        "Login Succesful.",
                        Toast.LENGTH_LONG).show();

                Intent intent = new Intent(BreadcrumbsActivity.this, MainMenu.class);                   
                BreadcrumbsActivity.this.startActivity(intent);
            }

            @Override
            public void onFacebookError(FacebookError error) {
                Toast.makeText(getApplicationContext(),
                        "Login Failed.",
                        Toast.LENGTH_LONG).show();

                Intent intent = new Intent(BreadcrumbsActivity.this, MainMenu.class);                   
                BreadcrumbsActivity.this.startActivity(intent);
            }

            @Override
            public void onError(DialogError e) {}

            @Override
            public void onCancel() {}
        });
    }
}


@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    facebook.authorizeCallback(requestCode, resultCode, data);
}

}

错误 - 417 期望失败

417状态码表示服务器无法正常
完成请求。发送到服务器的标头之一，
“Expect”标头，表示服务器无法满足的期望。
