Facebook要求写权限

Question

我遇到了问题。在登录期间，我要求读取权限，这似乎工作正常，但每当我想分享的东西，我使用此方法来检查所需的权限：

public interface OnWritePermissionListener {
    public void result(boolean success);
}

public void askWritePermissions(final OnWritePermissionListener listener) {
    if (!getSession().getPermissions().containsAll(writePermissions)) {
        L.d("Requesting write permissions.");
        Session.NewPermissionsRequest newPermissionsRequest = new Session.NewPermissionsRequest(activity, writePermissions);
        newPermissionsRequest.setCallback(new StatusCallback() {
            @Override
            public void call(Session session, SessionState state, Exception exception) {
                L.d("Status callback for askWritePermissions. State: %s. Exception: %s.", state.name(), exception == null ? "none" : exception.toString());
                if (session.getPermissions().containsAll(writePermissions)) {
                    listener.result(true);
                } else {
                    listener.result(false);
                }
            }
        });
        getSession().requestNewPublishPermissions(newPermissionsRequest);
    } else {
        L.d("Write permissions already granted.");
        listener.result(true);
    }
    return;
}

writePermissions包含字符串条目：＆＃34; publish_actions＆＃34;

问题在于，当我调用此方法时，FB窗口只出现半秒钟然后消失，调用listener.result（false）。日志显示：

Status callback for askWritePermissions. State: OPENED_TOKEN_UPDATED. Exception: none.

任何想法我可能做错了什么？
