但它一直无法获取设备令牌(couldNotFetchDeviceReferenceToken)

当初始化库时,我得到了按钮,但是当我在按钮上多次单击时,onClickListeneren只获得第一次点击(而在onClick中没有做任何事情).

获取以下错误：

12-19 16:59:41.731: ERROR/Error(4745): Authentication Failed,button not enabled.
12-19 16:59:41.739: ERROR/paypal(4745): FAIL receiving Token
12-19 17:00:06.544: ERROR/PP Init(4745): INITIALIZE_FAILURE@H_301_9@ 
 
有谁知道我做错了什么？

在onCreate中：
