Answer 1

您应该查看解释GCM响应的GCM文档:http://developer.android.com/google/gcm/gcm.html#response并对401错误代码进行故障排除:http://developer.android. COM /谷歌/ GCM/gcm.html#auth_error

来自文档的描述:

身份验证错误您尝试用于发送邮件的发件人帐户无法进行身份验证.可能的原因是:

授权标头丢失或语法无效.

作为密钥发送的项目编号无效.

密钥有效但GCM服务已禁用.

请求源自服务器密钥IP中未列入白名单的服务器.

因此,我会检查以确保您正确设置了授权标头,并确保使用GCM正确设置Google Project编号并接受您的服务器IP.
