securityToken如何获取?

android端在构造OSSCredentialProvider时需要securityToken字段,请问我该如何获取该字段?

调用Oss#PutObjectRequest()收到的回调

<Error>
  <Code>InvalidAccessKeyId</Code>
  <Message>The OSS Access Key Id you provided does not exist in our records.</Message>
  <RequestId>5D5CB912CF4DC154736C1BFA</RequestId>
  <HostId>pbl-chess.oss-cn-beijing.aliyuncs.com</HostId>
  <OSSAccessKeyId>fWykJRhvaOf3XEz9</OSSAccessKeyId>
</Error>

android端部分代码:
