Android 无法将Aws Iot策略附加到证书

在这里，我想在aws iot中附上一份带有aws证书的保单。 对于此操作，我使用attachPrincipalPolicy（）函数。 但在'com.amazonaws:aws android sdk iot:2.6.29'sdk版本中不推荐使用此函数。 所以每次创建证书后，我都需要手动将策略附加到证书。 是否有其他方法将保单附加到aws证书？

参考：

附加原则政策

将指定的策略附加到指定的主体（证书） 或其他凭证）

注意：此API已弃用。请改用

 AttachPrincipalPolicyRequest policyAttachRequest = new AttachPrincipalPolicyRequest();
 policyAttachRequest.setPolicyName(AWS_IOT_POLICY_NAME);                            

 policyAttachRequest.setPrincipal(createKeysAndCertificateResult.getCertificateArn());                 
 mIotAndroidClient.attachPrincipalPolicy(policyAttachRequest);

更多信息

AWSIot awsIotClient=AWSIotClientBuilder.defaultClient（）；
awsIotClient.createPolicy（新的CreatePolicyRequest（）.withPolicyDocument（policy）.withPolicyName（policyName））；
awsIotClient.attachPolicy（新的AttachPolicyRequest（）.withPolicyName（policyName）。withTarget（“arn:aws:iot:：：cert/I此处指定的证书-->
policyAttachRequest.setPrincipal（createKeysAndCertificateResult.GetCertificateLearn（））；
并在此处附加策略-->
MioAndRoidClient.AttachPrincipalPolicyAttachRequest（policyAttachRequest）；
但它不起作用。策略和证书在那里。但是策略无法附加证书。
AttachPrincipalPolicyRequest attachPolicyReq = new AttachPrincipalPolicyRequest(); //in docs it called AttachPolicyRequest but it`s wrong
attachPolicyReq.setPolicyName("allAllowed"); //name of your IOTAWS policy
attachPolicyReq.setPrincipal(getIdRes.getIdentityId());
new AWSIotClient(credentialsProvider).attachPrincipalPolicy(attachPolicyReq);

AWSIot awsIotClient = AWSIotClientBuilder.defaultClient();
awsIotClient.createPolicy(new CreatePolicyRequest().withPolicyDocument(policy).withPolicyName(policyName));
awsIotClient.attachPolicy(new AttachPolicyRequest().withPolicyName(policyName).withTarget("arn:aws:iot:<region>:<client_ID>:cert/<certificate_ID"
