Google EMM API troubles

Good day! I have interest in Google Play EMM

I have created Device Policy Controller and created Work Profile. Created a Google Developers Console project and added EMM API. Created master service account. In master service account I obtained EMM token.

I have downloaded Google Play EMM API Client Library for Java. As I know, I just need to call something like

Enterprise enterprise = new Enterprise();
enterprise.setPrimaryDomain(primaryDomainName);
Enterprise result = androidEnterprise.enterprises()
   .enroll(authenticationToken, enterprise).execute();

EnterpriseAccount enterpriseAccount = new EnterpriseAccount();
enterpriseAccount.setAccountEmail(serviceAccountEmail);
androidEnterprise.enterprises().setAccount(result.getId(),
enterpriseAccount).execute();

First question - how do I add device(android phone) to master service account grammatically? If i was using Google Android for Work and Google system by default - i would use "Device Enrollment" application. But I have no idea how to do this in programming way.

Second one - in the sample there are such lines

// Optional: you might want to store the bound enterprise's info, but
// these details can always be retrieved with an Enterprises.List call.

Where do they store ? At Google servers? Am I right when I think that when I do enterprise.setPrimaryDomain(primaryDomainName); I get access to all enrolled customers?

Third - is there any NORMAL samples ? Or step by step howto? There is not a lot of information about all this after all ( Thank you.

Solution

Still You have same issue? Please let me know i think i can help you for enroll.

Change request like this:

Enterprise enterprise = new Enterprise();
enterprise.setPrimaryDomain(primaryDomainName);
enterprise.setId("Unique_EMM_ID"); //Which you will get from Google in mail
enterprise.setKind("androidenterprise#enterprise");

try{

      AndroidEnterprise.Enterprises.Enroll enroll = androidEnterprise.enterprises().enroll(authenticationToken, enterprise);
      enroll.setToken(token);

      Enterprise result = enroll.execute();

      EnterpriseAccount enterpriseAccount = new EnterpriseAccount();
      enterpriseAccount.setKind("androidenterprise#enterpriseAccount");
      enterpriseAccount.setAccountEmail(serviceAccountEmail);

      androidEnterprise.enterprises().setAccount(result.getId(), enterpriseAccount).execute();

   } catch (Exception e) {
        e.printStackTrace();
   }

Try like this. I hope this will help you.
