(Android™) Xero Build Hashtable of Account CodesTo create a new account, a unique and unused account Code would need to be selected. How do we know what account Codes already exist? One way of finding out is to download the complete set of Accounts every time. Another way is to download once, and keep a local hash table of the account Codes. This makes it possible to find a new and unused Code without having to continually fetch data from the Xero server. Note: Requires Chilkat v9.5.0.64 or greater.

CkStringBuilder sbXml = new CkStringBuilder(); success = rest.FullRequestNoBodySb("GET","/api.xro/2.0/Accounts",sbXml); if (success != true) { Log.i(TAG, rest.lastErrorText()); return; } // A 200 response is expected for actual success. if (rest.get_ResponseStatusCode() != 200) { Log.i(TAG, sbXml.getAsString()); return; } // Iterate over the accounts, and build a Hashtable where the // key is the account Code, and the value is the XML record for the account.
