  • Is this the exception? Show us the exception. – Samuel Dec 29 '14 at 10:38
  • What is the stacktrace of the exception? Did you debug the application to see when and why it happens? Show us your code. – msporek Dec 29 '14 at 10:41
  • The GnException ErrorDescription is "Local data store not found", the ErrorCode is 279250176 and the ErrorApi is "gnsdk_lookup_local_storage_info_count" The code is the "musicid_album_text" GNSDK sample. – Frédéric Schmidt Dec 29 '14 at 10:41

You cannot use the local mode, you need a special license file for that.

Make sure to understand there is a difference between using a local sqlite cache for queries, which is going to work for you and having a local metadata database, which you will not be able to use (except if you have a commercial agreement to do so).

  • Hello, I don't have problem with my licence file. It's the online mode who required a specific licence. A registration it's required to online use. – Frédéric Schmidt Jan 10 '15 at 12:48
  • As you can see in the output log, the SDK is trying to make local lookups using a local database that you do not have: lookup_local_storage_helpers.c[219] Failed to open storage group: 'gn_mdata.gdb', makes sense? – Jonx Jan 13 '15 at 18:43
  • Yes, I know, but in online mode, I don't have the licence for online mode then what's the correct mode to run sample ? – Frédéric Schmidt Jan 14 '15 at 10:50
  • The correct mode is online. You cannot run it offline. Go here to create an account: https://developer.gracenote.com/ There you will be able to generate the licence file you need. – Jonx Jan 19 '15 at 18:23
  • Yes, I am registered on the site, I create a licence file for my application. This file, I use in my code but with the online mode, I have a error message who said I don't have the right licence for this using. :-( – Frédéric Schmidt Jan 23 '15 at 08:12
  • Ok, let's be a little concrete ;) What's the client id? only post the first part of the client id, the one before the : or the - Have you modified the sample? I'll try on my side if you want. What is your username on the developer portal? – Jonx Jan 26 '15 at 22:41
