Samsung IAP - checking if an item is bought upon start up? - in-app-purchase

Question

I just do not know how to use Samsung IAP!
I come from Google Play IAP where the IAP was pretty easy to implement. I took out all of that stuff and I started integrating the Samsung stuff. Now, I can make purchases, but what I don't understand is how to check if an item has been purchased.
My game has ads, and I have one non-consumable set up that will disable ads forever if purchased. As stated, I can purchase and disable the ads - the issue is that I want to check if that item has been purchased upon each start up, maybe in the on create. Otherwise, the ads come back upon the app closing down (I can use shared preferences, but if the app is uninstalled, the issue remains).
This is how it works in Google Play IAP. I have gone through the docs and the one example, and I understand that I can use doGetInboxList to see what items have been purchased.
However, as in the sample, this just asks for the group ID (no individual items), and even then, just says what and what isn't purchased in a list view. I have searched the code, but I can't even find where this is set. Regardless, programmitically I just want something.. anything! A boolean. Is this item with this id bought or not - yes or no. True or false. Have I missed something? Any help would be appreciated!

You are close.
Take that sample from InboxListActivity and apply to your activity:
public class YourStartUpActivity extends Activity implements OnGetInboxListener
{
private String mItemGroupId = "100000xxxxxx";
private int mIapMode = SamsungIapHelper.IAP_MODE_TEST_SUCCESS;
private int mStartNum = 1;
private int mEndNum = 15;
private String mStartDate = "20140101";
private String mEndDate = "30140101";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//do your initializations here
SamsungIapHelper iapHelper = SamsungIapHelper.getInstance( this, mIapMode );
iapHelper.getItemInboxList( mItemGroupId,
mStartNum,
mEndNum,
mStartDate,
mEndDate,
this );
}
#Override
public void onGetItemInbox
(
ErrorVo _errorVo,
ArrayList<InboxVo> _inboxList
)
{
if( _errorVo != null &&
_errorVo.getErrorCode() == SamsungIapHelper.IAP_ERROR_NONE )
{
// TODO When inbox list has been loaded successfully,
// processes here.
if( _inboxList != null && _inboxList.size() > 0 )
{
//if you only have 1 item, you can assume that item is purchased, otherwise
//go over the _inboxList and check
//that user has purchased the correct item
}
}
}
}
Hope it helps
