How to get purchase status for specific list of items in Google Play IAB Version 3?

Question

I have a problem with getting purchase status for my in app products. In my app I have hundreds of of in-app items and I just need to query 10 at the time. On my current account I have 20+ test purchased items (don't know the exact number) that I managed to buy.

The problem is if I pass only 1 sku to the queryInventoryAsync method I get 10-15 purchases back in the response and If I try to pass 10 skus I get developer error (5).

I use (not actual code):

List<String> skus = new ArrayList<String>();
skus.add("com.myapp.app_key.inappgroup.itemnumber");
mIabHelper.queryInventoryAsync(true, skus, new IabHelper.QueryInventoryFinishedListener()...

What am I doing wrong?

If I try to use

mIabHelper.getService().getSkuDetails((3, context.getPackageName(), "inapp", querySkus);

I get the correct number of sku details back, but that does not help me much since I need to get purchase status.

Hope I make some sense & thanks for the help!

I managed to resolve my issue with a fix described here: Android IAB: "Error refreshing inventory (querying prices of items)" Developer Error

Just that in my case, the sku limit was 8 skus. Now it takes a little longer, but I get all the information I requested.
