https://developer.android.com/google/play/billing/billing_integrate.html#QueryPurchases

Bundle ownedItems = mService.getPurchases(3, getPackageName(), "inapp", null); 
int response = ownedItems.getInt("RESPONSE_CODE"); 
if (response == 0) { 
    ArrayList<String> ownedSkus = 
     ownedItems.getStringArrayList("INAPP_PURCHASE_ITEM_LIST"); 
    ArrayList<String> purchaseDataList = 
     ownedItems.getStringArrayList("INAPP_PURCHASE_DATA_LIST"); 
    ArrayList<String> signatureList = 
     ownedItems.getStringArrayList("INAPP_DATA_SIGNATURE_LIST"); 
    String continuationToken = 
     ownedItems.getString("INAPP_CONTINUATION_TOKEN"); 

    for (int i = 0; i < purchaseDataList.size(); ++i) { 
     String purchaseData = purchaseDataList.get(i); 
     String signature = signatureList.get(i); 
     String sku = ownedSkus.get(i); 

     // do something with this purchase information 
     // e.g. display the updated list of products owned by user 
    } 

    // if continuationToken != null, call getPurchases again 
    // and pass in the token to retrieve more items 
}
