检查应用内购买

Question

Following instructions from: https://developer.android.com/training/in-app-billing/purchase-iab-products.html under Query Purchased Items, I am checking for purchased items.

My code looks like this:

    private void lookForPurchases() {
    IabHelper.QueryInventoryFinishedListener lookForPurchasesListener = new IabHelper.QueryInventoryFinishedListener() {
        public void onQueryInventoryFinished(IabResult result, Inventory inventory) {
            if (result.isFailure()) {
                Log.e(TAG, "Error checking for purchases:" + result.toString());
            }
            else {
                Log.d(TAG, "Processing purchases." + inventory.toString());
                if(inventory.hasPurchase(SKU_LEXCOINS_100)){
                    Purchase purchase = inventory.getPurchase(SKU_LEXCOINS_100);
                    consumeCoinPurchase(purchase);
                }
                if(inventory.hasPurchase(SKU_LEXCOINS_550)){
                    Purchase purchase = inventory.getPurchase(SKU_LEXCOINS_550);
                    consumeCoinPurchase(purchase);
                }
                if(inventory.hasPurchase(SKU_LEXCOINS_1200)){
                    Purchase purchase = inventory.getPurchase(SKU_LEXCOINS_1200);
                    consumeCoinPurchase(purchase);
                }
            }
        }
    };

    Log.i(TAG, "Looking for purchases");
    if(inAppBillingHelper == null) {
        Log.e(TAG, "Null preventing query inventory");
    } else {
        try {
            inAppBillingHelper.queryInventoryAsync(lookForPurchasesListener);
        } catch (IabHelper.IabAsyncInProgressException ex) {
            Log.e(TAG, "Error retrieving purchases.", ex);
        }
    }
}

In the log, though, the last thing I get is "Looking for purchases" with nothing following. It looks like I should get something on any branch, so, does anyone see what I'm doing wrong?

No errors or anything, it just never seems to come back.

The problem was on the line handler.post deep in IabHelper (Google Code) where it was executing my callback I was passing in. The handler.post was getting called, buy my callback never was. I'm not sure how that happened.

I replaced the handler.post with a AsyncTask and posted the call of my callback in the onPostExecute method to get it run on the UI thread. This appears to have solved my problem.
