Android应用程序内计费Trivial Drive

Question

我正在进行像TrivialDrive这样的应用内购买.调用queryInventoryAsync:

 mHelper.queryInventoryAsync(mGotInventoryListener);

mGotInventoryListener:

IabHelper.QueryInventoryFinishedListener mGotInventoryListener = new IabHelper.QueryInventoryFinishedListener() {
    public void onQueryInventoryFinished(IabResult result, Inventory inventory) {

        String price = inventory.getSkuDetails(SKU_ALL_INCLUSILE).getPrice();
        Log.d("SKU", "price " + price);
    }
};

OnClick工作完美,我可以购买.但getPrice()方法产生NPE.请帮帮我!我想在ListView中显示SKU信息.

解决了!只需使用:

 mHelper.queryInventoryAsync(true, skuList, mGotInventoryListener);
