我在Android InApp计费v3上面临一个问题.我在playstore中创建了一个托管的inapp产品,我需要从多个设备上多次购买.为此,我正在两个不同的设备上测试应用程序.我没有在本地服务器上保留任何购买数据.因此,每当我需要再次购买该项目时,我将查询该项目以获得购买状态,并且如果该项目被购买,我将使用该项目并将再次调用购买功能.我正在详细说明我的错误情况

1. 在第一台设备上,我完成了付款,并获得了成功结果.
2. 在同一台设备上,如果我查询购买详情,它会给出确切的信息.
3. 如果我在第二个设备上查询的话.它给人的 inventory.hasPurchase(sku)是虚假和 inventory.getPurchase(sku)为空.

谷歌搜索时,我发现这与Google Playstore缓存有关.执行此操作后,手动缓存清除,我按预期获得结果.任何人都可以指导我上述问题.

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

            if (result.isFailure()) {
                invokePurchaseError(ResponseCode.FAILED_TO_QUERY_INVENTORY, result.toString());

            }
            else{

                if(mActionCode == RC_REQUEST_FOR_QUERYING){
                    boolean mIsPurchased = false;
                    Log.e("hasPurchase",  inventory.hasPurchase(mSku)+"");
                    Log.e("getPurchase",  inventory.getPurchase(mSku)+"");

                    if( inventory.hasPurchase(mSku)){
                        mPurchaseStatus = inventory.getPurchase(mSku);
                        mIsPurchased = (mPurchaseStatus != null && verifyDeveloperPayload(mPurchaseStatus));
                        if(mPurchaseStatus!=null){
                            mPurchaseStatus.getOriginalJson());
                        }
                        else{
                            //Not purchased
                        }

                    }

                }
        }
    };

我正在尝试为我的应用程序实现多点触控放大和缩小功能.我的应用程序是查看图像的幻灯片.我试图通过http://www.zdnet.com/blog/burnette/how-to-use-multi-touch-in-android-2-part-6-implementing-the-链接实现多点触控缩放功能. pinch-zoom-gesture/1847,它实际上是一个很好但我需要控制放大和缩小.即我想实现缩放的最大和最小限制.任何人都可以帮我解决这个问题.还要提前感谢调查这个问题.

我在解码json字符串时遇到了困难.下面是我的json字符串:

{
    "udeals":"[{\"vName\":\"bussinessname3\",\"vAddress\":\"address3\",\"vState\":\"Kerala\",\"vZip\":\"232\",\"vCountry\":\"Algeria\",\"id\":\"3\",\"dealCategoryID\":\"2\",\"dealCaption\":\"deal3\",\"dealurl\":\"http:\\/\\/192.168.0.8\\/ppppp\\/deals\\/deal3-3\\/\",\"dealImage\":\"http:\\/\\/192.168.0.8\\/ppppp\\/images\\/deals\\/thumb390x256\\/Duizl1.jpg\",\"dealPrice\":\"50.00\",\"dealCost\":\"100.00\",\"dealSave\":-50,\"dealOfferRate\":\"50.00\",\"jsDeadLine\":{\"seconds\":0,\"minutes\":0,\"hours\":0,\"mday\":5,\"wday\":3,\"mon\":1,\"year\":2011,\"yday\":4,\"weekday\":\"Wednesday\",\"month\":\"January\",\"0\":1294165800},\"unlockedStamp\":{\"seconds\":53,\"minutes\":56,\"hours\":18,\"mday\":5,\"wday\":3,\"mon\":1,\"year\":2011,\"yday\":4,\"weekday\":\"Wednesday\",\"month\":\"January\",\"0\":1294234013},\"description\":\"Google URL Shortener at goo.gl is used by Google products to create short URLs that can be easily shared, tweeted, or emailed to friends.\"},{\"vName\":\"bussinessname20010\",\"vAddress\":\"address20010\",\"vState\":\"Kerala\",\"vZip\":\"232\",\"vCountry\":\"Argentina\",\"id\":\"20010\",\"dealCategoryID\":\"2\",\"dealCaption\":\"deal20010\",\"dealurl\":\"http:\\/\\/192.168.0.8\\/ppppp\\/deals\\/deal20010-20010\\/\",\"dealImage\":\"http:\\/\\/192.168.0.8\\/ppppp\\/images\\/deals\\/thumb390x256\\/oCcfTj.jpg\",\"dealPrice\":\"50.00\",\"dealCost\":\"100.00\",\"dealSave\":-50,\"dealOfferRate\":\"50.00\",\"jsDeadLine\":{\"seconds\":0,\"minutes\":0,\"hours\":0,\"mday\":28,\"wday\":2,\"mon\":12,\"year\":2010,\"yday\":361,\"weekday\":\"Tuesday\",\"month\":\"December\",\"0\":1293474600},\"unlockedStamp\":{\"seconds\":53,\"minutes\":56,\"hours\":18,\"mday\":5,\"wday\":3,\"mon\":1,\"year\":2011,\"yday\":4,\"weekday\":\"Wednesday\",\"month\":\"January\",\"0\":1294234013},\"description\":\"this is\"}]"
}

任何人都可以给我一个解决方案,如何在Android中解析这个...
