如何做好恢复购买和获得产品是否购买或不？ [英] How to do restore purchase and get whether the Product is Purchase or not?

问题描述

我已经实现了应用程序内结算在我的Andr​​oid应用程序。
在code我用它如下：

I have implemented the in-App Billing in my android App. The code i use it as below :

onCreate方法：

oncreate method:

startService(new Intent(this, BillingService.class));
    System.out.println(" - - - - CHECK FOR THE PURCHASE PRODUCT - - - - ");
    BillingHelper.setCompletedHandler(mTransactionHandler);

处理程序是：

 public Handler mTransactionHandler = new Handler(){
    public void handleMessage(android.os.Message msg) {
        System.out.println("SEE FOR THE PRODUCTS PURCHASE OR NOT");

        Log.i(TAG, "Transaction complete");
        Log.i(TAG, "Transaction status: "+BillingHelper.latestPurchase.purchaseState);
        Log.i(TAG, "Item purchased is: "+BillingHelper.latestPurchase.productId);

        // For Premium Pro Purchase
        if(BillingHelper.latestPurchase.productId == "premium_pro"){
            if(BillingHelper.latestPurchase.isPurchased()){
                System.out.println("START OPENING PREMIUM_PRO_BUY CONTENT");
                myPrefs = getApplicationContext().getSharedPreferences("myPrefs",MODE_WORLD_WRITEABLE);
                prefsEditor = myPrefs.edit();                 
                prefsEditor.putBoolean("PREMIUM_PRO_BUY", true); // value to store                 
                prefsEditor.commit(); 
                PREMIUM_PRO_BUY = true;
                System.out.println("NOW.. . .  PREMIUM_PRO_BUY is as PURCHASED. :-)");
                System.out.println("FINISH TO OPENING BLOCK CONTENT");
                //  showItem();
            }
        }

        // For Feature Upgrade Purchase
        if(BillingHelper.latestPurchase.productId == "feature_upgrade"){
            if(BillingHelper.latestPurchase.isPurchased()){
                System.out.println("START OPENING FEATURE_UPGRADE_BUY CONTENT");
                myPrefs = getApplicationContext().getSharedPreferences("myPrefs",MODE_WORLD_WRITEABLE);
                prefsEditor = myPrefs.edit();                 
                prefsEditor.putBoolean("FEATURE_UPGRADE_BUY", true); // value to store                 
                prefsEditor.commit(); 
                FEATURE_UPGRADE_BUY = true;
                System.out.println("NOW.. . .  FEATURE_UPGRADE_BUY is as PURCHASED. :-)");
                System.out.println("FINISH TO OPENING BLOCK CONTENT");
                //  showItem();
            }
        }






    };
};

和在按钮单击我的code是：

And in Button click my code is:

//      CODE TO GET PURCHASED
        if(BillingHelper.isBillingSupported()){

            BillingHelper.requestPurchase(getApplicationContext(), "feature_upgrade"); // MY OWN

        } else {
            Log.i(TAG,"Can't purchase on this device");
            Toast.makeText(getApplicationContext(), "Please check internet and make sure that you have latest GooglePlay App in your Device.", Toast.LENGTH_LONG).show();
        }

现在，当我点击恢复购买按钮，我想看看哪些产品是购买与否。这样，我有什么做的？

Now when i click on Restore Purchase Button, I want to see which Product is Purchase or not. So what should i have to do ??

我已经看到了这SO问题：<一href=\"http://stackoverflow.com/questions/8465738/android-in-app-billing-restore-transaction\">this,和<一个href=\"http://stackoverflow.com/questions/8638665/inapp-purchase-restore-transactions-i-am-not-able-to-figure-the-$c$c-out\">this.但没有得到该产品是用于购买用户，哪些不是。

I have seen this SO Question:this, and this. But not getting which product is purchase for that user and which not.

先谢谢了。
