How to consume product inapp billing to purchase same product multiple time android

Question

I am unable to purchase same product multiple time, i am not getting where to write the code of consuming product in following code. Can anyone give me any advice?

This is my code:

//-- onCreate

inAppPurchase = new InAppPurchase(this);


//--- calling on button click

inAppPurchase.purchase(this, "android.test.purchased", "123");


//--- class InAppPurchase

public class InAppPurchase {

    public static final String BASE64_ENCODED_PUBLIC_KEY = "XXXXXXXXXXX"; // CONSTRUCT_YOUR_KEY_AND_PLACE_IT_HERE
    public static final int RC_REQUEST = 10001;
    String playStoreProductId;
    IabHelper mHelper;
    Activity activity;

    public InAppPurchase() {
        // TODO Auto-generated constructor stub
    }

    public InAppPurchase(Activity activity) {
        // TODO Auto-generated constructor stub
        mHelper = new IabHelper(activity, BASE64_ENCODED_PUBLIC_KEY);
        mHelper.enableDebugLogging(true);

        // Start setup. This is asynchronous and the specified listener will be called once setup completes.
        Log.d("", "Starting setup.");
        mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() 
        {
            public void onIabSetupFinished(IabResult result) 
            {
                 if (!result.isSuccess()) 
                 {
                     Log.e("", "Problem setting up in-app billing: " + result);
                 }
                 else
                 {
                     Log.e("", "Setup successful. Querying inventory.");     
                 }
            }
        });
    }

    public void purchase(Activity activity, String playStoreProductId, String orderId)
    {
        this.activity = activity;
        this.playStoreProductId = playStoreProductId;
        String payload = orderId;
        mHelper.launchPurchaseFlow(activity, playStoreProductId, RC_REQUEST, mPurchaseFinishedListener, payload);       
    }

    // Callback for when a purchase is finished

                mHelper.queryInventoryAsync(mGotInventoryListener);
            }

Please take a look at this article

To consume a purchase you have to do something like this

public void consumeItem() {
    mHelper.queryInventoryAsync(mReceivedInventoryListener);
}

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

          if (result.isFailure()) {
          // Handle failure
          } else {
                 mHelper.consumeAsync(inventory.getPurchase(ITEM_SKU), 
            mConsumeFinishedListener);
          }
    }
};


IabHelper.OnConsumeFinishedListener mConsumeFinishedListener =
      new IabHelper.OnConsumeFinishedListener() {
       public void onConsumeFinished(Purchase purchase, 
             IabResult result) {

     if (result.isSuccess()) {
          clickButton.setEnabled(true);
     } else {
             // handle error
     }
  }
};

Please take a look at the link i have posted above. It provides step by step instructions. Following them, you will have no problem to consume the purchase.
