我正在尝试使用 IabHelper 实现应用内计费服务。我成功地完成了整个购买过程。

//-----------------------------------------------
public void billingServiceLaunchPurchase(String item) {
//-----------------------------------------------
    if (isNetworkAvailableSync(getBaseContext())) {
        currBuyItem=item;
        billingConsummeType=1;
        mHelper.launchPurchaseFlow(BaseActivity.this, item, 10001, mPurchaseFinishedListener, "");
    }
    else {
        onBillingServiceFailed();  
    }
}

    //-----------------------------------------------
    mPurchaseFinishedListener = new IabHelper.OnIabPurchaseFinishedListener() {
    //-----------------------------------------------
        public void onIabPurchaseFinished(IabResult result, Purchase purchase) 
        {
           if (result.isFailure()) {
              // Handle error
              onBillingServiceFailed();                
              return;
         }      
         else if (purchase.getSku().equals(currBuyItem)) {
             billingServiceConsumeItem();
         }

        }
    }; 

@Override
//-----------------------------------------------------------------------    
protected void onActivityResult(int requestCode, int resultCode, Intent data)
//-----------------------------------------------------------------------
{
    if (billingServiceConnected) {
          if (!mHelper.handleActivityResult(requestCode, resultCode, data)) {     
              super.onActivityResult(requestCode, resultCode, data); …
