title: Android in app purchase consuming error
body: <p>i have almost finished my first app. I have my in-app purchasing working, but it turns out i have a problem with consuming the purchases, since it should be possible to buy the item endless times. I think i have edited the code to consume the purchased item correctly now, I will provide the code so you can correct me if I'm wrong. But even though this code might be correct now, I can't purchase the product on my test device again, since it wasn't consumed when bought in the first place. How can i consume the product now? Here is my updated code.</p>
  
  <pre><code>protected void onActivityResult(int requestCode, int resultCode, Intent data) {
      if (!mHelper.handleActivityResult(requestCode, resultCode, data)) {
          super.onActivityResult(requestCode, resultCode, data);
      }
  }
  
  IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener = new IabHelper.OnIabPurchaseFinishedListener() {
      public void onIabPurchaseFinished(IabResult result, Purchase purchase) {
          if (result.isFailure()) {
              Log.d("Unlock", "Error purchasing: " + result);
              return;
          } else if (purchase.getSku().equals(SKU_HINTS)) {
              consumeItem();              
          }
  
      }
  };
  
  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(SKU_HINTS),
                      mConsumeFinishedListener);
          }
      }
  };
  
  IabHelper.OnConsumeFinishedListener mConsumeFinishedListener = new IabHelper.OnConsumeFinishedListener() {
      public void onConsumeFinished(Purchase purchase, IabResult result) {
  
          if (result.isSuccess()) {
              add_hints();
              purchase1.setText("Purchase complete");
          } else {
              // handle error
          }
      }
  };
  
  public void onClick(View v) {
  case R.id.bUnlockHints:
          mHelper.launchPurchaseFlow(this, SKU_HINTS, 10001,
                  mPurchaseFinishedListener, "");
          break;
   }
