我在应用计费方面遇到一些问题，我想在应用内创建一个可以多次购买的产品。但谷歌以一种产品首先必须消费的方式进行应用程序计费，然后才能再次购买。我用以下代码尝试了它：
public class HomeFragment extends Fragment {
private WebView homesite;
private String homeTabUrl;
private ProgressBar pBar;
private Bundle webViewBundle;
private Boolean buddyProfile = false;
private Boolean buddyProfile2 = false;
String url="";
private Context mContext;
final static String REQUEST_SUCCESS = "COMPLETED";
//Amount point
private static final int CREDIT_AMOUNT_100 = 100;
private static final int CREDIT_AMOUNT_500 = 500;
public static final String PAY_UID_100 = "messages";
public static final String PAY_UID_500 = "messages2";
private int mCreditAmount;
private IabHelper mHelper;
private static final int PAYINAPP_REQUESTCODE = 10001;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
setRetainInstance(true);
StaticMembers.loadHomeTab = true;
purchaseCredit(CREDIT_AMOUNT_100);
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
//Logger.error("YES-HERE IN ONACTIVITY RESULT");
if (checkReultPayInApp(requestCode,resultCode, data)) {
return;
}
if (!mHelper.handleActivityResult(requestCode, resultCode, data)) {
super.onActivityResult(requestCode, resultCode, data);
}
}
@Override
public void onStart() {
super.onStart();
}
private void loadData(View v) {
initPayinApp();
}
private void initPayinApp() {

请告诉我在使用产品时我在做什么错误，以便我可以相应地进行更改。

您应该使用以前购买的物品。
private void initPayinApp() {
// TODO Auto-generated method stub
String base64EncodedPublicKey = "";
mHelper = new IabHelper(getActivity(), base64EncodedPublicKey);
mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
public void onIabSetupFinished(IabResult result) {
if (!result.isSuccess()) {
Log.d("YES", "In-app Billing setup failed: " + result);
} else {
Log.d("YES", "In-app Billing is set up OK");
//comment this function once all the previously purchased items are consumed successfully
reset();
}
}
});
}
void reset() {
mHelper.queryInventoryAsync(mGotInventoryListener);
}
IabHelper.QueryInventoryFinishedListener mGotInventoryListener = new IabHelper.QueryInventoryFinishedListener() {
@Override
public void onQueryInventoryFinished(IabResult result, Inventory inventory) {
Log.d(TAG, "Query inventory finished.");
if (result.isFailure()) {
Log.d(TAG, "Failed to query inventory: " + result);
return;
}
Log.d(TAG, "Query inventory was successful.");
if(inventory.hasPurchase(PAY_UID_100))
{
Log.d(TAG, "already purchased : " + PAY_UID_100);
mHelper.consumeAsync(inventory.getPurchase(PAY_UID_100), mConsumeFinishedListener);
}
if(inventory.hasPurchase(PAY_UID_500))
{
Log.d(TAG, "already purchased : " + PAY_UID_500);
mHelper.consumeAsync(inventory.getPurchase(PAY_UID_500), mConsumeFinishedListener);
}
}
};
