我正在学习为我的应用实施应用内结算，以便人们可以在按下捐赠按钮时捐出$。
允许用户捐赠多次，即购买是消费品。
以下代码来自TrivalDrive示例和来自网络的一些教程：
IabHelper mHelper;
static final String ITEM_SKU = "android.test.purchased";
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_in_app_billing);
buy10Button = (Button) findViewById(R.id.buy10Button);
buy15Button = (Button) findViewById(R.id.buy15Button);
buy20Button = (Button) findViewById(R.id.buy20Button);
String base64EncodedPublicKey = "keykeykey";
mHelper = new IabHelper(this, base64EncodedPublicKey);
mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener()
{
public void onIabSetupFinished(IabResult result)
{
if (!result.isSuccess())
{
Log.d(TAG, "In-app Billing setup failed: " + result);
return;
}
if (mHelper == null)
{
return;
}
Log.d(TAG, "In-app Billing is set up OK");
}
});
}
public void buy10Click(View view)
{
mHelper.launchPurchaseFlow(this, ITEM_SKU, 10001, mPurchaseFinishedListener, "");
}
public void buy15Click(View view)
{
}
public void buy20Click(View view)
{
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
if (mHelper == null) return;
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 (mHelper == null) return;
if (result.isFailure())
{
// Handle error
return;
}
else if ((purchase.getSku().equals(ITEM_SKU)))
{
consumeItem();
}
}
};
public void consumeItem()
{
mHelper.queryInventoryAsync(mReceivedInventoryListener);
}
IabHelper.QueryInventoryFinishedListener mReceivedInventoryListener = new IabHelper.QueryInventoryFinishedListener()
{
public void onQueryInventoryFinished(IabResult result, Inventory inventory)
{
if (mHelper == null) return;
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 (mHelper == null) return;
if (result.isSuccess())
{
Toast.makeText(InAppBillingActivity.this, "Thank you for your donation!!", Toast.LENGTH_LONG).show();
}
else
{
// handle error
}
}
};
然而，我一直收到E/IabHelper(13392): In-app billing error: Unable to buy item, Error response: 7:Item Already Owned错误，并且Google Play的付款对话框不会弹出。
我已经研究并发现了很多类似的情况，有些建议等待几分钟，然后购买将自行重置，但我已经等了将近一个小时，但它仍然很糟糕。
我还发现有人建议更改IabResult public boolean isSuccess() { return mResponse == IabHelper.BILLING_RESPONSE_RESULT_OK; }以返回BILLING_RESPONSE_RESULT_ITEM_ALREADY_OWNED as isccess = true，但我不知道如何修改...
如何修复问题？谢谢！

您购买了“android.test.purchased”但没有使用它。但是，如果您忘记立即食用，则再次食用它并不容易。我们可以等14天。假购买将自动清除。但这是不可接受的。
我花了很多时间找到解决方案：
添加此行以获取调试信息。
_iabHelper.enableDebugLogging(true, "TAG");
运行该应用。在LogCat中，您将看到类似
的json字符串{"packageName":"com.example","orderId":"transactionId.android.test.purchased","productId":"android.test.purchased","developerPayload":"123","purchaseTime":0,"purchaseState":0,"purchaseToken":"inapp:com.example:android.test.purchased"}
手动使用它（用你的json字符串替换THAT_JSON_STRING）
Purchase purchase;
try {
purchase = new Purchase("inapp", THAT_JSON_STRING, "");
_iabHelper.consumeAsync(purchase, new OnConsumeFinishedListener() {
@Override
public void onConsumeFinished(Purchase purchase, IabResult result) {
Log.d("TAG", "Result: " + result);
}
});
} catch (JSONException e) {
e.printStackTrace();
}
_iabHelper是mHelper。

点击此处查看以下代码：
我在您的代码中不明白为什么您在购买完成侦听器中使用了查询库存。当你获得与你请求的sku相同的sku时，应该调用ConsumeAsync（）方法。
// Callback for when a purchase is finished
IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener = new IabHelper.OnIabPurchaseFinishedListener() {
public void onIabPurchaseFinished(IabResult result, Purchase purchase) {
Log.d(TAG, "Purchase finished: " + result + ", purchase: "
+ purchase);
if (result.isFailure()) {
complain("Error purchasing: " + result);
return;
}
if (!verifyDeveloperPayload(purchase)) {
complain("Error purchasing. Authenticity verification failed.");
return;
}
Log.d(TAG, "Purchase successful.");
if (purchase.getSku().equals(SKU_GAS)) {
// remove query inventory method from here and put consumeAsync() directly
mHelper.consumeAsync(purchase, mConsumeFinishedListener);
}
}
};
startSetup方法
//你忘了在startSetup方法中调用查询库存方法。
mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
public void onIabSetupFinished(IabResult result) {
Log.d(TAG, "Setup finished.");
if (!result.isSuccess()) {
// Oh noes, there was a problem.
complain("Problem setting up in-app billing: " + result);
return;
}
// Hooray, IAB is fully set up. Now, let's get an inventory of
// stuff we own.
Log.d(TAG, "Setup successful. Querying inventory.");
mHelper.queryInventoryAsync(mGotInventoryListener);
}
});
<强> QueryInventoryFinishedListener
并检查条件购买是否与您要求的相同 不等于null，并且查询中的开发人员有效负载也相同 库存完成监听器。
if (gasPurchase != null && verifyDeveloperPayload(gasPurchase)){ //code }
// Listener that's called when we finish querying the items and
// subscriptions we own
IabHelper.QueryInventoryFinishedListener mGotInventoryListener = new IabHelper.QueryInventoryFinishedListener() {
public void onQueryInventoryFinished(IabResult result,
Inventory inventory) {
Log.d(TAG, "Query inventory finished.");
if (result.isFailure()) {
complain("Failed to query inventory: " + result);
return;
}
Log.d(TAG, "Query inventory was successful.");
/*
* Check for items we own. Notice that for each purchase, we check
* the developer payload to see if it's correct! See
* verifyDeveloperPayload().
*/
// // Check for gas delivery -- if we own gas, we should fill up the
// tank immediately
Purchase gasPurchase = inventory.getPurchase(SKU_GAS);
if (gasPurchase != null && verifyDeveloperPayload(gasPurchase)) {
Log.d(TAG, "We have gas. Consuming it.");
mHelper.consumeAsync(inventory.getPurchase(SKU_GAS),
mConsumeFinishedListener);
return;
}
}
};
解释其发生的原因：
每当您购买耗材时，Google Play商店将无法管理其产品购买的详细信息以及Google Play控制台中的其他内容。这就是我们必须调用consumeAsync（）方法的原因。当我们购买商品时，谷歌游戏商店保留记录项目已经购买了一次，并允许您第二次购买。
希望它能解决你的问题。

我设法＆＃34;消费购买＆＃34;只需重新启动设备即可。
答案 3 :(得分：5)
您可以使用Google Play“财务报告” - >“访问您的商家帐户以获取更多详细信息” - ＆gt;“订单”查看和取消任何订单以“消费它”。 然后，您需要重新启动您的设备。 =）

我正在使用：实现'com.android.billingclient：billing：2.0.0'，并且在购买过程中遇到了相同的错误。
请参见下面的代码段：
List<String> skuList = new ArrayList();
skuList.add(THE_IAP_ID);
BillingClient.Builder billingClientBuilder = BillingClient.newBuilder(context).setListener(new PurchasesUpdatedListener() {
@Override
public void onPurchasesUpdated(BillingResult billingResult, @Nullable List<Purchase> purchases) {
// here we have to check the result ...
});
billingClientBuilder.enablePendingPurchases();
billingClient = billingClientBuilder.build();
billingClient.startConnection(new BillingClientStateListener() {
@Override
public void onBillingSetupFinished(BillingResult billingResult) {
if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) {
// The BillingClient is ready - query purchases.
Purchase.PurchasesResult pr = billingClient.queryPurchases(BillingClient.SkuType.INAPP);
List<Purchase> pList = pr.getPurchasesList();
for (Purchase iitem : pList) {
ConsumeParams consumeParams = ConsumeParams.newBuilder()
.setPurchaseToken(iitem.getPurchaseToken())
.build();
billingClient.consumeAsync(consumeParams, consumeResponseListener);
}
// process the purchase
} else {
// cancelled or s.e.
...
}
}
最好的问候，你玩得开心：）
