blocks|key|201803|text|这就是消耗品和非消耗品之间的区别；非消耗品(您在这里处理的东西)的状态被持续跟踪，而消耗品可以被多次购买。您必须进入您的Play管理控制台并取消/退款销售以再次测试它。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|201804|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

This is the difference between consumable and non-consumable items; non-consumable items (what you seem to be dealing with here) have their state tracked persistently, while consumable items can be purchased multiple times. You'll have to go into your Play management console and cancel/refund the sale to test it again.

blocks|key|3051245|text|事实证明，android.test.purchased项的行为就像一个普通的ID，这意味着如果你想再次购买它，你必须在你的代码中的某个地方消费它。我认为Google文档在这个问题上具有误导性，他们应该添加另一个静态ID，您可以出于测试目的无休止地购买该ID。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3051246|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

It turns out that the android.test.purchased item behaves like a regular ID. It means that if you want be able to buy it again, you have to consume it somewhere in your code. I think that the Google documentation is misleading on this matter, and that they should add another static ID that you can buy endlessly for test purposes.

Add this code to a thread to initiate consume request.

<pre><code>int response = mService.consumePurchase(3, getPackageName(), purchaseToken);
</code></pre>

Here for the purchase test, purchaseToken is

<pre><code>purchaseToken = "inapp:" + getPackageName() + ":android.test.purchased";
</code></pre>

And

<pre><code>if (response == 0)
</code></pre>

then the consumption is successful.

also don't forget to make mService public in 

<blockquote>
 IabHelper.Java
</blockquote>

then it would be possible to access like this:

<pre><code>int response = mHelper.mService.consumePurchase(3, getPackageName(), purchaseToken);

In my case, it appears that Google does not record a purchase for the item. Rather, the local copy of Google Play Services caches the purchase. That way, when a second request is made on the same device, <code>android.test.purchased already owned</code> appears. However, using another device or resetting the device clears the cache, and allows the purchase to be repeated.

In my opinion if your program is not designed to consume the item you do not need to tweak the code in order to clear the memory of an outside vendor. This will make your code more fragile and you will have then to spend a lot of time to add and remove code that does not belong to your software so it is a bad design to implement a solution like that. 

The best solution that worked for me to clear android.test.purchased was 

<pre><code>adb uninstall com.yourapp.name
</code></pre>

and then 

<pre><code>adb shell pm clear com.android.vending
</code></pre>

I did not need to clear cash and to browse my apps setting or to change code for that. I did need to add the adb to path variables of windows system which was pretty straight forward. So yes you need to use adb which you probably need anyway so..

You just add your C:\ ...\android-sdk\platform-tools; in windows path in environment variables, and I imagine that it is pretty simple in mac and linux os as well. Hope it helps someone to spend few days less with implementing android in app billings.

The main issue is you have to consume the <code>android.test.purchased</code> item. But this item won't be available in your query inventory, so you can't consume using the normal flow.

So, if you are using IabHelper, in <code>IabHelper</code> class, you can temporarily change the <code>IInAppBillingService</code> mService to public so that it is accessible from your IabHelper.

Then in your class, you can consume like this,

<pre><code>int response = mHelper.mService.consumePurchase(3, getPackageName(), "inapp:"+getPackageName()+":android.test.purchased");
</code></pre>

If success, the response is going to be 0.

Hope this helps.

If you are in test environment

1) In the case of android.test.purchased, I can reset the fake payment by restarting android device(consumed the inventory).

2) In InApp util there is a file called Security.java make it as following, for temporary. Since the testing payment(fake) always return false due to security exception.

<pre><code>public static boolean verifyPurchase(String base64PublicKey,
 String signedData, String signature) {
 return true; }
</code></pre>

Then in your OnIabPurchaseFinishedListener call fechInvForconsumeItem()

<pre><code>IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener
 = new IabHelper.OnIabPurchaseFinishedListener() {
 public void onIabPurchaseFinished(IabResult result,
 Purchase purchase)
 {
 if (result.isFailure()) {
 // Handle error
 Log.e("123","Failure");

 return;
 }
 else if (purchase.getSku().equals(ITEM_SKU)) {
 Log.e("123","PURCAsed");
 fechInvForconsumeItem(); // Restart device if not consume

 }

 }
 };
</code></pre>

The fechInvForconsumeItem() is

<pre><code> public void fechInvForconsumeItem() {
 mHelper.queryInventoryAsync(mReceivedInventoryListener);
}
IabHelper.QueryInventoryFinishedListener mReceivedInventoryListener
 = new IabHelper.QueryInventoryFinishedListener() {
 public void onQueryInventoryFinished(IabResult result,

 if (result.isFailure()) {
 // Handle failure
 Log.e("11","Failure");



 } else {
 Log.e("11","suc");
 mHelper.consumeAsync(inventory.getPurchase(ITEM_SKU),
 mConsumeFinishedListener);
 }


 }
};
</code></pre>

Consume Listener is

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

 if (result.isSuccess()) {

For testing purposes I also suggest you to insert a piece of code that will be clearing all the products that you've bought before calling a method that initializes gp purchase flow. That is especially comfortable, when you test just one item at the moment. E.g. like this:

<pre><code>PurchasesResult purchasesResult = mBillingClient.queryPurchases(BillingClient.SkuType.INAPP);
 for (Purchase sourcePurchase : purchasesResult.getPurchasesList()) {
 if(sourcePurchase != null){

 ConsumeResponseListener listener = new ConsumeResponseListener() {
 @Override
 public void onConsumeResponse(String outToken, @BillingResponse int responseCode) {

 System.out.println("all consumed");
 }
 };
 mBillingClient.consumeAsync(sourcePurchase.getPurchaseToken(), listener);
 }else{
 System.out.println("null");
 }
 }

// and then initiate whole process with clear "shoping basket"

BillingFlowParams.Builder builder = new BillingFlowParams.Builder()
 .setSku(itemName).setType(BillingClient.SkuType.INAPP);
</code></pre>
