How to acknowledge in-app purchases in android? - android

I have gone through the Play Billing Library
https://developer.android.com/google/play/billing/billing_library_overview
You must acknowledge all purchases within three days. Failure to properly acknowledge purchases results in those purchases being refunded.
The process is doesn't provide any clarity how to acknowledge purchases.
This is what i tried
Is this the correct way to do it.
Thanks in Advance
#Override
public void onPurchasesUpdated(BillingResult billingResult, #Nullable List<Purchase> purchases) {
if(billingResult.getResponseCode()== BillingClient.BillingResponseCode.OK&&purchases!=null){
Toast.makeText(this, "Purchase Successful", Toast.LENGTH_SHORT).show();
for(Purchase purchase:purchases){
handlePurchase(purchase);
}
}else if(billingResult.getResponseCode()== BillingClient.BillingResponseCode.USER_CANCELED){
Toast.makeText(this, "Purchase Cancelled", Toast.LENGTH_SHORT).show();
}else if(billingResult.getResponseCode()== BillingClient.BillingResponseCode.ITEM_ALREADY_OWNED){
Toast.makeText(this, "Already Purchased", Toast.LENGTH_SHORT).show();
} else{
Toast.makeText(this, billingResult.getDebugMessage(), Toast.LENGTH_SHORT).show();
}
//in handlePurchase()
if(!purchase.isAcknowledged())
{
AcknowledgePurchaseParams acknowledgePurchaseParams
= AcknowledgePurchaseParams.newBuilder()
.setPurchaseToken(purchase.getPurchaseToken())
.setDeveloperPayload(purchase.getDeveloperPayload())
.build();
client.acknowledgePurchase(acknowledgePurchaseParams, new AcknowledgePurchaseResponseListener() {
#Override
public void onAcknowledgePurchaseResponse(BillingResult billingResult) {
if(billingResult.getResponseCode()== BillingClient.BillingResponseCode.OK){
Toast.makeText(RemoveAdsActivity.this, "Purchase Acknowledged", Toast.LENGTH_SHORT).show();
}
}
});
}

It mentions acknowledging purchases near half way through that link. There are different ways to acknowledge the purchase depending on the type.
private BillingClient mBillingClient = BillingClient.newBuilder(mActivity).setListener(this).build();
//For non-consumables:
mBillingClient.acknowledgePurchase(acknowledgePurchaseParams, new AcknowledgePurchaseResponseListener());
//For Consumables:
client.consumeAsync(acknowledgePurchaseParams, acknowledgePurchaseResponseListener);
The link I posted includes a sample on how to handle subscriptions.
UPDATE
Here's how to acknowledge both non-consumable and consumable purchases, staring with non-consumable:
First, create the AcknowledgePurchaseParams Class object. For this you need the purchase token which you should be able to get easily as you should be calling this in your onPurchasesUpdated method or another method that you passed purchase to after onPurchasesUpdated:
AcknowledgePurchaseParams acknowledgePurchaseParams =
AcknowledgePurchaseParams.newBuilder()
.setPurchaseToken(purchase.getPurchaseToken())
.build();
Next create your listener that will be used as the second parameter. This will allow you to do something after the purchase is acknowledged. I am displaying a snackbar message in this example (As per worbel's comment you can, and probably should, check the result of this billingResult):
AcknowledgePurchaseResponseListener acknowledgePurchaseResponseListener = new AcknowledgePurchaseResponseListener() {
#Override
public void onAcknowledgePurchaseResponse(BillingResult billingResult) {
getMessage("Purchase acknowledged");
}
};
With these created, use your BillingClient to call the acknowledgePurchase method:
mBillingClient.acknowledgePurchase(acknowledgePurchaseParams, acknowledgePurchaseResponseListener);
The purchase should be successfully acknowledged.
This uses acknowledgePurchase for non-consumable items.
Consumable purchases
This is similar only what they are called is changed - See the explanation for what they are in the above example:
First parameter - Params - set-up:
ConsumeParams consumeParams = ConsumeParams.newBuilder()
.setPurchaseToken(purchase.getPurchaseToken())
.build();
Second parameter - Listener - set-up:
ConsumeResponseListener consumeResponseListener = new ConsumeResponseListener() {
#Override
public void onConsumeResponse(BillingResult billingResult, String purchaseToken) {
getMessage("Purchase acknowledged");
}
}
Now use your BillingClint and consumeAsync:
mBillingClient.consumeAsync(consumeParams, consumeResponseListener);

If you are new and using billing library 4.0.0 then above codes will not work since now all billing process has been put in background thread so make sure you do not call any ui updating code during billing process.
Use:
purchase.getSkus.contains("sku here");
instead of
purchase.getSku.equals("sku here");

Billing client is always reached

I am executing the code described by the google billing library, but my device always connects to the billing client, also if I m in flight mode.
//Initiate billing client
bc = BillingClient.newBuilder(getApplicationContext()).setListener(this).
enablePendingPurchases().build();
bc.startConnection(new BillingClientStateListener() {
#Override
public void onBillingSetupFinished(BillingResult billingResult) {
if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) {
// The BillingClient is ready. You can query purchases here.
Toast.makeText(getApplicationContext(), "Connected", Toast.LENGTH_SHORT).show();
}
}
#Override
public void onBillingServiceDisconnected() {
// Try to restart the connection on the next request to
// Google Play by calling the startConnection() method.
Toast.makeText(getApplicationContext(), "Failure", Toast.LENGTH_SHORT).show();
}
});
Google Play services cache purchases, so it is available offline

Buy same item over and over without consuming - In App purchase android

I have kept a donate tab and want to let the users buy the items over and over again. I have implemented a code but it lets the user buy the specific item only once. I have used managed products in play console for products.
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(billingClient.isReady()){
SkuDetailsParams params=SkuDetailsParams.newBuilder()
.setSkusList(Arrays.asList("purchase_aaa","purchase_bbb","purchase_ccc","purchase_ddd"))
.setType(BillingClient.SkuType.INAPP).build();
billingClient.querySkuDetailsAsync(params, new SkuDetailsResponseListener() {
#Override
public void onSkuDetailsResponse(int responseCode, List<SkuDetails> skuDetailsList) {
if(responseCode==BillingClient.BillingResponse.OK)
{
loadProductToRecyclerView(skuDetailsList);
}
else{
Toast.makeText(Donate.this, "Cannot query product", Toast.LENGTH_SHORT).show();
}
}
});
}
else
{
Toast.makeText(Donate.this, "Not ready", Toast.LENGTH_SHORT).show();
}
}
});
#Override
public void onPurchasesUpdated(int responseCode, #Nullable List<Purchase> purchases) {
if(purchases!=null){
Toast.makeText(this, "Purchased"+purchases.size(), Toast.LENGTH_SHORT).show();
}
}
That's by design and cannot be changed, in-app managed products can only be purchased once.
If you want the user who has paid more to have more features enabled, you will have to create as many in-app managed products as levels exist.
If it is a game in which, for example, the user is consuming items then when he no longer has any, you consume the in-app product so he can buy it again.
Or you can also consume the product immediately after the purchase and keep track of how many he has purchased through your own means, an own server or perhaps through firebase, but this already means that you will have to implement a user authentication system for your app.
Consume a purchase:
ConsumeResponseListener consumeListener = new ConsumeResponseListener() {
#Override
public void onConsumeResponse(BillingResult billingResult, String purchaseToken) {
}
};
String token = purchase.getPurchaseToken();
ConsumeParams consumeParams = ConsumeParams.newBuilder().setPurchaseToken(token).build();
billingClient.consumeAsync(consumeParams, consumeListener);

How to handle Purchase States with Purchase History Record in new Google In App Purchase

I am trying to create a restore purchase system. I want, the user can reach its bought products whichever device he/she logged in. So I use "queryPurchaseHistoryAsync()" method when app launches. My problem starts here.
With new implementation of Google, On contrary to the documentation, queryPurchaseHistoryAsync() parameters changed. Now it takes list of PurchaseHistoryRecord objects as parameter instead of list of Purchase objects.
Android studio can not resolve the method stated in the documentation. With new queryPurchaseHistoryAsync() I couldn't find anyway to check purchases state.( if it is purchased, canceled or pending). That I was able to do with Purchase object with "purchase.getPurchaseState()" method.
Documentation of queryPurchaseHistoryAsync()
billingClient.queryPurchaseHistoryAsync(SkuType.INAPP,
new PurchaseHistoryResponseListener() {
#Override
public void onPurchaseHistoryResponse(BillingResult billingResult,
List<Purchase> purchasesList) {
if (billingResult.getResponseCode() == BillingResponse.OK
&& purchasesList != null) {
for (Purchase purchase : purchasesList) {
// Process the result.
}
}
}
});
My implementation
implementation 'com.android.billingclient:billing:2.0.3'
queryPurchaseHistoryAsync() Method in my app
billingClient.queryPurchaseHistoryAsync(BillingClient.SkuType.INAPP,
new PurchaseHistoryResponseListener() {
#Override
public void onPurchaseHistoryResponse(BillingResult billingResult, List<PurchaseHistoryRecord> purchaseHistoryRecordList) {
if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK
&& purchaseHistoryRecordList != null) {
for (PurchaseHistoryRecord purchaseHistoryRecord : purchaseHistoryRecordList) {
HandleOldGetting(purchaseHistoryRecord.getSku());
}
}
}
Release Note of Google(05-2019):
"To minimize confusion, queryPurchaseHistoryAsync() now returns a
PurchaseHistoryRecord object instead of a Purchase object. The PurchaseHistoryRecord object is the same as a Purchase object, except that it reflects only the values returned by queryPurchaseHistoryAsync() and does not contain the autoRenewing, orderId, and packageName fields. Note that nothing has changed with the returned data—queryPurchaseHistoryAsync() returns the same data as before."
But neither release note nor documentation state how to check Purchase State with PurchaseHistoryRecord.
Thank you for reading this, any help is appreciated.
So far, I have been using queryPurchases() to restore purchase automatically as it does not require any networking.
Google play app's cache related to account is updating for all devices. In many cases you won't need call to queryPurchaseHistoryAsync call for restoration.
As stated in #bospehre comment. It has drawback as it depends on the cache. So we still need to check purchases situations and restore them with network call.
For queryPurchaseHistory Async call, we can get the purchase sku and token. If you are using server to hold subscription datas as Google recommends. You can check this subscription's situations via your server.
Here is an example for restoring the latest subscription of the user.
billingManager.billingClient.queryPurchaseHistoryAsync(BillingClient.SkuType.SUBS) { billingResult, purchaseHistoryRecords ->
if (purchaseHistoryRecords != null) {
var activePurchaseRecord : PurchaseHistoryRecord? = null
if (purchaseHistoryRecords.size > 0) {
// Get the latest subscription. It may differ for developer needs.
for (purchaseHistoryRecord in purchaseHistoryRecords) {
Log.d(billingLogs, "Purchase History Record : $purchaseHistoryRecord")
if (billingResult.responseCode == BillingClient.BillingResponseCode.OK) {
if (subSkuListHelper.getSkuList().contains(purchaseHistoryRecord.sku)
) {
if (activePurchaseRecord == null) {
activePurchaseRecord = purchaseHistoryRecord
} else {
if (purchaseHistoryRecord.purchaseTime > activePurchaseRecord.purchaseTime) {
activePurchaseRecord = purchaseHistoryRecord
}
}
}
}
}
Toast.makeText(
this,
"Subscription Purchases found, Checking validity...",
Toast.LENGTH_SHORT
).show()
// Make a network call with sku and purchaseToken to get subscription info
//Subscription Data Fetch is a class that handling the networking
activePurchaseRecord?.let { SubscriptionDataFetch(
this,
billingManager.billingClient
)
.executeNetWorkCall(
getString(R.string.ubscription_check_endpoint),
it.sku,
it.purchaseToken
)
}
}
else {
Log.d(billingLogs, "Purchase History Record not found size 0") }
}
else {
Toast.makeText(
this,
"Purchase not found",
Toast.LENGTH_SHORT
).show()
Log.d(billingLogs, "Purchase History Record not found null")
}
}

How do I check purchase history after delete and reinstall application

I am developing an application which will allow user to purchase using In App Purchase and I want to remove ads after purchase. I can purchase succesfully with code below
BillingFlowParams flowParams = BillingFlowParams.newBuilder()
.setSku("android.test.purchased")
.setType(BillingClient.SkuType.INAPP)
.build();
mBillingClient.launchBillingFlow(getActivity(), flowParams);
But I cannot see the result from queryPurchaseHistoryAsync when I open app again and call this method below.
mBillingClient.queryPurchaseHistoryAsync(BillingClient.SkuType.INAPP, new PurchaseHistoryResponseListener() {
#Override
public void onPurchaseHistoryResponse(int responseCode, List<Purchase> purchasesList) {
purchasesList.size();
}
});
purchasesList.size() == 0
Is "queryPurchaseHistoryAsync" method cannot show test purchase or Am I doing something wrong?
Edit: Is queryPurchaseHistoryAsync method check purchase after delete and install app again.
Yes queryPurchaseHistoryAsync method check purchase after deleting and installing the app again against particular user
mBillingClient.queryPurchaseHistoryAsync(BillingClient.SkuType.INAPP, new PurchaseHistoryResponseListener() {
#Override
public void onPurchaseHistoryResponse(#NonNull BillingResult billingResult, #Nullable List<PurchaseHistoryRecord> list) {
}
});
Try this it will give all purchase items.
mBillingClient.querySkuDetailsAsync(params.build(),
new SkuDetailsResponseListener() {
#Override
public void onSkuDetailsResponse(int responseCode, List<SkuDetails> skuDetailsList) {
listener.onSkuDetailsResponse(responseCode, skuDetailsList);
}
});
mBillingClient.queryPurchases() is all you need. Call it at every app start and, for example, every time your main activity resumes. This way your (reinstalled) app will eventually detect all user's purchases.

How to check the expiration for subscription items

QueryInventoryFinishedListener of IabHelper has not returned the expired subscription items.
On the other hand, PurchaseHistoryResponseListener of Google Play Billing Library seems to receive all purchased items, which is including expired items.
On Google Play Billing Library, we have to check the purchased date of PurchaseHistoryResponseListener and each expiration date of items?
queryPurchases vs queryPurchaseHistoryAsync
Generally, we should use queryPurchases(String skuType), which does not returns expired items. queryPurchaseHistoryAsync returns enabled and disabled items, as you see the documentation like following.
queryPurchases
Get purchases details for all the items bought within your app. This method uses a cache of Google Play Store app without initiating a network request.
queryPurchaseHistoryAsync
Returns the most recent purchase made by the user for each SKU, even if that purchase is expired, canceled, or consumed.
About queryPurchaseHistoryAsync
I could not image the use case for queryPurchaseHistoryAsync. If we need to use queryPurchaseHistoryAsync, we need the implementation to check if it is expired or not.
private PurchaseHistoryResponseListener listener = new PurchaseHistoryResponseListener() {
#Override
public void onPurchaseHistoryResponse(int responseCode, List<Purchase> purchasesList) {
for (Purchase purchase : purchasesList) {
if (purchase.getSku().equals("sku_id")) {
long purchaseTime = purchase.getPurchaseTime();
// boolean expired = purchaseTime + period < now
}
}
}
};
Purchase object does not have the information of period, so the above period must be acquired from BillingClient.querySkuDetailsAsync or be hard-coded. The following is sample implementation to use querySkuDetailsAsync.
List<String> skuList = new ArrayList<>();
skuList.add("sku_id");
SkuDetailsParams.Builder params = SkuDetailsParams.newBuilder();
params.setSkusList(skuList).setType(BillingClient.SkuType.SUBS);
billingClient.querySkuDetailsAsync(params.build(), new SkuDetailsResponseListener() {
#Override
public void onSkuDetailsResponse(int responseCode, List<SkuDetails> skuDetailsList) {
if (skuDetailsList == null) {
return;
}
for (SkuDetails skuDetail : skuDetailsList) {
if (skuDetail.getSku().equals("sku_id")) {
String period = skuDetail.getSubscriptionPeriod();
}
}
}
});
