BillingFlowParams.Builder setSkuDetails for testing static Google Play Billing responses

Question

I'm testing in-app purchase using the three reserved product IDs for testing static Google Play Billing responses:

• android.test.purchased
• android.test.canceled
• android.test.item_unavailable

However, setSku and setType seem to be deprecated in the BillingFlowParams.Builder class. Instead, we should be using setSkuDetails(SkuDetails).

How should I change the BillingFlowParams in the example code to use SkuDetails for the test product IDs?

BillingFlowParams flowParams = BillingFlowParams.newBuilder()      .setSku(skuId)      .setType(SkuType.INAPP)       .build(); int responseCode = mBillingClient.launchBillingFlow(flowParams); 

Answer 1

you should get SkuDetails from BillingClient.querySkuDetailsAsync, the sample code may seems like this:

private BillingClient mBillingClient;  // ....  mBillingClient = BillingClient.newBuilder(this).setListener(new PurchasesUpdatedListener() {     @Override     public void onPurchasesUpdated(int responseCode, @Nullable List<Purchase> purchases) {         if (responseCode == BillingClient.BillingResponse.OK                 && purchases != null) {              // do something you want          } else if (responseCode == BillingClient.BillingResponse.USER_CANCELED) {         } else {         }     } }).build();   mBillingClient.startConnection(new BillingClientStateListener() {     @Override     public void onBillingSetupFinished(@BillingClient.BillingResponse int billingResponseCode) {          if (billingResponseCode == BillingClient.BillingResponse.OK) {         // The billing client is ready. You can query purchases here.  List<String> skuList = new ArrayList<>();         skuList.add("android.test.purchased");  SkuDetailsParams skuDetailsParams = SkuDetailsParams.newBuilder()                     .setSkusList(skuList).setType(BillingClient.SkuType.INAPP).build(); mBillingClient.querySkuDetailsAsync(skuDetailsParams,                     new SkuDetailsResponseListener() {  @Override   public void onSkuDetailsResponse(int responseCode, List<SkuDetails> skuDetailsList) {    BillingFlowParams flowParams = BillingFlowParams.newBuilder()                                     .setSkuDetails(skuDetailsList.get(0))                                     .build();   int billingResponseCode = billingClient.launchBillingFlow(SkuActivity.this, flowParams);   if (billingResponseCode == BillingClient.BillingResponse.OK) {                                 // do something you want                             }                         }                     });                  }                }   @Override     public void onBillingServiceDisconnected() {         // Try to restart the connection on the next request to         // Google Play by calling the startConnection() method.     } });

I'm posting a step by step process for in-app billing, which I had tested recently after the release of Billing Library version 4.0

Google help resource can be found here

First things first: Update your build.gradle

dependencies {     def billing_version = "4.0.0"      implementation "com.android.billingclient:billing:$billing_version" } 

Now, comes the coding part: BillingActivity.java

private BillingClient mBillingClient;  // ...   submitButton.setOnClickListener(v -> {     mBillingClient = BillingClient.newBuilder(this).enablePendingPurchases().setListener(new PurchasesUpdatedListener() {         @Override         public void onPurchasesUpdated(BillingResult billingResult, List<Purchase> purchases) {             if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK                     && purchases != null) {                 for (Purchase purchase : purchases) {                     handlePurchase(purchase);                 }                 // Perform your Successful Purchase Task here                                   Snackbar.make(findViewById(android.R.id.content), "Great!! Purchase Flow Successful! :)", Snackbar.LENGTH_LONG).show();                 dismiss();             } else if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.USER_CANCELED) {                 // Handle an error caused by a user cancelling the purchase flow.                 Snackbar.make(findViewById(android.R.id.content), "User Cancelled the Purchase Flow!", Snackbar.LENGTH_LONG).show();             } else {                 // Handle any other error codes.                 Snackbar.make(findViewById(android.R.id.content), "Error! Purchase Task was not performed!", Snackbar.LENGTH_LONG).show();             }         }     }).build();      mBillingClient.startConnection(new BillingClientStateListener() {          @Override         public void onBillingSetupFinished(@NonNull BillingResult billingResult) {              if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) {                 // The BillingClient is ready. You can query purchases here.                  List<String> skuList = new ArrayList<>();                 skuList.add("billing_template_1");                 skuList.add("billing_template_2");                 SkuDetailsParams.Builder params = SkuDetailsParams.newBuilder();                 params.setSkusList(skuList).setType(BillingClient.SkuType.INAPP);                 mBillingClient.querySkuDetailsAsync(params.build(),                         new SkuDetailsResponseListener() {                             @Override                             public void onSkuDetailsResponse(BillingResult billingResult,                                                              List<SkuDetails> skuDetailsList) {                                 // Process the result.                                 // Retrieve a value for "skuDetails" by calling querySkuDetailsAsync().                                 BillingFlowParams billingFlowParams = BillingFlowParams.newBuilder()                                         .setSkuDetails(skuDetailsList.get(0))                                         .build();                                 int responseCode = mBillingClient.launchBillingFlow(activity, billingFlowParams).getResponseCode();                             }                         });             }         }          @Override         public void onBillingServiceDisconnected() {             // Try to restart the connection on the next request to Google Play by calling the startConnection() method.             Toast.makeText(BillingActivity.this, "Service Disconnected!", Toast.LENGTH_SHORT).show();         }     }); });          void handlePurchase(Purchase purchase) {     ConsumeParams consumeParams =             ConsumeParams.newBuilder()                     .setPurchaseToken(purchase.getPurchaseToken())                     .build();      ConsumeResponseListener listener = new ConsumeResponseListener() {         @Override         public void onConsumeResponse(BillingResult billingResult, @NonNull String purchaseToken) {             if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) {                 // Handle the success of the consume operation.             }         }     };     mBillingClient.consumeAsync(consumeParams, listener); }           private void dismiss() {         Intent intent = new Intent();         intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);         finish();     } 

FYI:

• This is just an updated version to @Renkuei answer posted.
• Don't forget .enablePendingPurchase()
• Don't forget skuList.add("billing_template_1") which has to be done from your Developer Console. So, billing_template_1 is the name of your Monetise > Products > In-app products > Prouduct ID
