如何在Google Play计费中获取关于Android应用内购买的信息

Question

我希望获取有关如何在Android Studio中使用互联网连接或无互联网连接获取已购买产品的详细信息的信息。

据我所知，Google Play结算库有两种检索信息的方法。

1. PurchasesResult purchasesResult = billingClient.queryPurchases(SkuType.INAPP);

2. 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.
            }
         }
    }
});

但是我不知道如何检索这些信息。

This is the way I have implemented In-App Purchase. It is working smoothly. Hope it helps.

mBillingClient = BillingClient.newBuilder(this).setListener(new PurchasesUpdatedListener() {
            @Override
            public void onPurchasesUpdated(int responseCode, @Nullable List<Purchase> purchases) {

                //  Log.d("anupam", responseCode + "");
                if (responseCode == BillingClient.BillingResponse.OK && purchases != null) {
                    for (Purchase purchase : purchases) {
                    //List of purchases
                    }
                } else if (responseCode == BillingClient.BillingResponse.USER_CANCELED) {
                    Toast.makeText(SplashActivity.this, "Sorry, you have canceled purchase Subscription.", Toast.LENGTH_SHORT).show();
                } else {
                    Toast.makeText(SplashActivity.this, "Sorry, some error occurred.", Toast.LENGTH_SHORT).show();
                }
            }
        }).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.

                    final Purchase.PurchasesResult purchasesResult = mBillingClient.queryPurchases(BillingClient.SkuType.SUBS);
                    for (Purchase sourcePurchase : purchasesResult.getPurchasesList()) {
                        if (sourcePurchase != null) {

                            ConsumeResponseListener listener = new ConsumeResponseListener() {
                                @Override
                                public void onConsumeResponse(final int responseCode, final String purchaseToken) {
                                    // Log.d("anupam2", responseCode + "  <------->  "+ purchasesResult.getPurchasesList() + "  <------->  " + purchaseToken);
                                }
                            };
                            mBillingClient.consumeAsync(sourcePurchase.getPurchaseToken(), listener);
                        } else {

                        }
                    }

                    if (purchasesResult.getPurchasesList().size() > 0) {
                        //  Log.d("anupam3", purchasesResult.getPurchasesList().size() + "");

                    } else {
                        //  Log.d("anupam4", purchasesResult.getPurchasesList().size() + "");
                        BillingFlowParams.Builder builder = BillingFlowParams.newBuilder().setSku("234r23446").setType(BillingClient.SkuType.SUBS);
                        int responseCode = mBillingClient.launchBillingFlow(SplashActivity.this, builder.build());
                        if (responseCode == 7) {

                            //Item already purchased
                        }
                    }
                }
            }

            @Override
            public void onBillingServiceDisconnected() {
                // Try to restart the connection on the next request to
                // Google Play by calling the startConnection() method.
                Toast.makeText(SplashActivity.this, "Failed", Toast.LENGTH_LONG).show();
            }
        });
