如何在Google Play Billing for android中获取应用内购买信息

dependencies {
    implementation 'com.android.billingclient:billing:4.0.0'
}

BillingClient billingClient = BillingClient.newBuilder(context)
    .setListener(purchasesUpdatedListener)
    .enablePendingPurchases()
    .build();

billingClient.startConnection(new BillingClientStateListener() {
    @Override
    public void onBillingSetupFinished(BillingResult billingResult) {
        // 连接成功后的处理逻辑
    }

    @Override
    public void onBillingServiceDisconnected() {
        // 连接断开后的处理逻辑
    }
});

List<String> skuList = new ArrayList<>(); // 商品ID列表
SkuDetailsParams.Builder params = SkuDetailsParams.newBuilder();
params.setSkusList(skuList).setType(BillingClient.SkuType.INAPP); // INAPP表示应用内消耗型商品

billingClient.querySkuDetailsAsync(params.build(), new SkuDetailsResponseListener() {
    @Override
    public void onSkuDetailsResponse(BillingResult billingResult, List<SkuDetails> skuDetailsList) {
        // 获取到商品信息后的处理逻辑
    }
});

BillingFlowParams.Builder builder = BillingFlowParams.newBuilder()
    .setSkuDetails(skuDetails); // skuDetails为之前查询到的商品详细信息

BillingResult billingResult = billingClient.launchBillingFlow(activity, builder.build());

@Override
public void onPurchasesUpdated(BillingResult billingResult, List<Purchase> purchases) {
    if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK && purchases != null) {
        // 购买成功的处理逻辑
    } else {
        // 购买失败的处理逻辑
    }
}
