Android Studio - 应用内购买：billingclient 问题-解网

问：

几年前，我为Android制作了一个应用程序，但该项目被错误地删除了。又过了几年，我决定再写一遍。所以我来到了我想添加应用购买（删除广告）的部分，但不知何故它没有按计划工作。我尝试过按照文档并在线搜索，但没有运气。

我在我的应用程序build.gradle中有这些：

dependencies {

    implementation("androidx.appcompat:appcompat:1.6.1")
    implementation("com.google.android.material:material:1.10.0")
    implementation("androidx.constraintlayout:constraintlayout:2.1.4")
    implementation("androidx.test.espresso:espresso-core:3.5.1")

    val billing_version = "6.1.0"

    implementation("com.android.billingclient:billing:$billing_version")
    implementation("com.android.billingclient:billing-ktx:$billing_version")

    testImplementation("junit:junit:4.13.2")
    androidTestImplementation("androidx.test.ext:junit:1.1.5")
    androidTestImplementation("androidx.test.espresso:espresso-core:3.5.1")
}

这是我的 Java 类的样子：

            BillingFlowParams billingFlowParams = BillingFlowParams.newBuilder()
                    .setSkuDetails(myProductSkuDetails)
                    .build();

            // Launch the billing flow
            BillingResult result = billingClient.launchBillingFlow(this, billingFlowParams);
            if (result.getResponseCode() != BillingClient.BillingResponseCode.OK) {
                // Handle the error


            }
        } else {
            // SkuDetails not available, handle accordingly

            Toast.makeText(this, "SkuDetails not available", Toast.LENGTH_SHORT).show();
        }
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        if (billingClient != null) {
            billingClient.endConnection();
        }
    }
}

问题：

因此，当我加载此活动时，它打开正常，没有错误，也没有 Toast 消息。但是当我按下时，它会给我 Toast 消息：.onUpgradeButtonClickSkuDetails not available

我在支持 Google Play 商店的模拟器 Pixel 7 API 34 上运行它，并且我已登录到 Google Play 商店。

有什么建议吗？

代码更新如下：

所以我尝试了一种不同的方法。我一直在关注YouTube视频。为了进行测试，现在实际显示应用内购买名称，但按 .启动或按下时不会显示 Toast，文本也不会显示任何内容。这是我得到的：upgradeButtonupgradeButtoniapTextView

根据官方的 google-in-app-billing 文档，您应该，

替换为SkuDetailsParamsQueryProductDetailsParams
切换通话以使用BillingClient.querySkuDetailsAsync()BillingClient.queryProductDetailsAsync()

更新功能querySkuDetails()

 private void querySkuDetails() {
    // QueryProductDetailsParams for your product
    QueryProductDetailsParams.Product inAppProduct = QueryProductDetailsParams.Product.newBuilder()
            .setProductId("com.xxxxxxx.yyyyyyyyyyyyy.pro")
            .setProductType(BillingClient.ProductType.INAPP)
            .build();
    List<QueryProductDetailsParams.Product> productList = Arrays.asList(inAppProduct);
    QueryProductDetailsParams params = QueryProductDetailsParams.newBuilder()
            .setProductList(productList)
            .build();
    billingClient.queryProductDetailsAsync(params, (billingResult, productDetailsList) -> {
        // productDetailsList will be List<ProductDetails>
        if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK && !productDetailsList.isEmpty()) {
            // Use the first productDetailsList object
            Toast.makeText(this, "Billing OK", Toast.LENGTH_SHORT).show();
            myProductSkuDetails = productDetailsList.get(0);
        } else {
            Toast.makeText(this, "Failed to retrieve SKU details", Toast.LENGTH_SHORT).show();
        }
    });
}

更新后，您的对象将更改为queryProductDetailsAsyncmyProductSkuDetailsProductDetails

 private ProductDetails myProductSkuDetails; // Define SkuDetails field

有关详细信息，请参阅 integrate-google-in-app-billing 和 Migration-to-goggle-play-billing-v6 官方文档。

不知何故，它仍然给了我信息。SkuDetails not available

@Saland，你确定你得到了回应吗？请首先验证您获得的产品详细信息。queryProductDetailsAsyncproductDetailsListqueryProductDetailsAsync

如果我这样做：，Toast 消息永远不会出现。

if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) {                     // The billing client is ready, query SkuDetails here                     Toast.makeText(InfoController.this, "Ready", Toast.LENGTH_SHORT).show();                     querySkuDetails();                 }

@Saland，似乎您的函数没有被调用，您必须显示 toast“计费设置失败：”对吗？它显示了什么错误？querySkuDetails()

0赞 Harshali 11/18/2023

@Saland，首先验证您在初始化或连接中可能发出的响应。onBillingSetupFinished()startConnectionBillingClient
