如何在Android中延迟订阅(Google Play计费)？

dependencies {
    // 其他依赖项
    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) {
        if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) {
            // 检查订阅权限
            Purchase.PurchasesResult result = billingClient.queryPurchases(BillingClient.SkuType.SUBS);
            if (result.getResponseCode() == BillingClient.BillingResponseCode.OK) {
                List<Purchase> purchases = result.getPurchasesList();
                // 处理已购买的订阅
            }
        }
    }

    @Override
    public void onBillingServiceDisconnected() {
        // 连接断开处理
    }
});
