Android:如何使用Android计费4.0.0恢复之前购买的内容

implementation 'com.android.billingclient:billing:4.0.0'

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

PurchasesUpdatedListener purchasesUpdatedListener = new PurchasesUpdatedListener() {
    @Override
    public void onPurchasesUpdated(BillingResult billingResult, List<Purchase> purchases) {
        if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK && purchases != null) {
            // 处理购买成功的逻辑
        } else if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.USER_CANCELED) {
            // 处理用户取消购买的逻辑
        } else {
            // 处理购买失败的逻辑
        }
    }
};

Purchase.PurchasesResult purchasesResult = billingClient.queryPurchases(BillingClient.SkuType.INAPP);
List<Purchase> purchasesList = purchasesResult.getPurchasesList();

for (Purchase purchase : purchasesList) {
    if (purchase.getSku().equals("your_product_sku")) {
        // 执行恢复购买的逻辑
    }
}
