java - 如何多次购买 Google Play 产品？

Question

我只能购买一件商品(“productitem1”)。如果我购买了该商品，我将无法再次购买。但我需要它来多次购买。在我的 Google Play 控制台中，我只能在“托管应用内产品”和“订阅”之间进行选择。我已将其设置为“托管应用内产品”。

@Override
protected void onActivityResult(int request, int response, Intent data) {
    if (request == 42) {
        int responseCode = data.getIntExtra("RESPONSE_CODE", 0);
        String purchaseData = data.getStringExtra("INAPP_PURCHASE_DATA");
        String dataSignature = data.getStringExtra("INAPP_DATE_SIGNATURE");
        if (response == RESULT_OK) {
            try {
                JSONObject jo = new JSONObject(purchaseData);
                String productId = jo.getString("productId");
                Toast.makeText(this, "OK", Toast.LENGTH_SHORT).show();
            } catch (JSONException e) {
                Log.e(getClass().getSimpleName(), "JSONException", e);
            }
        }
    }
}

btnBuy.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            final String name = "productitem1";
            try {
                Bundle buyIntentBundle = mService.getBuyIntent(3, getPackageName(), name, "inapp", "");
                if(buyIntentBundle.getInt("RESPONSE_CODE")==0) {
                    PendingIntent pendingIntent = buyIntentBundle.getParcelable("BUY_INTENT");
                    startIntentSenderForResult(
                            pendingIntent.getIntentSender(), 42, new Intent(), Integer.valueOf(0), Integer.valueOf(0), Integer.valueOf(0));
                }
            } catch (Exception e) {
                Log.e(Start.this.getClass().getSimpleName(),"Exception:",e);
            }

        }
    });

在购买具有相同 SKU 的另一件商品之前，您需要使用 In-App Billing API 提供的方法之一消费它，例如 IabHelper.consumeAsync()

mHelper.consumeAsync(inventory.getPurchase(SKU_ITEM), mConsumeFinishedListener);

IabHelper.OnConsumeFinishedListener mConsumeFinishedListener =
           new IabHelper.OnConsumeFinishedListener() {
    public void onConsumeFinished(Purchase purchase, IabResult result) {
        if (result.isSuccess()) {
            // provision the in-app purchase to the user
            // (for example, credit 50 gold coins to player's character)
        } else {
            // handle error
        }
    }
};
