Java

UpgradeInfo upgradeInfo = new UpgradeInfo(oldSubsPurchase , prorationMode);

Market.getInstance().purchaseProduct(ProductDetailActivity.this, mProduct, upgradeInfo, new InitiatePurchaseListener() {
    @Override
    public void onVerifying(boolean isVerifying) {
       // Callback of onging verification in the backend
    }

    @Override
    public void onPurchaseSuccess(MTGPurchase purchase) {
       //Purchase success callback
   }

    @Override
    public void onOwnedGoods(MTGPurchase purchase) {

    public void onPurchaseError(int errorCode) {
       //Callback of abnormal purchases
    }
});

Kotlin

    }

    override fun onPurchaseSuccess(purchase: MTGPurchase) {
