Even if the user has refunded, it still recognizes the purchase.

`Inventory() { }

/** Returns the listing details for an in-app product. */
public SkuDetails getSkuDetails(String sku) {
    return mSkuMap.get(sku);
}

/** Returns purchase information for a given product, or null if there is no purchase. */
public Purchase getPurchase(String sku) {
    return mPurchaseMap.get(sku);
}`

The user refunded, but getPurchase returns a non-null value.

I agree with @githubsoooh , Digging into the code v2.0.3, it reads the following:

/** Returns the state of purchase. */
  public @PurchaseState int getPurchaseState() {
    switch (mParsedJson.optInt("purchaseState", PurchaseState.PURCHASED)) {
      case 4:
        return PurchaseState.PENDING;
      default:
        return PurchaseState.PURCHASED;
    }
  }

There is basically no way of handling canceled/refunded purchases…

What if we don’t want to use a backend to check refunds/cancelled purchases?

I found a workaround and wrote the details here: https://issuetracker.google.com/issues/73982566#comment62 Can you folks working on the Billing Library confirm if this is safe or not until you’ll provide a real solution?
