I'm using this:

@Nullable
public Date getSubscriptionRenewingDate(String sku) {

    // Get the Purchase object:
    Purchase purchase = null;
    Purchase.PurchasesResult purchasesResult = _billingClient.queryPurchases(BillingClient.SkuType.SUBS);
    if (purchasesResult.getPurchasesList() != null) {
        for (Purchase p : purchasesResult.getPurchasesList()) {
            if (p.getSku().equals(sku) && p.getPurchaseState() == Purchase.PurchaseState.PURCHASED && p.isAutoRenewing()) {
                purchase = p;
                break;
            }
        }
    }

    // Get the SkuDetails object:
    SkuDetails skuDetails = null;
    for (SkuDetails s : _skuDetails) { // _skuDetails is an array of SkuDetails retrieved with querySkuDetailsAsync
        if (s.getSku().equals(sku)) {
            skuDetails = s;
            break;
        }
    }

    if (purchase != null && skuDetails != null) {

        Date purchaseDate = new Date(purchase.getPurchaseTime());
        Calendar calendar = Calendar.getInstance();
        calendar.setTime(purchaseDate);

        Date now = new Date();

        while (calendar.getTime().before(now)) {

            switch (skuDetails.getSubscriptionPeriod()) {

                case "P1W": calendar.add(Calendar.HOUR, 7*24); break;
                case "P1M": calendar.add(Calendar.MONTH, 1); break;
                case "P3M": calendar.add(Calendar.MONTH, 3); break;
                case "P6M": calendar.add(Calendar.MONTH, 6); break;
                case "P1Y": calendar.add(Calendar.YEAR, 1); break;
            }
        }

        return calendar.getTime();
    }

    return null;
}
