谷歌播放订阅的付款方式？

Question

I am using google play subscription services for my app.But when any use or customer tries to pay for my subscription with any given payment method.It shows -

 Unavailable for this purchase.

Only I can pay with Google play account money.

I tried all method on different mobiles. But problem is same.

I am using standard code given on google developers site.

private BillingClient billingClient=BillingClient.newBuilder(activity)
.setListener(this).build();

billingClient.startConnection(new BillingClientStateListener() {
    @Override
    public void onBillingSetupFinished(BillingResult billingResult) {
        if (billingResult.getResponseCode() == BillingResponse.OK) {
        }
    }
    @Override
    public void onBillingServiceDisconnected() {

    }
});

I want to enable all payment methods for my app.
