Check SkuDetails subscription billing frequency

In Android development with Google Billing, how do I get the billing frequency for a Subscription

SkuDetails.subscriptionPeriod() returns a date string. Is there a way to get the billing frequency for example monthly or yearly or am I going to have to just cleverly code this to match what I have in console?

I was wrong to assume truth from searching through other posts. I have debugged and found out that:

SkuDetails.subscriptionPeriod() returns something like P1Y, or P1M, or whatever else as a string.

• P1M: Per 1 Month
• P1Y: Per 1 Year
• etc depending on what subscription frequency you have set up

I am now using those abbreviations for reference.
