Problems with subscription implementation | deprecated codes

Question

let's see if I explain myself correctly, I am trying to implement subscriptions in an application on android studio for the first time, the structure is this:

splash.java -> SubscriptionActivity.java -> MainActivity.java

The user opens the app, shows the splashscreen, then the subscription screen with 5 different plans should appear and after paying the subscription they can access MainActivity.java.

It's my first time doing this and I just see that Google asks that subscriptions be with the new api, I have searched everywhere but I can't do the SubscriptionActivity.java correctly, "is deprecated" appears in several sections and no matter how hard I try To understand the Google guide, I can't update it, I leave you my code and I hope you can please help me.

thank you

in SubscriptionActivity.java it tells me "is deprecated" and I don't know how to fix it, not even by reading the documentation.

The error says it in:

1. private List skuDetailsList;
2. SkuDetailsParams.Builder paramsBuilder = SkuDetailsParams.newBuilder();
3. SkuDetailsParams params = paramsBuilder.build();
4. billingClient.querySkuDetailsAsync(params, new SkuDetailsResponseListener()
5. .setSkuDetails(skuDetailsList.get(index))
