Android In-App Billing V5 subscription with trial period

Google has updated its billing system and there is no full information how to deal with it.

Thus, instead of SkyDetails we have class ProductDetails. This object we can receive in callback of billingClient.queryProductDetailsAsync(). Then we can call getSubscriptionOfferDetails() on this object and get access to list of ProductDetails.PricingPhases. For example, if product has 2 offers(base and trial offer) we get list of 2 ProductDetails.PricingPhases.

Then when user want to buy a product we use this(from official doc):

val offerToken = productDetails.offerDetails(selectedOfferIndex).offerToken

What is selectedOfferIndex ? Should we always select first item or it depends?

Thanks everyone in advance.

The selectedOfferIndex depends on the offer the developer want to give to the users.

We have to loop through the total offers(getSubscriptionOfferDetails()) and use the token for the offer we want to give.

ProductDetails productDetails;
String offerToken = "";
        if (productDetails.getSubscriptionOfferDetails() != null) {
            for(int i = 0; i < productDetails.getSubscriptionOfferDetails().size();i++) {
                offerToken =  productDetails.getSubscriptionOfferDetails().get(i).getOfferToken();
                if(!offerToken.isEmpty()){
                    break;
                }
            }
        }

if there is only base plan then only one token is returned.

if there is base plan and free tril offer then getSubscriptionOfferDetails().size() will return 2

With Base + trial, when I pass 0th index token enter image description here

With Base + trial, when I pass 1st index token enter image description here

Example you have 2 subscriptions (2 products) like this

[
  ProductDetails{
    parsedJson={
      "productId": "...",
      "subscriptionOfferDetails": [
        {
          "offerIdToken": "...token_1...",
          "pricingPhases": [
            {
              "priceAmountMicros": 631000000000,
              "priceCurrencyCode": "VND",
              "formattedPrice": "₫631,000",
              "billingPeriod": "P6M",
              
            }
          ]
        }
      ]
    }
  },
  ProductDetails{
    parsedJson={
      "productId": "...",
      "subscriptionOfferDetails": [
        {
          "offerIdToken": "...token_2...",
          "pricingPhases": [
            {
              "priceAmountMicros": 0,
              "priceCurrencyCode": "VND",
              "formattedPrice": "Free",
              "billingPeriod": "P1M",
              "recurrenceMode": 2,
              "billingCycleCount": 1
            },
            {
              "priceAmountMicros": 112000000000,
              "priceCurrencyCode": "VND",
              "formattedPrice": "₫112,000",
              "billingPeriod": "P6M",
              
            }
          ],
          {
            "offerIdToken": "...token_3...",
            "pricingPhases": [
              {
                "priceAmountMicros": 631000000000,
                "priceCurrencyCode": "VND",
                "formattedPrice": "₫631,000",
                "billingPeriod": "P6M",
              }
            ]
          }
        }
      ]
    }
  }
]

Example to buy the 1st plan (with 1 month free trial) on 2nd subscription (ProductDetails)

val productDetails2 = ...
val offerToken = "...token_2..."
// val offerToken = productDetails2.subscriptionOfferDetails.get(0).offerToken
// in json response, it name is offerIdToken but after parse it's offerToken

val productDetailsParamsList =
    listOf(
        BillingFlowParams.ProductDetailsParams.newBuilder()
            .setProductDetails(productDetails2)
            .setOfferToken(offerToken)
            .build()
    )
val billingFlowParams = BillingFlowParams.newBuilder()
        .setProductDetailsParamsList(productDetailsParamsList)
        .build()

billingClient.launchBillingFlow(this, billingFlowParams)
