Get price in-app Billing Library - kotlin

Question

My apk is uploaded in the alpha channel, my products created, the buy button if it works.
I'm trying to show several products to buy in a RecyclerView. The purchases work for me. What I could not do is show the price and title of the products.
In my myadapter.kt file I have the following var var p = ArrayList<String>() and function:
fun queryskudetails() {
billingClient = BillingClient.newBuilder(context).setListener(this).build()
billingClient.startConnection(object : BillingClientStateListener {
override fun onBillingServiceDisconnected() {
Log.i("Disconnected", "billing client")
}
override fun onBillingSetupFinished(responseCode: Int) {
billingClient.let { billingClient ->
val skulist = ArrayList<String>()
skulist.add("books")
skulist.add("pens")
skulist.add("keychains")
val params = SkuDetailsParams.newBuilder()
params.setSkusList(skulist).setType(BillingClient.SkuType.INAPP)
billingClient.querySkuDetailsAsync(params.build(), { responseCode, skuDetailsList ->
if (responseCode == BillingClient.BillingResponse.OK && skuDetailsList != null) {
for (skuDetails in skuDetailsList) {
val sku = skuDetails.sku
val price = skuDetails.price
Log.i("skudetails", sku)
Log.i("skuprice", price)
hashMap[sku] = price
println("===== price and sku ======")
println(price)
println(sku)
println("===== /proce and sku ======")
// add price to array p1 (defined as a global variable)
p1.add(price)
}
p = precios
}
})
}
}
})
}
In the section onBindViewHolder which is where I assign the price and title to a textView:
override fun onBindViewHolder(holder: Vholder, position: Int) {
queryskudetails()
print("-----Here array price print [] -----")
println (p)
var text: String = array[position]
Log.i("text", text)
holder.textView.text = text
holder.Price.text = hashMap[text.toLowerCase()].toString() // this does not work for me, retun null
Log.i("price", hashMap["books"].toString())
println(hashMap[array[position]]) // retunr null
holder.btn.setOnClickListener(View.OnClickListener {
Log.i("button", text.toLowerCase())
var skuid = hashMap2[text]
val flowParams = BillingFlowParams.newBuilder()
.setSku(text.toLowerCase())
.setType(BillingClient.SkuType.INAPP)
.build()
val responseCode = billingClient.launchBillingFlow(context as Activity?, flowParams)
})
}
When I show the price in a textview the following code does not work for me:
holder.Price.text = hashMap[text.toLowerCase()].toString() where Price is var Price: TextView = itemView.findViewById(R.id.price)
As a second option I try to use the matrix p1 where I stored all the prices in thequeryskudetails ()function but it returns empty.
How can I do to use the content of the array p1?

Answer 1

The price is stored in the Map: hashMap, to recover it use the sku (identifier in google play console)
hashMap = {sku1=USD 3.99, sku2=USD 1.99, sku3=USD 3.99}
//to recover the values according to the sku (key)
hashMap[sku1] = USD 3.99
hashMap[sku2] = USD 1.99
As I see in your code holder.Price.text = hashMap[text.toLowerCase()].toString() (in the variable Text you must have the identifier (identifier = sku) in order to recover the price of each product ), it is correct, check that in another part is not making conflict or has repeated.
