[英]Android kotlin google play billing onPurchasesUpdated overrides nothing or is never used
I'm following this docs to implement google pay: 我正在按照以下文档实施Google Pay:
https://developer.android.com/google/play/billing/billing_library_overview https://developer.android.com/google/play/billing/billing_library_overview
After running this function and purchage a product: 运行此功能并购买产品后:
fun buy() {
val skuList = listOf("vip_small")
if (billingClient.isReady) {
val params = SkuDetailsParams
.newBuilder()
.setSkusList(skuList)
.setType(BillingClient.SkuType.INAPP)
.build()
billingClient.querySkuDetailsAsync(params) { responseCode, skuDetailsList ->
if (responseCode == BillingClient.BillingResponse.OK) {
Log.d("lets", "querySkuDetailsAsync, responseCode: $responseCode")
val flowParams = BillingFlowParams.newBuilder()
.setSku("vip_small")
.setType(BillingClient.SkuType.INAPP) // SkuType.SUB for subscription
.build()
val responseCodee = billingClient.launchBillingFlow(this, flowParams)
Log.d("lets", "launchBillingFlow responseCode: $responseCodee")
} else {
Log.d("lets", "Can't querySkuDetailsAsync, responseCode: $responseCode")
}
}
} else {
Log.d("lets", "Billing Client not ready")
}
}
which works fine I want to know if the purchage has been made so I add this code from the cods: 可以正常工作,我想知道是否已购买商品,所以我从鳕鱼中添加了以下代码:
override fun onPurchasesUpdated(@BillingResponse responseCode: Int, purchases: List<Purchase>?) {
if (responseCode == BillingResponse.OK && purchases != null) {
for (purchase in purchases) {
handlePurchase(purchase)
}
} else if (responseCode == BillingResponse.USER_CANCELED) {
// Handle an error caused by a user cancelling the purchase flow.
} else {
// Handle any other error codes.
}
}
But I get the error 'onPurchasesUpdated' overrides nothing
但是我收到错误信息'onPurchasesUpdated' overrides nothing
该错误'onPurchasesUpdated' overrides nothing
So I remove override
and get this "error" 所以我删除了override
并得到了这个“错误”
Function "onPurchasesUpdated" is never used
What the hell?? 我勒个去?? How to call this damn function after the purchage has been made? 购买后如何调用该死的函数?
I got the solution. 我找到了解决方案。
You need to make the activity/fragment use the PurchasesUpdatedListener
like: 您需要使活动/片段使用PurchasesUpdatedListener
例如:
class VIP : AppCompatActivity(), PurchasesUpdatedListener {
}
Then override will work 然后覆盖将起作用
