Funsol Billing Helper is a simple, straight-forward implementation of the Android v6.0 In-app billing API
Support both IN-App and Subscriptions.
No extra dependencies required
Add maven repository in project level build.gradle or in latest project setting.gradle file
repositories {
google()
mavenCentral()
maven { url "https://jitpack.io" }
}
Add Funsol Billing Helper dependencies in App level build.gradle.
dependencies {
implementation 'com.github.Funsol-Projects:Funsol-Billing-Helper:v1.0.4'
}
Finally initialise Billing class and setup Subscription Ids
FunSolBillingHelper(this)
.setSubKeys(mutableListOf("Subs Key", "Subs Key 2"))
if both subscription and In-App
FunSolBillingHelper(this)
.setSubKeys(mutableListOf("Subs Key", "Subs Key 2"))
.setInAppKeys(mutableListOf("In-App Key"))
if consumable in-App
FunSolBillingHelper(this)
.setInAppKeys(mutableListOf("In-App Key, In-App consumable Key"))
.setConsumableKeys(mutableListOf("In-App consumable Key"))
Note: you have add consumable key in both func setInAppKeys() and setConsumableKeys()
Call this in first stable activity or in App class
FunSolBillingHelper(this)
.setSubKeys(mutableListOf("Subs Key", "Subs Key 2"))
.setInAppKeys(mutableListOf("In-App Key"))
.enableLogging()
.setBillingClientListener(object : BillingClientListener {
override fun onClientReady() {
Log.i("billing", "onClientReady: ")
}
override fun onClientInitError() {
Log.i("billing", "onClientInitError: ")
}
})
FunSolBillingHelper(this)
.setSubKeys(mutableListOf("Subs Key", "Subs Key 2"))
.setInAppKeys(mutableListOf("In-App Key"))
.enableLogging(isEnableLog = true)
Subscribe to a Subscription
FunSolBillingHelper(this).buyInApp(activity,"In-App Key",false)fasle value used for isPersonalizedOffer attribute:
If your app can be distributed to users in the European Union, use the isPersonalizedOffer value true to disclose to users that an item's price was personalized using automated decision-making.
Note: it auto acknowledge the In-App and give callback when product acknowledged successfully.
Subscribe to a Subscription
FunSolBillingHelper(this).subscribe(activity, "Base Plan ID")Subscribe to a offer
FunSolBillingHelper(this).subscribe(activity, "Base Plan ID","Offer ID")Note: it auto acknowledge the subscription and give callback when product acknowledged successfully.
FunSolBillingHelper(this).upgradeOrDowngradeSubscription(this, "New Base Plan ID", "New Offer Id (If offer )", "Old Base Plan ID", ProrationMode)
ProrationMode is a setting in subscription billing systems that determines how proration is calculated when changes are made to a subscription plan. There are different proration modes, including:
1. DEFERRED
Replacement takes effect when the old plan expires, and the new price will be charged at the same time.
2. IMMEDIATE_AND_CHARGE_FULL_PRICE
Replacement takes effect immediately, and the user is charged full price of new plan and is given a full billing cycle of subscription, plus remaining prorated time from the old plan.
3. IMMEDIATE_AND_CHARGE_PRORATED_PRICE
Replacement takes effect immediately, and the billing cycle remains the same.
4. IMMEDIATE_WITHOUT_PRORATION
Replacement takes effect immediately, and the new price will be charged on next recurrence time.
5. IMMEDIATE_WITH_TIME_PRORATION
Replacement takes effect immediately, and the remaining time will be prorated and credited to the user.
6. UNKNOWN_SUBSCRIPTION_UPGRADE_DOWNGRADE_POLICY
Example :
FunSolBillingHelper(this).upgradeOrDowngradeSubscription(this, "New Base Plan ID", "New Offer Id (If offer )", "Old Base Plan ID", BillingFlowParams.ProrationMode.IMMEDIATE_AND_CHARGE_FULL_PRICE)Interface implementation to handle purchase results and errors.
FunSolBillingHelper(this).setBillingEventListener(object : BillingEventListener {
override fun onProductsPurchased(purchases: List<Purchase?>) {
//call back when purchase occured
}
override fun onPurchaseAcknowledged(purchase: Purchase) {
//call back when purchase occur and acknowledged
}
override fun onPurchaseConsumed(purchase: Purchase) {
//call back when purchase occur and consumed
}
override fun onBillingError(error: ErrorType) {
when (error) {
ErrorType.CLIENT_NOT_READY -> {
}
ErrorType.CLIENT_DISCONNECTED -> {
}
ErrorType.PRODUCT_NOT_EXIST -> {
}
ErrorType.BILLING_ERROR -> {
