InAppPurchasesComposeLibrary

This is a Library to make in App purchases ans subscriptions integration to Jetpack Compose projects more easier

purchase.mp4

How to use

1. In your root build.gradle add:

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

if you're using kotlin dsl use

repositories {
    ...
    maven { url = uri("https://www.jitpack.io" ) }
}

2. Then include this dependency in your app level build.gradle

dependencies {
	   implementation 'com.github.Felix-Kariuki:InAppPurchasesComposeLibrary:<latest-version>'
}

Implementation

1. Create a new compose project

2. Publish the apk to playstore under closed testing or whichever you prefer

3. On your playstore console on your newly created project under products, select in-app products and create a new product. on Product Id use test_product then on product details add a product name and description and choose your prefered subscription amount. Once done remember to activate the subscription by clicking activate

4. On your newly created or existing application on android studio,

   • 1. initialize InAppPurchaseHelper class

   and pass the activity and product_id of your in app purchase as you named it on playstore

   val billingPurchaseHelper = InAppPurchasesHelper(this,"test_product")
   billingPurchaseHelper.setUpBillingPurchases()

   NOTE

   • 1.1 For Subscriptions ::

   val billingPurchaseHelper = SubscriptionsHelper(this,"test_product_id")
   billingPurchaseHelper.setUpBillingPurchases()

   if you're implementing it on a compossable screen you can initiliaze it this way

   val billingPurchaseHelper = InAppPurchasesHelper(LocalContext.current,"test_product_id")
   billingPurchaseHelper.setUpBillingPurchases()

   for subscriptions

   val billingPurchaseHelper = SubscriptionsHelper(LocalContext.current,"test_product_id")
   billingPurchaseHelper.setUpBillingPurchases()

   you can also collect the purchse process, prduct name and purchase status by implementing this:

   val purchaseDone by billingPurchaseHelper.purchaseDone.collectAsState(false)
   val productName by billingPurchaseHelper.productName.collectAsState("")
   val purchaseStatus by billingPurchaseHelper.purchaseStatus.collectAsState("")

   • 2. on our purchases button on onClick initializePurchase

   billingPurchaseHelper.initializePurchase()

   if it's a one time purchase you can disable the button by passing purchaseDone as the enabled parameter to disable the button

   Button(
       onClick = {
           billingPurchaseHelper.initializePurchase()
       },
   
       shape = RoundedCornerShape(32.dp),
       colors = ButtonDefaults.buttonColors(
           backgroundColor = MaterialTheme.colors.surface,
           contentColor = MaterialTheme.colors.onSurface
       ),
       modifier = Modifier.wrapContentSize(),
       enabled = purchaseDone
   ) {
       Icon(
           Icons.Filled.More,
           contentDescription = "InApp Purchases",
           modifier = Modifier.size(ButtonDefaults.IconSize)
       )
       Spacer(Modifier.size(ButtonDefaults.IconSpacing))
       Text(
           "In App Purchases",
           fontSize = 16.sp,
           modifier = Modifier.padding(8.dp)
       )
   }
