Integrating Braintree dropin UI into Kotlin Jetpack Compose - kotlin

Question

I'm trying to convert the android/java dropin UI code from here https://developer.paypal.com/braintree/docs/guides/drop-in/setup-and-integration#starting-drop-in into a jetpack compose app. So far I have
#Composable
fun Account(user: FinUser) {
val context = LocalContext.current
val customerToken = user.userData["customerToken"] as String
val dropInRequest = DropInRequest()
.clientToken(customerToken)
val dropInHintLauncher = rememberLauncherForActivityResult(
contract = ActivityResultContracts.StartIntentSenderForResult()
) {
print("pause here")
}
val dropInIntent = dropInRequest.getIntent(context)
val dropInPendingIntent = PendingIntent.getBroadcast(
context, 200, dropInIntent,
PendingIntent.FLAG_UPDATE_CURRENT
)
Column(){
Column(
Modifier
.padding(top = 0.dp)
.clickable { launchDropInUi(
dropInHintLauncher=dropInHintLauncher,
dropInPendingIntent=dropInPendingIntent) }) {
Divider(color = Color.LightGray, thickness = 1.dp)
Row(
modifier = Modifier
.fillMaxWidth()
.padding(20.dp, 10.dp)
) {
Column() {
Text("Payment", color = Color.Gray)
Text("*********9999", color = Color.Black)
}
Spacer(modifier = Modifier.fillMaxWidth())
}
Divider(color = Color.LightGray, thickness = 1.dp)
}
}
}
fun launchDropInUi(dropInHintLauncher: ManagedActivityResultLauncher<IntentSenderRequest, ActivityResult>, dropInPendingIntent: PendingIntent){
dropInHintLauncher.launch(
IntentSenderRequest.Builder(dropInPendingIntent).build()
)
}
When I click on my row there's no dropin UI popup but it does register the click and runs over the launchDropInUi function.

I found the issue. I needed to use
val dropInHintLauncher = rememberLauncherForActivityResult(
contract = ActivityResultContracts.StartActivityForResult()
)
Giving
#Composable
fun Account(user: FinUser) {
val context = LocalContext.current
val customerToken = user.userData["customerToken"] as String
val dropInRequest = DropInRequest()
.clientToken(customerToken)
val dropInHintLauncher = rememberLauncherForActivityResult(
contract = ActivityResultContracts.StartActivityForResult()
){ result: ActivityResult ->
if (result.resultCode == Activity.RESULT_OK) {
// you will get result here in result.data
val data: DropInResult? = result.data?.getParcelableExtra(DropInResult.EXTRA_DROP_IN_RESULT)
}else{
print("throw error popup")
}
}
val dropInIntent = dropInRequest.getIntent(context)
Column(){
Column(
Modifier
.padding(top = 0.dp)
.clickable { launchDropInUi(
dropInHintLauncher =dropInHintLauncher,
dropInIntent =dropInIntent) }) {
Divider(color = Color.LightGray, thickness = 1.dp)
Row(
modifier = Modifier
.fillMaxWidth()
.padding(20.dp, 10.dp)
) {
Column() {
Text("Payment", color = Color.Gray)
Text("*********9999", color = Color.Black)
}
Spacer(modifier = Modifier.fillMaxWidth())
}
Divider(color = Color.LightGray, thickness = 1.dp)
}
}
}
fun launchDropInUi(dropInHintLauncher: ManagedActivityResultLauncher<Intent, ActivityResult>, dropInIntent: Intent){
dropInHintLauncher.launch(dropInIntent)
}
