Describe the bug

When I'm doing a release build of my App that uses Amplify UI I get the following:

> Task :app:minifyReleaseWithR8 AGPBI: {"kind":"warning","text":"Missing class kotlinx.parcelize.Parcelize (referenced from: com.amplifyframework.notifications.pushnotifications.NotificationContentProvider$FCM and 2 other contexts)","sources":[{}],"tool":"R8"}

I can get around this by including the following in my proguardrules.pro
-dontwarn kotlinx.parcelize.Parcelize*

But the needed rules should really come with the library

This appears to be coming from the underlying Amplify library, not from Authenticator. Authenticator does not use push notifications. Transferring the issue there.

Hi @pmellaaho, I've looked at this report and have been unable to reproduce this issue. In my sample app, I have the following Amplify dependencies:

    val amplify = "2.17.0"
    implementation("com.amplifyframework:core:$amplify")
    implementation("com.amplifyframework:aws-api:$amplify")
    implementation("com.amplifyframework:aws-datastore:$amplify")
    implementation("com.amplifyframework:aws-auth-cognito:$amplify")
    implementation("com.amplifyframework:aws-push-notifications-pinpoint:$amplify")

I have minify enabled and have the default empty proguard rules:

debug {
    isMinifyEnabled = true
    proguardFiles(
        getDefaultProguardFile("proguard-android-optimize.txt"),
        "proguard-rules.pro"
    )
}

Yet I'm able to build and minify without issue. Can you provide any more details that would suggest the library is at fault?

Hello, thanks for looking into this.
I have the following dependencies:

authenticator = { module = "com.amplifyframework.ui:authenticator", version.ref = "authenticatorVersion" } aws-auth-cognito = { module = "com.amplifyframework:aws-auth-cognito", version.ref = "awsAuthCognitoVersion" } core-kotlin = { module = "com.amplifyframework:core-kotlin", version.ref = "coreKotlinVersion" }

I'm not sure which changes in my code has made the build warning to go away but I'm not seeing it anymore either. I have to return to this subject if the problem appears later again.
