Android 16 (16kb Support?)

What happened?

I try to build an APK for Capacitor 8.0, Android 16 and hopefully 16kb Support (not sure if this is relevant).

During build I get the message that using "proguard-android-optimize.txt" should be used instead of "proguard-android.txt" in built.gradle. I actually changed this in the 8.0.0 version of this package but I also had to remove refererences to "proguard_rules.pro" as that file somehow gets deleted during build (?!).

The following parts in build.gradle work but am totally unsure if this is a workable solution?

defaultConfig {
        minSdkVersion project.hasProperty('minSdkVersion') ? rootProject.ext.minSdkVersion : 23
        targetSdkVersion project.hasProperty('targetSdkVersion') ? rootProject.ext.targetSdkVersion : 35
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        // consumerProguardFiles 'proguard-rules.pro'
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt')
        }
    }

BTW, I also added "-optimize" to the build.gradle in "@transistorsoft/capacitor-background-geolocation": "8.0.1" which seems to work without any other change.

I am no Android pro so maybe this a totally wrong but any help is apprecciated, thanks!

Plugin Code and/or Config

not relevant as build process is affected only

"proguard-android-optimize.txt" should be used instead of "proguard-android.txt"

this plugin does not use any of those files.

I guess the problem is the build.gradle file which references the proguard file and Android Studio then complains it is the wrong one. Would it be possible to remove the reference completely from the projects build.gradle?
