I making an app in Android Studio using Kotlin. I read about build types here: https://developer.android.com/build/build-variants. That page states:

Android Studio automatically creates the debug and release build types.

Although the debug build type doesn’t appear in the build configuration file, Android Studio configures it with debuggable true.

A build type that doesn’t appear seems hard to configure settings for. I want to set isCrunchPngs = false for both release and debug build types, to improve performance. (I am have already crunched/optimized them all manually, no un-crunched version exists in the project).

However, I can’t tell if isCrunchPngs is actually set to false properly. It doesn’t appear in the Project Structure GUI:

I don’t even know if I am using the release build at all (which is a separate question here: )

• Have I configured the release build properly to not crunch pngs?
• How do I configure the debug build to not crunch pngs, since the debug build doesn’t appear in build.gradle?
• In the buildFeatures{ section, viewBinding and compose are set to true, but for which build type? Just release, just debug, both?

My apologies for the multiple questions, I thought them closely related enough to combine in a single post.

My forever gratitude!

My build.gradle is as follows:

    compileSdk = 34

    defaultConfig {
        applicationId = "com.example.vyze"
        minSdk = 24
        targetSdk = 34
        versionCode = 1
        versionName = "1.0"

        testInstrumentationRunner = "androidx.test.runner.AndroidJUnitRunner"

    }

            )
            isCrunchPngs = false
        }
    }
