CODE FORMATTING / PDF EXPORT Updated September 2026

Chapters 3 to 7: PDF Code Copy-Paste Best Practice

If you are viewing or compiling the e-Book in PDF format, line wrapping may occasionally break long Kotlin parameter chains mid-word (e.g. splitting .verticalScroll into vertic / alScroll).

Fix: All source code files in the book repository now utilize multi-line indented parameter formatting. If copying code into Android Studio, ensure line breaks occur after commas or dots (e.g. Modifier.fillMaxWidth() on its own line).

GRADLE BUILD SYSTEM Updated September 2026

Chapter 2: Compile SDK Versioning

In build.gradle.kts, compileSdk and targetSdk are set to version 36 to support modern Android AAR library metadata.

android {
    compileSdk = 36
    defaultConfig {
        targetSdk = 36
    }
}
BILLING LIBRARY v9.x Updated September 2026

Chapter 6: Google Play Billing Initialization

When setting up BillingClient in BillingManager.kt, ensure PendingPurchasesParams explicitly enables one-time products to seamlessly support in-app purchases like ad removal.
