2.5 years: 1,000+ hours of writing, 2 full drafts, and over 50,000 words, and that's not even counting the code.

I'm writing a book on Android screenshot testing, and the first release is coming in April 2026.

Here's what it covers ⬇️

The book dives deep into:

• Why screenshot testing matters for mobile apps
• In-depth comparison of frameworks: Android Testify, Dropshots, Paparazzi, Roborazzi, Shot, and Compose Preview Screenshot Testing
• Practical use of ComposablePreviewScanner and AndroidUiTestingUtils

Plus hands-on examples of screenshot testing a real app:

• Themes
• Localization
• Adaptive UIs
• Font sizes
• CI/CD integration
• Future trends
• AI-assisted screenshot testing

The first release covers 10 chapters, which is 50% of the full book.

The remaining chapters will be shaped by feedback from Android developers, making the final version more practical and impactful.

Early supporters get:
• All future updates at a reduced price
• Help decide which topics get covered in the remaining chapters
