Testimonials
"Manifest Android Interview stands as an essential guide for Android developers tackling theory-heavy technical interviews. It seamlessly blends deep technical insights, practical examples, and thoughtful 'Pro Tips for Mastery' sections. The knowledge in this book makes it an invaluable resource for confidently navigating and succeeding in Android interviews."
"Jaewoong (known to many of us in the Android community as skydoves), and his new book 'Manifest Android Interview,' are a must-have for anyone getting ready for an interview, or just wanting to brush up on their Android skills. It's an extensive, detailed, and well-structured resource that contains everything from the basics to the nitty-gritty of the Compose runtime and UI. Being biased, I was especially focused on the Jetpack Compose part and found it to be super helpful, particularly for interview prep. It consistently answers the tough and practical 'whys' and 'hows' to help you learn and improve your problem-solving, in a way that is very similar to content in real interviews. Whether you're new to Compose or getting ready for an interview, this book will certainly boost your Android knowledge and interview confidence."
"Guided by thoughtfully crafted questions, insightful tips, and clear code samples, Manifest Android Interview helps you not only reinforce core Android concepts (e.g. manifest file, lifecycle, intent, service, content providers, broadcast receivers, deep links) but also explore every aspect of building software for Android, from ViewModel to the View system to Jetpack Compose and all in between. No matter your level of expertise, this book offers something for everyone. If you're preparing for your dream role or simply expanding your expertise in the platform we all love, this resource will be an invaluable companion on your journey."
"Manifest Android Interview is perfect for brushing up on fundamentals, preparing for interviews, and revisiting best practices. Its clear structure, searchable format, and thoughtful questions make it a go-to resource for both learning and revisiting core Android concepts."
