Head First Android Development: A Learner's Guide to Building Android Apps with Kotlin

Was able to work through the whole book without too much difficulty. There are some typos here and there but the author's source code is correct. Had to adjust some gradle files from what Android Studio generated to match the author's source code to compile some apps. Best Android Studio book by far that I have used.

I have quite a few Head Start books. They are so much fun to learn from. And this one particularly is of tremendous help. So far all the examples compile well. Thanks.

Good grief, you put in the code changes it says to make in the Gradle scripts and the whole thing blows up with error messages. not to mention the quality of book itself just totally sucks. had it for 3 days and pages are starting to come out. O'Reilly, has really gone down hill. Just say no to this book.

Sadly, the authors teach outdated programming concepts. If you are new to android app development, don't get this book. Find jetpack compose material instead. Layouts are out. XML UI is gone. FindByID...adios. Do learn about higher-order functions and lambdas ASAP. Composables (the new UI) use them ALOT. Because I'm already on the negative path...the images of 1940s women in bathing suits and standing behind their men are disturbingly sexist. Especially with a female author. And the woman making angry, snarky comments didn't appeal to me either.

Head first books are garbage. This book is more than 800 pages but at least 50% of it is totally useless garbage. In fact, the one thing I actually needed it for doesn't even mention it: PeriodicWorkRequest. There is exactly 1 page on WorkManager and just like the rest of the book there is a bunch of totally useless copy and a link to the API docs. Thanks, if I wanted to look in the API docs I wouldn't have gotten this book. I guarantee you this book will actually hinder learning Android development rather than help.

Great book, but I've found a few typos that will drive the newbie bonkers. If your code doesn't seem to work, ensure the syntax is correct. The book is mostly correct but don't blindly trust it. For example, on page 109 there is an extra " before xmlns.

Ho già l'altro testo Head First Kotlin e questo è la sua attuale evoluzione. Sono partito con un nanodegree Udacity, mi è venuto mal di testa per il materiale datato che viene fatto pagare a peso d'oro, ho chiesto il rimborso e acquistato la versione cartacea di questo manuale. Più che soddisfatto.

A linguagem é bem leve, fácil de acompanhar. O desenvolvimento dos mini-projetos é bem detalhado e cumulativo com os desenvolvimentos anteriores. A versão não é a mais atual, mas não prejudica (em 2 ou 3 mini-projetos eu tive que adaptar as alterações a serem feitas no build.gradle). Para quem não conhece nada de Android (mas já sabe programar... talvez até pra quem não sabe programar) é um excelente guia. Os principais assuntos cobertos são desenvolvimento de interfaces. E tem também um mini-projeto com banco de dados local (excelente por sinal). Não entra em questões mais profundas (o que é uma atividade? quando uma aplicação tem mais de uma atividade?). No último capítulo, embora não ensine, dá ótimos ponteiros para outras features da plataforma (notificações por exemplo). Eu agora vou procurar livros mais profundos e algum guia que ensine a fazer UX efetivas (não do ponto de vista técnico na programação, mas com foco em usabilidade e conforto para o usuário).

Some basic Kotlin knowledge is needed. The previous book of the same series fits this role perfectly.

Highly recommend the head first books for all the freshers whatever be the programming language. Written in such a way that it will make your core concepts clear and strong.

Muy buen libro para los que no saben nada de nada de Android ni programación. Para los que tenemos cierta experiencia programando puede resultar redundante en muchas explicaciones.
