Hi Jeff,

I have a couple of questions for you:

1. Does this book cover dependency injection frameworks, like RoboGuice, or is aimed for starters?
2. What do you think about Android Studio, built on top of IntelliJ IDEA?
3. What version of Android is required to follow your book? (I am sick of 2.x tutorials, it is hard to pick up Android development this way )

Thank you very much!

Hi Silviu,

Here are my answers to your questions:

1) The book doesn't cover dependency injection frameworks.

2) I've never used Android Studio or IntelliJ IDEA. My book briefly introduces Eclipse in Chapter 1 and then uses Eclipse in Appendix C "Getting Started with Android."

3) The book is Android-version agnostic. However, Appendix C requires Android 4.4.2.

The book covers the Java language and key APIs that are also useful to Android (e.g., Collections Framework). Appendix C is distributed as a 96-page PDF file included in the book's code file. I couldn't fit it into the book's 1200-page limit. Even if I could have fit it in, I wouldn't have done so because the book emphasis is on learning Java as a prerequisite to getting into Android development.

If you would like a free copy of Appendix C, point your browser to http://www.apress.com/9781430264545, click the Source Code/Downloads tab, and click the Download Now link on this tab to download the book's code file, which includes the Appendix C PDF including all code for its Android apps.

All the best.

Jeff

Hi Jeff,

Thank you for all the answers. I have one final question: what is the main requirement to be a great Android developer? Skills, connections, patience, something else?

Best,
Silviu

Hi Silviu,

I think that patience is very important because there is much to learn (resources, screen resolutions/densities/DP/SP, activity architecture, intents, XML-based layouts and manifest, views, view groups, and so on). To become a very good Android developer, you should also have a desire to learn. One way to do this is to self-educate by creating many small apps that demonstrate various APIs and other Android concepts and write small articles for yourself that introduce the apps and what they accomplish, what they demonstrate, how to build them at the command line and in other contexts, and so on. Search the Internet and record various tips [and ask questions] to help yourself learn even more. I believe that patience and this self-education will help you become a great Android developer.

All the best.

Jeff
