Question on Head First Android

Hi David & Dawn,
Thanks for clarifying my question on the welcome thread

I have a follow up question. Does this book discuss the key aspects of develop, test, build, deploy, run aspects of Android apps?

Thanks,
Raghu

Hello Raghu,

Yes we do discuss what happens when you build your app and how it gets installed on your app. We have a small amount of information on testing and how to publish your app to a store, but sadly (at 890 pages!) we couldn't afford to give it a huge amount of space.

We did a course for O'Reilly Media about a year or so ago on Android Internals, and that went into a *huge* amount of depth about how source code becomes JVM bytecode, which becomes Dalvik code, then an APK, then gets on-the-fly compiled into ARM machine code on the device itself. That's a level of detail we could never include in a book like HFAD, but if O'Reilly became convinced there was a demand for it, I'm sure they'd be happy for it to be run again

On testing, Google do provide quite good documentation for the fundamentals:

Compose Testing is a little different and is built on the semantic infrastructure:

Hi David and Dawn,

I use Tailwind CSS for some dev projects. Does your book address using Tailwind CSS or Tailwind UI Components in Android Apps?

Thanks,

Geoff

Hello Geoff,

No, we look exclusively at Android native development.
