Android programming with android studio book code

Question

See more:

I'm working through the book Beginning Android Programming with Android Studio, 4th Edition and I'm hoping the title is familiar to someone here.

I've gotten up to chapter 3, but now nearly every example (that we're optionally supposed to type in) that I've typed in won't build, because named resources specific to (I assume) the example are missing from the generated R.java file.

The book mentions no resources, so I'm hoping someone has had the same experience and resolved it, and can share with me how they did it.

BTW, if I download the code sample for that same chapter, it works fine, but I want to enter the code myself and get used to it, not just copy-paste.

What I have tried:

There is nothing I know or can guess how to do.

Are you downloading it from here?

Have you checked with the book's author to see if some of the examples are known to be faulty?

What is the exact error you are facing?

Are you using Eclipse or Android Studio? If the latter, have you tried cleaning the project (to force the R.java file to be rebuilt)? Eclipse has this same functionality but it's been a while since I've used it.

"The book mentions no resources..."
I've never seen or coded an Android app that was void of any resources (i.e., they all have them).

I have asked about it on the Wrox forums; I have no contact info for the author. I never said the app is void of resources. I said there are missing resources and the book mentions no resources. I'm using Android Studio and will try the clean, thanks. I never knew about that.

You have most likely missed something that you need to type in. Check the res directory in your application source tree.

I have missed nothing; I have gone through the book's exercise 4 or 5 times, and how will looking at the res folder tell me what's supposed to be there. If I recognise something in res, I don't know if it's right or wrong, and the book gives no values for any resources.

Well without a copy of the book and sight of your code it is anyone's guess what the problem is. I suggest you post the code into your question and we may be able to suggest something.

I just downloaded the source code for Chapter 3 and all the samples come complete with their resource files. So if you do not see anything in the book about adding this information (which certainly seems odd) the only person to ask would be the author.

Solution 1

I got through the chapter 3 in question with downloaded code in the end. Chapter 4 includes instructions for adding a used resource, but no source code. I guess I just have to improvise at some places.
