Hi Marco
This looks a great addition to b4x library. Unfortunately I have no access to buy it now from where I am. Hopefully will be able to do so next month.
Thanks for the effort.

Hi Marko, why don’t you publish the book in other formats? It will be welcome

Thanks Marco, I bought the book on Amazon and am proceeding with the reading. I'm a complete novice with this language so I greatly appreciate this guide for a beginner.

I keep getting the error message:
An error occurred.
Error parsing program
Error description:
Use of undeclared array:Flags (or in my case Cats)
Error occurred on line: 55 (Main)
55 Cats(x)=Rnd(1,4)

I used only 4 images of cats.
Obviously I don't know how to declare the array. In Sub Globals I added the line 'Dim Cats As String'. Can you aim me in the right direction?
Thanks
3/17/18 I got that problem solved.

Marco made a good attempt at giving me a practice app to construct. However, since I'm a beginner I have experienced a good deal of confusion with some of the directions given during the production of the app. I'm now unsure how to get clarity on those instances of confusion so I'm in need of support which I can't find either here in the thread or elsewhere.

If you have found flaws in Marko's book, he should be keen to help you because it will improve his book. Since I haven't downloaded or read his book, I can only offer a suggestion.

Dim Cats(10) As String 'Assuming Cats is a string array that will hold 10 string elements

If you haven't already done so, you need to read and play with Klaus books, the latest being his Booklets:
https://www.b4x.com/android/forum/threads/b4x-documentation-booklets.88985/#post-562952

and his Beginners Guide https://www.b4x.com/android/forum/threads/b4a-beginners-guide.9578/
and User Guide https://www.b4x.com/android/forum/threads/users-guide.15861/

Hope this helps.

Thanks Widget I'll do both of your suggestions.
