Android is an evolving platform and B4A, the world’s easiest rapid Android app development tool, evolves to keep up. Niche publisher Penny Press publishes and gives away free updates of their best-selling book by in-house author Wyken Seagrave.
Android is the world’s favourite mobile operating system. IDC predicts  Android shipments will constitute 81% of the smartphone market in 2015. But Android is a constantly developing platform, making it difficult for app developers to keep up. Further, Android apps are written using Java, which is not the easiest language to learn and use well.
That is why B4A was written by Anywhere Software . It aims to be the easiest rapid Android app development tool available, allowing complete beginners to create powerful Android apps using the easily learned BASIC language. And the success of B4A is testified by the community of tens of thousands of users all over the world, including NASA, HP and IBM.
Anywhere Software is constantly updating the tool, which makes it almost impossible for any large publisher to create a book which keeps in step. Only a niche publisher, such as Penny Press  with an author who is skilled both in software development and writing effective user manuals, such as Wyken Seagrave , is capable of constantly updating their book.
And Penny Press offer something which (as far as they know) is unique in the publishing industry: free updates to the latest edition of the book for previous customers. Those who buy the e-book edition (available in 3 different formats) from the Penny Press store  can update their book at any time using a dedicated upgrade page .
This unique level of service has made “B4A: Rapid Android App Development using BASIC” by Wyken Seagrave the world’s best-selling book dedicated to deliver a comprehensive reference guide to the B4A user interface and language, to explain and illustrate every keyword, object and core library. It has just been updated to cover version 5.50 of B4A.
