Hello Raghavan,
Thanks for your questions.
1. Regarding what distinguishes our book from the other Android books out there, please see this post where the same question is answered by Lucas:

2. Like with most architectures that embed one language environment within another, the main challenges are the sharing of data structures, calling code across environment boundaries, exception reporting, security concerns related to trusting code that that calls internal code from external script code etc.
3. The book covers authentication in scenarios such as when the Android application calls a device external service such as Google App Engine, Facebook, or Twitter.

Congratulations on your book. I had seen the description of the book in Amazon.
I have a few questions.
1. How different is your book from other Android books?
2. What are the challenges while interacting/binding the Android apps with LUA, SL4A etc.,?
3. How about covering any security/authentication aspects in android? Does it have any inbuilt features?
Thanks in advance.
Cheers,
Raghavan alias Saravanan M
