M Merlot2309 Active Member Licensed User Longtime User Apr 13, 2011 #1 Hello, At this moment I do have some questions about libs: 1. What is the difference between import and using a referenced lib? 2. Beside the 4 @ statements (ActivityObject, Permissions, ShortName and Version) what is needed to create a B4A lib? I guess that a B4A Lib differs from a Java/Android lib. 3. Finally found a good looking Java/Android calender project (https://github.com/jasonkostempski/Android-CalendarView) and I still don't know how to solve the error: cannot be resolved on the "import com.jasonkostempski.calendar.R;" line Sorry for my horrible use of terminologie Thanks in advance! Helen.

If you do not use import then you will need to write the full name of every class with the package. 2. B4A lib is a regular jar file (regular Java lib). 3. R files in Android are classes that should be generated automatically during compilation.
