Android Question Conditional inclusion of a B4A Library

    I would like to conditionally include a regular B4A library, say FusedLocationProvider, so that I can omit it in builds that do not require it but include it when needed.

    Erel suggested that it would involve using

    Code:
    #If FLP  
        #AdditionalJar: FusedLocationProvider
    #End if

    So I omitted FusedLocationProvider from the list of libraries, hoping that would work.
    However if I do that then this statement fails to compile:

    Code:
    #If FLP
        Dim FLP1 As FusedLocationProvider
    #End If

    So not quite so simple as I hoped. However I've heard that there might be a solution :)
    hopefully not too complicated!

    It seems like what is needed is a conditional deletion of a jar/library file at compile time, so that the editor still recognises the elements of an included library but then they are removed before compilation.

    The FusedLocationProvider library itself is quite small (less than 100kb). The problem is that it depends on google-play-services.jar which is a large jar (3m+).

    The solution is:
    1. Edit FusedLocationProvider.xml and remove the DependsOn line (near the bottom).
    2. Keep the library checked in the IDE.
    3. Conditionally add google-play-services.jar with #AdditionalJar: google-play-services
