Downloaded: ahaActionBar.zip, Astro 1.4.zip, BetterDialogs v2.11.zip and ScrollView2D v1.3.zip. Then I put the -jar files in D:\B4x\AdditionalLibraries\B4A and .xml files in D:\B4x\AdditionalLibraries\B4XlibXMLfiles.
Your error is here.
You should save xml files only for b4xlib libraries.
For ALL additional B4A libraries which have a x.jar and a x.xml file, both must be saved in D:\B4x\AdditionalLibraries\B4A folder.
I'm afraid that you misunderstood the text in the guide:
B4X > Folder for B4X libraries
B4XlibXMLFiles > Folder for B4X libraries XML files.
B4X > Folder for B4X libraries means only libraries with the
b4xlib extension
B4XlibXMLFiles > Folder for B4X libraries XML files. means, xml files generated specifically for b4xlib libraries.
Summary:
For ALL additional B4A libraries which have a x.jar and a x.xml file, both must be saved in D:\B4x\AdditionalLibraries\B4A folder.
For ALL b4xlib libraries which have a x.b4xlib file, this one must be saved in D:\B4x\AdditionalLibraries\B4X folder.
By default, b4xlib libraries have no xml file! But, if you want xml files for b4xlib libraries you can generate those with the tool
Erel has developed and save only those files into the D:\B4x\AdditionalLibraries\B4XlibXMLFiles folder.
These files are useful for the
B4X HelpViewer and the
[B4X] B4A, B4i, B4J and B4r API documentation - B4X Object Browser.
