Note that it is not a cheap library. You need to have a License per app.

Based on Erels answer here:
https://www.b4x.com/android/forum/threads/problem-building-library-for-smbj.104232/#post-653395

Based on this: Uncaught translation error: com.android.dx.cf.code.SimException: signature-polymorphic method called without --min-sdk-version >= 26
It uses a Java feature that is not available in older versions of Android.

when trying to run a (real basic) wrap for this

Sub Globals
    'These global variables will be redeclared each time the activity is created.
    'These variables can only be accessed from this module.
    Private HIChart1 As HIChartView ' It is part of the Layout...
End Sub
Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    Activity.LoadLayout("Layout1")
    Dim s As HISeries
    s.Initialize
    Dim d As HIData
    d.CsvURL = "https://www.highcharts.com/studies/data.csv"
    Log(d.Params)
    s.addPoint(d)
    HIChart1.addSeries(s)
End Sub

and getting this error

I guess the same applies here. I am using the AAR which i downloaded and a librarywrap i wrote.

On their website they promote

The wrapper works with Android 4.4 and newer.

but based on the error message i got i fear that one need to have an Android 8+ Device.
