Problem with clearPackagePreferredActivities

[Informatix]

I don't know if there's a bug in my code or in B4A, but I'm unable to clear any activity mapping with clearPackagePreferredActivities. The goal is to remove my app as the default home screen. But when I use the reflector library to call clearPackagePreferredActivities with the package name as parameter, I get "ClassNotFound flm.b4a.playground" ("flm.b4a.playground" is my package name). Since many (Java) users reported that it works, I'm wondering why I get this message.

Can you post your reflection code?

Dim r As Reflector
Dim PN As String = r.GetStaticField("anywheresoftware.b4a.BA", "packageName")
Log(PN)
r.Target = r.GetContext
r.Target = r.RunMethod("getPackageManager")
Log(r.Target)
r.Target = r.RunMethod2("clearPackagePreferredActivities", "java.lang.String", PN)

Log result:
** Activity (main) Create, isFirst = true **
** Activity (main) Resume **
flm.b4a.playground
android.app.ApplicationPackageManager@415ef490

The second parameter is the value and the third is the type.
