A Vectordrawable cannot be converted into a normal drawable.

android.graphics.drawable.VectorDrawable cannot be cast to android.graphics.drawable.BitmapDrawable

So i guess you are using Vectordrawables?

Please note that vectordrawables are a Android 6 Feature and are not useable on older android devices if you are not using a library wehich support vectordrawables.

See for ex. https://www.b4x.com/android/forum/threads/vectordrawables.68801/#content
Or https://www.b4x.com/android/forum/threads/vectorcompat-morphbutton.71553/

 

[dragonguy]

but i didin't use Vectordrawable , i just GetApplicationIcon from
PackageManager.

 

[DonManfred]

In this specific case the app (one of the app you get listed by the packagemanager) is using an Vectordrawable i guess....

 

[DonManfred]

I suggest to add a Check for the type of

pm.GetApplicationIcon(s(1))

before you use it as a drawable.

 

[Erel]

Dim drawable As Object = pm.GetApplicationIcon(...)
If drawable Is BitmapDrawable Then
 Dim bd As BitmapDrawable = drawable
 'scale it as needed
Else
 'set it as the background of a view
 ImageView1.Background = drawable
End If
