Android Question [SOLVED] B4XDrawer error with custom font

[Brandsum]

Hi everyone,

I'm using the latest version of B4XDrawer in my project. And I'm using a custom font for my application.

It is compiling without any error. But when the app runs on the device I'm getting this error:

** Activity (main) Resume **

This is how I've included the custom font:

CreateResource(font, hindsiliguri.xml,
<font-family xmlns:android="http://schemas.android.com/apk/res/android">
    <font
        android:fontStyle="normal"
        android:fontWeight="400"
        android:font="@font/hindsiliguri_light" />
    <font
        android:fontStyle="italic"
        android:fontWeight="400"
        android:font="@font/hindsiliguri_light" />
</font-family>
)

CreateResource(values, theme.xml,
<resources>
    <style name="MyTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="android:typeface">@font/hindsiliguri_light</item>
    </style>
</resources>
)

Error occurred on line: 228 (B4XDrawer)

Public Sub getCenterPanel As B4XView
    Return mCenterPanel
End Sub

How can I solve this error?
