Hi.
I'm here to report a possible bug in an internal lib (B4XDrawer).
When you set a background color via manifest, the color covers b4xdrawer.
XML:
<item name="android:background">#ff039be5</item>
When using this for example, nothing is displayed on the screen, just an empty screen with the color above.
The problem is really in the Drawer, because if I don't load the layout in the drawer, and load it directly in the root.loadlay.... it works perfectly.
