setCloseButtonIcon() method doesn't change default Close button

Question

I try to change default icon for Close Button in Chrome custom tabs (CustomTabsIntent.Builder)

Simple code for testing:

Bitmap closeIcon = BitmapFact         


        

Answer 1

The close icon needs to be 24dp x 24dp. Something like this:

In Kotlin, you can retrieve this drawable and add it to your builder like this:

AppCompatResources.getDrawable(main, R.drawable.close_icon)?.let {
            DrawableCompat.setTint(it, Color.WHITE)
            builder.setCloseButtonIcon(it.toBitmap())
        }
