Android Canvas Paint: getTextBounds() ignores system font

Question

paint.getTextBounds(text, 0, text.length, textBounds)
...
canvas.drawText(text, canvas.width/2F - textBounds.exactCenterX(), canvas.height/2F - textBounds.exactCenterY(), paint)

I am using getTextBounds() to center text in a circle graphic. And while it looks fine with the system's default font ( left screenshot ), the text slides to the left of the circle center when I change the system font ( right screenshot ):

The 103 and 234 look particularly bad to me. The font I chose is Choco Cooky on a Samsung Galaxy S7.

I put a debug print after the titular line of code and discovered it returns the same bounds regardless of typeface chosen , which would explain the result since the letters of Choco Cooky are smaller. However this behavior seems like a bug to me.

What can I do to get an accurate measurement of a text's bounds that respects the system font?

One approach might be to use a TextView with a ShapeDrawable as background, which then gets converted into a Bitmap so it can be used as a Google Maps marker. However this sounds like a lot of rewriting without any guarantee it will fix the issue.
