Android Question Canvas Letters Appear Different on Different Devices

[Guardian17]

I am trying to generate a background theme for a word game. Random letters are placed at somewhat random positions and orientations across a background Canvas. I want the theme background to be different each time the game is played. The code is below.

The problem I am having is that on my GalaxyS3 smartphone (running Android 4.1.2), the letters appear wholly-formed and filled-in (which is what I want), but on my Nexus10 tablet (running Android 4.4.2), only the outlines of the letters are visible with no fill. The exact same APK file is being run in debug mode on both devices (using the B4A Bridge).

Is there some "fill" parameter or specification I am missing? Is the problem related to the Android operating system version, or is it specific to the Nexus device?

Thanks, Steve! Copying the new core.jar file to my Libraries folder worked JUST FINE! Now the letters appear properly on my Nexus 10.
