QML embedding example Java part doesn't look good on low pixel densities

Earlier the example looked weird on my emulator, but I forgot about it due to other tasks and I also thought that maybe the graphical glitches we saw with changing the orientation might be related. But alas, it was not so.

So running the example on different AVDs showed a way different looking Java part. After a bit of looking at config files and trying some options it's the low DPI displays that were looking especially weird. I guess the Java part doesn't scale to different pixel densities. Screenshots should show this well - 120dpi, 160dpi, 240dpi and 320dpi are attached below. The resolution was always set to 1080x1920.
