The great part about Android being open source is that you can go look at the source to see that the UI thread is not a "normal priority" thread [0]. There are very few things that run at higher priority (and they're listed right there): the threads related to audio and the hardware interaction (power buttons, etc.).

Last time I tried it, Android did not let you create a thread with higher priority than the UI thread.
