You want to use TYPE_MAGNETIC_FIELD this way, instead of GRAVITY. GRAVITY I
haven't seen before but the accelerometer is actually a gravity sensor, so
I'm wondering if its the same data for each?
Also down the line you will want to minimize the allocations in methods like
this especially if they're getting called many times per second. Not sure
if using System.arraycopy from event.values to your temporary array will
give a ton of performance over cloning; I haven't timed it, but things like
that can sometimes make a big difference. Same with allocating the matrix
of float[16] for instance on each call, definitely want to avoid that.
I'm going to guess that with MAGNETIC_FIELD+ACCELEROMETER this should work
okay. Just know that the values WILL get wacky as you approach certain
pitches.
